What is the wavelength of a wave with the frequency of 330 Hz and a speed of 343 m/s
user100 [1]

Answer:

The wavelength of a wave with the frequency of 330hz and a speed of 343m/s would be 1.04m

Explanation:

You can get the wavelength of a wave by dividing the speed of the wave by its frequency, which in this case would be:

343/300, which as a decimal number, it'd be 1.04.

I hope I helped you, and a "Brainliest" is always appreciated! ☺

Given that the electric potential is 7.3×10−2 V higher outside the cell than inside the cell, and that the cell membrane is 0.10
Pavel [41]

Answer:

Work to move on ion inside a cell = 1.168×10^-20J

Explanation:

Potential difference is a ratio of work done by a charge.

It is given as

◇V= Workdone ×charge= W/a

Workdone = V × q= (7.3×10^-2)×(1.6×10^-19)

W= 1.168×10^-20Joules

*** PLEASE HELP EVEN FOR JUST ONE OF THE QUESTION WOULD REALLY HELP ME***
kondaur [170]

The distance covered in one orbit is equal to the circumference of earth.

Given that radius of earth is 3959 miles.

Circumference of earth= 2πr = 2*3.14*3959 = 24875.13 miles

Speed is 26,000 miles per hour.

Since, Velocity= Distance/Time

Time= Distance/Velocity = 24875.13/26000

Time = 0.9567 hours

Therefore,

Average hour per orbit is 0.957 approximately.
