Julia is in a car with her father. The car is undergoing centripetal acceleration. What is happening to the car? A. The car is slowing down. B. The car is stopping suddenly. C. The car is changing direction and speeding up. D. The car is changing direction at a constant speed

Penny says that there is no gravitational force between dust particles because they have too little mass. Ella says that dust particles do pull on each other gravitationally and would move toward each other if they were in outer space instead of in air. Who has the better argument, and why? F. Penny, because objects with only a little mass are not affected by gravity. G. Penny, because any force on a dust particle would change its motion. H. Ella, because any two objects exert a gravitational force on each other. I. Ella, because objects with smaller mass have more gravity acting on them

Identify the sample, and suggest a population from which it was selected. Then classify the sample as simple, stratified, or systematic. Explain your reasoning. Greg divides his rookie baseball cards by teams. Then he randomly selects cards and records the players' RBIs.

Determine the oxidation number for each element in the following compounds. $H_3 BO_3$

Rajiv made a model of a boat. When he places it in water. it sinks. According to Archimedes principle. why does the boat sink? A The boat is too small. B The buoyant force is less than the boat's weight. C The buoyant force is equal to the boat's weight. D The buoyant force is greater than the boat's weighL

Bellvue Company issues 10%, five-year bonds, on December 31, 2010, with a par value of $100,000 and semiannual interest payments. Use the following straight-line bond amortization table and make journal entries to record (a) the issuance of bonds on December 31, 2010; (b) the first interest payment on June 30, 2011; and ( c) the second interest payment on December 31, 2011.

Explain how an inclined plane makes loading a piano into a truck easier. Refer to the changing potential energy and kinetic energy of the piano as it (a) sits on the ground, (b) is being moved into the truck, and (c) sits in the truck.

Suppose that at any given time t (in seconds) the current i (in amperes) in an alternating current circuit is i = 2 cos t + 2 sin t. What is the peak current for this circuit (largest magnitude)?

Find a polynomial equation of least possible degree with integer coefficient whose roots include the given numbers. Use the result: If an equation with integer coefficients has a root $( a + \sqrt { b } )$ where a and b are rational but $\sqrt { b }$ is irrational, then the equation also has the root $( a - \sqrt { b } ).$ 1. -1. 0

Simplify.

a) $\left(2^2\right)\left(2^3\right)$

b) $\left(x^4\right)\left(x^3\right)$

What would be the consequence of setting the potential at $+100 \mathrm{~V}$ at infinity, rather than taking it to be zero there? a) Nothing; the field and the potential would have the same values at every finite point. b) The electric potential would become infinite at every finite point, and the electric field could not be defined. c) The electric potential everywhere would be $100 \mathrm{~V}$ higher, and the electric field would be the same. d) It would depend on the situation. For example, the potential due to a positive point charge would drop off more slowly with distance, so the magnitude of the electric field would be less.
