Open Question: what are some actions that individuals, or society as a whole,take in order to help us, but actually hurt us?
Open Question: How close would the masses 0.470 kg and 0.102 kg have to be in order for the gravitational force between them?
The basic formula is F = G Mm/ R^2
G is the universal constant of gravitation. ( = 6.67 * 10 ^ -11)
Rewriting we get R = sqrt ( G Mm/F)
= sqrt(6.67 * 10 ^ -11 * 0.47 *0.10/1.01)
=1.76 * 10 ^ -6 m.
Open Question: What is the Minimum velocity with which we have to travel in order to feel the effect of Time Dilation?
Pandu Member since:July 31, 2009Total points:94 (Level 1)Another thing. I know Gravity affects time. So what are the combined effect of speed and gravity on timeAnswer Question
by LeAnne Member since:June 15, 2006Total points:107,320 (Level 7)The dilation of time would not be felt even at 99.999% the speed of light - you would experience time just as you do on the surface of the earth. However, if you were to send a message back to earth, your 30 minute message (by your clock) would drag on for hours on earth.Gravity and acceleration have the exact same effects concerning physical laws.
Open Question: After fertilization what is the correct order of events?
B. Implantation of embryo in uterine wall -> Stimulates corpus luteum to grow -> Embryo secrets HCG
C. Implantation of embryo in uterine wall -> Embryo secrets HCG ->Stimulates corpus luteum to grow
D. Continued secretion of progesterone and estrogen -> Embryo secrets HCG -> Stimulates corpus luteum to grow -> Implantation of embryo in uterine wall
Open Question: How do you find the order of a field?
Spunky08 Member since:February 21, 2009Total points:154 (Level 1)Let say we have the field Z3[x] and we have f(x) = x^3 + x^2 + x + 2 such that f(x) is an element in Z3[x]. We know that since f(x) is irreducible in Z3 then we have the field Z3[x] /
Open Question: arrange the bonds in order of increasing polarity? I-F, Br-F, Br-Br?
I is less electronegative than Br so it does not pull the electron density as much as bromine would.
Because F is the most electronegative, more electron density is towards the F when the other atom is less electronegative
And Br-Br is last because the electron density is shared equally
Open Question: ) A quadrant of radius , centred at is cut from the above desk in order to create a computer work-station d?
Find the mass of the computer work-station desk.
Write down the double integrals that give the co-ordinates of its centre of mass. Note that you are not required to find the centre of mass.
Square desk has co ordinates on (0,0) (2a,0) (0,2a) (2a,2a)
Open Question: Applications of first order linear ODEs. Calculus?
An office contains 1000 ft^3 of air initially free of carbon monoxide. Starting at time = 0, cigarette smoke containing 4% carbon monoxide is blown into the room at the rate of 0.5 ft^3/min. A ceiling fan keeps the air in the room well circulated and the air leaves the room at the same rate of 0.5ft^3/min. Find the time when the concentration of carbon monoxide reaches 0.01%.
I'm always having trouble setting up this equation
I know s = smoke;
so DS/dt = in - out
[4% * 0.5ft^3/min] - [0.01% * 0.5ft^3/min ] I know I'm missing some variables such as t, to find the time when concentration of smoke is 0.01%
My assumption is 4% of 1000ft^3 so that there is 9060ft^3 = air while 40ft^3 = smoke in.
0.01% of 1000 is 9090 = air and 10 = smoke.
Just need help setting up the question and understanding how to get it.
