Well, the snow has a total weight G=mg=25,000 N. The work is L=Fd=Gh=1.5*25,000=37,500 J. The power is L/t, where t=1800 seconds. P=37,500/1800=20.833 W.
Answer: C
C. Place plastic around the metal wires, because electric charges
hardly move in plastic.
The pressure is
.
Answer: Option A
<u>Explanation:</u>
Pressure defines the force acting per single area. So depending upon the amount of force acting over a given area in the perpendicular direction of the object, the pressure acting on that area will vary.
So the pressure is directly proportionate to the applied force on a particular region and inversely proportionate into the areas of the region. Hence, the unit of pressure is considered as
or Pascal. Pressure can also be termed as the number of air molecules present in a specified closed region. Thus, for the present condition

Thus, by appling the given values in the above equation, we get,
= 
So the pressure is
.
Answer:
