The answer should be A.
Mountain formations tend to take thousands of years to form, lava rolls relatively slowly, and lightning can travel faster than rockets.
Hope this helped!
Answer:
t = 0.04159 s
Explanation:
when a capacitor and resister are connected in series. charge on its plates decreases exponentially

where,
CHARGE q =15.0 C
INITIAL CHARGE q_0 = 30.0 uc
Resistor R = 20.0 F
capacitor C = 3.00

t = 0.04159 s
Using Kepler's third law which is defined as the square of the average distance is directly proportional to the cube of the period. It is expressed as P^2 = a^3, Given that the a = average distance is given, the period would be much easier to compute. P = sqrt(27^3) = 140
Hi there!
We can begin by deriving the equation for how long the ball takes to reach the bottom of the cliff.

There is NO initial vertical velocity, so:

Rearrange to solve for time:

Plug in the given height and acceleration due to gravity (g ≈ 9.8 m/s²)

Now, use the following for finding the HORIZONTAL distance using its horizontal velocity:
