The 'plum pudding' model of the atom was proposed by JJ Thomson, who had also discovered the electron. It was put forth before the discovery of the nucleus. According to this model, the atom is a sphere of positive charge, and negatively charged electrons are embedded in it to balance the total positive charge
Answer:
2A
Explanation:
Given parameter:
Quantity of charge = 2C
Time taken = 1s
Unknown:
The current passing through the ring = ?
Solution:
Current can also be defined as the quantity of charge that passes through a conductor per unit of time:
I =
So;
I = = 2A
As water vapour cools, it changes back into liquid form. drops come together to form 'clouds'? maybe
Average speed = Distance ÷ Time
Distance = 38 m + 1/2 of 38 m = 38 + 19 = 57 m
Time = 9 + 1.8 = 10.8 s
Average speed = 57/10.8 = 5.277 m/s
Average Velocity = Displacement ÷ Time
Displacement = 19m
Time = 9 + 1.8 = 10.8 s
Average velocity = 1.759 m/s
