a plane travels 2.5 km at an angle of 35 degrees to the ground and then changes Direction and travels 5.2 km and an angle of 22 degrees to the ground what is the magnitude and direction of the Plains total displacement

Answers

We can solve for the resultant x and y components by using the sine and cosine functions.

resultant x = 2.5 cos 35 + 5.2 cos 22 = 6.87 km

resultant y = 2.5 sin 35 + 5.2 sin 22 = 3.38 km

The resultant displacement is calculated using hypotenuse equation:

displacement = sqrt (6.87^2 + 3.38^2)

displacement = 7.66 km

The resultant angle is:

θ = tan^-1 (3.38 / 6.87)

θ = 26.20°

Therefore the magnitude and direction is:

7.66 km, 26.20° to the ground

The answers are as follows:
1. B.
A typical atom is made up of three different particles, which are electron, proton and neutron. The proton and the neutron are located inside the nucleus of the atom while the electron orbit round the nucleus.
2. C
The number of proton in an atom determines the atomic number of that atom. Atom are positively charged particles and they do no participate in chemical reactions. The number of proton of an element remain constant at all time while the number of neutrons and the electrons in the atom may change.
3. B.
The first periodic table was created by Dmitri. He arranged the periodic table in such a way that, elements with similar properties fall into the same column in his periodic table. This was because, he arranged the periodic table on the basis of their physical and chemical properties.
4. A
The elements in the periodic table are arranged in horizontal row and vertical column. The column on the periodic table divides the elements into groups.
A row of element on the periodic table is called PERIOD. For elements on the same period, they have the same number of atomic orbitals.
5. A
Chemical symbol refers to the one or two letters which are used to represent a particular element. Chemical symbols are derived in a variety of ways. The chemical symbols make it possible for one to recognize an element quickly and to write it in an abbreviated form when writing chemical equations.
6. A.
An object is said to be ductile if it can be pulled into a long wire. It refers to an element's capacity to be pulled into a thin wire without the element been deformed. This is one of the properties of metals. Ductability makes it easier for one to work with a metal.
7. C
When metals atoms react with other atoms, the metal atoms lose electrons, this is because, metals usually have a low number of electrons in their outermost shells, which they always preferred to donate in order to achieve octet form.
8. B
Particle accelerator is a machine that accelerate elementary particles to very high energies, thus producing beam of charged particles which can be used for a lot of different purposes.

how did Bourne believe that an object could be made to rise or sink at will?

Answers

Bourne believed that an object would float or sink at will as long as he could manipulate the effect's of buoyancy which control and object to sink or float. Hope this helps!

Explanation:

When an object is placed inside water, an upward force is exerted by water called as buoyant force.

An object will float or sink, this completely depends on the density of object. Also, if the magnitude of gravitational force is more as compared to the buoyant force the object will sink otherwise float.

If the density of substance is more than water, it will sink and if the density of substance is less than water it will float.

How does a centripetal force cause circular motion

Answers

This acceleration is directed towards the center of thecircle. ... So for an object moving in a circle, there must be an inward force acting upon it in order tocause its inward acceleration. This is sometimes referred to as the centripetal force requirement.

Answer:

It cause the change in the direction of the motion at every instant of time

Explanation:

When an object is revolving around a fixed point with uniform speed then in that case the acceleration of the object tangential to the path must be zero.

which mean the component of acceleration along the speed of the object at all instant of time will zero or not present because it's speed must remains the same

now since the direction of motion is continuously changing here so we can say that the force must acting here in such a way that will cause the change in the direction of the object

So this force must be perpendicular to the velocity at all instant so that the magnitude of velocity will remain the same while the direction of the velocity will continuously changing

So centripetal force will always act along the center of the path of the object

besides mass , another factor that affects force

Answers

I would say direction because force needs to be directed

Force, mass, & acceleration are needed in the equation

so your answer is acceleration

how do I figure out the GPE of an object on the ground? question 28.

Answers

In this scenario, only conservative force is acting on the ice-cream hence energy is conserved.
Now, you know that ice-cream was held at a height of 1.75 m from ground. Taking ground( h= 0 meters) as reference,

Total energy of ice-cream before it fell = Total energy after it reached the ground.

Once ice-cream falls, all its GPE is converted into kinetic energy. Kinetic energy will be maximum just before it hits the ground. And since ice-cream is inelastic substance, it will come to at rest. That is, its GPE will be zero on the ground

On a hot summer day several swimmers decide to jump into a river. They step off the bridge and strike the water at 1.5s later. Ignore air resistance. What is the height of the bridge?
I did it but I don’t know if it’s right

Answers

The only equation you need is the Δy = v₀t + 1/2at², and in this case, v₀t = 0 because the swimmers are starting from rest. Therefore, Δy = 1/2at², and that is 1/2 x (10m/s²) x (1.5)² = 11.25m.
With sigfigs it is 11m.

When on a hot summer day several swimmers decide to jump into a river. They step off the bridge and strike the water 1.5 seconds later. Ignore air resistance, then the height of the bridge would be 11.03 meters.

What are the three equations of motion?

There are three equations of motion given by Newton,

v = u + at

S = ut + 1/2×a×t²

v² - u² = 2×a×s

As given in the problem, when on a hot summer day several swimmers decide to jump into a river. They step off the bridge and strike the water 1.5 seconds later. Ignore air resistance,

By using the Second equation of motion,

S = ut + 1/2×a×t²

S = 0 + 0.5*9.81*1.5²

S = 11.03 meters

Thus, the height of the bridge would be 11.03 meters.

Describe what would happen if, while wearing rollerskates, you pushed as hard as you could against a wall. Why does this happen?

Answers

You would roll backwards. This is because the wall is stationary while with you having the roller skates on makes you unstationary. The force you put on the wall does nothing to the wall but instead goes back to push you. Again this is because the wall is stationary and is not going anywhere.

If you were wearing roller skates and pushed as hard as you could against a wall you would be slung backwards. This happens from you pushing yourself & from gravity .

Answers

Distance can be equal to displacement ... if the motion is all in a straight line ... but distance can never be greater than displacement.

Yes, it is possible that the distance can be equal to the displacement. a further explanation is given below.

A intervals metric that is taken somewhere across a track could be determined as the Distance, and the measurement of just a specific duration or short timeframe could be considered as a Displacement.Whenever you walk down the road throughout the one manner, the distance, as well as the size of the whole movement, become equivalent or comparable.
