Answer:
Explanation:
Total heat = Work done = Force × distance
distance = 0.075 × 12 = 0.9 m
W = 45 × 0.9 = 40.5 joules
Specific heat of the human hand = 3.5 kj/kg = 3.5 j/g
Q = MCΔT
ΔT = (Q) ÷ (MC)
ΔT = 40.5 ÷ (3.5 × 1) = 11.57°C
Answer:
Well,
Explanation:
In this image, the thermal energy could be going both in an upwards and downwards direction. The chicken passes thermal energy to the salad under it. But at the same time, it is releasing smoke upwards, meaning it is also releasing thermal energy upwards.

Answer:
Explanation:
Given two objects are dropped simultaneously
Object A is 10 m higher than object B therefore
Distance covered by object A is given by
is given by

where y=displacement
u=initial velocity
a=acceleration
t=time

for object B

Subtract 1 and 2 we get

i.e. they will travel equal distance in equal time and distance between them remain 10 m until object B hits the ground
