Answer:
option D
Explanation:
given,
coefficient of friction between wall and tire = µ
speed of motorcycle = s
friction force = f = μ N
where normal force will be equal to centripetal force

for motorcycle to not to slip weight should equal to the centripetal force
now,


where "rg" is constant


Hence, the correct answer is option D
The potential difference between the plates will be 1552 Volts.
<h3>What is a potential difference?</h3>
Voltage, or the difference in electric potential between two points, is defined as the amount of labor per unit of charge needed to move a test charge between the two points.
Given that a 3.7-f capacitor that stores sufficient energy to operate a 75.0-w
The potential difference will be calculated by the formula below:-
Q = I t
Where I = charge / time
Q = V * C
V C = I t
V = I t / C
V = 75 C/s x 60 sec / 2.9 faraday
V = 1552 Volts

Answer:
(a) 
(b) 
Explanation:
The average power is defined as the amount of work done during a time interval:

According to work-energy theorem, the work done is equal to the change in kinetic energy. So, we have:

Recall that the weight is given by:

The car accelerates uniformly from rest (
). Replacing (3) in (2), we have:

(a) Finally, we replace this in (1):

(b)

Answer:

Explanation:
<u>Accelerated Motion</u>
It occurs when an object changes its speed over time. If the changes in speed are uniform, then the acceleration is constant, positive if the speed increases, negative if the speed decreases.
The acceleration is calculated as follows:

The aeroplane starts with a speed of vo=62 m/s and reaches a speed of vf=6 m/s in t=35 s.
The acceleration is:
