So i was wondering.... What are atleast 5 native birds to Washington state.... and what are atleast 5 migratory birds?

That's my main question...

if you have spare time, are there any laws set to protect these birds? THANX!!!!!

In a library, there were 5 shelves that each held an equal number of books. The librarian rearranged the books and moved them to 9 shelves. Each shelf still has an equal number of books. There are more than 140 total, but less than 200. How many books are on each of the 9 shelves now?

I watch star wars. How does lightsaver work? Is it possilbe to shot out energy like that and suddenly stop at about 1m? Is it possible to keep the energy beam like that in an open air? Also when the lightsaver hit other lightsaver how come it doesn't go thought? aren't they energy waepon not physical weapon with mass?

The exhaled carbon dioxide produced as a normal waste product of metabolism must be removed from the cabins of space vehicles. On the space shuttle, CO2 is removed from the cabin air by lithium hydroxide, which reacts as follows:

2 LiOH(s) + CO2(g) -----------> Li2CO3(s) + H2) (l)

What mass of CO2 can be removed from the atmosphere by 1.00 lb(454 g) of LiOH?

I heard there is many different way to get very close to light speed, even though theoretically mass traveling at speed of light is impossible. For example using matter anti-matter engine and cause continuous explosions would eventually accelerate up to velocity that is just under light speed. Ok here is what I don't know about. In this science fiction I read. As velocity increse the mass will increase, so when it get to near light speed the mass will increase up to even mass of saturn and go on. In this sf novel that I read. Space military used matter anti matter engine equipped missil to enemy planet to make gaint hole on thier planet or make the missil go fast as possible and increase mass so that it will become blackhole near enemy. Is it true that as velocity increase mass increase?

A soccer player kicks a soccer ball of mass 0.45 kg that is initially at rest. The player's foot is in contact with the ball for 3.0 x 10^-3 seconds, and the force of the kick is given by:
F(t) = [(6.0 x10^6)t - (2.0 x10^9)t^2] N
for 0 <_ t <_ 3.0 x10^-3 seconds, where t is in seconds. Find the magnitudes of:
(A) The impulse on the ball due to the kick.
(B) The average force on the ball from the player's foot during the period of contact.
(C) The maximum force on the ball from the player's foot during the period of contact.
(D) The ball's velocity immediately after it loses contact with the player's foot.

The answers are:
(A) 9.0 kg x m/s
(B) 3.0 kN
(C) 4.5 kN
(D) 20 m/s

But I don't know how to get these answers, please help Me!

A balll of mass m=60 g is shot with speed vi=22 m/s into the barrel of a spring gun of mass M= 240 g initially at rest on a frictionless surface. The ball sticks in the barrel at the point of maximum compression of the spring. Assume that the increase in the thermal energy due to friction between the ball and the barrel is negligible.

(A) What is the speed of the spring gun after the ball stops in the barrel?

(B) What fraction of the initial kinetic energy of the ball is stored in the spring?

The answers are:

(A) 2.35 x 10^3 J

(B) 352 J

If I see some science fiction movies like matrix, there are these snti gravity drivers. I heard theoretically it is impossible. But some people say it is possible to make anti gravity engine by rotaing it greater than 5000rpm and generate electromagnetic field.
