Answer: option D. 4
Reasoning:
Assuming that the time elapsed between any two consecutive dots is the same, and that the second dot marks second 1, the column with 3 dots marks second 2, and the dot right most marks second 3, the motorcycle has positive acceleration after 4 seconds.
That is because:
1) from the first dot to the second dot: the velocity the lenght of the arrow that models the velocity decrases, which means that the acceleration is negative.
2) In the nex group of dots the length of the arrow remains equal, which means that the velocity is constant and the acceleration is 0.
3) For the last dot, the length of the arrow is greater, which means that the velocity increases, and so the acceleration is positive.
Electric field is defined as force per unit charge.
So it is given by
now we can find electric field by
So field strength is 0.75 N/C.
The mechanical advantage of a simple machine is the measure of its amplified force gain.
The mechanical advantage is defined as the force amplified by a machine to the force required to generate such output.
are the amplified force and applied force. We may also consider them as output and input force.
In the given question, the force given to the steering wheel is 50 N.
The output force produced by the steering wheel is 3750 N.
Hence the mechanical advantage will be-

Answer:
The magnitude of the torque on the loop due to the magnetic field is .
Explanation:
Given that,
Diameter = 10 cm
Current = 0.20 A
Magnetic field = 0.30 T
Unit vector
We need to calculate the torque on the loop
Using formula of torque
Where, N = number of turns
A = area
I = current
B = magnetic field
Put the value into the formula
Hence, The magnitude of the torque on the loop due to the magnetic field is .
Because north and east are positive directions and south is a negative direction, the answer is 50mi.
30mi north+50mi East-30mi south=50mi.
