The tilt of the earth's axis. As the earth faces a different direction the seasons change.
(average mass of an apple) x (average number of apples in a bag) .
The answer is exact.
here two forces are acting at different angles and we need to find its resultant
forces are given as
@125 degree
@200 degree
now in order to find its resultant we will find its components
here it is given as
Now net force in x and y direction is given as
so net force is given as
now the magnitude is given as
angle of the force is given as
so net resultant force is 917.13 N at 163.4 degree
