Dalton's Atomic Theory had several main points, which are variously grouped into five statements : 1) All matter is made of atoms. 2) Atoms of a given element are identical in size, mass and chemical properties. 3) Atoms of different elements have different masses and properties.
Answer:
The input force is the force that when you push down and the output force is the stable going into the paper.
Explanation:
I really hope this helps ;)
Answer:
C
Explanation:
For a uniformly distributed mass, the center of gravity is also the geometric center. For this shape, the center is at point C.
You should ask what type of technology he uses to track hurricanes!
You should also ask why is it important to improve hurricane forecasts!
Hope this gives you some ideas :)
Answer:
x = 2.37 cm
Explanation:
given,
density of oil = 923 kg/m³
height of the block = 4.81 cm
density of the block = 961 Kg/m³
density of water = 1000 Kg/m³
Let x be the depth of the block in the water.
now,
Weight of block will be acting downward.
Buoyancy force will be acting on the block because of the oil and water.
At equilibrium position both weight and the buoyant force will balance.
x = 0.0237 m
x = 2.37 cm
Hence, the block is 2.37 cm in the water.
