1. the diagram below shows a periscope. mary is using it to look over a wall.

draw the path the light ray would take through the telescope. show the direction of light rays with arrows.

the answer is true. hope it .

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
