1 C / second= 1 amp. Therefore 5 C / 10 seconds= 0.5 amps
Answer:
1: 6.637e-13 N
2: 6.637e-09 N
3: 1.335e-08 N
4: 1.335e-08 N
5: 1.456e-06 N
6: 5.839e-07 N

I'd suggest double checking these if you can.
Explanation:
Each of these you can answer by plugging the numbers into the equation
G is the gravitational constant 6.673×10⁻¹¹ N m² / kg²
So the first one would be:
I'm not going to run through showing all calculations for the rest, as you're in a rush, so to whip through them
2: 6.637e-09 N
3: 1.335e-08 N
4: 1.335e-08 N
5: 1.456e-06 N
6: 5.839e-07 N
7: 6.673e-11
Pardon the lack of superscript, I just punched these into a python console to calculate them.
Answer:
0.8 N
Explanation:
From coulomb's law,
Formula:
F = kqq'/r²........................ Equation 1
Where F = Force of repulsion, k = coulomb's constant, q = first positive charge, q' = second positive charge, r = distance between the charge.
Given: q = 20 μC = 20×10⁻⁶ C, q' = 100 μC = 100×10⁻⁶ C, r = 150 cm = 1.5 m.
Constant: k = 9×10⁹ Nm²/C²
Substitute these values into equation 1
F = (20×10⁻⁶ )( 100×10⁻⁶)(9×10⁹)/1.5²
F = 1800×10⁻³/2.25
F = 1.8/2.25
F = 0.8 N
In the cytoplasm, molecules of Glucose are broken down to smaller molecules hence releasing mechanical energy during a process called called respiration or simply 'breathing process' in Physics realm.
