Answer:
P = 113.4 N
Explanation:
We know that if it is on the Moon it has another gravity. Therefore, it is known through the International System that the gravity of the Moon is 1.62 m/s², so..
Data:
- m = 70 kg
- g = 1.62 m/s²
- P = ?
Use formula:
Replace and solve:
The man's weight is <u>113.4 Newtons.</u>

They are called mechanical waves
Answer:
is the distance from the target before which the pilot must release the canister.
Explanation:
Given:
- height of the plane,
- horizontal speed of plane,
<u>Time taken by the canister to hit the ground:</u>
using equation of motion
where:
initial vertical velocity of the canister = 0 (since the the object is dropped from a horizontally moving plane)
time taken to hit the ground
<u>Now the horizontal distance travelled by the canister after dropping:</u>
is the distance from the target before which the pilot must release the canister.
The power is defined as the energy used divided by the time :
where E is the energy and t the time.
In our problem, the energy used is E=0.45 kWh=450 Wh while the time is t=6 h, so the power used by the fan is
