Answer:the force is needed to stretch it farther.
Explanation: the definition of force is push or pull so imagine stretching a rubber band your pulling the band which means you increase the force.
Answer:
So height will be 47.387 m
Explanation:
We have given gauge pressure 
Density of water 
Acceleration due to gravity 
We know that pressure is given as 


So height will be 47.387 m
Answer: It is D.
Explanation:
The compass needle pointed in the direction of the current's magnetic field.
Answer and Explanation: No, the explanation is not plausible. The puck sliding on the ice is an example of the <u>Principle</u> <u>of</u> <u>Conservation</u> <u>of</u> <u>Energy</u>, which can be enunciated as "total energy of a system is constant. It can be changed or transferred but the total is always the same".
When a player hit the pluck, it starts to move, gaining kinetic energy (K). As it goes up a ramp, kinetic energy decreases and potential energy (P) increases until it reaches its maximum. When potential energy is maximum, kinetic energy is zero and vice-versa.
So, at the beginning of the movement the puck only has kinetic energy. At the end, it gains potential energy until its maximum.
The representation is as followed:



As we noticed, mass of the object can be cancelled from the equation, making height be:

So, the height the puck reaches depends on velocity and acceleration due to gravity, not mass of the puck.
The longer the lever the longer the power
