Answer:
option C
Explanation:
The correct answer is option C
Kinetic energy is the energy which is due to the motion of body.
Potential energy is the energy due to virtue of position of the object.
option A is not true because potential energy is due the position of the body
Option B should be the potential energy not kinetic energy.;
Option D is motion of individual molecule leads to kinetic energy not potential energy.
So, the correct answer is option is the covalent bonds of a sugar molecule is potential energy because of the position of bond.
(a) The work done by the force applied by the tractor is 79,968.47 J.
(b) The work done by the frictional force on the tractor is 55,977.93 J.
(c) The total work done by all the forces is 23,990.54 J.
<h3>
Work done by the applied force</h3>
The work done by the force applied by the tractor is calculated as follows;
W = Fd cosθ
W = (5000 x 20) x cos(36.9)
W = 79,968.47 J
<h3>Work done by frictional force</h3>
W = Ffd cosθ
W = (3500 x 20) x cos(36.9)
W = 55,977.93 J
<h3>Net work done by all the forces on the tractor</h3>
W(net) = work done by applied force - work done by friction force
W(net) = 79,968.47 J - 55,977.93 J
W(net) = 23,990.54 J
