Uranus has an orbital period of 84.07 years. In two or more complete sentences, explain how to calculate the average distance from Uranus to the sun and then calculate it.
The formula is p^2=a^3

Answers

Answer 1
The Average Distance from Uranus to the Sun is 27.506. One way to solve this is by doing the oppsite of how you find the orbitial period. The way you find the orbitial period is by raising the distance to the 3rd. So what i did was take the square root of the orbitial period which is 9.16 and multiplied it by 3 to get 27.506. 

Answer 2

Answer:

Average distance from Uranus to the sun, a = 2.88 billion km

Explanation:

It is given that,

Orbital period of Uranus, T = 84.07 years = 2.65 × 10⁹ s

We have to find the average distance from Uranus to the sun. It can be calculated using Kepler's third law as :

[tex]T^2\propto a^3[/tex]

or [tex]T^2=\dfrac{4\pi^2}{GM}a^3[/tex]

Where

T is orbital period

a is the average distance from Uranus to the sun

G is universal gravitational constant

M is mass of sun, [tex]m=1.98\times 10^{30}\ kg[/tex]

[tex]a^3=\dfrac{T^2GM}{4\pi^2}[/tex]

[tex]a^3=\dfrac{(2.65\times 10^9)^2\times 6.67\times 10^{-11}\times 1.98\times 10^{30}}{4\pi^2}[/tex]

[tex]a^3=2.34\times 10^{37}\ m[/tex]

[tex]a=2.86\times 10^{12}\ m[/tex]

a = 2.88 billion km

Hence, this is the required solution.

Answers

Your answer should be B.) 10

The atomic mass of an element is the sum of the element's protons and neutrons. The atomic number of an element is equal to its number of protons. To find the amount of neutrons in an atom, subtract the atomic number from the atomic mass. 19 - 9 = 10.

Hope this helps!

To see the number of atoms of an element in a given molecule we need to multiply stoichiometry to the number that is written on the foot of the element that is stoichiometry. Therefore, the number of neutron is 10.

What is atom?

Atom is the smallest particle of any element, molecule or compound. Atom can not be further divided. Atoms contains nucleus in its center and electron that revolve around the atom in fixed orbit.

In the nucleus, proton and neutron are present. Electron has -1 charge while proton has +1 charge. Neutron is neutral that is it has no charge. So overall the charge of nucleus is due to only proton, not by neutron.

Atomic number= number of proton=number of electron

Mass number= number of proton/electron + number of neutron

Mass number=19

atomic number =9

substituting all the given values in the above equation, we get

19=9 + number of neutron

number of neutron=10

how are igneous rocks formed?
step by step please.

Answers

When it comes to the composition of the Earth, three main types of rock come into play. These are known as metamorphic rock, sedimentary rock, and igneous rock, respectively. Also known as “fire rock” (derived from the Latin “ignus”), these type of rock are the most common type of rock in the Earth’s surface. In fact, combined with metaphoric rock, igneous rock makes up 90 to 95% of all rock to a depth of 16 km from the surface.

Igneous rocks are also very important because their mineral and chemical makeup can be used to learn about the composition, temperature and pressure that exists within the Earth’s mantle. They can also tell us much about the tectonic environment, given that they are closely linked to the convection of tectonic plates. But just how are these rocks formed?

In essence, igneous rocks are formed through the cooling and solidification of magma (or lava). As hot, molten rock rises to the surface, it undergoes changes in temperature and pressure that cause it to cool, solidify, and crystallize. All told, there are over 700 known types of igneous rock, the majority of which are formed beneath the surface of the Earth’s crust. However, some are also formed on the surface as a result of volcanic activity.

Those that fit into the former category are known as intrusive (or plutonic) rocks, while those that fit into the latter are known as extrusive (or volcanic) rock. In addition to these, there is also hypabyssal (or subvolcanic rock), a less common form of igneous rock that is formed within the Earth between plutonic and volcanic rocks. hope that helped

A mug rests on an inclined surface, as shown in (Figure 1) , θ=17∘.
What is the magnitude of the frictional force exerted on the mug?
What is the minimum coefficient of static friction required to keep the mug from sliding?

Answers

Refer to the figure shown below.

g =  9.8 m/s², the acceleration due to gravity.
W = mg, the weight of the mug.
θ = 17°, the angle of the ramp.

Let μ = the coefficient of static friction.

The force acting down the ramp is
F = W sin θ = W sin(17°) = 0.2924W N
The normal reaction is
N = W cosθ = W cos(17°) = 0.9563W N
The resistive force due to friction is
R = μN = 0.9563μW N

For static equilibrium,
μN = F
0.9563μW =0.2924W
μ = 0.3058

The frictional force is F = μN = 0.2924W
The minimum value of μ required to prevent the mug from sliding satisfies
 the condition
R > F
0.9563μW > 0.2924W
μ > 002924/.9563 = 0.306

Answer:
The frictional force is 0.2924mg, where m = the mass of the mug.
The minimum coefficient of static friction is 0.306

The magnitude of frictional force exerted on the mug is [tex]\fbox{\begin\\\left( {2.865} \right)m\end{minispace}}[/tex] and the coefficient of static friction is [tex]\fbox{\begin\\0.31\end{minispace}}[/tex].

Further explanation:

The opposition that every object feels when it moves is known as the frictional force. This is an opposing force. It always acts in the opposite direction of the motion of the object.

Given:

The angle of inclination of plane is [tex]{17^ \circ }[/tex].  

The acceleration due to gravity is [tex]9.8\,{\text{m/}}{{\text{s}}^{\text{2}}}[/tex].

Concept used:

The frictional force is defined as the opposition of motion of any object or body.  It is also defined as the product of coefficient of friction to the normal force exerted on the body.

The expression for the net force exerted on the mug is given as.

[tex]{F_{{\text{net}}}} = mg\sin \theta[/tex]                                                                         …… (1)

Here, m is the mass of the mug, g is the acceleration due to gravity and [tex]\theta[/tex]  is the inclination angle.

The force that keeps the body at rest is known as the static friction force. It also acts in the opposite direction of motion of body.

The expression for the static frictional force is given as.

[tex]{F_s} = {\mu _s}N[/tex]                                                              ..…. (2)

Here, [tex]{\mu _s}[/tex] is the coefficient of static frictional force and N is the normal force exerted on the body.

When mug is placed on the inclined plane the static frictional force is equal to the frictional force. The vertical component of weight is balanced by the normal reaction of the mug.

The expression for the normal force is given as.

[tex]N - mg\cos \theta=0[/tex]

 

Rearrange the above expression.

[tex]N = mg\cos \theta[/tex]

 

Substitute [tex]mg\cos \theta[/tex]  for N in equation (2).

[tex]{F_s}={\mu _s}\left( {mg\cos \theta } \right)[/tex]

 

Here static frictional force is same as the frictional force exerted on the mug.

Substitute [tex]mg\sin \theta[/tex] for [tex]{F_s}[/tex] in above expression and rearrange it.

[tex]{\mu _s} = \dfrac{{\left( {mg\sin \theta } \right)}}{{\left( {mg\cos \theta } \right)}}[/tex]

 

Rearrange the above expression.

[tex]{\mu _s} = \tan \theta[/tex]                                   …… (3)

The mass of a basketball is three times greater then the mass of a softball. Compare the momentum’s of a softball and a basketball if they both are moving at the same velocity.

Answers

Let m = the mass of the softball.
Then the mass of the basketball is 3m.

By definition, momentum =  mass * velocity.
If both the softball and basketball move at the same velocity, v, then
Momentum of the softball = mv
Momentum of the basketball = 3mv

Answer: The momentum of the basketball is 3 times that of the softball.

Final answer:

Momentum depends on mass and velocity, and in this scenario, the basketball will have three times more momentum than the softball despite moving at the same velocity. Understanding momentum is key in analyzing the effects of collisions and interactions involving objects of different masses and velocities.

Explanation:

Momentum is a measure of how hard it is to stop an object and depends on both mass and velocity. The momentum of an object (p) is given by the product of its mass (m) and velocity (V): p = mV. In the given scenario, if a basketball has three times greater mass than a softball but both are moving at the same velocity, the basketball will have three times more momentum compared to the softball.

This difference in momentum reflects the impact a player with a greater mass but the same velocity can have in collisions, as momentum is crucial in determining the effect of such interactions. Therefore, if the mass of the softball is m, and the velocity of both the softball and basketball is v, then the momentum of the softball will be m × v and the momentum of the basketball will be 3m × v, which is three times greater than that of the softball.

m = subject mass
r = distance between to objects


Given: 
Earth's Mass (M1) = 5.972x10^24 kg
Eath's Radius (R1) = 6371 km = 6371000 meters
Venus' Mass (M2) = 0.8*( 5.972x10^24 kg) =4.7776x10^24 kg
Venus' Radius (R2) = 0.95*(6371 km) = 6052.45 km = 6052450 meters


Required: Mass on Venus (m2)

Solution:
We know that F1 and F2 for both planets are the same. Thus we equate the formula, we get

G*M1*m1/(R1^2) = G*M2*m2/(R2^2)

G is common for both, so we eliminate G
M1*m1/(R1^2) = M2*m2/(R2^2)
 (5.972x10^24)*m1/(6371000^2) = (4.7776x10^24)*m2/(6052450^2)

An electron is ejected horizontally at a speed of 1.5 ✕ 106 m/s from the electron gun of a computer monitor. if the viewing screen is 35 cm away from the end of the gun, how far will the electron travel in the vertical direction before hitting the screen?

Answers

Final answer:

The electron, ejected horizontally and not influenced by external forces such as gravity, magnetic, or electric fields, would have a vertical displacement of zero and thus would travel directly to the screen without any vertical deviation.

Explanation:

An electron ejected horizontally with a speed of 1.5 × 106 m/s from an electron gun will continue to move in a straight line horizontally in the absence of any external forces. Since there is no mention of gravity, magnetic fields, or electric fields in the stated problem that could cause the electron to deviate from its path, the vertical displacement of the electron before hitting the screen would be zero if we disregard such forces. Hence, the electron will travel horizontally and hit the screen without any vertical displacement.

Explanation:

To solve this problem we must apply Newton's second law of motion, and it states:

"The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object."

[tex]F=m*a[/tex]

Being:

F= net force

m=mass of the object

a= acceleration

As acceleration is inversely proportional to mass, we conclude that to have fastest acceleration Beth should use the lighter ball of 3.2Kg mass.

A car has a mass of 1000 kg and accelerates at 2 meters per second per second. what is the magnitude of the net force exerted on the car

Answers

F=ma
Therefore the net force = 1000kg × 2 metres per second per second
So F=2000 N

Answer:

The magnitude is [tex]2000N[/tex]

Explanation:

To solve this question we are going to use the second Newton law.

The second Newton law states that the acceleration of an object is directly proportional to the net force which acts on the object and inverse proportional to the mass of the object ⇒

[tex]a=\frac{F}{m}[/tex]

Which can also be written as :

[tex]F=m.a[/tex] (I)

Where F is the force

Where m is the mass of the object and where ''a'' is the acceleration.

In the problem, we know that

[tex]m=1000kg[/tex]

[tex]a=2\frac{m}{s^{2}}[/tex]

If we replace in the equation (I) :

[tex]F=(1000kg).(2\frac{m}{s^{2}})=2000(kg.\frac{m}{s^{2}})[/tex]

The unit [tex]kg.\frac{m}{s^{2}}[/tex] is defined as N which is called Newton. N is an unit of force.

Finally, the net force exerted on the car is [tex]2000N[/tex]
