First of all, this is the chemistry section, while your question is a physics question. Anyway I'll tell you how to solve it.
First we need to find the rate that the truck moves in a second.
1km = 1000m
40km = 40000m
40000m/hr
1 hour = 60 minutes
40000m/hr ÷ 60 = 666.66(repeating)/minute
1 minute = 60 seconds
666.66m/min ÷ 60 = 11.11(rep)m/s
Next we simply multiply the speed of the truck by the number of seconds it travels.
11.11 × 5 = 55.55
Make sure to round it unless you indicate the repeating decimal.
The truck moved 55.56m in 5 seconds.
Answer:
4,2,1,3
Explanation:
4. A small ribosomal subunit binds to a molecule of mRNA5. the anticodon of an incoming aminoacyl tRNA base-pairs with the complementary mRNA codon in the A site.
2. The large ribosomal subunit attaches with the initiator tRNA with the amino acid methionine (Met) located in the P site.
1. The ribosome translocates the tRNA in the A site to the P site and the empty tRNA in the P site is moved to the E site where it is released.
3. A release factor, a protein shaped like an aminoacyl tRNA, promotes hydrolysis and releases the polypeptide.
The answer is b. Food chains are extremely fragile. In many occasions, the health of a species will depend on the survival of the species right under. At the end, we realize that the chain is quite fragile because everyone depends on each other, but not every species are strong enough to survive the change in their environment.
Answer:
The pH at the equivalence point is 7.0.
Explanation:
This is because the solution only contains water and a salt that is neutral.
Since neither H+ or OH-, molecules remain in the solution.
We can conclude that the equivalence point is 7.0.
The people use Earth's motion to determine units of time because of its uniform motion which is consistent.
<u>Explanation:</u>
In earlier days, people used to observe the motion of Earth to measure time. This is because, the Earth is moving at constant speed and at constant acceleration. So the change in position of the sun or stars can be easily correlated to the time.
Due to the consistency in the Earth's motion and the accurate repetition of the time period along with the seasons, the Earth's motion can be considered as a responsible source to determine the units of time.
