Answer and Explanation:
The hydrogen atom is an atom of hydrogen element.Hydrogen atoms contain one proton which has positive charge and one electron which has negative charge , so due to positive and negative charge present in the hydrogen atom its becomes neutral atom.In whole universe the hydrogen atom is found in most abundant. Electron and nucleus of the hydrogen atom is bound together with the help of coulomb force.
The gravitational potential energy is calculated by multiplying the mass of the object to the height and the gravitational acceleration which is 9.8 m/s^2. We do as follows:
GPE = mgh
GPE = 4942
4942 = m (9.8)(6.15)
m = 82 kg
Hope this helps.
Answer:
20 m/s
Explanation:
The relevant relationship is ...
speed = distance/time
speed = (100 m)/(5 s) = (100/5) m/s
speed = 20 m/s
The average speed is 20 meters per second.
