Answer:
1300 Hz
Explanation:
f' = Actual frequency = 4.8 MHz
f = Observed frequency
= Relative velocity of blood = 0.21 m/s
v = Velocity of ultrasound = 1540 m/s
From the Doppler effect formula we have
Frequency shift is given by
The frequency shift in the sound is 1300 Hz
To summarise the findings, in 2012, there is a significant and positive relationship between higher education level and income (i.e., higher education qualifications lead to higher income). ... Next, we examine the incomes of between bachelor's degree and graduate degree holders.
Answer:
Charge on B is 12 uC.
Explanation:
Initial charge on A = 32 uC
Initial charge on B and C = 0
Now A touches to B, so the charge on A and B both is
q = (32 + 0) / 2 = 16 uC
Now A touches to C, so the charge on A and C both is
q' = (16 + 0) / 2 = 8 uC
Now again A touches to B so the charge on B is
q''= (8 + 16) / 2 = 12 uC
<span>The question is asking us to define the sentence ""I want to run, to skip, and to jump". This is a parallel construction, which means that the three parts ("to run", "to skip" and "to jump" are in the same kind of construction - to <verb>. It could be considered comma splice, but a comma splice would rather be the case if there were different subjects : for example in "I want to run, she wants to skip". </span>
