Answer:
The frequency what Steve will hear is option a) f'≅ 11kHz
Explanation:
f= 10 kHz
v= 340 m/s
vf= 30 m/s
vo= 0
f'= f * (v/ v- vf)
f'=10.96 kHz ≅ 11 kHz
Thank you for posting your question here at brainly. I think your question is incomplete. Below is the complete question, it can be found elsewhere:
What is the probability of finding an electron within one Bohr radius of the nucleus?<span>Consider an electron within the 1s orbital of a hydrogen atom. The normalized probability of finding the electron within a sphere of a radius R centered at the nucleus is given by 1-a0^2[a0^2-e^(-2R/a0)(a0^2+2a0R+2R2)]. Where a0 is the Bohr radius (for a hydrogen atom, a0 = 0.529 Å.). What is the probability of finding an electron within one Bohr radius of the nucleus? What is the probability of finding an electron of the hydrogen atom within a 2.30a0 radius of the hydrogen nucleus?
Below is the answer:

Answer:
She should braise it
Explanation:
Joan purchased a large, tough cut of beef. To make the meat more tender, she should braise it.
Braising begins with dry heat and ends with moist heat. At high temperatures, beef is seared in a heavy-bottomed Dutch oven to attain a caramelized crust. Then cover and finish cooking in a liquid at lower temperatures.
