Which of these is the beginning of the life cycle of stars with different initial masses?
tigry1 [53]
The doppler effect, when used with light, produces a shift of frequencies to red. Well, no matter which direction you look, there is a shift to red! That means that the universe is expanding or moving away from us in every direction. The idea, is that this could only happen if all matter was once in a single point, and there was an explosion. This explosion from a single point is called the big bang theory.

Maru [420]

Answer:

A story that might be a good human interest story would be the vaccines for corona. Everyone these days are waiting desperately for corona to end. Talking about a vaccine might give them hope, and it would be nice to see how the scientist and doctors truly care for the people. Maybe encourage them to wear the masks until the vaccines come out?

1. A rock sample has a mass of 16 grams:
Morgarella [4.7K]

Answer:

(3) 4 cm' and 2.0 g/cm3

Explanation:

Given:

volume= V= 8 cm³

mass= m= 16 g

The density is the mass per volume of a substance, so the density of the rock is:

density= d= 16 g/8 cm³= 2 g/cm³

When we cut the rock in half, we have a half volume and a half mass:

V= 8 cm³/2= 4 cm³

m= 16 g/2= 8 g

But the density is not altered because it is an intrisic property - it does not change with the amount of subtance. Thus, the density of a half rock is:

d = m/V= 8 g/4 cm³= 2 g/cm³
