Which is an example of transforming potential energy to kinetic energy? Check all that apply. changing thermal energy to electrical energy changing chemical energy to thermal energy changing nuclear energy to radiant energy changing radiant energy to electrical energy changing mechanical energy to chemical energy

When we say potential energy, this is the energy at rest. And kinetic energy is the energy at motion. So, here are the examples of energy that is transforming from potential energy to kinetic energy: changing thermal energy to electrical energy, and changing radiant energy to electrical energy. Hope this answer helps.

If two carts collide, what type of collision will conserve both momentum and kinetic energy? a. head on b. perfectly inelastic c. none d. perfectly elastic

The appropriate answer is d. perfectly elastic. When a perfectly elastic collision occurs both momentum and kinetic energy are preserved. Momentum is the mass of an object times its velocity while kinetic energy is the energy that a moving object has due to its motion. In an elastic collision kinetic energy would be converted to some other form of energy.

A 10.00 g sample of a compound containing only carbon, hydrogen, and oxygen forms 23.98 g CO2 and 4.91 g H2O upon complete combustion. What is the empirical formula of the compound?

(23.98 g CO2) / (44.00964 g CO2/mol) × (1 mol C / 1 mol CO2) = 0.544881 mol C 
(0.544881 mol C) × (12.01078 g C/mol) = 6.54445 g C 

(4.91 g H2O) / (18.01532 g H2O/mol) × (2 mol H / 1 mol H2O) = 0.54509 mol H 
(0.54509 mol H) × (1.007947 g H/mol) = 0.54942 g H 

10 g total - 6.54445 g C - 0.54942 g H = 2.90613 g O 
(2.90613 g O) / (15.99943 g O/mol) = 0.18164 mol O 

Divide by the smallest number of moles: 
(0.544881 mol C) / 0.18164 mol = 2.9998 
(0.54509 mol H) / 0.18164 mol = 3.0009 
(0.18164 mol O) / 0.18164 mol = 1.0000 
Round to the nearest whole number to find the empirical formula: 
C3H3O

Casey has an open book test in his physics class tomorrow and will need to use many formulas. Which of the following is the best strategy Casey could use to organize his formulas?

For this case, there are two strategies that Casey can use for the exam.

1) Make a form: This technique consists of compiling the most important formulas found in the book and writing them on a single page. Then, when Casey must use a formula in the exam, it is easier for her to look in the sheet where she wrote the formulas.

2) Highlight formulas: This technique consists of using a highlighter to highlight the most important formulas in the book. So when Casey should look for a formula in the book, she should not read the whole text. She should only read the highlighted text.

The space shuttle travels at about 28,000 km per hour. Using that information, estimate how many hours it will take the shuttle to reach Saturn from Earth. Show your work. Convert your answer into scientific notation if necessary.

It depends what is the position of earth and saturn. Distance from earth to saturn varies depending on whether earth is between sun and saturn or sun is between earth and saturn. Obviously, the shortest distance will be if earth is between sun and saturn. we will take that the distance between earth and saturn is:

s = 1 275 000 000 km
The time required to travel that distance is:
t = s/v = 45535 hours or 1897.3 days

When an electric current is passed through water during the process of electrolysis, two gases are formed. One gas has a boiling point of -183 degrees celsius and the other has a boiling point of -253 degrees celsius. Has a physical change or a chemical change occurred? Explain.

The chemical change occurred. Electrolysis is used by scientists to make chemical reactions that wouldnt normaly spontaniously ocur. In this case we are getting new gases from water molecul which is change in structure of elements ( we are getting new moleculs)

I need help with forms of energy.

Electrical Energy

A bolt of lightening is electrical energy. This is the same kind energy used by an electrical outlet. Electrical energy travels through power lines and then helps make lots of different machines work.

Motion Energy:
Moving things have energy. The faster something is moving, the more energy it has. Pose this question to your students: Which do you think has more motion energy, a book that is falling off a table or a truck driving down the road at 60 miles per hour? You can explain that the truck has more motion energy because it is traveling much faster than a book. Another reason why the truck has more motion energy is that the truck is much heavier than the book.

What does it mean that a form of energy might take more energy to harness than it provides? Are renewable resources always renewable, or can they become non-renewable? Why aren't renewable resources used for everything that we use energy for? Explain.

A form of energy might take more energy to harness than it provides because of dissipated energy. During the transformation process, not all of the energy will be converted to useful energy. Some of the energy are dissipated in the form of heat. Renewable resources are resources that are replenished at a faster rate than they are used. They become non-renewable when these resources are used up at a faster rate than they are replenished. We don't use renewable resources for everything that we use energy for because the energy transformation might be inefficient or requires a lot of capital and maintenance.
