Answer:
Magnitude of induced emf will be 87.5 volt
Direction of induced emf will be clockwise
Explanation:
We have given number of turns in the coil N = 50
Initial area
Time is given dt = 0.1 sec
Magnetic field B = 1.25 T
From Faraday's law of electromagnetic induction
n
So magnitude of induced emf is 87.5 volt
Direction of induced emf will be clockwise
Answer:
v = 7.9 m/s
Explanation:
length of the vine (L) = 20 m
initial angle with the vertical = 45 degrees
final angle with the vertical = 30 degrees
acceleration due to gravity (g) = 9.8 m/s^{2}
speed (v) =?
to solve this problem we can apply the equation below:
loss in potential energy = gain in kinetic energy
m x g x h = 1/2 x m x
v =
before we can apply the above we need to get our height
height = initial vertical height - final vertical height
height = (L - L cosθ2) - (L - L cosθ1)
height = (20 - 20cos45) - (20 - 20cos30) = 3.2 m
v =
v = 7.9 m/s

Answer:
1. He feels worse off.
2. His awareness of the grim situation.
Explanation:
Elie Weisel's memoir "Night" is about the persecution of the jews by the Germans during the worst genocide in world history. The events leading up to the Holocaust and the resulting after-effects through his personal experience provides one of the most prominent witness accounts of the crime.
When Weisel states that <em>"lying down wasn't an option</em>", he reveals how congested space was in the cabin. The <u>"lucky ones" were able to breathe in the fresh air from the window, while the rest have to be satisfied with wherever they are.
</u> This reveals his realization of the grim situation inside the over-packed cabin, where there is hardly any space to move.
And when he said that they <em>"never ate enough to satisfy our hunger"</em>, he presents the realization and understanding of the grim situation in the train's cabin where eating is not a luxury, but a necessity to stay alive. And for that, they know they have to <em>"economize, to save for tomorrow"</em> rather than just stay full once.
Answer:
(a). The horizontal and vertical components are and
(b). The horizontal and vertical components of the rocket's impact velocity is 150 m/s and 259.8 m/s.
Explanation:
Given that,
Angle = 60°
Speed = 300 m/s
(a). We need to draw the vector representing the rocket's impact and its components
Using given data
The components of rocket's impact
The horizontal component is
The vertical component is
(b). We need to calculate the horizontal and vertical components of the rocket's impact velocity
Using horizontal and vertical components
The horizontal component is
Put the value into the formula
The vertical component is
Put the value into the formula
Hence, (a). The horizontal and vertical components are and
(b). The horizontal and vertical components of the rocket's impact velocity is 150 m/s and 259.8 m/s.
