Answer:
let's help eachother if u want?.
Explanation:
Alexis and Kym arrange to meet at the running track to train for an athletics carnival. They cycle to the track, leaving their homes at the same time. It takes Alexis 8 minutes to travel 2800 m from her home to the track. Kym takes 18 minutes,
after travelling a distance of 6.12 km.
Alexis thought she was faster, but Kym was not convinced. Who do you think was faster? Give reasons for your answer.
Answer:
The answer is letter B, absorb.
Explanation:
Heat travels through three different ways: radiation,conduction and convection.
Radiation- this happens when heat moves as energy waves (infrared waves) directly from its source to something.
Conduction- heat passes directly from one object to another through the touching of surfaces.
Convection- this occurs when warmer areas of a liquid or gas rise to cooler areas in the liquid or gas.
The transfer of heat in the situation above is an example of "thermal radiation." The campfire carries light energy through the fire. These consists of electromagnetic waves (most of these are infrared light). These waves (radiation) carry energy, which is then converted to heat once it hits another object that absorbs it. In the case above, once the hands absorbs the energy, it then warms up. This happened because the hands are placed <u><em>near the campfire.</em></u> Placing the hands near the campfire is important because air is a poor thermal conductor.
Thus, the answer above is letter B, absorb.

Answer:
gravitational potential energy of 10 kg mass is 122.625 J
Explanation:
Gravitational Potential energy gain is given as
here we know that
m = 10 kg
h = 1.25 m
now from above formula we have
So gravitational potential energy of 10 kg mass is 122.625 J
Answer:
The Answer is gonna be B.
Air warms and rises.
