1. The radius of Earth is 6.40*10^ 3 km The moon is about 3.84*10^ 5 km away from Earth and has a diameter of 3475 km. The Pacific Ocean surface, whic can be considered a convex mirror, forms a virtual image of the moon What is the diameter of that image ?

Global warming was a major concern some people do not care global warming is fake it is not real the percentage of it happening  is slight 

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j
