Answer:
Weight of an object = 225 newtons
Explanation:
Given:
Mass = 60 kilograms
Acceleration due to gravity = 3.75 m/s²
Find:
Weight of an object
Computation:
Weight of an object = Mass x Acceleration due to gravity
Weight of an object = 60 x 3.75
Weight of an object = 225 newtons
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!!!
The pressure in the balloon increases.
Answer:
9.6 m/s
Explanation:
Equation is v=d/t so plug 120m to d (distance) and 12.5 sec to t (time).
v=120/12.5
v=9.6 meters per second
