Answer:
The ratio of the pressure at the top to the pressure at the bottom is
Explanation:
Given that,
Number of molecules
Mass
Temperature = 300 K
Height
We need to calculate the ratio of the pressure at the top to the pressure at the bottom
Using barometric formula
Where, m = mass
g = acceleration due to gravity
h = height
k = Boltzmann constant
T = temperature
Put the value in to the formula
Hence, The ratio of the pressure at the top to the pressure at the bottom is
Answer with Explanation:
We are given that
Charge on alpha particle=q=2 e=
1 e=
Mass of alpha particle=m=
Potential difference,V=
Magnetic field,B=3.49 T
a.Speed of alpha particle=v=
By using the formula
b.Magnetic force,F
F=
c.Radius of circular path, r=
r=0.084 m
Answer:
The right option is C. i.e L
Explanation:
Dimension of a quantity is the collection of the indexes of each of the fundamental quantities contained in it.
Therefore, to get the dimension of A in the equation
X=Asin(2(pi)ft)
Making A the subject of the formula
A = X / (sin(2(pi)ft)
Since sin(2(pi)ft which is a trigonometric function does not have a dimension
A = L
The dimension of A is L
Sound intensity = 1/(r^2)
That is Sound intensity is indirectly proportional to the distance. Therefore, sound becomes 9 times less intense.
