Calculate the resistances using Equation 1-2 for each voltage / current pair you obtained from Step 5/(a thru d). Use the voltage measured by the DMM, not the voltage displayed by the LVPS! Are the calculated resistances constant, roughly constant, or widely varying? If not exactly constant, do they show a trend? Calculate the power released by the light bulb using Equation 1-3 for each voltage / current pair you obtained from Step 5/(a thru d). =(1-3) where P is power in watts [W], V is voltage in volts [V], and I is current in amps [A]. Only ~ 20% of its power is released as light; the rest is lost to heat.

attach the statements so i can answer : )

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
