Answer:
Force,
Explanation:
There are two positive charges, 2 C and 5 C, separated by a distance of 20 cm in a vacuum. What is the value of the modulus of the electrostatic force between them?
We have,
Charge on object 1, q₁ = 2 C
Charge on object 2, q₂ = 5 C
Distance between charges, r = 20 cm = 0.02 m
The electric force between two charges is given by the formula as follows :
Plugging all the values we get :
So, the electric force between two charges is .
Answer: water
The light reactions of noncyclic photophosphorylation takes place in the chloroplast.
The light energy is converted to chemical energy to produce both ATP and NADPH,
which act as energy-transfer molecules in the light-independent reactions of
the Calvin cycle. The addition of phosphate due to synthesizing of ATP by cells
results to photophosphorylation.
Moreover, <span>the electrons from water replenish chlorophyll molecules that
have given up electrons by photolysis. The two electrons from the water
molecule are kept in photosystem II, while the 2H+ and 1/2O2 are
left out for further use.</span>

Answer: When a car is struck by lightning, the resulting electric field inside the car is zero.
Explanation:
B. Sonar I had the same question what a coincidence but I had a book about it so here's your answer
Let's calculate the angle between two spots, 0.5 cm apart,
that are 10m away from you.
1 m = 100 cm
10m = 1,000 cm
The angle between the two spots is very very close to the angle
whose tangent is
0.5cm/1,000cm = 0.0005 .
That angle is tan⁻¹(0.0005) = 0.0005 radian = 0.029 degree .
Matilda is looking at two stars that appear to be 0.001 radian apart.
That's (0.001 / 0.0005) = 2 = TWICE as far apart as Arthur can distinguish.
As long as Arthur and Matilda are on the same planet while looking at
these two stars ... or as long as they're even in the same solar system ...
Arthur will have no trouble separating them.
