Answer:
27 . 10^-7 or 27/1000
Explanation:
We use the Coulomb Law
k = Coloumb Constant
q1 and q2 are the charges
d is the distance between the spheres
Answer:
They are very distant.
Explanation:
With relativistic red shifts that take into account dilation of space-time, as Einstein predicted.
<span>When two electrical charges, of opposite sign and equal
magnitude, are separated by a distance, a dipole is established. The size of a
dipole is measured by its dipole moment</span><span> . Dip</span>ole moment is measured in Debye units, which is equal to the
distance between the charges multiplied by the charge
<span>Dipolemoment 'D' = e x d
where e= charge and d= distance by which charge is separated. </span><span>
In this case e = charge on electron = 1.6 x10^-19 C</span>
D = 1.6 x10^-19 C (
1x10^-10 m) =1.6x10^-29 Cm
The force exerted on the board by the karate master given the data is -4500 N
<h3>Data obtained from the question </h3>
- Initial velocity (u) = 10 m/s
- Final velocity (v) = 1 m/s
- Time (t) = 0.002 s
- Mass (m) = 1 Kg
- Force (F) = ?
<h3>How to determine the force</h3>
The force exerted can be obtained as illustrated below:
F = m(v - u) / t
F = 1 (1 - 10) / 0.002
F = (1 × -9) / 0.002
F = -4500 N
