Will give Brainliest and Thanks! (Worth 30 points!) Make an Electromagnetic Spectrum journal with three entries.
(Be sure to include the type of Electromagnetic Spectrum, a picture of something that uses Electromagnetic Spectrum, and a brief description explaining how the thing uses the Electromagnetic Spectrum.)

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

Find the momentum for a 2.6-kg brick parachuting straight downward at a constant speed of 8.4 m/s .

If jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, is being done.
