Answer:
6 V
Explanation:
In a circuit, the relationship between voltage, current and resistance is given by Ohm's law:

where
V is the voltage
R is the resistance
I is the current
In this circuit, we have
is the resistance
I = 0.500 A
so we can find the voltage of the battery by using Ohm's law:

Answer:
The angle is 1.33°.
Explanation:
Given that,
Distance 
Wavelength = 650 nm
Number of fringe = 3
We need to calculate the angle
Using formula of angle for brightness


Where, d = distance
=wavelength
m = number of fringe
Put the value into the formula


Hence, The angle is 1.33°.
Answer:
Inertia! I hope this helps!
I don’t understand what are you trying to do ?
The wavelength and frequency of the wave is altered, resulting in a change in the amount of energy carried.
