In a double-slit arrangement, the slits are separated by a distance equal to 100 times the wavelength of the light passing throu

VladimirAG [237]

Solution :

The conditions for the maximum in the Young's experiment is :

d sin θ = m λ, where m = 0, 1, 2, 3, .....

The angle between the central maximum and the 1st order maximum can be determined by setting the m = 1. So,

d sin θ = λ

$\theta = \sin^{-1}\left(\frac{\lambda}{d}\right)$

Given : d = 100 λ

$\theta = \sin^{-1}\left(\frac{\lambda}{100 \lambda}\right)$

$\theta = \sin^{-1}\left(\frac{1}{100}\right)$

$=0.573^\circ$

The atmosphere pressure can support mercury in a tube, which the upper end is closed, up to 0.76 meter. If the mercury is replac

Leni [432]

Answer:

Maximum height the atmosphere pressure can support the

water=10.336 m

Explanation:

We know that ,

$Pressure = h\cdot\rho\cdot g$

Case 1 - Mercury in the tube

$Density\ of\ mercury =\rho_1\\and\ height\ attained\ for\ mercury\ column = h_1$

Case 2 - Water in the tube

$Density\ of\ water =\rho_2\\and\ height\ attained\ for\ water\ column = h_2$

Since atmospheric pressure is same

. $P=h_1\cdot\rho_1\cdot g = h_2\cdot\rho_2\cdot g$

or, $h_2=\frac{h_1\rho_1}{\rho_2}$

$Given\ h_1= 0.76\ m,\rho_1=13.6\cdot\rho_2$

∴ $h_2=0.76\cdot13.6=10.336\ m$

Hence height of the water column =10.336 m

20 points plz help i dont really understand how to do this

Artist 52 [7]

$\huge{ \mathfrak{ \underline{ Answer} \: \: ✓ }}$

1. Calculate the equivalent resistance in the circuit :

In the given diagram, the resistors are in series connection,

So equivalent resistance = sum of resistance of both resistors.

$\large \boxed{R_{eq} =R_1 +R_2 }$

$R_{eq} = 480 + 360$

$R_{eq} = 840 \: ohms$

Therefore, Equivalent resistance = 840 ohms.

2. Calculate the current through the battery :

$\boxed{ \mathrm{current = \dfrac{potential \: \: difference}{resistance} }}$

$i = \dfrac{120}{840}$

$i = \dfrac{1}{7}$

$i = 0.142 \: Amperes$

Hence, current through the battery = 0.142 A

3. How much current is passing through each resistor :

Since the resistors are joined in series connection, the current flowing through each resistor will be equal = 0.142 Amperes.

A student said, "The displacement between my dorm and the lecture hall is 1 kilometer."

Ann [662]

Answer:

d) Both a and b are correct

Explanation:

Displacement: It is defined as the distance between initial and final position during motion.

Distance: It is defined as the total path length traveled by object

It is the distance of one place from other place.

Student said that the displacement between my dorm and the lecture hall is 1km.

It is not displacement .It is distance or we say path length.

Therefore, he is using incorrect physical quantity for the information provided.

He should have called distance 1 km or path length 1 km.

Option d is true.
