they begin to move quickly and can break away from other molecules
Answer:
When solid changes atoms/molecules begin to speed up and move around. Compared to when they are in the solid phase, where they barely move and are slow and are compacted.
Which point on the standing wave will not move?
Answer:
B
Explanation:
A P E X
According to Mendel's law of segregation, what takes place during meiosis?A.Pairs of alleles cross over on chromosomes, exchanging one for anotherb.Pairs of alleles separate in meiosis, and each gamete receives one allele of a pairc.Part of an allele is separated, or broken off, from its chromosomed.One chromosome is suppressed, and the other chromosome of the pair determines the traits of the offspring
Answer:
b. Pairs of alleles separate in meiosis, and each gamete receives one allele of a pair.
Explanation:
Gregor Mendel, who is referred to as the FATHER OF GENETICS because of his contribution to the principles of inheritance, proposed in one of his laws called LAW OF SEGREGATION that the alleles of a gene will separate into gametes in such a way that only one of the two alleles that make up a gene will be in each gamete.
This division/separation of alleles during gamete formation is called MEIOSIS. Note that, allele is one member of a gene. Hence, according to Mendel, in meiosis, pairs of alleles separate and each gamete receives one allele of a pair.
Norma drives her car for 150 min at 40 km/h, then rests for 75 min, and then drives for 3.15 h at 60 km/h. What was Norma’s average speed?
Answer:
Norma’s average speed is 41.9 km/h.
Explanation:
The average speed is given by:
[tex] \overline{v} = \frac{d_{T}}{t_{T}} [/tex]
Where:
[tex]d_{T}[/tex]: is the total distance
[tex]t_{T}[/tex]: is the total time
We can find the total distance as follows:
[tex] d_{T} = v_{1}*t_{1} + v_{2}*t_{2} = 40 \frac{km}{h}*150 min*\frac{1 h}{60 min} + 60 \frac{km}{h}*3.15 h = 289 km [/tex]
Now, the total time is:
[tex] t_{T} = t_{1} + t_{2} + t_{3} = 150 min*\frac{1 h}{60 min} + 75 min\frac{1 h}{60 min} + 3.15 h = 6.9 h [/tex]
Hence, the average speed is:
[tex] \overline{v} = \frac{d_{T}}{t_{T}} = \frac{289 km}{6.9 h} = 41.9 km/h [/tex]
Therefore, Norma’s average speed is 41.9 km/h.
I hope it helps you!
Please help !! I have no clue how to do this
Answer:
THIS IS SUPER EASY!!!!!!
BOLD = ANSWER
Explanation:
REMEMBER: force = mass x acceleration
4. 6.0kg x 4.0m/s2 = 24N
5. 7.5kg x 8.3m/s2 = 62.25N
6. 2,000kg x 8.3m/s2 = 16,000N
REMEMBER: mass = force / acceleration
7. 6.0N / 3.0m/s2 = 2kg
8. 6.0N / 12.0m/s2 = 0.5kg
9. 20.0N / 5.0m/s2 = 4kg
10. 20.0N / 2.0m/s2 = 10kg
11. 4.0N / 7.3m/s2 = 0.55kg
12. 4.6N / 16.3 m/s2 = 0.28kg
I hope this helps u! :D
