I hate science class
Productivity is how much stuff you are able to get done without distractions. This can be in terms of how much work or homework or cleaning you can accomplish.
Power is the rate at which work is done or energy is transferred. It is calculated by dividing the work done or energy transferred by the time taken to do that work or transfer that energy. Mathematically, power = work/time or power = energy/time. The SI unit of power is the watt (W).
Done ith much energy.
the question is uncorrect i think heat was never invented.heat is just transfer if energy, say from fire what Franklin had done was invent a heat stove which was much more efficient for its time.
as little as 10% of the energy at any trophic level is transfer to the next level
Only 10% of the energy in one level gets to the next. The other 90% is used on movement. If you can figure out how much energy is in one trophic level, you can get how much energy gets to the next level by multiplying it by 0.1
In a typical energy transfer scenario, only about 10% of the energy from one trophic level is passed on to the next level. If the producer has 100 units of energy, approximately 10 units will be available for the primary consumer. This is due to the energy loss that occurs through metabolic processes and heat during energy transfer.
Work is simply a transfer of energy. Calculate the kinetic energy for both speeds, then calculate the difference. The formula for kinetic energy is KE = (1/2)mv2. If the mass is in kilograms, and the velocity (or speed) is in meter/second, the energy is in Joule.
The relationship between energy and force affects the motion of objects by determining how much work is done on the object. When a force acts on an object, it can transfer energy to the object, causing it to move. The amount of force applied and the distance over which it is applied determine the amount of energy transferred and the resulting motion of the object.
Energy transfer between consumers and producers is not 100% efficient. Some energy is lost as heat during each step of the transfer. Generally, only about 10% of the energy from one trophic level is transferred to the next level. This inefficiency results in a pyramid-shaped energy transfer model in an ecosystem.
A watt is a unit of power, not of energy. The international unit for energy is the joule. One watt is an energy transfer of one joule per second.A watt is a unit of power, not of energy.

Thermal energy transfer between substances is described by the amount of heat exchanged, measured in units of energy such as Joules or calories. The amount of thermal energy transferred depends on factors like the temperature difference between the substances, their specific heat capacities, and the mass of the substances involved in the transfer. This transfer can occur through conduction, convection, or radiation.
