To test the performance of its tires, a car
travels along a perfectly flat (no banking) cir-
cular track of radius 564 m. the car increases
its speed at uniform rate of
a 101
al = 410 = 3.62 m/s2
dt
until the tires start to skid.
if the tires start to skid when the car reaches
a speed of 35 m/s, what is the coefficient of
static frictionsbetween the tires and the road?

How can one distinguish breccia from conglomerate? a. breccia contains angular clasts and conglomerate contains rounded clasts. b. breccia contains rounded clasts and conglomerate contains angular clasts. c. different minerals cement breccia than cement conglomerate. d. breccia contains sand and conglomerate contains silt.

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.

The graph describes the motion of an object. the object moves with from a to b. it from b to c. it moves with from c to d.
