Answer:

Energy is force times distance. For your problem, no matter how long you push, the wall still goes nowhere, so there is no obvious energy transfer. so in conclusion, you actually didn't do anything :(

Answer is
Work = (Distance / Time) Example 35 Miles per Gallon.

Since the wall did NOT move you did did not actually do any work.

I hope this helps you.

In a tug of war, two teams exerts a force of 30 N each. What is the net force acting on the rope?
Arte-miy333 [17]

The force exerted by each team is 30 N. The forces are in the direction opposite to each other.

Force exerted by team 1, F_{1}=30 N

Force exerted by team 2,F_{2}=-30 N

Net force, F=F_{1} +F_{2}

=30+(-30)=0

Therefore, net force on the rope is 0 N.

An electric generator converts kinetic energy into which kind of energy?
dem82 [27]

Answer:

Electrical Energy

Explanation:

An electric generator is a device that changes kinetic energy to electrical energy through electromagnetic induction. Electromagnetic induction is the process of generating electric current with a magnetic field. ... Because the coil is rotating in a magnetic field, electric current is generated in the wire.

Science Seminar Question: Why did Vehicle 2 fall off the cliff in Claire's test of the collision scene but Vehicle 2 did not fal
asambeis [7]

Complete Question:

Check the file attached to get the complete question

Answer:

In the film Ice word Revenge, vehicle 2 did not fall of the cliff because, Weight_{vehicle 1} < Weight_{vehicle 2} but in Claire's test, vehicle 2 off the cliff because Weight_{vehicle 1} \geq Weight_{vehicle 2}

Explanation:

In Claire's test, the weight of vehicle 1 is either equal to or greater than the weight of vehicle 2, so it was sufficient to push it down the cliff.  In the film Ice word revenge, the weight of vehicle 1 is less than the weight of vehicle 2, it is not sufficient to make it fall off the cliff ( Note: Looking exactly the same in the movie, as Claire claimed, does not mean they have the same mass). Therefore if Claire wants a collision that will not make the vehicle 2 fall off the cliff, he should collide it with a vehicle of lesser mass/weight.

A 3 kg ball rolls at 2m/s does this system favor kinetic energy or potential energy?
MissTica

Answer:

Kinetic energy

Explanation:

Total energy of any  system is always conserved.

E = K +U

E= Total energy

K = kinetic energy

U = Potential energy

Kinetic energy is the energy acquired by the system due to the virtue of it's motion.

Potential energy is the energy acquired by the system due to the virtue of it's configuration.

Also, Kinetic energy K = \frac{1}{2} m v^{2}

K = \frac{1}{2} \times 3 \times 2^{2}

K = 6 J
