Jeremy has a handful of resistors. all of them, except one, have four bands. the exception has three. why? a. he should use another because the band may haven't been printed or worn out, and using the resistor could damage the circuit since there's no way to tell its value due to the missing band. b. the resistor has a tolerance of 20%. c. the resistor has a non-decimal value, like 10 ohms, instead of 10.4 ohms. d. the resistor has a low resistance value so it properly only has three bands.

A2000 kg car is rounding a curve of radius 200 m on a level road. the maximum frictional force the road can exert on the tires of the car is 4000 n. what is the highest speed at which the car can round the curve?

The ph is the a.independent variable b.the dependent variable c.control group

Aparticle's position is given by x = 3.00 - 9.00t + 3t2, in which x is in meters and t is in seconds. (a) what is its velocity at t = 1 s? (b) is it moving in the positive or negative direction of x just then? (c) what is its speed just then? (d) is the speed increasing or decreasing just then? (try answering the next two questions without further calculation.) (e) is there ever an instant when the velocity is zero? if so, give the time t; if not, answer "0". (f) is there a time after t = 3 s when the particle is moving in the negative direction of x? if so, give the time t; if not, answer "0".
