Answer:
1) joule
2)
3)
Explanation:
1) Luminosity is the <u>amount of light emitted</u> (measured in Joule) by an object in a unit of<u> time</u> (measured in seconds). Hence in SI units luminosity is expressed as joules per second (), which is equal to Watts ().
This amount of light emitted is also called radiated electromagnetic power, and when this is measured in relation with time, the result is also called radiant power emitted by a light-emitting object.
Therefore, if we want to calculate luminosity the Joule as a unit will be used.
2) Work is expressed as force multiplied by the distane :
Where force has units of and distance units of .
If we input the units we will have:
This is 1Joule () in the SI system, which is also equal to
3) The formula to calculate the percent error is:
Where:
is the experimental value
is the accepted value
This is the percent error
A leak means air escapes, so the car wouldn't brake.
Answer:
The refractive index of material of prism is 1.06.
Explanation:
Given that,
Angle of prism, A = 40 degrees
Angle of deviation,
We need to find the refractive index of material of prism. We know that the relation between angle of deviation, prism angle and the refractive index is given by :
is the refractive index of material of prism
So, the refractive index of material of prism is 1.06. Hence, this is the required solution.

Explanation:
Answer:
Solution:
As per the question:
Initial frequency of the processor, f = 2.5 GHz =
Final frequency attained by the processor, f' =
Initial dynamic power,
Leakage Power,
Now,
To calculate the Dynamic power, and leakage power consumed by the processor:
We know that the dynamic power is in direct proportion to the frequency of the processor:
∝ frequency, f
Thus we can write:
Substituting the appropriate values in the above expression:
Now,
We know that the leakage power does not depend on the frequency of the processor and hence remains same.
Thus
Hope this helps, have a great day ahead!
