Answer:

Explanation:
Let the charge on the large droplet be denoted as Q.
When the radius of the droplet is R, the electric potential for the larger droplet can be expressed as:

If it splits into n identical droplets, let the charge of each be "q" and their radius be "r".
Applying volume conservation gives us:


Now, the potential for the smaller droplets is given as:




1 hour = 3,600 seconds
1 km = 1,000 meters
75 km/hour = (75,000/3,600) m/s = 20-5/6 m/s
The mean speed during the deceleration is
(1/2)(20-5/6 + 0) = 10-5/12 m/s.
Traveling at this average speed for 21 seconds,
the bus covers
(10-5/12) × (21) = 218.75 meters.
Answer:
12.1 seconds
Explanation:
t = time duration
u = initial speed
v = final speed = 0
s = distance = 120 m
a = lunar gravity acceleration = 1.67 m/s²
Motion equation


The rock takes 12.1 seconds to reach the bottom of the crater.
The formula for range is:

Given values are:

where θ equals 14.1 degrees

Using the equation above,

The calculated range is 66.7 meters.
Therefore, the range is approximately 66.1 meters.
A bathroom scale operates under gravitational influence. Typically, a reading is captured when your body applies force onto the scale. Yet in this scenario, as both you and the scale move downwards, your body ceases to press against the scale. Consequently, the result is:
