Explanation:
Let 'F' be force acting perpendicularly, 'A' be the area and 'P' be the pressure exerted.
Then,
Pressure is directly proportional to the the force acting perpendicularly i.e.
P ∝ F ............. (i)
Pressure is inversely proportional to the area on which force acts i.e.
P ∝ 1/A ........... (ii)
Combining equations (i) and (ii),
P ∝ F/A
or, P = K × F/A [where K is a constant]
If F is 1N, A is 1m² and P is 1 N/m², then K is 1.
So, P = F/A proved...
Is there an all of the above box? these all seem right
Smart Metering is a technology encouraging end-use energy efficiency. Smart Meters can give consumers clear and comprehensive information about their energy consumption and, giving them better information, can help consumers to become more energy efficient.

Given: Weight W = 100 lbs convert to Kg = 45.36 Kg
Height h = 8 Ft convert to meter = 2.44 m
Time t =10 s
Required: Power output
Formula: P = W/t Work = Force x distance or Work = mgh
P = mgh/t
P = (45.36 Kg)(9.8 m/s²)(2.44 m)/10 s
P = 108.46 J/s
P = 0.15 Horsepower
