What is the relationship between birth rate death rate and growth rate?
Elenna [48]
the difference between the birth rate nad the death rate is known as growth rate. the growth rate is expresse in percentage ex:the presentrate of india is 1.93% per annum . According to 2001 census, birth rate was 26.1 per thousand and death rate was 8.7 per thousand . thus growth rate was 19.3 or 1.93% per year . births and death continue to take place at all places around the world . the differnce between total birth and total birth and total deaths in a populations over a period of time decides whether the population growthof the place is positive or negative. if the birth rate is higher than the death rate in a country, it means that the population will register a growth on the other hand, birth rate less than death rate indicates a shrinking population

Two identical masses are moving down a slope. One mass is traveling twice as fast as the other mass. how does the kinetic energy
nlexa [21]
The greater the speed of two identical masses, the greater the kinetic energy.  So, the mass that is traveling twice as fast as the other has much more kinetic energy.  The formula for kinetic energy is KE=m*v^2 (kinetic energy equals mass times velocity squared), and velocity is the same as speed in this case because it is squared.  So, the mass traveling twice as fast has 4 times the kinetic energy, because 2 squared=2*2=4.

Answer: The mass traveling twice as fast has four times the kinetic energy.
