The time between two successive meridian crossings of the vernal equinox (or any other fixed point in the celestial sphere) is called day and it is long.

Write the equation for momentum, first using symbols for the variables, then using words for the variables.

Photoelectrons with a maximum speed of 6.50 x 107 m/s are ejected from a surface in the presence of light with a frequency of 6.75 x 1014hz. if the mass of an electron is 9.10 x 10-31 kg, calculate in joules the maximum kinetic energy of a single electron. 3.84 x 10-15 j 1.92 x 10-15 j 5.92 x 10-23 j 3.07 x 10-16 j

If y gets smaller as x gets bigger and y have an relationship?
