Answer: By Doppler effect

Explanation:

The spectrum of the objects in the universe such as stars and galaxies is taken and studied. The apparent change in the frequency/wavelength of the light suggests the motion of these objects.

If the apparent frequency is greater, the light would be blue -shifted which means it is moving towards Earth and if it is red shifted, it would be moving away from the earth. This is apparent change in observed frequency is known as Doppler's effect which studied to determine the motion of objects in the universe.

bonnie pulls a cart that weighs 195 N with a force of 18.0 N. According to Newton's 3rd law, with what force does the cart pull
motikmotik

Answer:

The force exerted by the cart on Bonnie is - 18.0 N

Explanation:

Given;

weight of the cart, w = 195 N

Bonnie's applied force on the cart, F = 18.0 N

According to Newton's 3rd law, action and reaction are equal and opposite.

Thus, the cart will pull back at Bonnie with force of equal magnitude but in opposite direction.

The force exerted by the cart on Bonnie = - 18.0 N

The following is a chemical reaction for _______ with ozone.
Andreas93 [3]

a.  chlorofluorocarbons

Explanation:

The chemical reaction describes the combination of chlorofluorocarbons with ozone.

Reaction 1: ClO + BrO   ⇒  Cl + Br + O₂

Reaction 2:  Cl + O₃ ⇒ ClO + O₂

Reaction 3: Br + O₃  ⇒  BrO + O₂

O₃ is the ozone molecule, the Cl, and Br are the chlorofluorocarbons.

  • In this reaction, ozone is converted into oxygen gas. This reaction takes place in the stratosphere.
  • This leads to the penetration and creation of a hole in the atmosphere which allows for ultraviolet rays to reach the earth surface.
  • The chlorofluorocarbons are produced on the earth surface in component gases used for making refrigerants, car sprays, air conditioners etc.
  • When the reach the ozone layer, they react with it and produce oxygen gas.
