Answer:

Most responsible for the formation of a star is gravitational force.

Explanation:

A fundamental force that acts between any two bodies having mass is the gravitational force. Though it is a weak force but it plays the major role in formation of the universe.

The stars are born in molecular cloud of dust and gases - the nebula. This cloud condenses under its own gravity and contracts to form the core. Further, more mass is gathered as the core starts spinning due to gravity.

When the nuclear fusion starts, the balance between the pressure and gravity holds the star together.

Thus, most responsible for the formation of a star is gravitational force.

Most responsible in the formation of stars is the GRAVITATIONAL Force. The gravitation force is a force that brings mass to one another to form the stars. Isaac Newton make a law of gravity. Star formation is included in the branch of Astronomy.

Find a model for simple harmonic motion that has an initial displacement (t=0) of 0 inches, an amplitude of 5 inches, and a freq

Svetach [21]

Answer:

The equation of simple harmonic motion is $y=5\sin{(8\pi t)}$

Explanation:

Given that,

Amplitude = 5 inches

Frequency $f= \dfrac{4}{3}$

As per the question initial displacement is zero at t = 0 for sine curve.

The displacement is zero so the phase difference will be zero.

We know that,

The general equation of simple harmonic motion

$y=A\sin(\omega t+\phi)$

Where, A = amplitude

$\omega$ = angular frequency

$\phi$ = phase shift

We need to calculate the time period

Using formula of frequency

$f=\dfrac{1}{T}$

$T=\dfrac{1}{f}$

Put the value into the formula

$T=\dfrac{1}{\dfrac{4}{3}}$

$T=\dfrac{3}{4}$

We need to calculate the angular frequency

Using formula of angular frequency

$\omega=\dfrac{2\pi}{T}$

$\omega=\dfrac{2\pi\times4}{3}$

Put the value into the general equation

$y=5\sin{(8\pi t)}$

Hence, The equation of simple harmonic motion is $y=5\sin{(8\pi t)}$

Jared is experimenting with a force that is attractive only and the weakest of the fundamental forces. He is experimenting with

yawa3891 [41]

Jared in experimenting with the Gravitational Force. It is considered to be the weakest of the four fundamental forces, Strong nuclear force as the strongest, this the force that binds the nucleus of an atom. Next would be the Electromagnetic Force which deals with the movements of electrons. Third would be the weak nuclear force, which deals with the radioactivity and decay. In measuring the relative strength, strong nuclear force would be at 1. Electromagnetic would be at 10^-3, Weak Nuclear force is at 10^-13 and the weakest gravitational force is at 10^-40.

two balls each with with a mass of 0.5 kg, collide on a pool table. is the law of conservation of momentum satisfied in this col

Harrizon [31]

Answer: yes, the law of conservation of momentum remains conserved always in a closed system.

Explanation:

Law of conservation of momentum states that initial momentum of the components in a closed system is equal to final momentum of the components. Thus, the total momentum remains constant i.e. conserved. The law of conservation of momentum hold true in all conditions - be it elastic collision or inelastic collision.

When two balls collide on pool table, the law of conservation of momentum is satisfied.
