Density = mass/ volume (so here this is how you would solve the problem)
<span>D = 38.6 g/ 2 cm3 (first step)</span>
<span>D= 19.3 g/cm3 ( Do math and then you would get this)</span>

<span>Hope this helps!! :) </span>
If the impulse is 25 N-s, then so is the change in momentum.
The mass of the ball is extra, unneeded information.
Just to make sure, we can check out the units:
<u>Momentum</u> = (mass) x (speed) = <u>kg-meter / sec</u>
<u>Impulse</u> = (force) x (time) = (kg-meter / sec²) x (sec) = <u>kg-meter / sec</u>
It is a field of study that make direct use of phenomena that is "quantum-mechanincal", such as superposition and entanglement. It's used to perform operations on data
Answer:
speed is increasing.
this is because the graph has a positive slope (due to it going up ), if it were decreasing, the graph would be going down
It is gravity¿ what is the question?
