The answer is C. Hope it helps
Answer:
8 newtons
Explanation:
Balanced forces have an equal amount of newtons. 5+3=8, so the other team will need 8 newtons.
<span>When an atom undergoes decay its nucleus becomes unstable because it does not have a balance of neurons and protons. This means the atoms try to find a confirmation in which it is stable. In doing so, it is possible that the atom changes its element, and it frees a huge amount of energy in order to balance itself. This is the base of radioactivity.</span>
Heat transfer is limited to conduction and radiation only in anomalous expansion of water simply because of the temperature at which the expansion occurs and density
<h3>What is anomalous expansion of water?</h3>
Anomalous expansion of water is a property of water in which water expands instead of contracting.
- Anomalous expansion of water makes water less dense.
- The major effect of this anomalous expansion it will still remain less dense and at the surface of water.
- Interestingly, this expansion occurs when it is cooled from 4°C to 0°C.

(a) 907.5 N/m
The force applied to the spring is equal to the weight of the object suspended on it, so:

The spring obeys Hook's law:

where k is the spring constant and
is the stretching of the spring. Since we know
, we can re-arrange the equation to find the spring constant:

(b) 1.45 cm
In this second case, the force applied to the spring will be different, since the weight of the new object is different:

So, by applying Hook's law again, we can find the new stretching of the spring (using the value of the spring constant that we found in the previous part):

(c) 3.5 J
The amount of work that must be done to stretch the string by a distance
is equal to the elastic potential energy stored by the spring, given by:

Substituting k=907.5 N/m and
, we find the amount of work that must be done:
