Why do you think the temperature does not change much during a phase change?
11111nata11111 [884]

Answer:

It depends on where the temperature is dropping, in which body so to speak. Generally, the temperature adapts to the two bodies, for example if a hot piece of metal meets a cold one, the two will continue until they are at an equal temperature, an intermediate temperature.

A teenager of mass m1 = 72 kg pushes backward against the ground with his foot as he rides his skateboard. This exerts a horizon
Ray Of Light [21]

Answer:

The acceleration of the skateboard is -9.65 m/s².

Explanation:

Given that,

Mass of teenager = 72 kg

Force F_{foot}=11\ N

Mass of skateboard = 2.8 kg

Suppose, the determine the numerical value for the magnitude of the acceleration of skateboard

We need to calculate the acceleration of skateboard

Using balance equation

F-(m_{1}+m_{2})g=(m_{1}+m_{2})a

Put the value into the formula

11-(72+2.8)\times9.8=(72+2.8)\times a

a=\dfrac{11-(72+2.8)\times9.8}{(72+2.8)}

a=-9.65\ m/s^2

Hence, The acceleration of the skateboard is -9.65 m/s².

What conclusions can you make if a hockey goalie fails to block pucks shot in the upper right hand corner of the net
Lemur [1.5K]

Given what we know, we can confirm that this result from the goalie is a clear indicator of room for improvement in the reaction speed and visual coordination for this area of the net.

<h3>How can the goalie improve reaction speeds to this area?</h3>

The key for situations like this is simply repetition. The more the goalie is able to practice with shots in this area of the net, the more muscle memory they will build regarding reacting to these shots, and therefore less time will be needed to block them in the future.

Therefore, we can confirm that this result from the goalie is a clear indicator of room for improvement in the reaction speed and visual coordination for this area of the net.
