Alfisols can be found in humid areas and semiarid areas. They are formed in forest and savanna vegetation. They are very fertile and productive soils. These soils contains high concentrations of nutrient that are cations like calcium, magnesium, potassium and sodium.
Answer:
Explanation:
a )
Work done by force = change in kinetic energy
F x s = ( vf² - vi² ) / 2m
F = ( vf² - vi² ) / 2ms
acceleration = ( vf² - vi² ) / 2m²s
b )
F = ( vf² - vi² ) / 2ms [ calculated above ]
c )
Work done by force
= change in kinetic energy
= ( vf² - vi² ) / 2m
Answer:the paper clip will be attracted to the magnet
Explanation:
Answer:
899752.13598 N
Explanation:
p = Pressure on the plate = 
A = Area = 
F = Force on the region
When force is divided by area we get pressure
Force is exerted by the atmosphere on a disk-shaped region is 899752.13598 N
Answer:
look at the explanation
Explanation:
This pith-ball electroscope is used to detect the presence of a static electricity charge. The two lightweight “pith” balls suspended from the strings are attracted to objects with a static electric charge. The pith balls can also be charged by touching them to an object with a static electric charge.
