Answer:
0.78m/s
Explanation:
Now the momentum ensued by the boy throwing the package Is
Mass of package × velocity of package =4.5×13=58.5m/s
This momentum initiated a momentum on the boy-boat system
Total mass of the boy-boat system is 24+53=75kg
Let the velocity ensued by the boat be v.
Hence from conservation of momentum
58.5 =75×v
v= 58.5/75= 0.78m/s
Impulse is just the product of mass and speed!
I = 1700 * 22.5 = 38,250 kg m/s
It does not have any special name for its units :(
Answer:
Shiny metals such as copper, silver, and gold are often used for decorative arts, jewelry, and coins.
Strong metals such as iron and metal alloys such as stainless steel are used to build structures, ships, and vehicles including cars, trains, and trucks.
Some metals have specific qualities that dictate their use. For example, copper is a good choice for wiring because it is particularly good at conducting electricity. Tungsten is used for the filaments of light bulbs because it glows white-hot without melting.
Nonmetals are plentiful and useful. These are among the most commonly used:
Oxygen, a gas, is absolutely essential to human life. Not only do we breathe it and use it for medical purposes, but we also use it as an important element in combustion.
Sulfur is valued for its medical properties and as an important ingredient in many chemical solutions. Sulfuric acid is an important tool for industry, used in batteries and manufacturing.
Chlorine is a powerful disinfectant. It is used to purify water for drinking and fill swimming pools.
