<span>Stainless steel is a metal alloy
that made up mainly of carbon and chromium. In combination
with low carbon contents, chromium is highly reactive element that imparts
remarkable resistance to corrosion and heat.</span>
Moreover, stainless
steel is mixed up with sufficient nickel, which is an essential allying element
in the series of stainless steel grades. Other components are manganese,
molybdenum, silicon, titanium, aluminum, niobium, copper, nitrogen, and sulfur.
If the pebble sinks it has a greater density an the twig has a lighter density
just like water and oil. water sits on top of oil because of their density
A vector has a size and a direction. The size is called the magnitude of the vector.
Answer:
a. Weight of Object in Water = 20 N
b. Up thrust = 20 N
c. Weight of Water Displaced = 20 N
Explanation:
a.
The weight of the object remains same in the water as well. Because, the same force of gravity is acting there as well. Hence,
<u>Weight of Object in Water = 20 N</u>
<u></u>
b.
Since, the object floats on the water. Therefore, according to Archimedes' principle the up thrust force acting on the object must be equal to the weight of object:
Up thrust = Weight of object
<u>Up thrust = 20 N</u>
<u></u>
c.
From Archimedes' Principle, we know that the up thrust or the Buoyant force is equal to the weight of the water displaced by the object. therefore:
Weight of Water Displaced = Up thrust
<u>Weight of Water Displaced = 20 N</u>
