Why is there a change in rate of energy exchange as time passes?
There is a change in rate of energy transfer as time passes because of the amount of energy in both objects. -probably wrong
How do you solve for the power in physics?
Power is the rate of change of energy with time.
A measure of the rate at which work is done or energy is transformed?
Power is the rate of change of work with respect to time. It has units of [kg*m^2/s^3].
How does the rate of cooling water change?
because of the thermal energy being released from the hot water and dissipated into the air.
Is acceleration the rate of change of the rate of change of position?
no its speed that definds the rate change of position
Why is there a change in rate of energy exchange as time passes?
There is a change in rate of energy transfer as time passes because of the amount of energy in both objects. -probably wrong
Does your heart rate change your energy levels?
Yes, your heart rate will change your energy levels in many different ways. If you are working out you will have a higher heart rate and this will cause you to be tired after you work out.
How do you solve for the power in physics?
Power is the rate of change of energy with time.
How is the heart rate of a person running different from their resting heart rate why is this change necessary?
Because your heart needs to burn energy, the more energy you burn the faster your heart rate
How are electrical power and electrical energy related?
Power is always the time-rate of energy, i.e. the rate of change (or transfer) of energy with respect to time.If Energy is measured in Joules, then one Joule being transferred in one second is equal to one Watt of power.Electrical power is the time rate of change of electrical energy, P=dE/dt.Power = energy / timeIt usually referst to some type of energy transfer. In SI units:Watts = joules / second
Is it true that another way to control the rate of a reaction is to change the activation energy needed?
True
Does adding heat energy affect the rate of reaction in a chemical change?
it depends on what chemicals used
Is another way to control the rate of a reaction to change the activation energy needed?
Adding a catalyst.
What are two major factors that change the rate of a reaction?
heat (energy)/ concentration/ surface area
A measure of the rate at which work is done or energy is transformed?
Power is the rate of change of work with respect to time. It has units of [kg*m^2/s^3].
How does the rate of cooling water change?
because of the thermal energy being released from the hot water and dissipated into the air.
What is the rate at which the energy is transferred?
The rate at which energy is transferred is called POWER
