TWO forces, one of 12N and another or 24N act on body in such a way that they make an angle of 90° with each other. Find the resaltant of two forces.

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

Five structural isomers have the formula c6h14. where needed, draw the structure and give the iupac name of all five isomers.

If one object has a large redshift and another object has a small redshift, what can we conclude about these two objects?
