Hey thanks. One more problem really quickly. Finals are tommorow.
The density of diamond, a form of carbon, is 3520 kg/m^3. How many carbon atoms are there in a solid diamond sphere with a radius of .03mm?
Work so far :
V=R^3pie=(.033)^3pie
PV=nRT
Density*Volume=Mass= 3520*(.033)^3 pie
Thanks I get. A, B, D, E
C. So I just sketch 8 crests and 8 troughs right?
I still do not get
F, G and H and I
I don[t konw how to sketch the equations.
ok here's what I have so far
a. SqRoot(T/(m/l)= Frequency so I get Sqroot(500/(.01/.4)) * (.4) = 56.6 m/s. But that's obviosly incorrect because I got it wrong.
b. nv/2l= 7(56.6)/2(.4)= 49.5 cycles/s
c. No idea where to begin
d. 1/7 * 495/7 = 7(56.6)/2(.4)=.8m
e. 70.7 cycles/s
f. no idea...
Hey I'm a junior this year and physics finals are coming up. I managed to get B- on all 3 quarters up until now. And If i cannot get atleast a 92% on my final, I will end up with a C for the year . So any kind souls out here who can help please it will be appreciated with such a gratitude like...
A 7 kg box increases its speed form 2 to 4 m/s over a horizontal distance of 5 meters. coefficient fo kinetic friction is .1. what was the average force applied tothe box int he direction of the motion?
sorry, I am just too used to using X and Y, Ok B and C it is.
Assuming Up and Right is Positive and Left and Down is negative.
Vector A, being 25 N of E, would be in the 1st quadrant and so both its components are positive.
Vector B woudl be in the 4th quadrant. So its Y values would be...
Hey I have this question about vectors that I can't solve. Can someone explain it to me?
Vector A is 1550 25 degrees North of East. Vector B is 41 East of South. Vector C was 35 North of West. A+B+C=0. Find B and C.
