Answer:
The flux through the surface of the cube is
Solution:
As per the question:
Edge of the cube, a = 8.0 cm =
Volume Charge density,
Now,
To calculate the electric flux:
(1)
where
= electric flux
= permittivity of free space
Volume Charge density for the given case is given by the formula:
(2)
Volume of cube,
Thus
Thus from eqn (2), the total charge is given by:
Now, substitute the value of 'q' in eqn (1):
Answer:
Explanation:
Wavelength of sound produced is given as
now we know that the frequency of sound is given as
frequency of the other sound is given as
now the beat frequency is given as the difference of the frequency
Kinetic energy formula:
E k = m v²/2
If the velocity is doubled:
E k 1 = m ( 2 v )² / 2 = 4 m v² / 2 = 4 E k
Answer: kinetic energy is quadrupled.
Answer:
<h2>2500 N</h2>
Explanation:
The weight of the object can be found by using the formula
w is the workdone
d is the distance
From the question we have
We have the final answer as
<h3>2500 N</h3>
