il63 [147K]3 years ago
5 0

Answer:

  • Its density is 0.75 grams per cubic centimeters.

Explanation:

<u>Given that</u>:

  • A chocolate brownie has a volume of 360 cubic centimeters and a mass of 270 grams.

<u>To Calculate</u>:

  • Its density.

<u>We know that</u>:

  • Density = Mass/Volume

<u>We have</u>:

  • Mass = 270 g
  • Volume = 360 cc

<u>Finding its density</u>:

⟶ Density = 270/360

⟶ Density = 0.75

<u>Hence</u>,

  • Its density is 0.75 g/cc.

The correctly balanced equation for H2O2 → H2O + O2 is
Citrus2011 [14]

Answer:2H2O2 → 2H2O + O2

Explanation:

For a chemical equation to be balanced, the number of moles of each element at the reactant must be equal to that of the product.

According to the equation given

H2O2 → H2O + O2

There are two hydrogen atoms with two oxygen atoms at the reactant and 2hydrogen and 3oxygen at the product which shows the equation is not balanced. To balance this,

We will add 2 moles to H2O2 at the reactant and 2 moles to H2O at the product to give;

2H2O2 → 2H2O + O2 (Balanced equation)

As we can see that we now have 4 moles of Hydrogen and 4 moles of oxygen at both reactant and product making the equation balanced.

An AC generator has an output rms voltage of 100.0 V at a frequency of 42.0 Hz. If the generator is connected across a 45.0-mH i
Rus_ich [418]

Answer:

(a) 11.8692‬ ohm

(b) 12.447 A

(c) 17.6 A

Explanation:

a)  inductive reactance Z = L Ω

    = L x 2π x F

    = 45.0 x 10⁻³ x 2(3.14) x 42

    = 11.8692‬ ohm

b) rms current

    = 100 / 8.034

    = 12.447 A

c) maximum current in the circuit

    = I eff x rac2

    = 12.447 x 1.414

    = 17.6 A

The Sloan Digital Sky Survey includes many thousands of galaxies in its spectroscopic catalogs. How are the distances to most of
Katarina [22]

The distances to the most of these galaxies estimated from their red shifts and the application of Hubble's Law.

<h3>What is Hubble's Law?</h3>

The discovery in physical cosmology that galaxies are travelling away from Earth at rates proportionate to their distance is known as Hubble's law, often referred to as the Hubble-Lemaître law or Lemaître's law. In other words, they are travelling away from Earth more quickly the more away they are. The redshift of the galaxies—a shift in the light they produce toward the red end of the visible spectrum—has been used to calculate their velocities.
