Answer:

6.45

Explanation:

Equation: E= Q/A(8.85*10^-12)

A= Q/E / (8.85*10^-12)

A= (4.98*10^-7)/8720 / (8.85*10^-12)

A=6.45

How does charging by conduction work?
anzhelika [568]

Answer:

During charging by conduction, both objects acquire the same type of charge. If a negative object is used to charge a neutral object, then both objects become charged negatively. ... In this case, electrons are transferred from the neutral object to the positively charged rod and the sphere becomes charged positively.

A tennis ball is thrown horizontally at a speed of 10 m/s from the top of a building 78.4 meters high. how long does it take the
cupoosta [38]
When it comes to horizontal projectiles, the formula for time is:

t =  \sqrt{ \frac{2dy}{g} }

Where:
dy = vertical distance or height
g = acceleration due to gravity
t = time

Based on the problem, we know that the height at which the tennis ball was thrown is 78.4 m and the acceleration due to gravity is a constant 9.8m/s2. All you need to do is input that into our equation:
t = \sqrt{ \frac{2dy}{g} }
t = \sqrt{ \frac{(2)(78.4m)}{9.8m/s^{2}} }
t = \sqrt{ \frac{156.8m}{9.8m/s^{2}} }
t = \sqrt{16s^{2}}
t = 4s

The time it would take is 4 seconds.
