Newton's first law of motion is that an object in motion will tend to stay in motion unless an external force acts upon it.
Answer:
11700j
Explanation:
add the two because the plate has to maintain the temp.
2700+9000=11700
Answer:
all of the above
Explanation:
- a build up of electric charge
- the force and motion of electrically charged particles
- an electric current
are three different ways to describe electricity.
So the answer is all of the above.
you can find it using the equation: potential energy=mass*gravitational acceleration*height.
energy=50kg*9.8N/kg*40m=19600Nm=19600J or 19.6kJ
Sometimes they use 10 instead of 9.8 for the g constant.
