Kinetic energy = 1/2 (mass)*(velocity)^2
ke = 1/2 (1500kg) (17m/s)^2
ke = 216750 kg*m^2/s^2 = 216750 Joules
(sorry, I don't know significant figures. but this is otherwise the correct answer with the right units. hope this helps!! :))
Answer:

Explanation:
Given that:
p = magnitude of charge on a proton = 
k = Boltzmann constant = 
r = distance between the two carbon nuclei = 1.00 nm = 
Since a carbon nucleus contains 6 protons.
So, charge on a carbon nucleus is 
We know that the electric potential energy between two charges q and Q separated by a distance r is given by:

So, the potential energy between the two nuclei of carbon is as below:

Hence, the energy stored between two nuclei of carbon is
.
Answer:
0.47 N
Explanation:
q1 = 3.4 x 10^-6 C
q2 = 2 x 10^-6 C
d = 17.5 cm = 0.175 m
The electrostatic force is given by


F = 0.47 N
Thus, the force is 0.47 N.
A, a spark because if you touch something after rubbing your hand on carpet or something you get a spark
