Answer:
1.Magnetic Force - Used in cranes to separate metal junk from junkyards.
2.Frictional Force- Helps us to walk.
Set-up: Set initial speed at 15 m/s. Set the height of the cannon to 0 meters. Be sure that air resistance is NOT checked.
B. 2. Our independent variable in this simulation will be the launch angle. Keeping the speed at 15 m/s, vary the launch angle as indicated in the table below. Drag the crosshairs marked with time and range to the spot where the object landed. Then drag the crosshairs to the top of the parabola to find max height. Fill in the table below with the values.

Why does the law of conservation of energy limits the efficiency of any machine.
Answer: Because machines cannot create new energy themselves, they merely change its direction, its form, the amount applied, or the distance it is applied over. Therefore, although it may seem like machines make things easier, in reality they just convert one form of energy into another, and cannot multiply energy or work.
Explanation:
Which best explains why the shape of a liquid can change? (1 point) a The particles have just enough energy to move past each other. b The particles are charged. c The particles move at very high speeds at all times. d The particles are highly compressible.
Answer:
The particles have just enough energy to move past each other.
Answer:
A
Explanation:
Solid's particles cannot move past each other and are stuck in place. Liquid's particles are able to slightly move past each other. And gas's particles move freely.
Hope this helps!
