Hi Mandy!
Question - Momentum is a measure of the _ of an object.
Answer - motion
Why - Momentum is just another word for motion.
Hope this Helps :)
Answer:
Momentum = 750 Kgm/s
Explanation:
Given the following data;
Mass = 10 kg
Velocity = 75 m/s
To find the momentum;
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
Substituting into the formula, we have;
Momentum = 10 * 75
Momentum = 750 Kgm/s
If the sound source is approaching you, the frequency you hear is higher than the real frequency of by the sound. How much higher depends on how fast the source is approaching. If the source's speed is constant, then the frequency you hear is constant ... higher, but not increasing.
