Answer:
air resistance, gravitational force
Answer:
400000
Explanation:
So first solve one part:
(3.25 * 10^5)
(3.25 * 100,000)
= 325000
Then solve the next part:
(7.5 * 10^4)
(7.5 * 10000)
= 75000
Now lastly, add the two answers:
325000 + 75000 = 400000
Therefore,
(3.25 x 10^5) + (7.5 x 10^4) = 400000
Im not sure if this is physics or mathematics. but if 300 msec then per minute this will equal to 300 X 60 sec =18000 m per minute
Hey there,
So first we need to know how much molecules are there in 4 grams of hydrogen right?
In one gram of hydrogen there are 6.0221415 multiplied by 10^25 molecules right?(this number is known as avagadors constant )
And to make one molecule of water u need two molecules of hydrogen and one of oxygen.
And oxygen is unlimited right?
So when we have 6.0221415 grams of hydrogen tow if these are required to make one water.
So divide that by two and you get 3.0110704 multiplied by 10^25.
So the answer is you can make the above number of water molecules.
Hope this helps!!!
To solve this exercise it is necessary to take into account the concepts related to Pressure depending on the Force and the Area.
The pressure is defined as
Where,
Our values are given as,
Where 
is the mass of the person and 
is mass of cycle. Therefore the total mass at the system is 105Kg.
For Newton's second law we have:
where a is the acceleration, in this case the same Gravitational acceleration.
We need to make two considerations, the first is to calculate the total weight and second to calculate the weight on each wheel (2), that is
Force in each wheel,
In this way we can now calculate the length based on the pressure, that is
Therefore each tire has 3.21cm
