Answer:
a.)How far from the building does the ball hit the ground?
72 m
b.)How long does it take to hit the ground?
6 s
c.)What is its speed when it hits the ground?
63.48 m/s
Explanation:
When an object is in free fall with no air resistance present or wind acting on it it only is under the influence of gravity. Gravity acts straight down and accelerates the object all the way to the ground. If there is air resistance or a wind force on the object it will have an acceleration that isn't 9.8 m/s^2
The magnitude of the magnetic force per unit length on the top wire is
2×10⁻⁵ N/m
<h3>How can we calculate the magnitude of the magnetic force per unit length on the top wire ?</h3>
To calculate the magnitude of the magnetic force per unit length on the top wire, we are using the formula
F= 
Here we are given,
= magnetic permeability
= 4
×10⁻⁷ H m⁻¹
If= 12 A
d= distance from each wire to point.
=0.12m
Now we put the known values in the above equation, we get
F=
Or, F = 
Or, F= 2×10⁻⁵ N/m.
From the above calculation, we can conclude that the magnitude of the magnetic force per unit length on the top wire is 2×10⁻⁵ N/m.

Answer:</h2>
The <u>interstellar medium</u> is the content of matter and energy that exists between stars within a galaxy.
In this sense, two components can be distinguished in the interstellar medium: dust particles and gas.
Dust represents 1% of the interstellar medium in mass, while the gas (consisting mainly of hydrogen and helium) represents 99% of the mass of the interstellar medium.
It should be noted that the interstellar matter is not uniformly distributed but is concentrated in molecular clouds.
Answer:
balanced force should be correct answer
