This is specific latent heat of fusion.
This is the heat needed to turn 1 kg of solid into a liquid at its melting point. When a substance changes its state from solid to liquid form or from liquid to gas , heat energy is needed. This energy is used not to heat the substance but to separate the molecules from each other.
This energy is called latent heat energy. While a liquid is boiling and while a solid is melting, there is no temperature change. The temperature only changes when the change of state is complete.
Answer:
Low pressure
Explanation:
Take two nearby points at the junction of both the tube, let point 1 be in the air tube while point 2 be in the paint tube.
According to Bernoulli's principle, the air at point 1 is moving with some speed which causes the pressure drop inside tube 1, while at point 2 there is no velocity, so there is no pressure drop at that point. In fact, the pressure at point 2 approximately equals the atmospheric pressure.
As both the points are taken is nearby at the junction, to the pressure drop in the flow air pipe causes the suction of fluid from the relatively high-pressure tube (paint tube).
Hence, this rush of air creates low pressure, which sucks the paint up the tube and into the stream of air.
Answer:Sometime decreases and sometime increases.
Explanation:
Given
Projectile is launched at
so horizontal velocity=ucos35
vertical velocity=usin35
since gravity acts in the vertical direction, therefore, it affects only the vertical component of the projectile.
So Vertical velocity first decrease up to maximum height and then starts to increase.
The above answer is correct!
Energy is carried to Earth in a form of photons or simple radiation.
