Im having a problem with curve sketching i can't figure out how to do this problem. I am confused. Heres the question 1. For the following curve find: a)the domain b)the intercepts c)the asymptotes d)intervals of increase or decrease: local maximum and minimum e)concavity and the...

Sir, 1)When one of the prongs of a tuning fork is cut, why does its frequency increase? Is it because the damping forces exerted by the prongs on each other decreases? 2)When an incident wave and its reflected wave superimpose, it is said that both standing waves and progressive...

A water trough is 6 m long and has a cross-section in the shape of an isosceles trapezoid (dimension shown in the diagram.) Water is being pumped into the trough at a rate of 0.5 m^3/min. How fast is the water level rising when it is 0.5 m deep. AFAIK the volume of a trapazoid like this should...

Sir, The diameter of a metal ring is D and the coefficient of linear expansion is y. The temperature of the ring is increased by 1 degree Celsius. What is the increase in area of the ring? I solved it the following way: Coefficient of superficial expansion = 2y Initial area of the...

A dipole lies on the X axis , with the positive charge q at x=d/2 and negative charge -q at x=-d/2 .i know that the electric flux through the surface in YZ plane (midway between the charges) will be zero .now this surface is rotated so that the normal to the surface is no longer parallel to the...

In an experiment I heated a room and logged the temp change as it went up. One of the walls in the room is made of plywood. I also logged the temp on this surface (on the heated side). When I looked at the graph after the experiment I noticed that as the air temp of the room went up, the surface...

Supposing I started off with a particle, which I know exactly the state it is in, hence, it is in a pure state. And hence also, its entropy is zero. Now, suppose we throw the particle into the black hole and be sucked in, then, then the area of the black hole increases and hence, the entropy of...

hey guys, just wondering if i did this correctly a spherical balloon is to be filled with water so that there is a constant increase in the rate of its surface area of 3cm2/sec . a) Find the rate of increase in the radius when the radius is 3cm. b) Find the volume when the volume is...

I have conducted an experiment in school I have some problem with it . I connect a resistor 6600 ohm to a 6V direct current and I read the miliammeter and it show about 0.9 mA . But after I connect a capacitor 3300 F parallel to the resistor , the miliammeter increase to more than 1 mA.Why the...

Driving along a crowded freeway, you notice that it takes a time t to go from one mile marker to the next. When you increase your speed by 4.0 mi/h, the time to go one mile decreases by 9 s. What was your original speed in mi/h? (this is from chapter 1 in my physics book, but it's been a long...

Assuming free will is the ability to choose and does exist. I had a dream that I was a machine, that everything I did was a response to a stimuli...kinda like that movie Awakenings where the patient aren't capable of initiating an action on their own but can only respond to external stimuli...

OK, I'll admit...I am only a beginner, if even. I understand why time and length are effected by speed. But I've never understood why mass increases. Would someone kindly show me how and why mass increases the faster an object goes (using mathematical language understandable by someone who...

hi, i was just wondering as the mass of the black hole keeps increasing due to increased mass getting deposited on it does its event horizon increase because of this? does the black hole have infinite density? -Benzun

Hello All I have this problem that I have no idea how to do. F = flux or the volume of blood to flow past a point R = radius F=kR^4 Show that the relative change in F is about four times the relative change in R. How will a 5% increase in radius affect the flow of Blood?? How...

Can someone explain to me the following: If a number increases from 108,7 to 113,7 how much in percent has it increased? First I tried to do 108,7 / 113,7 = 0,956. 1 - 0,956 = 0,0439. In other words, an increase of 4,39%. This turns out to be wrong. 113,7 / 108,7 = 1,0459 -> an increase of...

When two electrons move away from each other, does the potential energy of the system increase or decrease?

www.mybiopro.com/savefuel ... can anyone tell me if you can actually increase fuel efficiency by resonating gas, and can someone maybe send me some links (if you know any) that explain how these things actually resonate the fuel without any external power source. AND if they don't have a power...

Is it possible to have an INCREASING speed AND have the MAGNITUDE of acceleration decreasing? If so please give examples. I asked my TA this question today and she did not know the answer...? Help!

I *think* I remember hearing something about a study that showed just thinking about working out was able to increase muscle mass.. was this true?

I am looking for the ultimate reference to the notion by Einstein, that increase in Acceleration will result in increase in Mass? Any links or handwaving would be much appreiciated, as I intend to place a fundamental number of questions, in order to expand my knowledge on LQG, thanks.

I don't know why I can't figure this one out tonight. I just can't think straight and I am hoping someone can help ASAP. Here is the question: In 1998 revenue from gambling was $651 million. In 2001 the revenue increased to $2.4 billion. What is the geometric mean annual increase for the period?

I know it increases mass, since KE = 1/2 mv^2 and as you approach the speed of light KE keeps going up meaning mass must go up. I've been told that this is simply an increase in relativistic mass (the e=mc^2 type) and gravity is based on rest mass. But isn't it kind of weird for everything...
