You are looking at some new FBD. You determine from it that there IS a (non-zero) net force acting on the object. (a) What MUST be true, for this and EVERY FBD, that tells you that there is a net force acting on it? (In other word, no “special cases” where say there is only one force; your answer must apply to each and every FBD with a net force)”

(b) Let’s say there is a net force to the right. What, if anything, can you conclude about the MOTION of the object, in the VERTICAL direction?
FBD means free body diagram.

Which expression allows you to determine the mechanical advantage of an inclined plane? a. height of plane / input force b. length of plane / input force c. length of plane / height of plane d. height of plane / length of plane

Any color picture tube and electric field exerts a net force of magnitude 1.68x 10^-13 n on an electron the rest mass of an electron is 9.11 x 10^-13 what is the electron acceleration?

Glass is transparent to visibile light under normal conditions; however, at extremely high intensities, glass will absorb most of the light incident upon it. this works through a process known as multiphoton absorption. in this process, several photons are absorbed at the same time. if very intense light whose photons carry 2ev of energy is shined onto a material with a band gap of 4ev, that light can be absorbed through two-photon absorption, because two photons have the right amount of energy to bridge the band gap. what is the minimum number of photons of 800-nm light that are needed to equal or exceed the band gap of fused silica glass
