Neither do.beacuse diffusion occurs due the random movement a substance's particals move from a higher concentration to a lower concentration down the concentration gradient.On the other hand osmosis is the movement of water molecules from a high water potential to a low water potential through a partially permeable membrane.thus no energy is required for them to do so.Active transport is a process that requires energy.
Answer:
Time period of the oscillation will be 0.695 sec
Explanation:
We have given mass attached to the string m = 0.350 kg
The spring is stretched by 0.120 m
So x = 0.120 m
We know that force is given by F = Kx
So mg = kx
k = 28.5833
Now time period is given by
So time period of the oscillation will be 0.695 sec
Is it 1314000 Or something
Answer: The wave can flip upside down.
Reflection is the bending of a wave when it cannot pass through. For example, plain mirrors which are flat, a ray of light hits the mirror and is reflected from the mirror since it cannot pass through
When reflection occurs the speed and frequency of the wave does not change but the wave is flipped upside down.
The speed does not change because speed is affected by the change in medium the frequency also remains the same since the energy of the wave does not change.
Id say A because the geocentric model is where the earth is at the center of the universe and all other planets, suns, stars, and moons are revolving around it
