See Answer →A small satellite is in a circular orbit around a planet at a distance of 4.0 x 10 8 m from the centre of the planet. The orbital speed of the satellite is 200 ms-1 What is the mass of the planet?
See Answer →A block of mass 5.0 kg starts from rest and slides down a surface which corresponds to a quarter of a circle of 3.0 m radius. (i) If the curved surface is smooth, find the speed at the bottom. (ii) If the speed at the bottom is 2.0 ms-1, calculate the energy dissipated due to friction in the descent. (iii) After the block reaches the horizontal with a speed of 2.0 ms-1it slides to a stop in a distance of 1.5 m. calculate the frictional force acting on the horizontal surface. Take g= 10 ms
See Answer →Heinz Moral Dilemma modified from Kohlberg, Lawrence (1981). Essays on Moral Development, Vol. I: The Philosophy of Moral Development. San Francisco, CA: Harper & Row.
A woman was near death from a very bad disease, a special kind of cancer. There was one drug that the doctors thought might save her. It was a form of radium that a druggist in the same town had recently discovered. The drug was expensive to make, but the druggist was charging ten times what the drug cost him to make. He paid $200 for the radium and charged $2,000 for a small dose of the drug. The sick woman's husband, Heinz, went to everyone he knew to borrow the money, but he could get together only $500. He told the druggist that his wife was dying and asked him to sell it cheaper or let him pay later. But the druggist said, "No, I discovered the drug and I'm going to make money from it." Heinz got desperate and broke into the man's store to steal the drug for his wife. Was Heinz right or wrong to steal the drug? Explain your answer.
