When light of wavelength 190 nm falls on a carbon surface, electrons having a maximum kinetic energy of 1.53 eV are emitted. Find values for the following. (a) the work function of carbon eV
(b) the cutoff wavelength nm
(c) the frequency corresponding to the cutoff wavelength Hz

more than, less

less than, more

it would be c. predictability

in most common fires, oxygen is needed for an oxidation reaction to takes place. the combination of oxygen with any element as fuel can create fire and combustion will occur especially if wood, light materials and other combustible things are combine with oxygen.

the moving of the box is a result of centripetal force. think of that  as a car or a truck in this case creates a turn, the force of friction performing upon the turned wheels of the car runs centripetal force obligatory for circular motion for the things inside it.
