Answer: Option (a) is the correct answer.
Explanation:
Resources which are created by human beings are known as man-made resources.
For example, glass, rayon, nylon etc are all man-made resources.

Answer:
Production of electricity from nuclear energy is a lot more expensive than production of energy from fossil fuels
Explanation:
uranium is one of the rarest elements on earth, its more expensive than gas and oil, and it makes the same if not more pollution.
Here, F = m * a
F = m * v/t
Here, m = 81 Kg
v = 22 m/s
t = 1,4 s
Substitute their values,
F = 81 * 22/1.4
F = 81 * 15.71
F = 1273 N
So, Closest value from your options is 1300 N
In short, Your Answer would be Option B
Hope this helps!
Answer:
The correct option is C
Explanation:
From the question we are told that
The distance between axles of the car is 
The position of the car's center of mass is 
Now we can evaluate the distance of the center of mass to the rear axle as follows
substituting values
assuming the car is at equilibrium, taking moment about the center of mass
=> 
=> 
substituting values
Note [
is the front axle weight and
is the rear axle weight ]
