Answer:

-6.25\cdot 10^7 J

Explanation:

The gravitational potential at a point on the Earth surface is given by:

U=-\frac{GM}{R^2}

where

G=6.67×10^-11Nm^2kg^-2 is the gravitational constant

M=5.98×10^24kg is the Earth's mass

R=6.38×10^6 m is the Earth's radius

Substituting the numbers into the equation, we find

U=-\frac{(6.67\cdot 10^{-11})(5.98\cdot 10^{24})}{(6.38\cdot 10^6)}=-6.25\cdot 10^7 J

Direct current is the flow of an electric charge?
RUDIKE [14]
Direct current is the unidirectional flow of an electric charge.

The term 'unidirectional' in the statement means that direct current only moves in one direction. Direct current usually produced by things such as batteries, dynamos, and power supplies

What is the relationship between frequency and pitch?
Anton [14]
In general, pitch increases more rapidly than frequency for tones below 1000 Hz and less rapidly for tones above 1000 Hz. That is, for frequencies above 1000 Hz a greater change in frequency is needed to produce a corresponding change in pitch.

Two vectors of the same magnitude are added; one pointing east, one west. the magnitude of the resultant vector is:_________
alexandr1967 [171]

The net force is zero due to the direction.

We need to know about force resultant to solve this problem. The force resultant is the total net force applied to the object according to the direction. It can be written as

R = F1 + F2 + ... + Fn

where R is force resultant (net force)

From the question above, we know that

F1 = F2 = F N

Because the direction is the same, the force will be minus each other.

R = F1 - F2

R = F - F

R = 0 N

Hence, the net force is 0 N
