In bats, black, (B) is dominant to chesnut(b) and solid color (S) is dominant to spotted (s) .

What are the genotypes of the parents that would produce a cross with 3/8 black solid, 3/8 black spotted, 1/8 chestnut solid, and 1/8 chestnut spotted bats?

How would I figure this out?
I have no idea how to do this...

Ok, I have a physics question. Now, I know this is easy but it's just not coming to me. You don't have to give me the calculations or anything like that but can you just help me and tell me what to do in order to find it please?

F is for force (I'm sure everyone knows that)
Given F1 = 36 Newtons (25 degrees North of East) and F2 = 42 Newtons ( 15 degrees east of south), determine the force F3 that must be added to the sum of F1 + F2 to produce a net force of zero.

Please I know it's easy but can you tell me how to find it.

Also, I have another question:
The force of gravuty on a textbook is 18 newtons (down):
a) What's the net force on the book if it is held stationary in your hand?
b) Neglecting air resistance, what's the net force acting on the book if you suddenly remove your hand?

Now, I'm aware that for part a) , the net force is 0 because thaere's no force acting on it besides gravity and they cancel out anyways but what about for part b) , can someone help me?

There's a song about "flying into the star's corona" and the concept of doing something like that amazes me. Even if it's totally out there, could we ever invent technology to fly into a star? Or would the gravity just crush us to death no matter what?

I know other ppl have similar questions but they are close now. I would really appreciate it if u could all give me your opinion. Its kinda like a survey. Also i probably shouldnt do this but if your question is sorta like mine fill free to email for information or if u have information that could help me. my email is miz_tweety_4_lyfe@yahoo.com.

On star trek, when photon torpedoes are fired they appear as red (or another color) blobs of light, if photon torpedoes are perported to travel faster than the speed of light how can the human eye perceive them as light blobs?

Photon Torpedoes

Photon torpedoes are the principal faster then light weapon system used my most major cultures in the alpha quadrant. Torpedoes have been preferred in FLT combat due to phasers EM energy is diminished when it hits the light barrier, although recent developments have allowed phasers to be used at warp velocities.

Photon torpedoes were first developed by the Federation in 2215, to replace earlier nuclear weapons. These torpedoes were extremely limited and used only for defense of a starship, due to their relatively low yield and short range. These torpedoes worked on a simple 1:1 matter, anti-matter reaction, where deuterium slugs were injected into a magnetically contained antideuterium. The early torpedoes had a tactical range of 750,000
