Answer:

After studying the law of gravitational attraction, students constructed a model to illustrate the relationship between gravitational attraction (F) and distance. If the distance between two objects of equal mass is increased by 2, then the gravitational attraction (F) is 1/4F or F/4. How would this model, situation A, change if the mass of the spheres is doubled?

A)  A

B)  B

C)  C

D)  D

If you came here from usa test prep it is:

Actually A

But for the question given right now is D.

Answer:

New force, F' = F

Explanation:

Given that, two small balls, A and B, attract each other gravitationally with a force of magnitude F. It is given by :

F=G\dfrac{m_Am_B}{r^2}

If we now double both masses and the separation of the balls, the new force is given by :

F'=G\dfrac{2m_A\times 2m_B}{(2r)^2}

F' = F

So, the new force remains the same as previous one. Hence, the correct option is (d) "F"

The initial speed of a body is 3.28 m/s. What is its speed after 2.32 s if it accelerates
Helga [31]
Final velocity = initial velocity + acceleration * time

v = u + at

v = 3.28 + 2.32 * 2.08

v = 3.28 + 4.83

<u>v = 8.11 m/s</u>
