Magnetic force:Computer hard drives use magnetism to store the data on a rotating disk. More complex applications include: televisions, radios, microwave ovens, telephone systems, and computers. ... Frictional force:Quite often uses of friction can be seen from how things would be without friction.
Explanation:
Both slinky waves and seismic waves are mechanical waves. Mechanical waves requires a medium to travel. These are of two types i.e. transverse wave and longitudinal waves.
Slinky wave is transverse in nature. The medium particle move to and fro during wave propagation.
Seismic waves are longitudinal in nature. These waves moves in the form of compression and rarefaction. Seismic waves are of two types i.e. P waves and S waves.
Hence, we have concluded that both waves are mechanical waves.
Answer:
A flame always point upwards because the flame's gas is hotter than the surrounding air and, like you said, a hot gas is always lighter or less dense than a cold gas.
Explanation:
Answer: you'll see cyan color on the screen
Explanation:
Saturating the red cone causes them to stop functioning, hence you can't perceive the red part of white light. White light is made up of three main colors which are blue, red and green. When one can no longer perceive the red part of light, one is left with the grean and blue part. The green and blue part of light will superimpose to give a cyan color.
Answer:When we toss a ball into the air, its height increases and thus, its potential energy increases as well.
Explanation:Because when a ball is tossed up, its potential energy increases, reaches a maximum height and then starts decreasing as the ball falls back to the ground.
