Answer:
Explanation:
Given
mass of crane 
distance moved 
Since it is moving with a constant velocity therefore net force on it is zero
Tension force=weight
T=mg
Work done by Tension T is
Work done by Gravity will be equal in magnitude but opposite in sign and can be obtained by work energy theorem which states that change in kinetic energy of object is equal to work done by all the forces
Answer:
the more particles packed together the faster it falls
Explanation:
the mass + the 1 constant g-force = the speed without adding air resistance
Answer:
You can change the momentum of an object by giving the object more force or less force.
Explanation:
Think about a ball. It is going slow, you push it and you give it more momentum.
Answer: 1. The field energy will increase
2. The energy increases, and the lines of force are denser
3. It points toward the field of earths magnetic poles
4. 1 and 2 only
5. 2, 4, 1, 3
