Answer:
2.83m
Explanation:
The information that we have is
Intensity at 2.0 m: and
we need an intensity level of:
thus, we are looking for the distance .
which we can find with the law for intensity and distance:
we solve for :
and we substitute the known values:
at a distance of 2.83m the intensity level is 40dB
Ionizing radiation released from nuclear accidents does cause cancer but there have been only a small number of accidents so determining if it is not safe is a matter of opinion.
Answer:
Friction force is 0.1375 N
Solution:
As per the question:
Radius of the metal disc, R = 4.0 cm = 0.04 m
Magnetic field, B = 1.25 T
Current, I = 5.5 A
Force on a current carrying conductor in a magnetic field is given by considering it on a differential element:
Integrating the above eqn:
(1)
Now the torque is given by:
(2)
From eqn (1) and (2):
Thus the Frictional force is given by:
Answer: distance
Explanation:
Speed equals distance over time
Meaning time is on y axis and distance is on x axis
Time will always, Always be on y axis
So in any formula time will be on y axis and your other unit will be on x axis in this case s=d/t d being distance
