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.
The answer is ultra violet radiation. From the air
Answer: work = 1,305kJ
Explanation:
angle= 30°
force= 1,500N
distance= 1,000m
The formula for work is : Work= force x distance, however there is an angle of 30° between the direction of force applied and the direction of motion, therefore force must be decomposed to its value on the horizontal axis which is the direction of motion by using the cosine of the very angle.
W= F×cos(α)×D
W= 1,500×cos (30)×1,000
W= 1,305kJ ( kilojoules)
It comes from the sun, and then it is converted to energy/electricity (by solar panels)
Answer:
I would believe that it would be the last option
