I've been stuck on this problem for a while. I need this equation for another question. here it is:
The unit conversion coefficient (u) for the equation R= u*C*I*A is 0.278. How do you calculate this number?
Units are :
R= m/s, C=unitless, I=mm/hr and A=km^2
I need help.

ALERT: THIS IS A MATH PROBLEM

Here's how it works, each day I dump out all the skittles and whatever side faces no 'S' then I eat it. Next day I do the same till there's none left.

And no I can't actually buy a big bag of Skittles and try it. So how would I explain this in a paragraph?

What exactly are plant hormones?? i have a science project to study the growth of a plant..and the effect of plant hormones...
but i have no clue what it is and my teacher is offering no guidance so...
are plant hormones only specific to roots or does it help with the growth of other parts of the plant?
and also is it applied to the plant directly? or is it something you add when its a seed?
last thing--does it speed up the process...increase the chances of it producing riper fruits...? i really have no clue what hormones are so if you could give some basic background info plus answer these questions, it would be much appreciated!!:):)thnxxx

Two friends want to close their heavy door, but are too lazy to get up. They agree to throw an object at the door to close it. Ernie suggests throwing a 300 g lump of sticky clay at the door, but Bert argues that a 300 g tennis ball would work better if thrown at the same speed. Who is correct? Explain in detail, basing your explanation on fundamental physics principles.

As she was going through the wood, she met with a fox, who conned her out of 1/5 of cakes she was carring to her grandmother.

After that she met with a wolf, who demanded 1/4 of remaing cakes.

After that she met with a bear, who demanded 1/3 of remaing cakes.

1/2 of remaining cakes the girl ate herself, and delivered 1 cake to her grandmother.

How many cakes did her mother gave her in the beginning?

1)If the hanging mass is 100. g and drops a distance 25.5 cm in a time of 6.0 s, what is the moment of inertia of the support rod and shaft? The radius of the shaft is 0.50 cm.

2)Now two masses each of 180 g are placed on the rod at a distance of 15.0 cm from the point of rotation. What is the TOTAL moment of inertia of the masses plus rod and shaft?

3)How long does it take for the hanging mass to fall the same distance 25.5 cm?

please show work so I can understand the problem
