Answer:

NS/NS

Explanation:

If we cut a bar magnet in half pieces according to the image that is given below the question, then the magnet will show NS/NS that is (North-South/North-South) because the smaller pieces of the magnet will become a small magnet with the same property-carrying both the poles, north pole as well as south pole. The poles will not be separated.

Laser light of wavelength 500.0 nm illuminates two identi- cal slits, producing an interference pattern on a screen 90.0 cm from

sergeinik [125]

The width and the separation of the two slits are 15μm and 45μm.

<h3>What is wavelength?</h3>

The wavelength is the distance between the adjacent crest or trough of the sinusoidal wave.

Given is the laser light of wavelength λ= 500.0 nm = 500x 10⁻⁹ m illuminates two identical slits, producing an interference pattern on a screen D =90.0 cm from the slits. the bright bands distance Δy = 1.00 cm apart, and the third bright bands on either side of the central maximum are missing in the pattern.

If d = separation between the two slits and a is the width of the slit

dsinθ/asinθ =m(max) λ/ m(min)λ

d/a = m(max) / m(min)..................(1)

where m(max)= ±3.0 and m(min)=1.0

So, d.a = 3

The distance from the central maxima to the third minimum fringe

y₃ = 3Δy

and the angle formed is

tan θ₃ = y₃/D or 3Δy/D

Put the values, we get

θ₃ =1.91°

From the equation, a sinθ = m(min)λ

a = 1 x 500 x 10⁻⁹/sin 1.91

a = 15 x 10⁻⁶ m or 15μm

From the equation, dsinθ= m(max) λ

d = 3 x 500 x 10⁻⁹/sin 1.91

d = 45 x 10⁻⁶ m or 45μm

Thus, the separation and the width are 45μm and 15μm

A water holding tank measures 105 m long, 40m wide, and 11m deep. Traces of mercury have been found in the tank, with a concentr

Hitman42 [59]

Answer: 2772mg

To answer this question first you must know how much the water tank volume. The calculation would be:
Water tank V: 105m x 40m x 11m= 46200m3

After that, you need to convert the m3 into liter, then multiply it with mercury mass index. The calculation would be
Mercury mass: 46200m3 x 0.001 l/m3 x 60mg/l = 2772mg

The electrical force on a 2-c charge is 60 n. the electric field where the charge is located is

Kazeer [188]

The electrical force acting on a charge q immersed in an electric field is equal to
$F=qE$
where
q is the charge
E is the strength of the electric field

In our problem, the charge is q=2 C, and the force experienced by it is
F=60 N
so we can re-arrange the previous formula to find the intensity of the electric field at the point where the charge is located:
$E= \frac{F}{q}= \frac{60 N}{2 C}=30 N/C$
