Answer:
1 mole has 6.023× 10^23 particles
So, In 0.622 mole no of particles = 6.023× 0.622× 10^23
=3.74 × 10^23
Let
h=height of table= 1.25m
g=acceleration due to gravity= 9.8m/s^2
t=time taken=?
Solution
h =(vi)(t)+1/2(g)(t^2)
1.25=(0)(t)+1/2(9.8)(t^2)
t^2 = 0.255
t. = 0.5s
-45N because you add the side together and make it equal 0
Answer:
The volume of the cylinder is 
Explanation:
Given that,
The height of the cylinder is 13 cm
Radius of the cylinder is 4 cm
We need to find the volume of the cylinder. The formula that is used to find the volume of a cylinder is given by :

So, the volume of the cylinder is
