Answer: The potential difference between the plates = 0.4061V
Explanation:
Given that the
Electric field strength E = 155 N/C
Distance d = 0.00262 m
From the definition of electric field strength, is the ratio of potential difference V to the distance between the plates. That is
E = V/d
Substitute E and d into the above formula
155 = V/0.00262
Cross multiply
V = 155 × 0.00262
V = 0.4061 V
The potential difference between the plates is 0.4061 V
Magnesium chloride is your answer
The momentum of the car is 4.4x10^3 kg•m/sec
Answer:
The force is 15N
Explanation:
The formula is Force= mass × velocity.
From the question mass is 5kg, velocity is 3m/s.
F= 5×3
F= 15Newton.
Therefore the force is 15N.
