I dont get how multiplying logs means you add them, i just do not grasp the idea.

for example (lets take logs to base 10)

log 10 * log 10 = 1

log 10 + log 10 = Log 100 = 2

The answer is not the same, so I just dont understand how

log3 x ylog5 be comes log3 + ylog 5

I know that

log a - log b = log (a/b)
log A + log b = log ab
log a^b = bloga.

Am i missing something glaringly obvious?

Its used for moving small amounts of liquid, its used by squeezing the end of it. I think its a 'perpet' or something but i don't know how its spelt. First correct wins a best answer.

A scientist reports the detection of an atomic particle that came toward his experiment from outer space at 4(10^5) km s^-1. What conclusion can we draw from this report?
a)he has made an error in his experiment, since such a speed i concidered to be impossible by all previous experiments.
b)this "particle" must have been a photon or quantum of electromagnetic radiation of very high energy in order to have traveled this fast.
c)this result is acceptable since atomic particles can travel this fast, whereas larger bodies are limited to 3(10^5) m s^-1.
d) This is an acceptable result for a particle originating from outer space, since particle speed from such regions is unlimited.

The only way I can think of doing it is graphically, if you have a triangle with sides a, b, c, (c is the longest) and no angles, and you have to find the area, the only way I came up with was drawing a graph and finding out the crossing point of the circles of radius a and b, with centres on the origin and (c,0) respectively, where the x- and y-values are both positive. I then used that y-value as the height and c as the base. But surely there's a better way than that?

Hi,

I have a physics midterm today and this is one of the review problems:

A block of mass m starts from rest at height h. It slides down a frictionless incline, across a rough horizontal surface of length L, then up a frictionless incline. The coefficient of kinetic friction on the rough surface is Uk.

a) What is the block's speed at the bottom of the first incline?
b) How high does the block go on the second incline?

Give your answers in terms of m, h, L, Uk, and g.


Help would be greatly appreciated!


Thank you!
