There is no work because there is no displacement
answer: 0
Answer:
100 N
Explanation:
From the question given above, the following data were obtained:
Mass (m) = 5 kg
Acceleration (a) = 20 m/s
Force (F) =?
Force is simply defined as the product of mass and acceleration. Mathematically, it can be expressed as:
Force (F) = mass (m) × acceleration (a)
F = ma
With the above formula, we can obtain the force need to move the object. This can be obtained as follow:
Mass (m) = 5 kg
Acceleration (a) = 20 m/s
Force (F) =?
F = ma
F = 5 × 20
F = 100 N
Therefore, a force of 100 N is needed to move the object.
Answer:
The temperature of well water be 288.07 K
Explanation:
We have given Heat in house 
Work done W = 900 J
Efficiency is given by 
Efficiency is also given by
, here
is lower temperature and
is higher temperature
So 


So the temperature of well water be 288.07 K
