Answer: t=4.6*R*L
Explanation: In order to explain this problem we have to take into account the expression for the current in a RL electric circuit, which is given by:
where If is the final current for RL circuit If (emf/R)
Considering the final current is getting when I(t) = 0.99*If we have:
reoganising the terms we have:
e^(-t/R*L)=(1-0.99)
ln(e^(-t/R*L))=ln(0.01)
then t=4.6*R*L
As per the question the length of the string is given as 2 metre.
A ball is attached to the string.
The ball is taken above the head and the ball starts swinging.
Swinging motion of a body may be oscillatory or circular. Here the motion is circular.
Here the length of the string will be considered as the radius of the circular path. we are asked to calculate the distance traveled by the ball in each circular rotation.
As the motion is circular, the path covered by the ball in each rotation will be equal to the circumference of the circle.
The circumference of the circle is given as
where C is the circumference.
hence C=2×3.14×2 metre
=.12.56 metre.
Hence distance covered by the ball in each circular rotation is 12.56 metre.
Here the displacement is zero. one should not be confused between distance and displacement.
Answer:
y ≠ 0
Explanation:
The plot is asymptotic to the x and y axes in the first and third quadrants
Most ultrasound technicians train in an associates degree, but can also get a bachelors degree in the field. There is also certification programs you can go through. Hope this helped!!! :)
