So we want to know what do electric field lines show except strength of the electric field. Electric field lines are lines that show us the field strength and the DIRECTION of the electric field. If the lines point away from the charge that is producing the lines, the charge is positive, and if the lines point towards the charge that is producing them that charge is negative.
Answer: The formula of Newtons second law of motion is F=MA so therefore it would be written like this Force = Mass X Acceleration
F = 5 x 2
F = 10 N
The answer is b because the sun's surface temperature is 5,778 K.
We know that impulse is simply the product of Force and time:
Impulse = Force * time
Since Force has a unit of Newton or kg m/s^2 and time is in
seconds, therefore impulse can have units as:
N s
or
<span>kg m/s</span>
Sodium (Na) is a Alkali metal so that's the answer
