Answer:
Speed will be: 1.33ft/s
Explanation:
If ladder is 10 ft long and bottom is 8 ft from the wall then by Pythagoras theorem we can find the height of the wall where ladder touches. (before it started slipping)
thus 
Giving x= 6 ft. If the ladder is falling with a speed of 4ft/s it will take 1.5 seconds to cover the 6ft distance.
This shows that the bottom of ladder will travel from 8ft to 10 ft in 1.5 seconds. Thus covering 2 ft in 1.5 seconds making the speed to be:
v = S / t
v = 2 / 1.5
v = 1.33 ft/s

Answer:
Adsorption
Explanation:
Sidewalk cooking of egg is very popular in America. In summer people release fireworks in night sky and cook egg on the concrete sidewalk to check the level of temperature. When sunlight fall on the sidewalk most of the light is reflected back but some darker material adsorbs some photon, and when these photons are transferred to egg molecules it causes vibration among them and produce heat and cook egg.
Answer:
Cells
Explanation:
Non-living, it's atoms, but the smallest unit component that all living beings must have is the cell. In fact some living things can be just one cell. Every living being comes from cells, is made up of one or more cells, and cannot be considered a living organism without at least one.
