Answer:
the seed of the sound in the air is 343.3 m/s
Explanation:
The computation of the speed of the sound in the air is shown below:
As we know that
Speed = Distance divided by Time
So, here speed be 515m
And, the time is 1.50 second
So, the speed of the sound is
= 515m divided by 1.50 seconds
= 343.3 m/s
hence, the speed of the sound in the air is 343.3 m/s
The two factors that increase the size of a population are natality, which is the number of individuals that are added to the population over a period of time due to reproduction, and immigration, which is the migration of an individual into a place.
Answer:
3.8226 m/s
Explanation:
Momentum is conserved hence
equating momentum, p
p (before) = p (after)
0 = (m1v1)+(M2v2) but m2=2.77m where m and v are the masses and velocity respectively
0 = (mv1) +(2.77m)(1.38)
(mv1)=-(2.77m)(1.38)
(v1)=-(2.77)(1.38)
Solving v1
v1 = - 3.8226 m/s
= 3.8226 m/s, to the left
