Based on what I see and the answered D But I don't know your results or your studies hope this helps you!!
Answer:
143.352 watt.
Explanation:
So, in the question above we are given the following parameters or data or information that is going to assist us in answering the question above efficiently. The parameters are:
"A 1.8 m wide by 1.0 m tall by 0.65m deep home freezer is insulated with 5.0cm thick Styrofoam insulation"
The inside temperature of the freezer = -20°C.
Thickness = 5.0cm = 5.0 × 10^-2 m.
Step one: Calculate the surface area of the freezer. That can be done by using the formula below:
Area = 2[ ( Length × breadth) + (breadth × height) + (length × height) ].
Area = 2[ (1.8 × 0.65) + (0.65 × 1.0) + (1.8 × 1.0)].
Area = 7.24 m^2.
Step two: Calculate the rate of heat transfer by using the formula below;
Rate of heat transfer =[ thermal conductivity × Area (T1 - T2) ]/ thickness.
Rate of heat transfer = 0.022 × 7.24(25+20)/5.0 × 10^-2 = 143.352 watt.

Answer:
Option (4)
Explanation:
Waves are generally caused by the wind that blows over the oceans. The waves formed by the wind are known as the wind driven waves. They are also known as the surface waves. When the wind blows over the surface of the ocean water, it creates a friction between them, as a result of which these surface waves are generated. This wind as well as the pressure differences below the ocean surface provides energy to the ocean waves. These waves are constantly moving in all the parts of oceans and are affected by the Coriolis force that results due to the rotation of the earth.
Hence, the correct answer is option (4).
Answer:
A
Explanation:
As you go deeper, the pressure increases because the water is going farther away from the air and atmosphere
