<h2>Question</h2>
why freezer is made in the upper part of refrigrator
<h2>✒ Answer</h2>
the cold air produced from it is denser than the warmer air in the bottom
<h3>Explaination</h3>
Freezer is normally provided at the top of the refrigerator, because density of the cold air is high compared to the hot air. In a refrigerator the air contacts with the cooling coil and gets cooling.Because of the high density the cold air gets down and the warm air/hot air moves upward and gets cooling from the cooling coil/evaporator coil. This process is repeated. If the Freezer is provided at the bottom place of the refrigerator, the cold air can't to move full area of the refrigerator. So the freezer is normally provided at the top at the refrigerator
Answer:
5ms^-2
Explanation:
F = 20N, m = 4.0kg, a = ?
Using the formula for Force
F = ma
Then making acceleration the subject of the formula
a = F/m
a = 20N/4.0kg
a = 5ms^-2
Answer:
Ok so there are many ways to go at this.
you can get a zip lock bag and put a bunch of plastic around the egg inside the bag. (image down below)
Just anything to slow down the descent speed.
Cushion the egg so that something other than the egg itself absorbs the impact of landing.
Explanation:
<u>Answer;</u>
<em>The moving car transfers kinetic energy to the parked car. </em>
<u>Explanation;</u>
- Energy is the ability of work to be done. It is measured in joules. The energy in an object depends on whether an object is in motion or at rest.
- Kinetic energy is the energy possessed by a body in motion. Calculated by 1/2mv², where m is the mass of the body and v is the velocity of the body in motion. Therefore, the moving car possess kinetic energy.
- When a body is at rest it posses potential energy. Thus, the parked car possessed kinetic energy which changed when it was hit by the moving car as the kinetic energy of the moving car was transferred to the parked car.
