A heat pump is a device that puts out heat. It involves pumping a lever over and over to get energy so it can work.
Using Newton's Second Law, F = ma, where F is the net force
So the net force is:
F = (6kg)(4m/s^2) = 24N
Since you are applying a horizontal force of 30N, we can find the force of friction by the difference of the net force and the applied force.
30N-24N = 6N
2) What must be connected for an electrical current to flow in a simple current?
<em>d.moving magnets,conductors, load to do work
</em>
here moving magnets will work as generator and conductors is used as connectors.
5)What is the purpose of a load in a circuit?
<em>c.provide resistance to keep the voltage strong
</em>
Load will provide the resistance to the circuit and help to build the voltage across it
6) What cause an electric current from a generator
<em>d.Magnets and conducting wires move near each other
</em>
here when magnets move near wires then it will induce the electric current and behaves like generators
7) What do all generators have in common
<em>b.they transform mechanical into electrical energy
</em>
They have magnets and rotating coils which will convert magnetic energy to electrical energy
8) How can we measure electrical current
<em>b.the pressure force is voltage;the # of electrons moving is amperes
</em>
this voltage and number of electrons will help to calculate current
Answer:
C is the answer
Explanation:
Earth is the third planet from the sun
you are cheating on your test, I know
The work output is 
Explanation:
The power of the snowmobile is

Keeping in mind that

We can convert it into Watts:

The energy used by the snowmobile can be found as follows:

where
P = 111,900 W is the power used
t = 15 s is the time interval
Substituting,

However, the snowmobile is 18% efficient: this means that only 18% of this energy is converted into useful work. Therefore, the work output is
