Which of the following is the author’s purpose for the second paragraph?

Which of the following is an example of a transmissible spongiform encephalopathy?

Hookworms penetrate the skin. They considered with gastrointestinal pathogens for which of the following reasons?

Express the equilibrium constant for the following reaction.4 Al(s) + 3 O2(g) ⇌ 2 Al2O3(s)

Consider the following reaction:CO2(g) + C(graphite) ⇌ 2 CO(g)A reaction mixture initially contains 0.56 atm CO2 and 0.32 atm CO. Determine the equilibrium pressure of CO if Kp for the reaction at this temperature is 2.25.

 (7 pts) Part d on Question 21.

(7 pts) Part c on Question 27.

A hollow ball of mass = [m] kg rolls without slipping down a ramp of height = [h] m, as pictured. At the bottom of the ramp, it rolls onto a frictionless table. It then has a perfectly elastic collision with a mass = [N] kg on a spring with spring constant = [k] N/m. (Q17 ans 2 pts, Q18 work 5 pts) What is the translational speed of the ball at the bottom of the ramp? (Q19, 7 pts) What is the velocity (speed and direction) of the ball directly after the collision. Velocities to the right will be positive. (Q20, 7 pts) What is the maximum compression of the spring after the collision? To continue, please give the translational speed of the ball at the bottom of the ramp (part a) in units of m/s.

A uniform meter stick is pivoted to rotate about a horizontal axis through the 25 cm mark on the stick. The stick is released from rest in a horizontal position. The moment of inertia of a uniform rod about an axis perpendicular to the rod and through the center of mass of the rod is given by Determine the magnitude of the initial angular acceleration of the stick.

A projectile is launched from the surface of the earth. What minimum launch speed is required if the projectile is to rise to a height of the radius of the earth above the surface? Disregard any dissipative effects of the atmosphere.
