Suppose that a person throws a ball upward at 15 m/s while standing on the edge of a cliff so that the ball can fall to the base of the cliff 50 m below. How long does it take the ball to reach the base of the cliff?
A dam is designed to withstand a pressure of 7840 lb/ft². Find the maximum depth of water that the dam could support.( A dam should not be built this tall—it should be designed to allow water to run over before reaching such dangerous condition.)

A process fluid is pumped from the bottom of one distillation column to another, using a centrifugal pump. The line is standard commercial steel pipe 75 mm internal diameter. From the column to the pump inlet, the line is 25 m long and contains 6 standard elbows and a fully open gate valve. From the pump outlet to the second column, the line is 250 m long and contains 10 standard elbows, 4 gate valves (operated fully open), and a flow-control valve. The fluid level in the first column is 4 m above the pump inlet. The feed point of the second column is 6 m above the pump inlet. The operating pressure in the first column is 1.05 bara and that of the second column 0.3 barg. Determine the operating point on the pump characteristic curve when the flow is such that the pressure drop across the control valve is 35 kN=m2. The physical properties of the fluid are density 875 kg=m3 , viscosity 1:46 mN m2s. Also,
A spring stretches 14 cm when an object weighing 28 N is hung from it . what is the spring constant.
What is the term given to the opposite of catalyst?
Suppose f : N → N is a function defined by ƒ(x) = a(x + b), where a, b E N. If f is a bijective function,
then find the value of a + b.
prove a --> ( b V c ) using contradiction method and combination of inference rules and equivalence laws from these premises : 1. a --> ( d V b ) 2. d --> c
Nikbakht has received an email from an unknown mailer offering an entry into a lottery. For a price, he can get a ticket that may pay a prize double the price. He buys 2 tickets. Unknown to him an unfair system determines a winner where losing is two times more likely than winning. In what ways is this lottery unfair? What is the expected value of this lottery? In your estimation how much has he paid?
