Because he said the correct reason
Answer
given,
volume of the can = 360 mL = 360 x 10⁻⁶ m³
mass of the full can of pop = 0.369 kg
weight of the empty can = 0.153 N
temperature of water = 20⁰C
weight of the full can
W = m g
W = 0.369 x 9.8 = 3.616 N
Weight of the pop in can
w₂ = W - w₁
w₂ = 3.616 - 0.153
w₂ = 3.463 N
w₂ is weight of the liquid
Specific weight of the liquid
density of liquid
ρ = 979.59 Kg/m³
specific gravity of the fluid
SG = 0.979
Specific gravity of pop is equal to 0.979
Answer:
The right answer is (d)
Explanation:
The pressure drop in smooth pipes with laminar flow is determined by the resistance of the fluid to flow, which is controlled by Reynolds's number. At higher Re, higher drop. But in this case, we have no information about the speed of the fluid in each pipe, and the ipe is not related to that speed. therefore we don´t have the information to say that any of the other options are the right ones
Answer:
The 5 kHz signal will be less attenuated and the 10 kHz will be completely attenuated.
Low Pass Filter:
The purpose of a filter is to remove the undesired frequency components in a signal. A low-pass filter is one in which we allow low frequencies components to pass through it and block the higher frequency components. The frequency where it starts to attenuate the signal is called cut-off frequency.
Explanation:
We have a signal that contains 5 kHz and 10 kHz frequency component.
The cut-off frequency is 4 kHz which means the filter will attenuate the frequency components of 4 kHz or greater than that.
So, in theory both 5 kHz and 10 kHz frequency components will be attenuated.
But filters are not ideal and they usually have a little margin also called roll off which means it will allow some of the frequency components greater than cut-off frequency of 4 kHz.
Conclusion:
So to conclude, the 5 kHz signal will be less attenuated and the 10 kHz will be completely attenuated.
uhh , not all girls are like that. many of em these days are more career oriented and thats good i guess , so if anything ur just being judgy a f here.
