What is an example of kenetic energy being transformed to electrical energy?
The rotational force of an electrical generator using magnetism to create an electrical current.
If the velocity of an object is halved how has the amount of kenetic energy changed?
Using the equation for kenetic energy [KE=1/2*(X kg)*(V m/s)squared], KE will be reduced by V[squared]*(1/2), or 4x.
Which of the following is using chemical potential energy?
Answer this question… A hiker eating an energy bar
Which of the following is not a potential problem of using more nuclear energy?
They can provide a lot of energy for people to use - Apex
Scientists may be able to produce electrical energy from bacteria using the following strategy?
Harnessing photosynthetic processes
Which of the following makes its own food using energy from the sun?
Autotroph (Plants, Trees, etc.)
How do you make a model on energy conservation?
You can easily make working models displaying energy conservation using the following: solar panels; wind turbines; and hydro electricity.
What happens to the speed of body when kinetic energy increase by four times?
Using; ke = (m x v^2) / 2 where ke = kenetic energy, m = mass and v = velocity, velocity has to be halved when the mass is multiplied by four in order to maintain the same kinetic energy.
Catabolism primarily occurs?
It happens when your body has no other energy to use apart from lean muscle tissue, it usually occurs during long periods of cardio (about an hour +) or when you don't have sufficient nutrient intake, like enough carbs, your body will result to using muscle.
What is an energy using item?
the answer to this question is a television is an energy using item!
Which of the following best represents potential energy?
well without any examples you can't answer this question but a roller coaster would be a example because when its moving its using the kinetic energy that's been stored up
What energy do you get from the solar system?
That depends on what you are using to capture energy, if you are using solar panels to get it, then you are converting solar energy into electrical energy.
