What does the big bang theory suggest

Physics
1 answer:
Alika [10]3 years ago
7 0

Answer:

The Big Bang Theory is the leading explanation about how the universe began. At its simplest, it says the universe as we know it started with a small singularity, then inflated over the next 13.8 billion years to the cosmos that we know today.

Explanation: Hope this help! :)

A mass of 1.03 kilograms is placed on a horizontal frictionless surface against an uncompressed spring with spring constant 861.
Lelechka [254]

Answer:

5.522 m

Explanation:

Data provided:

Mass, m = 1.03 kg

spring constant, k = 861.1 N/m

Distance by which the spring is compressed, x = 0.36

Thus,

the energy stored in the spring = \frac{1}{2}kx^2

on substituting the values, we get

the energy stored in the spring =  \frac{1}{2}\times861.1\times0.36^2

now,

by the conservation of energy, we have

Potential energy gained by the mass =  Energy gained by the spring

or

mgh = \frac{1}{2}\times861.1\times0.36^2

where,

g is the acceleration due to the gravity

h is the maximum height reached by the mass before falling

on substituting the values in the above relation, we get

1.03 × 9.81 × h = \frac{1}{2}\times861.1\times0.36^2

or

h = 5.522 m

An astronaut at rest in space with mass 84 kg fires a thruster that expels 35 g of hot
IRINA_888 [86]

Answer:

The velocity of the astronaut is, v = - 0.36 m/s

Explanation:

Given data,

The mass of the astronaut, M = 84 kg

The mass of the gas expelled by the thruster, m = 35 g

                                                                                 = 0.035 g

The velocity of the gas expelled, v = 875 m/s

According to the conservation of momentum,

             MV + mv = 0

                       V = - mv / M           

Substituting the values,

                        V = - 0.035 x 875 / 84

                           = - 0.36 m/s

The negative sign in the velocity indicates the astronaut moves opposite to the direction of velocity of gas.

Hence, the velocity of the astronaut is, v = - 0.36 m/s

Green light can have a wavelength of 512 nm. The energy of a photon of this light is
Nat2105 [25]

Answer:

E = 3.88 * 10^{-17} J

Explanation:

Energy is directly proportional to frequency and it is given as:

E = hf

where h = Planck's constant

f = frequency

To get frequency, we use the formula of speed:

c = λf

where c = speed of light

λ = wavelength

=> f = c/λ

Therefore, the energy of the photon will be:

E = hc/λ

E = \frac{6.626 * 10^{-34} * 3 * 10^{8}  }{512 * 10^{-9} }

E = 3.88 * 10^{-17} J

The energy of the photon is 3.88 * 10^{-17} J
