Answer:
The answer is
<h2>5 m/s²</h2>Explanation:
The acceleration of an object given it's mass and it's net force can be found by using the formula
From the question
force = 60 N
mass = 12 kg
So we have
We have the final answer as
<h3>5 m/s²</h3>Hope this helps you
Answer:
(a) Utilization
Explanation:
Thermodynamic energy are:
<h2>(1) Kinetic energy:</h2>Kinetic energy is that type of energy of a body which occurs due to the motion of body. Kinetic energy is always positive. In a bound system, the system remains bound as long as the kinetic energy is less than the potential energy due to the interaction of the body.
Potential energy is defined as the energy in which the energy is possessed by a body or a system for doing some work, by virtue of its position above the ground level.
Therefore,
Potential energy = PE = mgh
This potential energy is a result of gravity pulling downwards. The gravitational constant, g, is the acceleration of an object due to gravity. This acceleration is about 9.8 m s⁻².
<h2>(3) Stored energy:</h2>Stored energy is a Potential energy.
Hence, the only energy which is not a thermodynamic energy is option (a) Utilization energy.
