Answer:
Electric force, F = 20.16 N
Explanation:
It is given that,
Charge on gold nucleus,
An electron is sent at high speed toward a gold nucleus,
Distance between electron and gold nucleus,
We need to find the electric force acting on the electron. The formula for electrostatic force is given by :
F = 20.16 N
The electric force acting on the electron is 20.16 N. Hence, this is the required solution.
For uniform acceleration (or deceleration in this case), you use the formula:
Vf = Vi + at
Vi = 22 m/s
Vf = 0 (coming to a stop)
t = 5 sec
Plugging everything into the formula gives you:
0 = 22 + 5a
-22 = 5a
a = -22/5 or -4.4 m/s^2
Hope this helps!
it is important so you can discover new materials or inhabitle planets in case anything happens to earth
Answer:
The views of scientific knowledge can change over time. Changes can result from new science observations, but can also be affected by social, political or religious reasons.To develop a deeper understanding, we need to investigate the reason for that, that how it's happening why it's happening etc.
