What ia an example of kenitc energy?
Kinetic energy is anything that was in a resting position and is now moving. The resting position it is in is called gravitational potential energy.
The potential energy of a 50 newton object resting on the edge of a cliff 30 meters high is?
The word in your question that I keyed on is "resting". An object at rest has zero kinetic energy. If you meant potential energy, the answer is 1500 joules.
What is difference between potential and kinetic energy give two examples?
If the object is placed at height, it has potential energy and when this object falls down, this potential energy is converted to kinetic (kinesis means movement) energy. If we have to lift object at height , we have to spend energy, witch is released during fall of the object. Example is when water comes down in hydroelectric power station potential energy is converted into kinetic energy. Witch is used to rotate wheel, creating electricity.
Which has more kinetic energy a 50 g basketball resting on a chair or a 75 g basketball resting on the floor?
99 bill
What are 2 types of energy sources?
First, energy sources are usually split into kinetic and potential. Kinetic energy is the energy of something in motion: the earth in orbit about the sun has kinetic energy. The earth also has kinetic energy due to its rotation. The moon orbiting the earth has kinetic energy, but the moon does not rotate. A car zipping along the highway has kinetic energy as does a train moving on a track. Potential energy is something which can become energy. A rock resting on top of a building can fall off the edge and gravity will pull it downward faster and faster. We say it had potential energy on top of the building's gravity well and this became kinetic energy as it fell. When the rock strikes ground, its kinetic energy will convert to thermal energy warming it and the earth beneath it. Other forms of potential energy include water held by a dam, a gas which has been compressed, and chemicals which can react, such as chemical batteries.

Would a book on a table one meter above the floor have more kinetic energy than a book resting on a floor?
No. Kinetic energy would be zero in both cases. The book in the higher position has more potential energy.No. Kinetic energy would be zero in both cases. The book in the higher position has more potential energy.No. Kinetic energy would be zero in both cases. The book in the higher position has more potential energy.No. Kinetic energy would be zero in both cases. The book in the higher position has more potential energy.
Do all cells have a resting potential of -70mV?
No there is a range of resting potentials. For example retinal ganglion cells have a resting potential of -65 mV while the endocochlear potential is +80 mV.
A resting motor neuron is expected to?
exhibit a resting potential that is more negative than the "threshold" potential.
What is a resting motor neuron expected to do?
exhibit a resting potential that is more negative than the "threshold" potential
If a resting potential becomes more negative what happens to the cell?
When the membrane potential becomes more negative it is being hyperpolarized. Remember the resting membrane potential is already at a negative state (~70mV). So if you are making a comparison of a membrane potential that is hyperpolarized in comparison to a resting membrane potential, the resting membrane potential is said to be more depolarized.When the membrane potential becomes more positive it is called depolarization.

What about a cell's resting membrane potential is FALSE?
The resting membrane potential is maintained by solely by passive transport processes.
What is the charge on the inside membrane during the resting membrane potential?
The resting membrane potential of a typical neuron is around -65mV
What is the inside charge of a nerve at its resting potentail?
Neurons have a resting membrane potential of approximately -70mV. Muscle cells have a resting membrane potential of approximately -90mV.
When a cell is at rest?
resting potential
