The appropriate response is hydrogen ions. It entirely, the core of a hydrogen particle isolated from its going with an electron. The hydrogen core is comprised of a molecule conveying a unit positive electric charge, called a proton.
I hope the answer will help you.
They require a medium to travel through
Please elaborate more on your question so I can help you
Answer:
The power of a weightlifter is 100.5 Watt.
Explanation:
- Power is the rate at which the work is done. It can also be defined as the amount of energy converted or transferred in to other forms per unit time.
- Mathematically,
Power=Workdone/Timetaken
- In this case, work is done by lifting the 614.7 N barbell against gravity given by the potential energy.
- Potential Energy = mgh= Force* distance= 614.7*4.48=2753.85 J.
- Now, Power= Workdone/Timetaken= 2753.85/27.4=100.5 Watts
Therefore, the power of a weight lifter when a 614.7 N barbell is lifted 4.48 m in 27.4 seconds is 100.5 Watt.
When density increases the number of molecules stay the same, im not entirely sure but i hope its right.
