What is the sum of all coefficients of the polynomial? f(x)= (3x^3 - 3x - 1)^38 * (2x+1)^4 * (x^4 - 3x^2 + 5x - 2)^77
I think term 55 but I am not sure what that proves or if it shows you the answer?
X rays bombarding heavy atoms can be used to eject electrons from the 1s shell in atoms; indeed, this is the starting point for Moseleys experiments. Estimate the maximum wavelength of pho- tons required to eject an electron from the 1s shell of copper, for which Z = 29....
A 100-watt bulb becomes warm and glows brightly enough to light a small room. On the other hand, a 100-watt laser can cut holes in steel and would not be effective at lighting a small room. What is true about the light coming from these two sources that accounts for these dif-...

A 2.25kg book is dropped from a height of 2.5m what is the acceleration?
Two ice skaters, Daniel (mass 70.0kg ) and Rebecca (mass 45.0kg ), are practicing. Daniel stops to tie his shoelace and, while at rest, is struck by Rebecca, who is moving at 14.0m/s before she collides with him. After the collision, Rebecca has a velocity of magnitude 6.00m/s...
