In Newton's cannonball experiment, if the velocity is equal to the orbital velocity then the cannonball will stay in Orbit.
Newtons cannonball experiment stated that the distance that a cannonball will travel, before being drawn into the Earth by the forces of gravity, is dependent on the initial velocity.
Therefore, if the cannonball is launched at a velocity that matches the orbital velocity, then it will not be able to be drawn in by gravity due to the Earth moving away from the cannonball at the same speed at which the cannonball itself is falling.
This means that the cannonball will continue to fall without reaching the Earth, therefore staying in orbit, much like that of the moon or planets around the sun.

A concave mirror is used in the design of solar furnaces because they converge the parallel sunrays at a point. This helps to increase the temperature of the furnace.
Answer:
PART A)
L = 97.4 dB
PART B)
PART C)
L = 67.9 dB
Explanation:
PART A)
level of sound is given as
now we have
PART B)
Since source is a spherical source
so here the intensity of sound is inversely depends on the square of the distance from the source
PART C)
level of sound is given as
now we have
<u>Answer:</u> The charge on each plates is 
.
<u>Explanation:</u>
The magnitude of charge that flows through the plates is directly dependent on the capacitance and the voltage flowing through the plates.
Mathematically,
where,
Q = charge flowing = ? C
C = capacitance = 
(Conversion Factor: 
)
V = Voltage across the plates = 12 V
Putting values in above equation, we get:
Hence, the charge on each plates is .
