The wave formula is shown below. Check all boxes that are correct.

1. Wave speed is inversely related to the product of wavelength and frequency.

2. Wavelength has an inverse relationship with wave frequency when wave speed remains constant.

3. Wave speed is directly related to the product of wavelength and frequency.

4. Frequency has a direct relationship to wavelength when speed remains constant.

5. Wavelength and frequency are not related to wave speed.

Two red blood cells each have a mass of 9.0 multiply.gif 10-14 kg and carry a negative charge spread uniformly over their surfaces. the repulsion arising from the excess charge prevents the cells from clumping together. one cell carries −2.50 pc of charge and the other −3.10 pc, and each cell can be modeled as a sphere 7.5 μm in diameter. (a) what speed would they need when very far away from each other to get close enough to just touch? assume that there is no viscous drag from any of the surrounding liquid. answer is: 321 m/s how do i find this (b) what is the maximum acceleration of the cells in part (a)? answer is: 1.38e+10 m/s2 how did they find this answer
