False because you have moved after you through the apple in the air
The answer is A because its asking how much of all 3 energies combined will it give off.
Answer:
α = 
Explanation:
Applying the equations of motion to determine angular acceleration of the unit,
The sum of moments about O is equal to the product of angular acceleration and moment of inertia
∑Mo = Io*α
Taking the anticlockwise direction as positive moment,
= ( -(1150) + (1400) ) * (0.5 / 2) + ( (475) - (650) ) * (0.3 / 2) - F = Io*α
= 36.5 - (2.5 N.m) =
*α
NOTE: moment of inertia of the pulleys in this instance = 
Hence, 33.75 =
* α
Solving, α = 
Answer:
Explanation:
Let the volume of air be V. at atmospheric pressure, that is 10⁵ Pa
At 20 m below surface pressure will be
atmospheric pressure + hdg
10⁵ + 20 x 9.8 x 1000 = 2.96 x 10⁵Pa
At this pressure volume V becomes V/ 2.96
This volume will last 1/2.96 times time that is 60/2.96 = 20.27 minutes.
