In a circuit with one 12.0 resistor, a current of 0.500 A is flowing. This circuit is powered by a single
Juliette [100K]

Answer:

6 V

Explanation:

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

V=RI

where

V is the voltage

R is the resistance

I is the current

In this circuit, we have

R=12.0\Omega is the resistance

I = 0.500 A

so we can find the voltage of the battery by using Ohm's law:

V=(12.0 \Omega)(0.500 A)=6 V

Two narrow slits 84 mum apart are illuminated with light of wavelength 650 nm. What is the angle of the m = 3 bright fringe in r
Digiron [165]

Answer:

The angle is 1.33°.

Explanation:

Given that,

Distance d=84\times10^{-6}\ m

Wavelength = 650 nm

Number of fringe = 3

We need to calculate the angle

Using formula of angle for brightness

d\sin\theta=m\lambda

\theta=\sin^{-1}\dfrac{m\lambda}{d}

Where, d = distance

\lambda =wavelength

m = number of fringe

Put the value into the formula

\theta=\sin^{-1}\dfrac{3\times650\times10^{-9}}{84\times10^{-6}}

\theta=1.33^{\circ}

Hence, The angle is 1.33°.
