Answer:
Charge, q = 1.402 C
Explanation:
Given that,
Current from lightning bolt, 
Time, t = 
Let q is the charge transferred in this event. We know that the total charge divided by time is called current. Mathematically, it is given by :



q = 1.402 C
So, 1.402 coulomb of charge is transferred in this event. Hence, this is the required solution.

Answer:
a. C = 0.5 m/s²
b. F = 35 Newton
Explanation:
Given the following data;
Radius, r = 200 m
Velocity, v = 10 m/s
Mass, m = 70 kg
a. To find the centripetal acceleration;
Mathematically, centripetal acceleration is given by the formula;
C = v²/r
Where:
C is the centripetal acceleration
v is the velocity
r is the radius
Substituting into the formula, we have;
C = 10²/200
C = 100/200
C = 0.5 m/s²
b. To find the force;
F = mv²/r
F = (70*10²)/200
F = (70 * 100)/200
F = 7000/200
F = 35 Newton
Answer:
Weightlessness is simply a sensation experienced by an individual when there are no external objects touching one's body and exerting a push or pull upon it.
