The Car Will Cause Some Kind Of Wind Wave And Hit The Person's Body But Its Not Harmful And You Will Hear The Loud Noise Passing By
Answer:
Induced current, I = 18.88 A
Explanation:
It is given that,
Number of turns, N = 78
Radius of the circular coil, r = 34 cm = 0.34 m
Magnetic field changes from 2.4 T to 0.4 T in 2 s.
Resistance of the coil, R = 1.5 ohms
We need to find the magnitude of the induced current in the coil. The induced emf is given by :
Where
is the rate of change of magnetic flux,
And 
Using Ohm's law, 
Induced current, 
I = 18.88 A
So, the magnitude of the induced current in the coil is 18.88 A. Hence, this is the required solution.
Answer:
YES
Explanation:
Asexual means the plant is identical to the parent
Answer:
55 mA
Explanation:
Ohm's law states:
V = IR
where V is voltage, I is current, and R is resistance.
220 V = I (4000 Ω)
I = 0.055 A
I = 55 mA
24. 02 N force of friction acting on the box.
<h3 /><h3>What is force?</h3>
A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
Force = mass. acceleration
Force = (2.2).(3.2)
Force = 7.04 N
Total force applied is 31.06 N
Frictional force = 31.06 - 7.04
Frictional force = 24. 02 N
24. 02 N force of friction acting on the box.
