an elastic material offers no resistance to forces that changes its shape

true or false

Answers

Answer 1

Answer:

Explanation:

FALSE

An elastic material like a rubber band or a spring definitely extends some resistance to its change.

However, in the case of non-elastic materials like hard plastic, the excess pressure results in the breakage of the material, whereas in the case of elastic materials, the excess pressure results in deformation of the shape.

Answer 2
false .
i think thats the correct answer

How will a skydiver's velocity change when a parachute first
opens?
a The speed will suddenly decrease.
b The direction of the velocity is now upward.
c The acceleration will stay the same.
d The speed will not change.

Answers

A, When the parachute opens, the air resistance increases. The skydiver slows down until a new, lower terminal velocity is reached.
A. When falling from a high speed, opening the parachute will cause the high speeds to slow down and cause you to fall slower hence why the parachute is needed to land safely

1. What part (or parts) of the system store potential energy?


2. What part( or parts) of this system have kinetic energy


3. If an object has kinetic energy what must it be done

Answers

Answer:

when you crank you make kinetic energy and then the kinetic energy makes potential energy.

all moving objects have kinetic energy

An object that has kinetic energy must be in motion

Potential energy is technically stored within matter, though a force must be applied to an object in order for it to store potential energy. However, while the energy itself is stored in the mass of the object, another force (gravitational or elastic) must be present to release the potential energy.

Kinetic energy is the energy an object has because of its motion. If we want to accelerate an object, then we must apply a force. Applying a force requires us to do work. After work has been done, energy has been transferred to the object, and the object will be moving with a new constant speed.
