Answer:
intinal speed should be 10
Explanation:
v = v0 + at
30 = v0 +10.2
then v0= 10
It increases, because the centripetal acceleration is inversely proportional to the radius of the curvature.
Hopr it helps :)
Answer:
in everyday use and in kinematic the speed of an object is the magnitude of the change of its position it is thus a scalar quantity
The correct answer for the question that is being presented above is this one:
Phi = BAsin(theta)
<span>1. Phi(i) = BA </span>
<span>2. Phi(f) = 0 </span>
3. EMF = N(phi(i)-phi(f))/deltat
Here are the follow-up questions:
<span>1. What is the total magnitude Phi_initial of the magnetic flux through the coil before it is rotated? </span>
<span>2. What is the magnitude Phi_final of the total magnetic flux through the coil after it is rotated? </span>
<span>3. What is the magnitude of the average emf induced in the coil?</span>
Answer:
Here is an image attached with similar questions.
The correct answer is D where acceleration is function of time.
Explanation:
The force acting on the object is constant.
There is no change in the application of forces.
And we know that Force is the product of acceleration and masses.
Newtons second law: 
Regarding mass we know that it can neither be created nor destroyed.
So in 
we have two constant terms, constant divided by constant will give the same result as 
There is no change in acceleration 
with respect to time 
.
So the most appropriate graph where time (t) is changing on 
but acceleration doesn't changes is D.
The graph will be similar to 
and will be horizontal to the .
Option D depicts the same.
