During one year a population of blue jays has zero population growth. which must be true about the blue jay population at the end of the year compared to the beginning of the year?

Hello there!

the fact that the population has zero population growth over a year means that, if at the start of the year the population was X, at the end of the year the population, Y, can't be bigger than X.

Then the relation between the population at the end of the year, Y, and the start of the year, X, is:

Y ≥ X

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
