One-dimensional motion can be plotted through the Cartesian plane which has a coordinates of (x,y). These coordinates are the abscissa and ordinates. Since, there are two coordinates, the answer to the second item is two.
The symbol that can be used to identify systems position is (x,y). Since this is one dimensional motion, it is possible that one of the two coordinates becomes zero.
According to the general rules and basic knowledge of physics, without any doubds I can say that a mole of red photons of wavelength 725 nm has [D] 165 kj of energy. I converted <span> a wavelength into energy in that way :
</span>

=

Answer:
0.96 m, upward
Explanation:



Initial velocity, u=0


Where 
Substitute the values





Hence,the block moves upward because displacement is positive.
They have a direct relationship. As mass increases, kinetic energy increases.
