Answer:
DU = 20 Joules
Explanation:
Given the following data;
Heat absorbed, Q = 60J
Workdone, W = 40J
To find the internal energy;
We would use first law of thermodynamics given by the formula;
Change in internal energy (DU) = Q - W
where;
U is internal energy.
Q is the heat absorbed.
W is the work done.
Substituting into the equation, we have;
DU = 60 - 40
DU = 20 Joules
Chemical bonds. These bonds form as a result of the sharing or exchange of electrons between the atoms

The true statement according to Newton's laws of motion is; "there is no net force on the block during the 2nd second as zero net force keeps the motion constant."
According to the Newton first law of motion, an object will continue in its state of rest or uniform motion unless it is acted upon by a net force. The action of a net force leads to an acceleration.
In the 2nd second of the journey, there is no net force on the block hence the block continues to move at constant velocity.
