Answer:
Explanation:
Given that
L = 3 m
M = 2.4 kg
m=0.7 kg
r= L/2 = 1.5 m
The moment of inertia of rod about it center
The moment of inertia of point mass about center of rod
I'= mr² + mr²
So total moment of inertia
By putting the values
The electrostatic force between the two charges is
Explanation:
The electrostatic force between two charges is given by Coulomb's law:
where:
is the Coulomb's constant
are the two charges
r is the separation between the two charges
In this problem, we have the following data:
is the magnitude of the two charges, where
is the fundamental charge
is the separation between the two charges
Substutiting into the equation, we find the force:

Answer:
F = 1.58*10^{11} N
Explanation:
given data:
length of steel beam = 27 m
cross sectional area of rail = 35 cm
Degree celcius
change in length of steel beam is given as
m
Young's modulus is
F = 1.58*10^{11} N
Soil profile includes all the sections/ horizons of the vertical soil depth from top to bottom including the transitions from one horizon to another. A soil horizon is a distinct layer/section of soil with more or less the same texture. Therefore, a soil profile is made of soil horizons.
