Answer:
A. Heat and Humidity
Explanation:
The hot, damp conditions on the forest floor allow for the rapid decomposition of dead plant material.
Answer:
This is the study of life
In my opinion, chloroplasts and mitochondria can't live outside the cell now because mitochondria ensure the energy for the cell and the chloroplasts is important for photosynthesis. Just my opinion.
Answer:
D
Explanation:
You can immediately eliminate B and C. So between A and D, D is the best answer.
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
