PLEASE HELP ME IT IS DUE TODA You have arrived at the scene of a two-car accident. You know the following pieces of information:
Car 1 and Car 2 have equal masses of 2,000 kg each.
Car 1's initial momentum was 40,000 kg-m/s to the right; Car 2 wasn't moving.
Car 1 collided with Car 2.
Car 1's final velocity is 10 m/s to the right; Car 2's final velocity is unknown.
1. What is each car's initial velocity? (4 points)
2. What is their total initial momentum? (4 points)
3. After the collision, what is Car 2's final velocity? (4 points)
4. What is their total final momentum? (3 points)

Please don't answer with some weird link because I wont click on it so please don't use up a potentially helpful answer with some useless scam, thanks!!

the answers are as following:

1. c. double helix, nucleosome, coil, supercoil, chromosome

2. b. g2 phase, preparation for mitosis

3. d. interphase consists of the g1, s, and g2 phases

4. c. metaphase

5. a. chromosomes are duplicated before cell division so that each new daughter cell has a complete set

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
