Answer: Option 1: 1 J
Explanation:
Average mass of an apple is between 60 g to 200 g It is not greater than this.
We can take an average mass, m =130 g
This average mass approximation would not affect the final answer.
The work done in lifting any object is given by:
W = m g h
Where, m is the mass of the object, g is the acceleration due to gravity and h is the height to which the object is lifted.
It is given that, h = 1 m
g = 9.8 m/s²
m = 130 g = 0.13 kg
⇒W =0.13 kg×9.8 m/s²×1 m = 1.3 J ≈ 1 J
Thus, the work done in lifting an apple one meter near Earth’s surface is approximately 1 J

Then the maximum height decreases to 16 x 0.81
And the distance traveled is twice the distance traveled.
If we make a pattern, this forms a geometric progression in which the common ratio is 0.81 and the first term is 16.
The sum of this series: a / (1 - r)
= 16 ( 1 - 0.81)
= 84 feet
This is the upward height, and the ball returns every time so:
Total distance = 84 x 2
= 168 feet

The so-called 'terrestrial planets' are Mercury, Venus, Earth, and Mars.
The asteroid belt separates them from the 4 gas-giant planets, in a wide
gap where there should be another planet but there isn't.
Among the terrestrial planets as a group:
A). Water
No. Only earth has water (now).
B). Iron core
Yes. Most probably all.
C). Rocky crust
Yes. All.
D). Thin atmosphere.
E). Dense Atmosphere.
No.
Only Venus has a dense one.
Mercury probably has none.
Earth has the Goldilocks atmosphere.
F). Relatively high density.
Yes.
True of all the terrestrial planets.
Earth is the most dense of all the planets.
