Answer:
C?
Explanation:
My best guess would be C as it's the only answer that gives a reason behind the statement.
I think the right answer would be objects pull because gravitational pull is when an object with more mass than an other object would pull the small mass object
Answer:
part A ⇒ u = 1.28 m
part B ⇒v = 0.43 m
Explanation:
for u is the distance to the object from the mirror and v is the distance from the mirror to the image.
Part A:
the mirror equation is given by:
1/f = 1/v + 1/u
but we told that, v = 1/3u:
1/f = 3/v + 1/u = 4/u
1/f = 4/u
f = u/4
u = 4f
= 4×(32×10^-2)
= 1.28 m
Therefore the distance from the mirror to the object is 1.28 m.
part B:
v = 1/3×u = 1/3×(1.28) = 0.43 m

Answer:
Explanation:
Given:
- mass of the object,
- weight of the object on planet x,
- radius of the planet,
- radial distance between the planet and the object,
<u>Now free fall acceleration on planet X:</u>
irrespective of the height.
