Answer:
I /
= 1.48
, The correct answer is d
Explanation:
the moment of inertia is given by
I = ∫ r² dm
For figures with symmetry it is tabulated. In the case of a thin variation, the moment of inertia with respect to its center of mass is
= 1/12 M L2
There is a widely used theorem, which is the parallel axis theorem, where the moment of inertia of any parallel axis, is the moment of mass inertia plus the moment of inertia of the body taken as a particle
I = + M D²
Let's put these expressions to our case.
As the bar is one meter long its center of mass that this Enel midpoint corresponds to
= 1/12 m L²
= 1/12 m 1.00²
= 8.33 10⁻² m
Let's use the parallel axes theorem for the axis that passes through x = 30 cm. The distance from the enrode masses to the axis is
D = 
- 0.30
D = 0.50 - 0.30 = 0.20 m
I = + m D²
I = 8.33 10⁻² m + m 0.2²
I = (8.33 10⁻² + 4 10⁻²) m
I = 12.33 10⁻² m
The relationship between these two moments of inertia
I / = 12.333 10⁻² / 8.333 10⁻²
I / = 1.48
The correct answer is d
Answer:
Explanation:
Assuming we have to find
Find the angle theta to the first minimum from the center of the central maximum (Expressing answer in terms of λ and a.):
a= avg separation between the building.
λ = wavelength
for single slit diffraction we have
a sinθ =nλ
for the first minimum n=1
a sinθ =λ
therefore,
possible car wrecks and harsh injuries and also distractions
Answer:
250 m
Explanation:
Given :
Initial velocity, u = 0
Acceleration, a = 5 m/s2
Time elapsed is t = 10 seconds
The distance traveled in 10 seconds by the particle when accelerating at 5 m/s2 is given by,
Putting the values,
x = 250 m
The particle moved 250 m in 10 seconds
