Answer:

D)they would generate so much power that they would blow themselves apart.

Explanation:

Stars contains helium and hydrogen gases with helium forming a large percentage. When a star is a few times greater than the Sun it could cause it to collapse into a black hole.

However when the mass of the star is 200 times greater than the sun, it means a larger percentage of helium gas which is formed by the fusion of hydrogen nuclei with a large amount of energy being the by product of this fusion process. This would make the Stars generate so much power that they would blow themselves apart.

Gauss's law: Group of answer choices can always be used to calculate the electric field. relates the electric field throughout s
kvasek [131]

Answer:

relates the electric field at points on a closed surface to the net charge enclosed by that surface.

Explanation:

Gauss Law states that overall electric flux of a closed surface is equivalent right to charge enclosed which is divided by the permittivity. In other words Gauss Law stress that

net electric flux that pass through an hypothetical closed surface is equivalent to overall electric charge present within that closed surface.

The Gauss law can be expressed mathematically as

ϕ = (Q/ϵ0)

Q = total charge within the surface,

ε0 = the electric constant

Hello everyone Lubricants are used in machines.Why?Hope u will answer it good day.Thank You✌️​
aalyn [17]

Answer:

Lubrication is used to reduce friction. It is generally used for moving machine parts. The lubricants are the substances which are used to reduce the friction which acts between two surfaces in contact, between which relative motion can occur.

During a neighborhood baseball game in a vacant lot, a particularly wild hit sends a 0.148 kg baseball crashing through the pane
LiRa [457]

Answer:

Explanation:

mass of baseball, m = 0.148 kg

initial velocity, u = 15.5 m/s

final velocity, v = 10.1 m/s

Impulse is defined as the change in momentum of the body.

Impulse = change in momentum

I = m (v - u)

I = 0.148 (10.1 - 15.5)

I = - 0.8 Ns
