The solution for this problem is computed by through this formula, F = kQq / d²Plugging in the given values above, we can now compute for the answer.
F = 8.98755e9N·m²/C² * -(7e-6C)² / (0.03m)² = -489N, the negative sign denotes attraction.
Force = mass * acceleration
Here is an equation for force, used to calculate force.
Look at it this way:-
Joules is used to measure force, while mass is measured by kg. Acceleration is measured by m/s/s (meters per second per second, or meters per second squared.)
joules = m/s/s * kg
Which makes everything fit in just right! :D
Power is energy per unit time. If he is powerful, it means he can spend more energy in short span of time, so option C ( i.e. <span>do more work in less time) is correct.</span>
Answer:
The centripetal force increases.
Explanation:
Centripetal force is given by 
; where 
.
Given these two equations, we can rewrite the formula for centripetal force as:
As shown, radius is in the denominator, thus, a smaller radius would lead to a larger centripetal force.
The masses are equal.
According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.
I hope that this helps you!
