Answer:
(a) The maximum conduction current is A
(b) Value of V
(c) Maximum value of
Explanation:
Given:
Radius of circular plates m
Separation between plates m
Frequency Hz
Maximum displacement current A
(a)
Displacement current is equal to the conduction current so we write,
A
(b)
From the formula of displacement current,
Where , peak value of emf,
V
(c)
From another formula of displacement current,
Where change in flux
Therefore, the maximum conduction current is A and value of
V and maximum value of
Answer:
Explanation:
Given
Required
Determine the velocity when t = 8
This type of velocity is referred to as an instantaneous velocity.
In this case, it is calculated using
Given that s(t) models the distance;
s(8) = distance at 8 seconds
So;
Option B answers the question
Answer:
The ray's angle with respect to the face of the crystal is 71.6°
Explanation:
Given that,
Incidence angle = 27°
We need to calculate the angle of refraction
Using Snell's law
Put the value into the formula
We need to calculate the ray's angle with respect to the face of the crystal
Using formula of refraction
Put the value into the formula
Hence, The ray's angle with respect to the face of the crystal is 71.6°
True, the sun keeps many things on Earth but not all living things rely on it!
F=ma
=> 20=10m so m=2
Then the force is doubled 20.2=40
F'=ma'
m does not change so 40=2.a'
a'=20 which is option b.
