What happens to the kinetic energy of a snowball as it rolls across the lawn and gains mass.

Answers

Kinetic energy of a snowball will increase as it rolls across the lawn and gains mass. We already know that Kinetic energy is directly proportional to speed. We can express kinetic energy by the formula 
Kinetic energy = 1/2 mv^2
Now as the mass increases and the velocity remains constant, the kinetic energy of the snowball is bound to increase. I hope the explanation has helped you.

Answer:

Kinetic Energy Increases

After mitosis each identical daughter cell has a complete set of what? Is it chromosomes or organelles ?

Answers

I believe that the answer's chromosomes. 

I say that because mitosis is used to produce daughter cells that are pretty much genetically identical to their parent cells. The cell then replicates its chromosomes, and then it splits the copied chromosomes equally to make sure that each daughter cell has a full set.
I believe the answer is chromosomes .

After studying about recycling, members of Miguel’sbiology class investigated the effect of various

recycled products on plant growth. Miguel’s lab

group compared the effect of different aged grass

compost on bean plants. Because decomposition is

necessary for release of nutrients, the group

hypothesized that older grass compost would produce

taller bean plants. Four flats containing the same

species of bean plants (25 plants/flat) were grown for

5 days. The plants were then fertilized with compost

as follows: (a) Flat A: 450 grams of two-month-old

compost; (b) Flat B: 450 grams of four-month-old

compost; (c) Flat C: 450 grams of six-month-old

compost; (d) Flat D: 0 grams of compost. The flats

of beans were planted in the same type of soil. The

plants received the same amount of sunlight and

water each day. At the end of 30 days, the group

recorded the height of the plants in centimeters. What is the flaw in this experiment?
