If the amplitude of a simple harmonic oscillator is doubled, by what factor does the total energy increase?

dybincka [34]

Answer:

c)by a factor of four

Explanation:

The total energy of a simple harmonic oscillator is given by

$E=\frac{1}{2}kA^2$

where

k is the spring constant of the oscillator

A is the amplitude of the motion

In this problem, the amplitude of the oscillator is doubled, so

A' = 2A

Therefore, the new total energy is

$E'=\frac{1}{2}k(2A)^2=4(\frac{1}{2}kA^2)=4E$

So, the total energy increases by a factor 4.

A fluid, with a density of rho = 1165 kg/m3, flows in a horizontal pipe. In one segment of the pipe the flow speed is v1 = 4.53

Elza [17]

Answer:

The pressure difference between two pipe is $1.01 \times 10^{4}$ Pa

Explanation:

Density $\rho = 1165$ $\frac{kg}{m^{3} }$

Speed in one pipe $v_{1} = 4.53$ $\frac{m}{s}$

Speed in second pipe $v_{2} = 1.77$ $\frac{m}{s}$

According to the bernoulli equation,

The pressure difference is given by,

$P = \frac{1}{2} \rho v^{2}$

$P_{2} - P_{1} = \frac{1}{2} \rho (v_{1}^{2} - v_{2}^{2} )$

$P_{2} - P_{1} = \frac{1}{2} \times 1165 \times[ (4.53)^{2}- (1.77)^{2}]$

$P_{2} - P_{1} = 10128.51$

$P_{2} - P_{1} = 1.01 \times 10^{4}$ Pa

Therefore, the pressure difference between two pipe is $1.01 \times 10^{4}$ Pa
