If you are referring to stars, the answer would then be pressure from the nuclear reactions

The thermal pressure that pushes outward and against the pull of gravity in a star is caused by the nuclear reactions that is happening within the stars core. A lot of energy is released during these reactions which produce thermal pressure. The pressure then pushes outward.

1. An object has a mass of 10g and a volume of 50mL. What is the density?

Alona [7]

1. 0.2 g/mL

The relationship between mass, density and volume of an object is

$d=\frac{m}{V}$

where

d is the density

m is the mass

V is the volume

For the object in this problem, we have

m = 10 g

V = 50 mL

Substituting into the equation,

$d=\frac{10}{50}=0.2 g/mL$

2. 10 mL

In this exercise we know:

- The density of the object: d = 2 g/mL

- The mass of the object: m = 20 g

Therefore, we can re-arrange the previous equation to find the volume:

$V=\frac{m}{d}$

And substituting values into the equation, we find

$V=\frac{20}{2}=10 mL$

What is the difference between prokaryotic and eukaryotic?

AVprozaik [17]

Answer:

Prokaryotes are organisms that consist of a single prokaryotic cell. Eukaryotic cells are found in plants, animals, fungi, and protists. They range from 10–100 μm in diameter, and their DNA is contained within a membrane-bound nucleus. Eukaryotes are organisms containing eukaryotic cells.

A rod 25 cm long moves in a plane perpendicular to a magnetic field of 600 G. The velocity of the rod is perpendicular to its le

Airida [17]

Answer:

v = 666.667 m/s

Explanation:

<u>Given</u>: length L = 25 cm = 0.25 m, B = 600 G = 0.06 T ( 1G = 0.0001 T)

emf= 10 V

Solution:

emf = vBL

v= emf / BL

v = 10 V / (0.06 T× 0.25 m)

v = 666.667 m/s
