Answer:
Explanation:
a.
Given the permittivity constant to be 
,The capacitance of a 
of length, 
is given by the equation:
where 
is the radius of the outer cylinder and 
the radius of the inner cylinder.
The values are given as:
Substitute in our capacitance equation:
Hence the capacitance is 
b. The charge on the capacitance is related to the potential difference across it. The potential difference is expressed using the equation:
,
From a above, we already have our capacitance value,
We substitute 
in the pd equation:
Hence, the applied potential difference is 2.7344V
Because of the enormous expense of creating conditions aboard
a spacecraft in which astronauts can survive, and the huge extra
weight and expense of guaranteeing their safety.
Answer:
= 0.55 m
Explanation:
A standing wave is characterized by anti-nodes and nodes.
Antinodes are points on a standing wave at maximum amplitude, while nodes are points on the standing wave that are stationary and have zero amplitude.
The distance between two adjacent nodes or two adjacent anti-nodes is equivalent to half the wavelength.
Therefore, in this case the half wavelength is 27.5 cm.
Thus, wavelength = 27.5 × 2
= 55 cm
<u>= 0.55 m</u>
The motion of the racers might change from the start because the pressure goes up so all the racer wants is to speed up and win, so when the racer first starts he or she is calm because he's not driving yet and when he or she is on his/hers way to he finish line he/she just wants to win and gets under pressure so he speeds up even more and drifts.

Answer:
Part a)
Part b)
Part c)
Explanation:
Part a)
As we know that ball will reach at maximum height at
t = 3 s
now we will have
now we have
Now maximum height above ground is given as
Part b)
Height of the fence is given as
Part c)
As we know that its horizontal distance moved by the ball in 5.5 s is given as
now total time of flight is given as
so range is given as
so the distance from the fence is given as
