Answer:
Explanation:
To give a solution to the exercise, it is necessary to consider the concepts related to magnetic flux and Faraday's law of induction. Faraday's law states that the voltage induced in a closed circuit is directly proportional to the speed with which the magnetic flux that crosses any surface with the circuit as an edge changes over time.
It is represented under the equation,
Where,
is the induced electromotive force
N = Number of loops
= Time
= Magnetic Flux
For definition the change in magnetic flux is:
Where,
B= Magnetic field
Substituting at the first equation we have
Our values are given by,
N = 1 turn
r = 1.6mm
Replacing,
<em>Therefore the magnitud of the induced emf around a horizontal circle of tissue is </em>
Answer:
1/6 m/s^2 ( about 1/6th gravity of Earth ( 9.81 m/s^2)
Explanation:
Displacement = yo + vo t - 1/2 a t^2
- 3.2 = 0 + 0 - 1/2 a(2.0)^2
- 3.2 = -2a
a = 3.2 / 2 = 1.6 m/s^2
Answer:All balls have same velocity
Explanation:
Ball A
horizontal velocity
vertical velocity
let h be the height of building
Vertical velocity acquired by Ball A
Velocity just before hitting ground=
Ball B
launched with velocity u at angle of 45 above horizontal
horizontal velocity will remain same as there is no acceleration in that direction
vertical velocity just before hitting the floor
Final velocity before hitting ground
Ball C
horizontal velocity will remain same as there is no acceleration in that direction
vertical velocity just before hitting the floor
Final velocity before hitting ground
Thus all three balls will have same final velocity.
Answer:
95 feet
Explanation:
We have given that 4 boards are of so total number of feet of 4 boards =
Two board are of so total number of feet of two board
And two boards are of so total feet
So total height of all boards = 58.5+23.5+13=95 feet
Answer:
The answer is option C.
Wind energy to kinetic energy to electric energy
Hope this helps
