Explanation:
option A is the correct answer, if the gravitational acceleration is taken 10m/s²(rounding of 9.8/ms²).
hope this helps you.
You got the formulas on the sheet on the top :) So just use those, exchanging v (as in velocity, expressed in m/s) and the d (in meters) and t (in seconds). Hope you will manage it.
Answer:
The African plate is splitting apart to form two separate plates. The African plate is colliding with the Arabian plate.

Answer:
3 mA.
Explanation:
The following data were obtained from the question:
Resistor (R) = 500 Ω
Potential difference (V) = 1.5 V
Current (I) =.?
Using the ohm's law equation, we can obtain the current as follow:
V = IR
1.5 = I x 500
Divide both side by 500
I = 1.5 / 500
I = 3×10¯³ A.
Therefore, the current in the circuit is 3×10¯³ A.
Finally, we shall convert 3×10¯³ A to milliampere (mA).
This can be obtained as follow:
Recall:
1 A = 1000 mA
Therefore,
3×10¯³ A = 3×10¯³ × 1000 = 3 mA
Therefore, 3×10¯³ A is equivalent to 3 mA.
Thus, the current in mA flowing through the circuit is 3 mA.
The amount of extra electrons present on the negative surface is

Distance =1.6 cm
Side = 24 cm
Electric field = 18000 N/C
Calculating the capacitance in the metal plates is necessary.
Using the capacitance formula

Putting the value
C = 8.85 x
x (24 x 
/1.6 x 
C = 0.318 x

<h3>Calculation of potential</h3>
V = Ed
V = 18000 x 1.6 x
V
V = 288 V
<h3>Calculation of charge</h3>
Q = CV
Q = 0.318 x
x 288
Q = 91.54 x
C
Charge on the both the plates
Q = +91.54 x 
Q = - 91.54 x 
Calculation of excess electrons on the negative surface:
n = q/e
n = 91.54 x
/ 1.6 x 
n = 57.2 x
electrons
Hence, the number of excess electrons on the negative surface is
