The drawing shows two identical systems of objects; each consists of the same three small balls connected by massless rods. In both systems the axis is perpendicular to the page, but it is located at a different place, as shown. The same force of magnitude F is applied to the same ball in each system (see the drawing). The masses of the balls are m₁ = 9.4 kg, m2 = 6.8 kg, and m3 = 7.1 kg. The magnitude of the force is F = 476 N. (a) For each of the two systems, determine the moment of inertia about the given axis of rotation. (b) Calculate the torque (magnitude and direction) acting on each system. (c) Both systems start from rest, and the direction of the force moves with the system and always points along the 4.00-m rod. What is the angular velocity of each system after 5.79 s?

Let P2 = {a0 + a1x + a2x^2 | a0, a1, a2 ∈ R} be the set of all polynomials of degree 2 or less and let M2×2 be the set of 2 × 2 matrices over R. Then P2 and M2×2 are vector spaces over R in the usual way. Let h : M2×2 → P be defined by [a b c d ] → (b + c)x + (a + c)x^2 (a) Prove that h is a linear transformation. Find the following for h: (b) range space, (c) null space, (d) rank

Consider an American-style call option on Pearl Enterprises stock. If the market for Pearl Enterprises's call options has historically only traded options with one-month expirations but suddenly the only call options being traded have three-month expirations, what would you expect to happen to the equilibrium price (premium) and quantity associated with the American-style call option? The price of the American-style call option would increase. The price of the American-style call option would decrease. Consider an American-style put option on Pinchete Enterprises stock. If the market for Pinchete Enterprises's put options has historically only traded options with three-month expirations, but suddenly the only put options being traded have one-month expirations, what would you expect to happen to the price of the American-style put option? The price of the American-style put option would increase. The price of the American-style put option would decrease.

What is meant by semi-conservative replication? Question 4 options: This means that each new molecule of RNA contains two strands of the original parent RNA and two strands of new, complementary RNA. Each new RNA molecule thus contains a whole of the original molecule. This means that each new molecule of RNA contains one strand of the original parent RNA and one strand of new, complementary RNA. Each new RNA molecule thus contains half of the original molecule. This means that each new molecule of DNA contains two strands of the original parent DNA and two strands of new, complementary DNA. Each new DNA molecule thus contains a whole of the original molecule. This means that each new molecule of DNA contains one strand of the original parent DNA and one strand of new, complementary DNA.
