What is the relationship between globular clusters and the milky way?

Answers

Answer 1

Answer: Globular clusters are nearly spherical groups of about 10,000 to 1 million stars. A typical galaxy may contain up to a few hundred globular clusters; our galaxy, the Milky Way, has somewhere between 125 and 200 globular clusters orbiting the galactic center.

a relative density bottle has a mass of 29.2 g when empty its mass is 116.2 g when it is full of liquid or diesel and when full of water it's mass is 129.2 g calculate the relative density of diesel

Answers

Answer:

0.87

Explanation:

Given :

Mass of bottle = 29.2 g

Mass when filled with diesel = 116.2 g

Mass when filled with water = 129.2 g

The mass of water = (Mass when filled with water - mass of bottle)

Mass of water = 129.2 - 29.2 = 100 g

Mass of diesel = (Mass when filled with diesel - mass of bottle)

Mass of diesel = 116.2 - 29.2 = 87

Relative density of diesel = mass of diesel / mass of equal volume of water

Relative density = 87 / 100 = 0.87

You have a 2.00 kg block of lead. Lead melts at 327.5°C. Cpb = 130.0 J/kg*C and ?Hj for lead is 2.04x10^4 J/kg . Say you start at room temperature (25.0°C). How much heat must you transfer to melt all the lead?

Answers

Answer:

$1.2\cdot 10^5 J$

Explanation:

1) First of all, we need to calculate the heat needed to raise the temperature of the block of lead from the initial temperature (25.0 C) to the melting temperature (327.5 C). This heat is given by the equation

$Q_1 = m C_(pb) \Delta T$

where

m = 2.00 kg is the mass of the block

Cpb = 130.0 J/kg*C is the specific heat capacity of lead

$\Delta T=327.5 C-25.0 C=302.5 C$ is the temperature difference

Substituting,

$Q_1 = (2.00 kg) (130 J/kgC) (302.5 C)=7.87\cdot 10^4 J$

2) Now we have to calculate the amount of heat needed to completely melt the lead, which is given by:

$Q_2 = m Hj$

where

Hj = 2.04x10^4 J/kg is the latent heat of fusion of lead

Substituting,

$Q_2 = (2.00 kg)(2.04\cdot 10^4 J/kg)=4.08\cdot 10^4 J$

3) Therefore, the total heat needed is

$Q=Q_1+Q_2=7.87\cdot 10^4 J+4.08\cdot 10^4 J=1.2 \cdot 10^5 J$

Answer:

Q = 2.00kg x 130 J/kgC x 302.5C

Q = 7.87 x 10^4j

Q = 2.00kg x 2.04 x 20^4

Q= 4.08 x 10^4

Q = 7.87 x 10^4j + 4.08 x 10^4 = 1.2 x 10^5j

Answers

The correct answer (d.) epistemology. The major contribution of the French philosopher Rene Descartes was in the realm of epistemology. Epistemology is the theory of knowledge, including methods, validity, and its scope. It could also be concluded to separate justified fact from an opinion.

The answer is epistemology. So d epistemology.

Which two wire properties would provide the greatest resistance to the flow of a current?

Answers

Properties of wire, and things you can
do to it to make its resistance high:

-- Thickness. Make it as thin as a hair on a mosquito's leg.
