The equation for mechanical work done is:
Work done = force / distance
Work done = force + distance2
Work done = distance x force2
Work done = force x distance

A
B
C
D
Specific heat capacity is defined as the amount of (a) required to heat up 1kg of a substance by 1 degree celsius
For a patio heater like the one shown, why is it important that the hood at the top is made from a shiny silver metal?
To absorb the IR radiation better
To absorb and emit the IR radiation better
To reflect the IR radiation back down at the people below
