The water flows the fastest at the center.
This is due to the friction between the water and the sink/drain. The outer parts of the water that are in contact with the kitchen sink/drain experience a greater frictional force and slow down. Their slowing down also affects the layers of water molecules adjacent to them, thereby reducing their speed as well. The layer of water molecules least affected by the friction with the sink/drain is at the center, and so they are the ones that move the fastest.
Answer:
Explanation:
We have given that mass of electron 
It is given that initial velocity u=0 m/sec
Final velocity v = 
Distance S = 2.2 cm = 0.022 m
According to third law of motion 
Accelerating force F is given by F = ma
So accelerating force 
Answer:
17086
Explanation:
We are given that
Weight=5 kg
Distance of elbow from the weight=d=35 cm=
1 m=100 cm
g=
Work done each time on the weight=
20% means 0.20 of food energy=Work done each time on weight
Total work done in each time=
1 food calorie=4186 J
350 food calories=
Number of lift needed=
Hence, you must do 17086 arm raises to work off 350 food calories.
Answer:
Number of moles or volume
Explanation:
The number 2 on the right hand side signifies the number of moles of the product being formed.
It is necessary to include this number so as not to flout the law of conservation of mass when writing a chemical equation. The law of conservation of mass states that "matter is neither created nor destroyed during the course of a chemical reaction".
Since we must have equal number of matter on both sides of the expression, the coefficient number like the 2 seen in the expression is used to create a balance.
Here, 2 moles of HCl is formed which consists of 1 hydrogen atom and 1 chlorine atom.
