Answer:
Part A 2.88 A, PART B 28.82 mA PART C 0.288 mA
Explanation:
We have given angular frequency
Voltage source has an amplitude of 24.5 V, So V= 24.5 volt
Part A
We have given inductance
So inductive reactance
So current
Part B
We have given inductance
So inductive reactance
So current
Part C
We have given inductance
So inductive reactance
So current
Answer:
1.1 x 10⁵m/s²
Explanation:
Given parameters:
Velocity = 452m/s
distance = 0.93m
Unknown:
Acceleration of the bullet = ?
Solution:
To solve this problem, we use one of the kinematics equation which is given below:
V² = U² + 2aS
V is the final velocity
U is the initial velocity = 0m/s
a is the unknown acceleration
S is the distance traveled
So;
452² = 0² + (2 x a x 0.93)
204304 = 1.86a
a = 1.1 x 10⁵m/s²

Answer:
Refraction
Explanation:
- Whenever there is a change in media through which light travels there is change in the speed of light due to which there is bending of light when there is change in the medium.
- When a ray of light passes from and optically denser medium to and optically rarer medium then it bends away from the normal to the interface and vice-versa.
As here the scuba driver is looking from an optically denser medium to an optically rarer medium the boy may appear nearer to the diver in position than is actually in the air.
Snell's law gives the relation between the angle of incidence and the angle of refraction as:
where
n = refractive index
i = angle of incidence
r = angle of refraction
