Answer:
See answers below
Explanation:
a.
F = mg,
15.5 N = m(9.8 m/s²)
m = 1.58 kg
b.
Fnet = Applied force - resistance,
Fnet = 18 N - 4.30 N,
Fnet = 13.70 N
Fnet = ma
13.70 N = (1.58 kg)a
a = 8.67 m/s²
For the free body diagram, draw a box with an upward arrow labeled 15.5 N, a downward label labeled 15.5 N, a right label labeled 18 N, and a left label labeled 4.30 N.
Answer:
One transfer's and the other doesn't
Explanation:
Thermal energy doesn't transfer, but remain a part of the internal energy of the system.Heat transfer's it's energy, like when you sit in a cold chair, then becomes warm.That's because the energy was transferred from your body to the chair.
Answer:
The value is 
Explanation:
From the question we are told that
The electric flux is 
Generally the net charge is mathematically represented as
Here 
is the permetivity of free space with value
So
=>
No, we can not add the magnitudes of those two forces.
<h3>What is Gravitational Force?</h3>
An attractive force between masses is a gravitational force. According to Isaac Newton's second law, F = ma, a gravitational force generates an acceleration just like all other forces do. Remember that according to Newton's second law, a body will accelerate if there is a net force acting on it in an inertial frame of reference (a coordinate system travelling at a constant speed). According to Newton's Universal Law of Gravitation, when two bodies, such as the Earth and the Sun, are in close proximity to one another, an attractive force naturally attracts them. This attraction results in an acceleration of the two objects.

Answer:.
Coriolis effect and Temperature differences between the equator and the polar areas.
Explanation:
Global winds are created by both the spin of the Earth (Coriolis effect) and the differences in temperature between the equator and the polar areas. These winds are often grouped together as trade winds, easterlies, and westerlies.
