Using the kinematic equation:
Vf=Vi+at then plug the values in.
Vi=0 m/s (Because the ball is dropped)
t=3 s.
a=9.81 m/s=g
Vf=0+3*9.81;
Vf=29.43 m/s
Democritus was a Greek philosopher who lived between 470-380 B.C. He developed the concept of the 'atom', Greek for 'indivisible'. Democritus believed that everything in the universe was made up of atoms, which were microscopic and indestructible. Democritus had many remarkable insights for his time.
Bacteria get rid of waste through their semi-permeable membrane by diffusion. The waste is pushed out of the organism in the form of liquid or gas. The waste released by bacteria is usually toxic and is what makes people sick.
Answer:
4 m/s or 4 meters per second.
Explanation:
In order to calculate the speed of wave, you multiply the wavelength in meters and the frequency of the Wave in Hertz. 2 times 2 equals 4. The wave speed is always in m/s considering that the wavelength is also in meters.
Answer:
False is the correct answer.
It is considered more of a chemical change because all of the cells inside the plant decompose (change chemicaly)
