That's an example of heat transfer by radiation.
Answer:
14.56 N
Explanation:
According to Newton's second law of motion,
The force acting on a body is equal to the product of its mass and acceleration acting on it.
Weight of a body on a planet is equal to the force due to gravity of the planet. So, weight is the product of mass of body and acceleration due to gravity of the planet.
Here, acceleration due to gravity on planet A is m/s² and mass of an object on it is kg.
So, weight of an object, , on planet A is given as,
I got the 1.0g of coal producves 35,000 joules which is also 8.36 kcals
Answer:
The power is 29.76 J.
Explanation:
Given that,
Force = 22 N
Radius = 0.28 m
Time = 1.3 s
The force is always applied parallel to the motion of the handle.
So, angle is 0°.
We need to calculate the work done
Using formula of work done
Where, F = force
d = distance
Put the value into the formula
We need to calculate the power
Using formula of power
Hence, The power is 29.76 J.
