Someone wrote me this:
Make yourself a diagram of this, and assume that the "man" keeps his arm straight while throwing the ball. (If he bends his elbow, all bets are off.) You'll see that you have a couple of similar figures: one with the portion of the arm between the socket and the point...
No. Unfortunately no. I cannot believe my professor is even asking me to solve this question. But I will post some up a little later to assist you with the Human anatomy part of this problem.
Homework Statement
1. Consider a man throwing a baseball. Given the following, calculate the velocity of the ball as it leaves his hand:
1. The distance from his shoulder socket (humeral head) to the ball is 70 cm.
2. The distance from his humeral head to the points of insertion of the...
For C, the professor's question was "How much greater is the total surface area of these 100 droplets compared to the original single droplet?"
Should I subtract instead of dividing? It seems like his question can be interpreted in multiple ways!
Total Surface Area of 100 Small Droplets =...
Also in case you are wondering- I got the 6.0 from my answer to question "A"
What is the surface area to volume ratio of the droplet?
Answer: 6.0
Surface Area / Volume = 4 x (3.14) x .5^2 / (4/3) x 3.14 x .5^3 = 6.04 or 6.0
Gerben... I worked out the equation based on your thoughts and some research. I hope this looks right or kinda right. Can you take a look B, C, and D to see if its interpreted correctly? Thank you so much. You are a life saver!
.00523333333333 = (4/3) x 3.14 x r^3
Multiply both sides by...
Thanks for the clarification. I will find the volume right now and will post the latter part of my answer in a few hours, after my class. Volume = 4/3πr3
Volume = (4/3) x 3.14 x 0.005^3 = 5.23333333334e-7Or in the alternative:
It could be
Volume = 4/3πr3 Volume = (4/3) x 3.14 x 0.5^3 =...
Question A was What is the surface area to volume ratio of the droplet?
Answer: 6.0
Surface Area / Volume = 4 x (3.14) x .5^2 / (4/3) x 3.14 x .5^3 = 6.04 or 6.0
I don't understand. I thought that radius is already understood given that we were given the diameter of 1 cm. I was under the impression that radius is .5 cm / 100 droplets which equals 0.005 cm. In other words, can I plug in "0.005" whenever "r" in the original surface area / volume equation...
Homework Statement
Suppose a lipid droplet is essentially a sphere with a diameter of 1 cm.
For A – D below, the area of a sphere is 4π r2, and volume is 4/3πr3.
For π, use a value of 3.14.
