A snowball is rolling down a hill at 4.5 m/s and accumulating snow as it goes. Its diameter begins at 0.50 m and ends at the bot
Reil [10]
To find the change in centripetal acceleration, you should first look for the centripetal acceleration at the top of the hill and at the bottom of the hill.

The formula for centripetal acceleration is:
Centripetal Acceleration = v squared divided by r

where:
v = velocity, m/s
r= radium, m

assuming the velocity does not change:

at the top of the hill:
centripetal acceleration = (4.5 m/s^2) divided by 0.25 m
                                      = 81 m/s^2

at the bottom of the hill:
centripetal acceleration = (4.5 m/s^2) divided by 1.25 m
                                      = 16.2 m/s^2

to find the change in centripetal acceleration, take the difference of the two.
change in centripetal acceleration = centripetal acceleration at the top of the hill - centripetal acceleration at the bottom of the hill

= 81 m/s^2 - 16.2 m/s^2
= 64.8 m/s^2 or 65 m/s^2

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.

What would be the average fixed cost per unit at an activity level of 5,200 units? assume that this level of activity is within
Vitek1552 [10]

The average fixed cost per unit at an activity level of 5,200 units is $6.00.

<h3>What is the average fixed cost?</h3>

The average fixed cost (AFC) is fixed cost that does not change with the change in the number of goods and services produced by a company. To put it in a nutshell, average fixed cost (AFC) is the fixed cost per unit and is calculated by dividing the total fixed cost by output level.

Since no cost is fixed for a long time, average fixed cost is only for a short run. When units of production increase, the average fixed cost per unit decreases. Similarly, when the business produces less units, average cost increases per unit.

However, only one unit, mostly capital, is fixed. Examples of average fixed cost are the salaries of permanent employees, mortgage payment on machinery and plant, rent, more.

Average Fixed Cost Formula:

AFC = Total fixed cost/Output (Q)
