Potential energy is mass * gravity * height. (m*g*h).
350 = 17*9.8*h <--350 is its energy, 17kg is its mass, and 9.8 is gravity's acceleration on the object. We now just need to solve for h.
h = 350/(17 * 9.8) = 2.1 meters, which, when rounded to the nearest whole meter, is 2 meters.
The shelf is 2 meters high.
Answer:
All magnets have two poles: the North Pole and the South Pole.
Magnets attract ferromagnetic materials such as iron, nickel, and cobalt.
The magnetic force of a magnet is stronger at its poles than in the middle.
A freely suspended magnet always points in North-South direction.

Answer:
The material through which sound is travelling
Explanation:
Solid has compact molecules so sound waves can moove easily and fastly.
In case of liquid, it has relatively less inter- molecular space so, sound transfers slowly..
Hope you can generate meaning regarding spped of sound in gas...
MAKE ME BRAINLIST PLEASE...
