When an objects mass increases its gravitational pull ____ a.decreases b.increases c. Stays the same
As the mass of an object increases, its gravitational pull increases.
What is gravitational force?The gravitational force is the attractive force that one body applies on the other by virtue of its mass. For two objects of mass (M) and (m) separated by a distance (r) apart, the gravitational force of attraction exerted by mass(M) on the other mass (m) is -
F[G] = GMm/r²
Given is that an object whose mass is increased.
Suppose that the mass of the object is (m) and after increasing its mass becomes (M) such that M > m.
Now,
M > m
Multiplying both sides by -
Gm[t]/r² ( m[t] is the test mass placed at a distance r away]
We get -
Gm[t]/r² × M > Gm[t]/r² × m
Gravitational force by Mass (M) > Gravitational pull by mass (m)
Therefore, as the mass of an object increases, its gravitational pull increases.

A computer is reading data from a rotating cd-rom. at a point that is 0.040 m from the center of the disc, the centripetal acceleration is 114 m/s2. what is the centripetal acceleration at a point that is 0.058 m from the center of the disc?
Final answer:
The centripetal acceleration at a point that is 0.058 m from the center of the disc is approximately 78.78 m/s^2.
Explanation:
To calculate the centripetal acceleration at a point that is 0.058 m from the center of the disc, we can use the formula for centripetal acceleration:
ac = (v^2) / r
Where ac is the centripetal acceleration, v is the velocity, and r is the distance from the center of the disc.
Given that the centripetal acceleration at a point 0.040 m from the center is 114 m/s^2, we can substitute the values into the formula:
114 = (v^2) / 0.040
Solving for v^2:
v^2 = 114 * 0.040
v^2 = 4.56
Taking the square root of both sides to find the velocity:
v ~ 2.14 m/s
Now we can calculate the centripetal acceleration at a point 0.058 m from the center:
ac = (v^2) / 0.058
ac = (2.14^2) / 0.058
ac ~ 78.78 m/s^2

A boy throws a ball up into the air with a speed of 8.2 m/s. the ball has a mass of 0.3 kg. How much gravitational potential energy will the ball have at the top of its flight?
Answer:
Gravitational potential energy, PE = 10.08 J
Explanation:
It is given that,
Speed with which the ball is thrown, v = 8.2 m/s
Mass of the ball, m = 0.3 kg
We need to find the gravitational potential energy of the ball when it is at the top of flight. The ball is thrown up into the air.
As per law of conservation of energy, the kinetic energy at the top is converted to gravitational potential energy as :
[tex]PE=KE=\dfrac{1}{2}mv^2[/tex]
[tex]PE=\dfrac{1}{2}\times 0.3\times 8.2^2[/tex]
PE = 10.08 J
So, the gravitational potential energy at the top of the flight is 10.08 Joules. Hence, this is the required solution.

Suppose you made some beef soup. you want to separate the extra fat from the soup before you eat it. how could you do that?
To remove the extra fat from beef soup, allow the soup to cool so that the fat solidifies and rises to the top. Then, use a spoon or ladle to skim off the fat.
Explanation:To separate the extra fat from the beef soup, you can use a simple method based on the principle of density. Fat is less dense than water, which causes it to float on the surface of the soup. Here are the steps you can follow:
Cool the soup: After cooking the soup, allow it to cool. As it cools, the fat will begin to solidify and rise to the top.Skim off the fat: Once the fat has risen to the top, you can remove it with a spoon or a ladle. Be careful not to remove too much of the soup along with the fat.If you want a more thorough fat removal, you can also place the cooled soup in the refrigerator. The fat will harden and can then be easily removed. This fat removal process ensures a healthier and lighter soup.

# SPJ2
Final answer:
The angular velocity of a solid sphere rolling without slipping down an incline depends on the sphere's radius and the incline's height, but not on the sphere's mass or the length of the incline.
Explanation:
When a solid sphere rolls without slipping down an incline, its angular velocity at the bottom depends on several factors. These factors include the radius of the sphere, the height of the incline, but not directly upon the mass of the sphere or the length of the incline (assuming it is long enough for the sphere to reach its maximum velocity due to gravity). The height of the incline determines the potential energy at the start, which converts into kinetic energy at the bottom. From the kinetic energy, we can find the linear velocity, and consequently the angular velocity, which is inversely proportional to the radius of the sphere.
The mass of the sphere does not directly affect angular velocity because both gravitational potential energy and rotational kinetic energy depend on mass in a way that it cancels out when calculating velocity. Similarly, the specific length of the incline does not determine the angular velocity at the bottom; rather, it is the vertical height that dictates the potential energy available for conversion to kinetic energy.

You are driving along a straight path with 100km/h for 46 minutes. How far do you get?
To find the distance traveled at 100 km/h for 46 minutes, convert the time to hours (46/60 hours), then multiply by the speed (100 km/h) to get approximately 76.67 kilometers.
To calculate how far you get when driving along a straight path at 100 kilometers per hour for 46 minutes, first, we need to convert the minutes into hours because speed is in kilometers per hour (km/h).
Convert 46 minutes to hours:
There are 60 minutes in an hour, so 46 minutes would be
46 minutes = 46 / 60 = 0.7667 hours (approximately).
Use the formula for distance:
Distance = speed X time.
Plug in the values and calculate the distance:
Distance = 100 km/h X 0.7667 hours
Distance = 76.67 kilometers.
Therefore, you would travel approximately 76.67 kilometers in 46 minutes if you maintain a constant speed of 100 km/h.

The fall time on planet X
Kinematics studies the movement of the carpus, establishing relationships between their position, speed and acceleration.
For this exercise we must solve it in parts:
1st part. We look for the distance that the body on the ground in the Earth
y = v₀ t - ½ g t²
Where y and, y₀ are the final and initial height, respectively, g the ground clearance and t the time
where as the body is released its initial velocity is zero
y- y₀ = - ½ g t²
Δy = - ½ 9.8 4.1²
Δy = - 82.4 m
2nd part. This same distance is the one that travels on planet X, we look for time
y - y₀ = - ½ a t²
indicates that the acceleration on planet X is
a = 1/5 g
we substitute
Δy = - ½ (1/5 g) t²
t = [tex]\sqrt{\frac{10 \ \Delta y}{g} }[/tex]
t = [tex]\sqrt{\frac{10 \ 82.4 }{9.8} }[/tex]Ra 10 82.4 / 9.8
t = 9.17 s

Suppose astronomers built a 150-meter telescope. how much greater would its light-collecting area be than that of the 10-meter keck telescope?
The light-collecting area of a 150-meter telescope would be 225 times greater than that of a 10-meter Keck telescope.
Explanation:In order to calculate the difference in light-collecting area between a 150-meter telescope and a 10-meter Keck telescope, we need to compare the areas of their mirrors. The area of a circle is determined by the square of its diameter. The Keck telescope has a mirror diameter of 10 meters, so its area is 100 square meters. The 150-meter telescope, on the other hand, would have an area of 22,500 square meters. Therefore, the light-collecting area of the 150-meter telescope would be 225 times greater than that of the 10-meter Keck telescope.

The light-collecting area of a telescope is directly proportional to the square of its diameter. To compare the light-collecting areas of two telescopes, we need to calculate the ratio of their areas.
Explanation:The light-collecting area of a telescope is directly proportional to the square of its diameter. To compare the light-collecting areas of two telescopes, we need to calculate the ratio of their areas. The area of a circular telescope is given by the formula A = πr², where r is the radius (which is half the diameter). So, for the 10-meter Keck telescope, the radius would be 5 meters, and its area would be A=π × (5)² m². For the 150-meter telescope, the radius would be 75 meters, and its area would be A=π × (75)² m². To find how much greater the light-collecting area of the 150-meter telescope is, we need to calculate the ratio A150/A10.
Where is the highest electronegativity found?
The highest electronegativity is found in fluorine, located at the upper right corner of the periodic table with a value of 4.0.
Explanation:The highest electronegativity is found at the upper right corner of the periodic table, with fluorine having the highest electronegativity value. According to the Pauling scale, developed by the Nobel Prize-winning chemist Linus Pauling, fluorine has an electronegativity value of 4.0, which is the highest of all elements. The periodic trends indicate that electronegativity values increase as you move from left to right across a period and decrease as you move from top to bottom down a group. Therefore, nonmetals, particularly halogens like fluorine, are usually the elements with high electronegativities.

A rock at rest has weight 138 n. what is the weight of the rock when it is accelerating downward at 3.5 m/s2?
The weight of the rock when it is accelerating downward at 3.5 m/s² can be calculated using the formula Weight = Mass * Acceleration due to gravity.
Explanation:The weight of an object is equal to its mass multiplied by the acceleration due to gravity. In this case, the weight of the rock when it is at rest is 138 N. Since the rock is accelerating downward at 3.5 m/s², the weight can be calculated using the formula:
Weight = Mass × Acceleration due to gravity
Let's assume the mass of the rock is 'm'. The acceleration due to gravity is approximately 9.8 m/s² on Earth. So, when the rock is accelerating downward at 3.5 m/s², its weight can be calculated as:
Weight = m × 3.5 m/s²

Who was the man that proposed the uncertainty principle
Final answer:
The uncertainty principle, a fundamental concept in quantum mechanics, was proposed by German physicist Werner Heisenberg, who was awarded the Nobel Prize in Physics in 1932.
Explanation:
The man who proposed the uncertainty principle was the German physicist Werner Heisenberg. Not only is Heisenberg renowned for his uncertainty principle, but he also received the Nobel Prize in Physics in 1932 for his fundamental contributions to quantum mechanics. The uncertainty principle is a fundamental concept in quantum mechanics which states that there is a limit to how precisely we can know both the position and momentum of a particle at the same time. This principle has further implications in variables such as energy and time, dictating that the product of uncertainties in these quantities is also subject to a minimum value determined by Planck's constant. The principle suggests that at a fundamental level, nature does not allow for the precise determination of certain pairs of physical properties simultaneously. While this principle may not be evident in everyday experiences due to the small scale of Planck's constant, it is essential for understanding the behavior of particles at the quantum level.
