Answer:
B) the change in momentum.
Explanation:
The impulse is defined as the product between the force applied on an object (F) and the duration of the collision (
):
(1)
We can rewrite the force by using Newton's second law, as the product between mass (m) and acceleration (a):
So, (1) becomes
Now we can also rewrite the acceleration as ratio between the change in velocity and change in time: 
. If we substitute into the previous equation, we find
And the quantity 
is equivalent to the change in momentum, 
.
Answer:
48 million people get sick, 128,000 are hospitalized, and 3,000 die
Explanation:
Higher pay for teachers means students do better When teachers get paid more, students do better. In one study, a 10% increase in teacher pay was estimated to produce a 5 to 10% increase in student performance. Teacher pay also has long-term benefits for students.
Answer:
A wave that has smaller amplitude than another carries less what
Waves that have smaller amplitude have less energy. the particles of the waves. rarefactions are far amplitude waves. Wavelength is the distance from one crest to the next crest or from one trough to the next trough.
Explanation:
Answer:
<u>
</u> is the centripetal acceleration.
Explanation:
As per given values
Radius of earth (r) = 6371000 m
The "international space station" is orbiting with a velocity (v) = 7667 m/s.
"Centripetal acceleration" is the acceleration is equal to "the square of the velocity" divided by "the radius of the circular path".
V = velocity of the orbit
R = radius of the earth + height of the space station
R = 6,371,000 + 408,000
R = 6779000 m
The direction of the centripetal acceleration is always inwards along the radius vector of the circular motion.
