Answer:
The rider's speed will be approximately 35 m/s
Explanation:
Initially the rider has kinetic and potential energy, and after going down the hill, some of the potencial energy turns into kinetic energy. So using the conservation of energy, we have that:
The kinetic and potencial energy are given by:
So we have that:
So the rider's speed will be approximately 35 m/s
Gravity..? I don't know, but you need to clear up your question a bit. I'm sure it's gravity though.
The "Temperature" scale has a single "anchor" point at the triple point of water.
In short, Your Answer would be "Temperature"
Hope this helps!
The answer is d) protons were created as the results of the charging process
1) PE=mgh
mass 50 kg; height 3; g 9.81
50×3×9.81=1471.5 J
2. The student is opposing gravity force so
Fgrav=m×g
50 × 9.81= 490N
Work=force×displacement
490×3=1470J(this should always be the same as the potential energy)
3.Power=work×time
4410 W=1470×3
4. Greater than: power is dependent on work, work is dependent on force, force is dependent on weight,
