Answer:
Explanation:
Here mass density of rod is varying so we have to use the concept of integration to find mass and location of center of mass.
At any distance x from point A mass density
Lets take element mass at distance x
dm =λ dx
mass moment of inertia
So total moment of inertia
By putting the values
By integrating above we can find that
Now to find location of center mass
Now by integrating the above
So mass moment of inertia and location of center of mass
At the same time, however, you get less detail or less precision in a chart or graph than you do in the table. Imagine the difference between a table of sales figures for a ten-year period and a line graph for that same data. You get a better sense of the overall trend in the graph but not the precise dollar amount.
Social Classical is not a type of system.
True
From what Ive learned its like how you create your own hypothesis for a science experiment it may not work completely that way but you learn what didnt work and what does work
Answer:
Explanation:
15 ) Current_rms = Peak current / √2
= 6 / √2
= 4.24 A
Voltage_rms = 4.1 / √2
= 2.9 v
Average power = Voltage_rms x Current_rms
= 2.9 x 4.24
= 12.3 W
16 ) R₂ = 2R₁
Resistance of a material changes due to change in resistivity of material .
So resistivity ρ₂ will also be twice resistivity ρ₁
ρ₂ = 2ρ₁
2ρ₁ = ρ₁ ( 1 + .0035 t ) where t is rise in temperature.
1 = .0035 t
t = 1 / .0035
= 285.7 ⁰ C
