Answer:

Cells are able to receive energy from a wide variety of sources, depending on the type of organism that they are a part of. ... Our cells break down the sugars, fats, carbohydrates and proteins found in our food and convert them into the energy they need to keep our bodies going

Monochromatic light is incident on a grating that is 75 mmwide

statuscvo [17]

Answer:

Explanation:

Given

Grating Width $w=75 mm$

no of lines $N=50,000 lines$

inclination of second order maxima $\theta =32.5^{\circ}$

Condition of maxima For Diffraction grating

$d\sin \theta =m\lambda$

where $d=Grating\ constant$

$\lambda =wavelength$

$m=order\ of\ maxima$

$d=\frac{width}{N}$

$d=\frac{75}{50,000}$

$d=0.0015\ mm$

therefore for second order maxima wavelength of light is given by

$\lambda =\frac{d\sin \theta }{m}$

$\lambda =\frac{0.0015\times \sin (32.5)}{2}$

$\lambda =403\times 10^{-6}\ m$

$\lambda =403\ nm$

Two sources of in-phase coherent sound are located at the points (0 m, 2 m) and (-2 m, 0 m). An observer at the origin hears con

Korolek [52]

Answer:

c) 335 Hz

Explanation:

Given that the two sources:

S₁ ≡ (0 m, 2 m)

S₂ ≡ (-2 m, 0 m)

The lady hears the destructive interference for the first time when she reaches the point (0.6 m, 0 m).

So, the path difference = Δx = |S₂P - S₁P|

$S_2P=\sqrt {(-2-0.6)^2+(0-0)^2}=2.6\ m$

$S_1P=\sqrt {(0-0.6)^2+(2-0)^2}=2.0881\ m$

So,

Δx = |2.6 - 2.0881| = 0.5119 m

For, first destructive interference, Δx = λ / 2

So,

Wavelength = 1.0238 m

Also,

c = ν×λ

Where,

c is the speed of sound wave having value as 346 m/s

ν is the frequency

λ is the wavelength

So,

A mini rail gun made of a copper rod of mass m and radius r rests on two parallel copper rails that are a distance L apart and o

ira [324]

Answer:

Explanation:

Magnetic Force on the rod F = Bi L

Work done by this force = F X d

= Bi Ld

This energy is converted into both rotational and linear kinetic energy

= 1/2 I ω² + 1/2 mv²

= 1/2 x 1/2 m r²ω²+ 1/2 mv²

= 1/4 m v² + 1/2 mv²

= 3/4 mv²

So according to conservation of energy

Bi Ld = 3/4 mv²

v = $\sqrt{\frac{4BiLd}{3m} }$

What force is described as the attraction between a sample of matter and all other matter in the universe?

Vinil7 [7]

Answer:

Gravitational Force

Explanation:

Gravitational force also called gravity or gravitation is an attractive force that keeps two objects in space. Gravitational force is an attractive force that tends to pull matters together. Every objects in the universe experience gravitational pull. Planets, stars, galaxies, are held together by gravity. It is a weak force. The weight of an object is the product of gravitational force acting on its mass.

Newton's Law of Universal Gravitation states the force of attraction between two masses m₁ and m₂ in the universe is directly proportional to the product of their masses and inversely proportional to the square of their distance apart.

$F = G\frac{m_{1}m_{2}}{r^2}$

Where;

F is the gravitational force,

G is the gravitational constant = 6.67 × 10¹¹ m³/kg/s,

m1 and m2 are the masses of the objects,

r is the distance between the centers of the masses
