Answer:
c)
Explanation:
Coulomb's law says that the force exerted between two charges is inversely proportional to the square of distance between them, and is given by the expression:
where k is a proportionality constant with the value
In this case , so we have:
Solving the equation for q, we have:
Replacing the given values:
Answer:
2874.33 m/s²
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
g = Acceleration due to gravity = 9.81 m/s²
Now H-h = 0.588 - 0.002 = 0.586 m
The final velocity will be the initial velocity
Acceleration of the frog is 2874.33 m/s²
