Kristin decides to do an experiment to determine which type of sock absorbs
the most sweat. Which of these describes her doing step fourof the inquiry
process?
A. Kristin measures the weight of five different kinds of socks before
and after she goes running.
O
B. Kristin wonders which of the five types of socks in her drawer
seems to be the most absorbent.
O
C. Kristin predicts that all-cotton socks will absorb the most sweat,
because she thinks cotton is very absorbent.
D. Kristin finds that socks made of a polyester-cotton blend weigh
0.05 ounce more after she runs in them.

If a spring has a k value of 100 newtons per meter and it is stretched 0.50 meters, what is the restoring force of the spring?

The first-order reaction a→2b+c has rate constant 0.538 s−1. if the initial concentration of a is 0.867 mol l−1, what is the half-life of the reaction in seconds? remember to use correct significant figures in your answer (round your answer to the nearest hundredth). do not include units in your response.

Abasketball star covers 2.65 m horizontally in a jump to dunk the ball. his motion through space can be modeled precisely as that of a particle at his center of mass. his center of mass is at elevation 1.02 m when he leaves the floor. it reaches a maximum height of 1.90 m above the floor and is at elevation 0.910 m when he touches down again. (a) determine his time of flight (his "hang time"). (b) determine his horizontal velocity at the instant of takeoff. (c) determine his vertical velocity at the instant of takeoff. (d) determine his takeoff angle. (e) for comparison, determine the hang time of a whitetail deer making a jump with center-of-mass elevations yi = 1.20 m, ymax = 2.45 m, and yf = 0.750 m.
