SOLUTION:
Total amount of fruit = Total amount of apples + Total amount of pears + Total amount of oranges
Total amount of fruit = 15 / 4 + 29 / 4 + 81 / 8
Total amount of fruit = 30 / 8 + 58 / 8 + 81 / 8
Total amount of fruit = 169 / 8
Total amount of fruit = 21.125 kg
ANSWER:
Therefore, the chief bought 21.125 kg of fruit all together.

Explanation:
Artificial gravity can be created using a centripetal force. A centripetal force directed towards the center of the turn is required for any object to move in a circular path. In the context of a rotating space station it is the normal force provided by the spacecraft's hull that acts as centripetal force.
Hope it helps.
Answer:
v=10 m/s
Explanation:
Given that,
Speed of a drone is 8 m/s due East with respects to the wind
Speed of a drone 6 m/s due North with respect to the ground.
We need to find the speed of the drone with respect to the ground. Let v is the speed. It is given by the resultant of two speeds.
So, the speed of the drone with respect to the ground is 10 m/s.
<u>Answer</u>
The distance must be one-third the original distance.
<u>Explanation</u>
Gravitational force is the force of attraction between two bodies of given masses. It is calculated by the formula;
Gravitational force = Gm₁m₂/r²
This means, for the gravitational force to remain unchanged, both numerator and denominator has to change by equal value.
The numerator changed by (1/3×1/3 = 1/9).
So, r² must change by the same value which is 1/9.
If r² ⇒ 1/9, then
r ⇒ √1/9
⇒ 1/3
So, this means, for the gravitational force to remain as 200, The distance must be one-third the original distance.
