Need calculate the change in temperature of the water in the calorimeter after each metal sample was added. record these values in table b of your student guide. what is the change in temperature for the water in the calorimeter after the aluminum wire was added? c what is the change in temperature for the water in the calorimeter after the steel wire was added? c what is the change in temperature for the water in the calorimeter after the lead pellets were added? c

1) 2.6 C

2) 1.5 C

3) 0.8 C

Explanation: I know this answer is late, but I want to help others that need the answer to this question. Have a wonderful day/night!

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.
