Answer:
The magnitude of the electric force on a protein with this charge is 
Explanation:
Given that,
Electric field = 1500 N/C
Charge = 30 e
We need to calculate the magnitude of the electric force on a protein with this charge
Using formula of electrostatic force

Where, F = force
E = electric field
q = charge
Put the value into the formula


Hence, The magnitude of the electric force on a protein with this charge is 
As you move closer to the star, it appears brighter. Brighter magnitudes are lower numbers, so the star's apparent magnitude would decrease.
Answer:
A: The kinetic energy of the two vehicles is transferred to potential energy when it stops.
B: The more mass an object has the more kinetic energy it will have.
Explanation:
This may be the right answer for your question but if it isn't my bad.
