Select all that apply Which of the following are true regarding costs to defend intangible rights? (Select all that apply.) Multiple select question. Costs to defend intangibles should be capitalized, regardless of whether or not they are successful. If a defense is unsuccessful, the company should reduce the book value of the intangible to net realizable value. If the defense is unsuccessful, the legal costs should be expensed immediately.

In a disc that is rotating at a material point, its velocity from A to C with a constant acceleration of $a' = 2 \text{ m/s}^2$ with respect to the disk, when it reaches the full note C, becomes $v' = 5 \text{ m/s}$. The disk rotates with an angular velocity of 10 rad/s clockwise and an angular acceleration of 3 rad/s$^2$ counterclockwise. a) Find the velocity vector with respect to the ground at point C and the acceleration vector with respect to the ground at point C. b) Find the Coriolis force acting when the object passes exactly through the x - axis (point B). (Take $m = 0.5\text{kg}$)

- At equilibrium, which of the following things are always true? A) One or more of the reactants are completely consumed. B) The concentration(s) of one or more of the products is equal to the initial concentration of one of the reactants. C) The reaction rates of the forward reaction and the reverse reaction are equal. D A and B only E) A and C only Which of the following statements is TRUE? A) $K << 0$ implies the reaction will proceed in the reverse direction, with the rates of reaction now opposite in sign. B) When $K << 1$, the reverse reaction is favored, the forward reaction does not proceed to a large extent, so reaction is reactants-favored. C) When $K \approx 1$, the reaction is neither products-, nor reactants-favored, and the reaction completely stops reacting. D) When $K << 1$, the forward reaction is favored and goes essentially to completion, making the reaction product-favored. E) None of these are true.

by the arrangement of free electric charge within the conductor? [HINT: Think about what the total field within the conductor needs to be.] [2Q] Four identical particles of charge 5 µC are located at the corners of a square of side length 2 cm. What is the total electric field magnitude 10 cm above the center of the square? What is the magnitude of the electric force exerted on a -3 µC particle placed at that location? Topic 3: Voltage [3C] Two conductors at different voltage levels are brought into contact with each other. What happens to the voltage levels of the two conductors once electric current stops flowing between them? What happens to the electric potential energy of the system? [3Q] A 1 C particle is initially 1 meter away from a -1 C particle. Both particles have masses of 1 kg. What is the minimum speed that these two particles need to be moving away from each other in order to \"escape\" (meaning that their speeds when they are very far apart are zero). Assume that the initial speeds are equal magnitude and opposite in direction. Topic 4: Magnetism [4C] Two charged particles are traveling parallel to each other with the same speed. Will the magnetic forces between them attract or repel when they have (a) like charges and (b) opposite charge? [4Q] A particle moving 100,000 m/s has a circular arc trajectory of radius 8 cm in a uniform 2 T magnetic field. The particle moves perpendicularly to the field and has a charge of 2e. What is the particle's mass?
