Answer:
length of one side of the coil is 0.1083 m
Explanation:
given data
no of turn = 269
coil rotates = 113 rad/s
magnetic field = 0.222-T
peak output = 79.2 V
solution
we will apply here formula for maximum emf induced in a coil that is
εo = N × A × B × ω ........................1
and here Area A = l²
so
l = 
put here value of A from equation 1
I = 
put here value and we will get
l = 
l = 0.1083 m
What's your question? is it seprete questions
Answer:
OKAy okay here Please laugh kinda cringe but...
Explanation:
Two hunters are out in the woods when one of them collapses. He’s not breathing and his eyes are glazed. The other guy whips out his cell phone and calls 911.
“I think my friend is dead!” he yells. “What can I do?”
The operator says, “Calm down. First, let’s make sure he’s dead.”
There’s a silence, then a shot. Back on the phone, the guy says, “OK, now what?”
Answer:
Thermal and kinetic.
Explanation:
Thermal energy is the energy generated by heat. Kinetic energy is the movement of particles in a substance which is responsible for the heat increase.
Answer:
The temperature of the brakes is 29.38°C.
Explanation:
Given that,
Mass of car = 750 kg
Speed = 23 m/s
Mass of iron = 15 kg
We need to calculate the kinetic energy of car
Using formula of kinetic energy
We need to calculate the temperature of the brakes
Using formula of energy
Put the value into the formula
Hence, The temperature of the brakes is 29.38°C.
