Answer:
add 15 to 36 which is 51 then divide 51 by 3 to get x by itself which is 17
For problems that involve an object accelerating along an inclined
plane, the weight can be used to determine the x and y force component that
causes the motion by using the formula:
The force component along the x direction is equal to weight
of the object multiplies by sin of angle of inclination of the ramp.
Fx=wsin(a). while force component along the y direction is equal to weight of
the object multiplies by cos of angle of inclination of the ramp, Fy = wcos(a).
atomic mass of carbon is C = 12 g/mol
atomic mass of hydrogen is H = 1 g/mol
now number of carbon atoms
Similarly the number of hydrogen atoms are
so Carbon atom and hydrogen atom must be in ratio of 10:30
so the ratio is 1:3
now the empirical formula is always in simplest form
