You have a double slit experiment, with the distance between the two slits to be 0.025 cm. A screern is 120 cm behind the double

dimulka [17.4K]

Answer:

The wavelength of the light is 633 nm.

Explanation:

Given that,

Distance between the two slits d= 0.025 cm

Distance between the screen and slits D = 120 cm

Distance between the slits y= 1.52 cm

We need to calculate the angle

Using formula of double slit

$\tan\theta=\dfrac{y}{D}$

Where, y = Distance between the slits

D = Distance between the screen and slits

Put the value into the formula

$\tan\theta=\dfrac{1.52}{120}$

$\theta=\tan^{-1}\dfrac{1.52}{120}$

$\theta=0.725$

We need to calculate the wavelength

Using formula of wavelength

$d\sin\theta=n\lambda$

Put the value into the formula

$0.025\times\sin0.725=5\times\lambda$

$\lambda=\dfrac{0.025\times10^{-2}\times\sin0.725}{5}$

$\lambda=6.326\times10^{-7}\ m$

$\lambda=633\ nm$

Hence, The wavelength of the light is 633 nm.

A notebook sitting on a desk has 19 j of potential energy. What is the total mechanical energy of the notebook?

Alex17521 [72]

The total mechanical energy of the notebook is <u><em>19J</em></u>.

Mechanical energy is the sum of potential energy and kinetic energy. It has no kinetic energy, because it's not moving. So its potential energy is all the mechanical energy it has.

Hey, I need help with my homework.

We have that the Average Force is given

Avg F=2.0488N

From the question we are told

Masses=

0.10

0.25

0.40

0.50

0.60

0.75

1.5

Accelerations

9.5

4.2

2.3

2.1

1.7

1.3

1.1

0.7

0.5

Generally the equation for the Mean is mathematically given as

For Mass

$X=\frac{\sum x}{n}\\\\X=\frac{0.10 +0.25+0.40+0.50+0.60+0.75+1+1.5+2}{9}\\\\X=0.788g$

For Acceleration

$X'=\frac{\sum x}{n}\\\\X'=\frac{9.5+4.2+2.3+2.1+1.7+1.3+1.1+0.7+0.5}{9}\\\\X'=2.6m/s^2$

Since Average Acceleration and mass are found above

Therefore

The Average Force is given as

Generally the equation for the Average Force is mathematically given as

$Avg F=Avg m *Avg a\\\\Avg F=0.788*2.6\\\\Avg F=2.0488$

Help me please I’m so bad at physics

aniked [119]

Answer:

C would probably be the best answer.

Explanation:

Switches control the flow of an electrical current in a circuit. Switches open or close the circuit. If you open a circuit, you turn it off, and if you close it, you turn it on.
