Consider square 4. You can get there with a 4 from square 0, or with a 2 from square 2. But it's not fair to take P(4) + P(2) = 3/36 + 1/36 = 1/9, since it's not certain that you'll ever land on square 2! You need to take the chance of landing on square 2 times the chance of rolling a 2 and...
I want to know the probability of landing on each individual square if you go around the board once. Therefore, the probability of landing on squares one and two are correct because you would not go back around the board after you pass the last square.
The tricky part is that after square 2 you...
If you are given two dice and a gameboard how would you figure out the probability of landing on each of the individual squares in one game?
Since there are two dice with 6 faces you can make a few statements without much math:
0 possibility of landing on first square,
(1/6)*(1/6)...
Apparently I am making the whole problem more difficult than it actually is. I want to make sure that I understand everything about this kind of situation. I think that because the string is rigid it is throwing me off. Could you let me know if I have the concept right?
Normally buoyancy force...
So the question asks "What is the weight W_b of the ball?" and 2.94-(890*0.00006*9.81)=2.42 is incorrect, then they are simply asking for the weight=mg?
I misread the question, sorry. I understand that the scale will not change its reading, so W_2= 1N, but how would you find the weight of the ball? I thought it would be:
m(ball)*g - rho_f*V*g
In answering the original question:
A cylindrical beaker of height 0.100 {m} and negligible weight is filled to the brim with a fluid of density rho = 890 {kg/m}^3. When the beaker is placed on a scale, its weight is measured to be 1.00 {N}.
A ball of density rho_b = 5000 {kg/m}^3 and volume V...
Homework Statement
A ball of mass m_b and volume V is lowered on a string into a fluid of density rho_f. Assume that the object would sink to the bottom if it were not supported by the string.
What is the tension T in the string when the ball is fully submerged but not touching the bottom...

Thank you for the explanation of emf as induced emf. Your explanation makes it much more clear.
So if you are given a graph of B on the z axis with time on the x-axis when you knew the Bfield was perpendicular to the plane of the loop (which is on the paper) you could say that the emf was going...
Homework Statement
a) If B (magnetic field) is perpendicular to the plane of a circular loop, then is it true that when B increases the induced emf is clockwise and when the B decreases the emf is counterclockwise? Or do you need to know whether it is pointing into/out of the page? Or would...
