How much work is done in lifting a 50-n box at a height of 1.5m a. 75j b. 75j c. 33.3j d. 0.03n-m e 37.5j

Work done = M x g x h

M = Mass of the body in Kg

g = Acceleration due to gravity

h - height of displacement

Work done = (M x g) x h

= 50 N x 1.5 m

= 75 J

not too sure thinking it will always be directed towards the centre of the earth. could be wrong not sure

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
