The equilibrant force of the two given forces is 14.14 N.
<h3 /><h3 /><h3>What is equilibrant force?</h3>- This is a single force that balances other given forces.
The given parameters:
- First force, F₁ = 10 N
- Second force, F₂ = 10 N
- Angle between the forces, θ = 90⁰
The equilibrant force of the two given forces is calculated as follows;
Thus, the equilibrant force of the two given forces is 14.14 N.

The amount of C-14 at time t is
where
N₀ = inital amount of C-14
t = years
K = 0.0001 = 10⁻⁴
When the skull was discovered, the amount of C-14 contained 43% of N₀.
Therefore
Answer:
The age of the skull s 8440 years (nearest integer)

The distance travelled in 5 seconds is 125 m
Explanation:
The motion of the skydiver is a free fall motion, since he is acted upon the force of gravity only. Therefore, it is a uniformly accelerated motion, with constant acceleration downward, and we can find the distance he travels by using the following suvat equation:
where
s is the distance travelled
u is the initial velocity
t is the time
a is the acceleration
In this problem, we have:
u = 0 (the skydiver jumps from rest)
(acceleration of gravity)
And substituting
t = 5.0 s
we find the distance travelled:
