Given:u=−10cm               f=20cm        (convex lens)

To find: v and image's nature.

Solution: From lens formula

v1−u1=f1

v1+101=201

v1=20−1

v=−20cm

And magnification = uv=2

Hence image formed is virtual, erect and magnified two times.

Answer 2

Answer:

The deflation that took place at the outset of the Great Depression was the most dramatic that the U.S. has ever experienced. Prices dropped an average of ten percent every year between the years of 1930 and 1933. In addition to a drop in prices, there was also a dramatic drop in output during the Great Depression.
