What is the magnitude of the electric field at a point 0.0055 m from a 0.0025
C charge?
Use E = kq and k = 9.00 x 10° N·m²/C2.
O A. 7.4 x 1011 N
O B. 4.1 x 10°N
O C. 2.0 x 1010 N
O D. 7.9 x 1012 N

If gases like carbon dioxide and methane make up less than 1% of the total atmosphere, why is it important for scientists to monitor changes in percentages of these gases?

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?

The experiment was repeated many years later but the gases were mixed in a different type of container. a white solid was obtained which was xenon fluoride. predict whether you think 1) krypton and 2) radon will react with fluorine. explain reasons for your predictions
