Not sure about the answer
Answer:
Yes, you would be safe without skidding off
Explanation:
In this situation the sum of forces on the car would be:
And the maximum friction force is:
Since the required force is smaller than the maximum force, we can say it will not skid off
Example:
<span>Suppose that a ball has an initial velocity v0 that has magnitude 20.0 m/s and is directed 60.0 degrees above the negative x axis.
Then, the x-component is,
20.0 * cos(-60) = 20.0 * (1/2) = 10.0</span> m/s
Answer:
A) 2
Explanation:
Given;
magnetic field of the coil, B = 1.6 T
frequency of the coil, f = 75 Hz
maximum emf developed in the coil, E = 56.9 V
area of the coil, A = 0.15 m x 0.25 m = 0.0375 m²
The maximum emf in the coil is given by;
E = NBAω
Where;
N is the number of turns
ω is the angular velocity = 2πf = 2 x 3.142 x 75 = 471.3 rad/s
N = E / BAω
N = 56.9 / (1.6 x 0.0375 x 471.3)
N = 2 turns
Therefore, the value of N is 2
A) 2
