the movement of individuals out of a population
the number of individual organisms that die in a population in a given year
the movement of individuals into a population
DONE
Answer:
the number of individual organisms born into a population in a given year - Birth rate
the movement of individuals out of a population - Emigration
the number of individual organisms that die in a population in a given year - Death rate
the movement of individuals into a population - Immigration
Explanation:
The birth rate describes the frequency of live births in a population. In contrast, the death rate, also called the mortality rate is the number of deaths in a population. They are usually reported as a number per 1000 people, per year.
Migration is the movement of organisms. Immigration is used to describe the act of organisms in a population into a new destination. Emigration is the act of organisms leaving their current population
Answer: the number of individual organisms born into a population in a given year - Birth rate
the movement of individuals out of a population - Emigration
the number of individual organisms that die in a population in a given year - Death rate
the movement of individuals into a population - Immigration

decrease 120 by 15%
Option (a) 77
(b) 87
(c) 92
(d) 95
(e) 102
Plz answer
Answer:
its e (102)
Explanation:
so, 120*15/100
Cancelling the zeros!
so,
12*15/10
= 6*15/5
=6*3/1
First we have to find 15% of 120
=6*3
=18
So, 15% of 120 is 18
now decreasing it from 120
120-18
=102
SO THE OPTION (e) IS CORRECT

Calculate the first and second velocities of the car with two washers attached to the pulley, using the formulas
v1 = 0.25 m / t1, and
v2 = 0.25 m / (t2 – t1)
where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. Record these velocities, to two decimal places, in Table E.
What is the first velocity of the car with two washers at the 0.25 meter mark?
m/s
What is the second velocity of the car with two washers at the 0.50 meter mark?
m/s
(1) The first velocity of the car with two washers at the 0.25 meter mark is 0.125 m/s.
(2) The second velocity of the car with two washers at the 0.5 meter mark is 0.25 m/s.
What is velocity?Velocity is the rate of change of displacement with time. The velocity of the cars depends on displacement and time of motion.
First velocity of the car at the 0.25 meter markThe first velocity is calculated as follows;
v1 = 0.25 m / t1
let t₁ = 2 s
v₁ = 0.25/2
v₁ = 0.125 m/s
Second velocity of the car at the 0.5 meter markv2 = 0.25 m / (t2 – t1)
let t₂ = 3 s
v₂ = 0.25(3 - 2)
v₂ = 0.25 m/s
