Answer:
D; The microscope and magnifying glass block out the light, which allows the naked eye to focus on the object.
Explanation:
This is to prevent chromatic abberation
The reason a tennis ball and a solid steel ball will accelerate at the same rate in the absence of air resistance is because the net force to mass ratio is the same for both objects.
<h3>
What is air resistance?</h3>
Air resistance is described as the forces that are in opposition to the relative motion of an object as it passes through the air.
The units for the force of air resistance are in Newtons (N).
Air resistance can be gotten by taking air density times the drag coefficient times area all over two, and then multiply by velocity squared.
So we can conclude that in the absence of air resistance, the horizontal velocity of the body is unaffected by any other external force as the only force which acts on the ball is gravity.

Explanation:
Spaceship A moves at 0.800 in the positive – direction, while spaceship B moves in the opposite direction at 0.750 (both speeds are measured relative to Earth). What is the velocity {A,B} of spaceship A relative to spaceship B
Answer:
the equilibrium constant is equal to 1 (i.e., the reactant and product concentrations are always equal).
Explanation:
ΔG is a symbol related to Gibbs free energy, which is a physical quantity related to thermodynamics. ΔG refers to the difference between the change in enthalpy (and sometimes entropy) and the temperature of a chemical reaction.
Gibbs free energy is very useful for measuring the work done between the reactants in a reaction. It is calculated using the formula: ΔG = change in enthalpy - (temperature x change in entropy).
The ΔG of a reaction would have a minimum value (zero), if the equilibrium constant is equal to 1 (that is, the concentrations of the reagent and the product are always equal).
