Anemometer, Psychrometer, <span>Barometer</span>
The electric power used by the car battery is given by
where
V is the voltage of the battety
I is the current
P is the electric power.
For the battery in our problem, the voltage is V=12.0 V while the current intensity is I=0.5 A, so the power used by the battery is
Answer:
220.7
Explanation:
distance traveled is 1.5*5=7.5m
PE gain is MGH=3*9.81*7.5=220.7
Answer:
Wavelength = 489.52 nm
Explanation:
Given that the wavelength of the light = 633 nm
The time taken by the light in unknown liquid = 1.38 ns
Also,
1 ns = 10⁻⁹ s
So, t = 1.38 × 10⁻⁹ s
Also,
Distance = 32.0 cm = 0.32 m ( 1 cm = 0.01 m)
<u>So, speed of the light in the liquid = Distance / Time = 0.32 / 1.38 × 10⁻⁹ m/s = 2.32 × 10⁸ m/s</u>
Frequency of the light does not change when light travels from one medium to another. So,
So,
<u>Wavelength = 489.52 nm</u>
