Birth rate 10/1000 = +population
Death rate 9/1000 = -population
Immigration rate 3/1000 = +population
Emigration rate 7/1000 = -population
10/1000 - 9/1000 + 3/1000 - 7/1000= -3/1000
Growth rate = (-3/1000)(100%)= -0.3%
I think they are right! When one of the answers is, all of the above, that is usually the correct answer. pH is important to all living things.
A)mass of object, since density =mass/volume
Answer:
Explanation:
Change in gravitational energy of the ball = mgh
5 mutiply 10 multiply 1.7 = 85J
Potential energy at height = Kinetic energy at bottom
KE= 85J
Velocity
v=5.83m/s
