The base height of the dingdong plant is 10 cm. Four genes contribute to the height of the plant, and each dominant allele contributes 3 cm to height. If you cross a 10-cm plant (quadruply homozygous recessive) with a 34-cm plant, how many phenotypic classes will there be in the F2?

4
5
8
9
64

I am a 16 yaer old kid, so don't suggest stuff that cost over $150.
I already know the basic programming language, so i would prefer a basic stamp controller. But i also need a dev board which is the most expensive, i checked ebday, but the only good ones are expenisve (100 and up), and cost is a MAJOR problem. I am going to make my first robot, but i am planning to go into contests for robots to win more $$$, so i would prefer that i could switch th ic to a better faster stamp later on when i have more money. My first one is gonna be a line follower, then im gonna modify it to "visualize" and make paths to another place (i know this involves complex coding). So any ideas?

A 100 gram cue ball traveling at 500 cm/s hits a rack of 15 billiard balls of equal mass. The cue ball is stopped in the collision. Assume all 15 billiard balls move away at the same speed.

A. What is the total momentum before and after the collision?
B. What is the speed of each ball after the collision?

Any help appreciated, I have no clue how to approach this!
