Oil was created from the remains of sea animals and plants.
Answer=Oil
The tension in the swing's chain at the bottom of the swing is 178.35 N.
The given parameters:
- Mass of the girl, m = 27 kg
- Speed of the girl, v = 3 m/s
- Radius of the circle, r = 4 m
The tension in the swing's chain at the bottom of the swing is calculated as follows;
Thus, the tension in the swing's chain at the bottom of the swing is 178.35 N.

Explanation:
Work done by winch = kinetic energy of car
∫ T ds = ½ mv²
∫ 225s ds = ½ mv²
225/2 s² = ½ mv²
225 s² = mv²
v = 15s / √m
Given s = 10 m and m = 2500 kg:
v = 15 (10) / √2500
v = 3 m/s
Answer:
See description below
Explanation:
Given
Applied Force = 50N
Expected Appled Force = 350N
Difference = 350N - 50N
Difference = 300N
The frictional force will remain unchanged after the applied force gets to 300N.
At this point, the reason why the Net force is not zero (0) is because of the amount of force that is applied.
Also, since the frictional force is less than the applied force, the body will move in the right direction before it gets to 300 N the force of friction equals the applied force.
The second one since convection is the process by which heat is transferred from a solid surface to a non solid
