Answer:
Explained
Explanation:
Thickness coating= t
wavelength of light λ = 500 nm
2 t =(m+0.5)λ
Here m = 0
t= λ/4
= 500/4 nm
= 125 nm
= 125×10^(-9) m
Answer:
Radius of the track is 3376.40 n
Explanation:
We have given speed v = 75.75 km/hr =
Mass is given m = 92 kg
Centripetal force is given F = 12.8 N
We have to find the radius of the curve
Centripetal force is equal to
So
r = 3376.40 m
So radius of the circular track is 3376.40 m as the SI unit is m so it will be 3376.40 m
Kevin is a unit used to measure temperature
The temperature rises of in the block if the current flows for 10 minutes is, 34.78K.
To find the answer, we need to know about the power of the electric heater.
<h3>How to find the temperature rise of in the block if the current flows for 10 minutes?</h3>
- We have given with the variables,
- We have an expression the heat given to the system as,
ΔT
- We have to find the temperature rise ΔT,
ΔT
Thus, we can conclude that, the temperature rises in the block if the current flows for 10 minute is 34.78K.
