First, let's find the angle of inclination using the tangent function.
sin θ = opposite/hypotenuse = 1 m/2 m
θ = 30°
Assuming the ramp is frictionless, the force balance is:
F = mgsinθ = ma
Cancelling out m,
a = gsinθ = (9.81 m/s²)(sin 30°) = 4.905 m/s²
Using the equation for rectilinear motion at constant acceleration,
x = v₀t + 0.5at²
2 m = (6 m/s)(t) + 0.5(4.905 m/s²)(t²)
Solving for tm
t = 0.297 seconds
Using the equation for acceleration:
a = (v - v₀)/t
4.905 m/s² = (v - 6 m/s)/0.297 s
Solving for v,
v = 7.46 m/s

In terms of cell division, normal cells differ from cancer cells in at least four ways. Normal cells require external growth factors to divide. When synthesis of these growth factors is inhibited by normal cell regulation, the cells stop dividing.
Answer:
D
Explanation:
A: to create sex cells of reproduction.
This is the purpose of meiosis: a cell division process. It creates gametes, or sperm and eggs.
B. to provide the cells with food
This would be eating for animals, or photosynthesis for plants. When animals eat, it provides their cells with food. When plants photosynthesize, they create their own food in the form of glucose.
C. To give the cell energy
This would be cellular respiration. It turns food and glucose into usable energy called ATP.
D.
This is the correct choice. Mitosis is cell division, which means it creates new cells. This allows organisms to grow and repair.
