The concept of momentum tells us that it is equivalent to the product between the mass and the velocity of the object, that is to say that in general it can be written as
Where,
m = mass
v = Velocity
Our values are given as,
Replacing we have that,
Therefore the magniude of the momentum of the pitched baseball is 
Answer:
B The force that the floor of the elevator exerts on you and the force that you exert on the floor of the elevator
Explanation:
A. is incorrect because the force of gravity on you will always stays the same while the force of the elevator exerts on you changes as it takes you upward
B. is correct in accordance to Newton's 3rd law of action and reaction forces.
C. is incorrect because gravity force stays the same while the force that you exerts on the floor change as elevator moving upward.
D. is incorrect although it states Newton's 1st law. However there can still be pair of forces (part B) that could counter balance each other among other forces.
Only if the temperature of both samples is the same.
When the temperature of water changes, so does its density.
That means that more or less mass takes up the same volume,
and the same volume can get heavier or lighter.
Answer:
current, voltage
Explanation:
Resistors can both be connected in series and parallel configuration. when a resistor is connected serially, the same amount of current flows through each resistor element but the voltage across each resistor is determined by the magnitude of the resistance of each resistor. However, in a parallel connection, the same voltage is applied across each resistor but different current.
