Answer:
It is important to have more than one piece of evidence to make sure that the evidence is actually evidence. Or in other words, that the evidence is proven true. With only one piece of evidence, you can't be fully sure if calculations were correct, if the source was trustworthy, etc.
Multiple evidence is kinda like double checking math problems. If you don't do it, you can't be 100% certain the answer is correct.
Answer:
During the 3rd month the eyes, ears, nose, jaw and neck form along with the arms, legs, fingers, and toes.
Explanation:
Answer:
a .carbon dioxide(Co2) and water (H2O)
b. air and soil
Explanation:
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
The correct answer is the suprachiasmatic nucleus of the hypothalamus. The suprachiasmatic nucleus, as the name suggests, is the part of the hypothalamus located in right above above the optic chiasm. The main function of the suprachiasmatic nucleus is mainly responsible for the circadian rhythm of the body therefore the physiological activity on daily cycles.
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
