Answer:
Electrons and protons are connected with one another in term of charge and size.
Explanation:
- The size of electron and proton is always same in any atom but they possess opposite charge.
- Electron in any atom carries negative charge where as proton carries the positive charge.
- In any neutral atom the charge between electron and proton is balanced along with the size.
- The nucleus of any atom bounds only proton and neutron but the electron is present revolving around the nucleus.
Compressional waves can travel through all states of matter.
Answer:
31.905 ft/s²
Explanation:
Given that
Mass of the pilot, m = 120 lb
Weight of the pilot, w = 119 lbf
Acceleration due to gravity, g = 32.05 ft/s²
Local acceleration of gravity of found by using the relation
Weight in lbf = Mass in lb * (local acceleration/32.174 lbft/s²)
119 = 120 * a/32. 174
119 * 32.174 = 120a
a = 3828.706 / 120
a = 31.905 ft/s²
Therefore, the local acceleration due to gravity at that elevation is 31.905 ft/s²
Answer:
∆PE = 749.7 J
At 0.9 m high, PE = 793.8 J
At 1.75 m high, PE = 1543.5 J
