Answer:
6 Joules
Explanation:
The change in internal energy must be equal the work done by pushing the handle with a 20 N force a distance of 0.3 meters. That is:
Change in internal energy = Work = 20 * 0.3 J = 6 Joules
PHYSICS
*not sure about the answer but here we go*
Mass = 425 kg
distance = 614.4 m
acceleration = 1.8 m/s²
Answer :
Count Force first.
F = 425 × 1,8
F = 765 N ✅
Now let's count Work.
W = 765 × 614.4
W = 470016 J ✅
The answer is 4.7 m for the spàthan. this is a very question! I hope this helps my friend! :-)
<span>The correct option is C. Energy cannot be created or destroyed. This statement is known as law of conservation of energy, and it implies that whenever a certain form of energy does change, the loss of this form of energy must have converted into an another type of energy. A typical example is an object falling to the ground: initially, the object has gravitational potential energy. As the object falls down, it loses potential energy (since its altitude from the grounf decreases), but it acquires kinetic energy (because its velocity increases). In this example, potential energy has converted into kinetic energy, but the total energy of the object has remained constant.</span>
