Answer:
vf = 4.01 m/s
Explanation:
According to the law of conservation of energy:
where,
vf = final speed of ball at top of the ramp = ?
vi = initial speed of ball = 2.62 m/s
g = acceleration due to gravity = 9.81 m/s²
h = height = 0.47 m
Therefore,
<u>vf = 4.01 m/s</u>
Answer;
- Nuclear fusion
Explanation;
-Hydrogen bombs and stars both produce energy with the nuclear fusion. On other side, the Sun and other stars make heat and light by nuclear reactions.
-The first stage of a hydrogen bomb involves a fission explosion which in turn leads to a nuclear fusion. The extreme heat and pressure from the initial atomic blast force together deuterium and tritium (two light gases made of hydrogen). When they are forced together, some of the hydrogen atoms fuse to one another, creating helium.
-This process of fusion releases even more energy per unit of mass than fission does, and the energy released from the fusion reaction also feeds back into the fission reaction, increasing its output.
Answer:
Stop cheating in exam
Explanation:
Shame!!!!
I am sorry but I will have to refer you to the student conduct at UTA.
Answer:I'm gonna say mechanical or kinetic depending on how you look at it.
Explanation:
No friction present means: Ek = Ep
So Ek = mgh = 10 * 9.8 * 2 = 196 J
