Explanation:
The amount of energy needed to raise the temperature
of water of mass
is
where is the specific heat capacity of water.
Putting in numbers into equation (1), we get:
which is the number of calories needed.
The vertical component of force exerted by the hi.nge on the beam will be,142.10N.
To find the answer, we need to know more about the tension.
<h3>How to find the vertical component of the force exerted by the hi.nge on the beam?</h3>- Let's draw the free body diagram of the system.
- To find the vertical component of the force exerted by the hi.nge on the beam, we have to balance the total vertical force to zero.
- To find the answer, we have to find the tension,
- Thus, the vertical component of the force exerted by the hi.nge on the beam will be,
Thus, we can conclude that, the vertical component of force exerted by the hi.nge on the beam will be,142.10N.
