They undergo internal fertilization. They lose their tails as adults. They have wet, moist skin. They have long, strong legs. They begin life with gills.
The total mechanical energy is the sum of the kinetic energy and the gravitational potential energy:
where m=3.5 kg is Candy's mass, v=1 m/s is her velocity and h=3.5 m is her height. If we replace these numbers, we find the mechanical energy of the system:
All you need to do is plug in 3 for t:h=2+70(3)−16(3^2)
and the final answer is 68.
Answer:
a) y = 0.0075 m
b) W = 1.569 J

Answer:
Energy: Kinetic, Sound, Thermal, gravitational, electric, light and nuclear
Explanation:
This exercise asks to clarify a little some important concepts
* Energy. It is the capable one that has the bodies to carry out a job.
* Kinetic energy. It is the energy due to the movement of objects
* sound energy. It is the energy due to the vibration of the atoms or molecules of the materials, it can be solid, liquid or gaseous
* Thermal energy. It is the energy due to movement of the particles
* Gravitational Energy. It is a configuration energy due to the height of the bodies with respect to a reference point
* Electric power. It is due to the movement of electric charges
* light energy. It is the energy that light carries due to the electric and magnetic fields that form it, it occurs throughout the electromagnetic spectrum
* Nuclear energy. It is the energy stored in the nucleus by the configuration and movement of protons and neutrons.
