1. i) For what values of a with the expression log2a: a) yield positive numbers? b) yield negative numbers? c) yield numbers greater than 1? d) yield numbers between 0 and 1? e) be zero? f) be undefined? Solution: 1. a) a > 1 b) 0 < a < 1 c) ? d) ? e) a = 1...

Question: 1. A clock is hanging on wall. length of minute hand is 16cm and the length is 8cm for the hour hand. The highest that the tip of the minute hand reaches above ground is 265cm. a) What is equation of axis, amplitude & period in minutes of function that represents the tip of hour...

I do not understand positive and negative intervals and increasing/decreasing intervals. I included 2 examples from my textbook which I did not understand and I was wondering if someone can explain it to me. Example 1: f(x) = 2 - x x intercept is (2, 0) and y-intercept is (0,2)...

what if the d-t graph had a curved line? does the same thing apply?

I was wondering if someone can explain to me in detail on how to accurately draw a velocity-time graph and an a-t graph when the d-t graph is given.

Question: Solve the following vector equations mathematically: a) a + b b) c- d c) 2a -1/2b d) a + c +b Given: a = 10m[R] b = 20m[L] c = 10m[U] d = 5m[D] Solution: a) 10m [R] - 20m [L] = 10m [L] b) 10m [U] - 5m [D] = 5m [U] c) 20m [R] - 10m [L] = 10m [R] d) a + c +b = 10m[R] + 10m...

Homework Question: Four identical 4Ω resistors have been connected in such a way that their total resistance is 4Ω. Draw a diagram to show how they are connected. My Question: How do you solve a question like this? How do you classify it as a parallel or series circuit or does it even...

Well in my demonstration, I'm planning on taking an empty can and filling it with 1/3 of water to make it rotate in a circular motion on its edge. After I'm going to fill it with smashed ice instead of water and do the same thing.

I have a project to do and I have to make a demonstration about a physics phenomenon. I'n planning on doing a demonstration that explains one or all of Newton's Laws of Motion. I've chosen to do it on the center of gravity, but I want to know if it's related to Newton's 3 Laws of Motion or is it...

I actually have to find the following: RT = ? IT = ? I1 =? I3 =? I6 =? I4 = ? V2 = ? V5 = ? V7 = ? I tried solving by adding R7 and R9 (from step 2) together using the series formula. I only had to find 2 more values (V7 and I7)but then I had difficulty figuring out how to find the value of V7...

I've attached a conbined circuit diagram to this post. I have to solve the circuit. I know that I have to simplify the diagram into a series circuit to make it easier to solve, but I'm having trouble with a few parts in the diagram. This is how I simplified so far: 1. I added R6 and R5...

SERIES CIRCUIT QUESTION Given: R1 = 24 Ω R2 = 8 Ω R3 = 60 Ω Homework Question: a) Which resistor would have the greatest current passing through it? Explain. b) Which resistor would have the greatest potential difference across it? Explain. PARALLEL CIRCUIT QUESTION given...

So, if I'm solving for µk, how do I find Ff (the force of friction)? What formula do I have to use?

Am I looking fo µs or µk?

Fred (60 kg) is rollerblading at a velocity of 25 km/h [E] when he sees a broken glass bottle on the path ahead. He brakes and is slowed to a velocity of 8 km/h [E] in 4.2 s. What is the coefficient of friction between Fred's rollerblades and the ground? (Hint: Find FN and Ff first.) Given...
