Why do commercial airliners encounter very little turbulence above 25,000 feet?
Group of answer choices
There are no clouds above 25,000 feet.
Water vapor has mostly disappeared at colder elevations and its effect on weather turbulence.
The air is so thin at altitudes above 25,000 feet that turbulence has much less effect.
The jet stream produces a much smoother flow of air.
Answer:
Water vapor has mostly disappeared at colder elevations and its effect on weather turbulence.
Explanation:
Answer:
B. Water vapor and its effect on weather turbulence has mostly disappeared at colder elevations.

Cobalt (Co) has an atomic mass of 59 and an atomic number of 27. Which statement correctly describes an atom of cobalt?
A. An atom of cobalt contains more neutrons than protons.
B. An atom of cobalt contains more electrons than protons.
C. An atom of cobalt contains the same number of neutrons and protons.
D. An atom of cobalt contains the same number of neutrons, electrons and protons.
Answer:
A
Explanation:
27 us the number of protons when we subtract 27 from 59 it will be 32 because a mass number is the sum of proton and neutron but tell u more on the comment
Answer: A - An atom of cobalt contains more neutrons than protons.
Explanation: The atomic number is the number of protons in an atom. The atomic mass is the sum of protons & neutrons in an atom. So, with simple math we can figure out the number of neutrons. Total 59 - 27 protons = 32 neutrons. Which means that A is the only right answer in this case.
Little Extra: A & B would both be correct if Cobalt was a negatively charged ion. An atom is an ion if it is charged, and an ion is either negatively charged or positively charged. For example, if Cobalt had 27 protons & 26 electrons it's overall charge would be positive since it has more protons than electrons. And it would be negatively charged if Cobalt had 27 protons & 28 electrons. No charge if there are 27 protons & 27 electrons because proton +1 and electron -1. Imagine 27-27=0 no charge, 27-26= +1 charge, 27-28= -1 charge

Blaire is teaching her little brother to ride his bike. She uses 7 N of force to push a 14 kg bike. What is the acceleration?
98 m/s2
0.5 m/s2
21 m/s2
2 m/s2
Answer:
The solution is
Explanation:
a = f/m
a =7/14
a=1/2
a=0.5
Acceleration of bike is 0.5 m/s²
Given that:Force used in push = 7 N
Mass of bike = 14 kg
Find:Acceleration of bike
Computation:Force = Mass × Acceleration
Force used in push = Mass of bike × Acceleration of bike
7 = 14 × Acceleration of bike
Acceleration of bike = 7 / 14
Acceleration of bike = 0.5 m/s²

Theresa creates an experiment where she mixes two red-colored substances together in a container and observes the solution slowly changing from red to blue for the next eight minutes. The solution becomes completely blue after eight minutes. What does this represent about the type of change happening in the container?
Complete Question:
Theresa creates an experiment where she mixes two red-colored substances together in a container and observes the solution slowly changing from red to blue for the next eight minutes. The solution becomes completely blue after eight minutes. What does this represent about the type of change happening in the container?
Group of answer choices
A. A chemical change started immediately and finished at eight minutes.
B. A non-chemical change started immediately and finished at eight minutes.
C. A chemical change occurred at four minutes.
D. A non-chemical change occurred at four minutes.
Answer:
A. A chemical change started immediately and finished at eight minutes.
Explanation:
A chemical reaction can be defined as the chemical process which typically involves the reaction between two or more chemical elements (substances) to form a new compound, through the rearrangement of the ionic or molecular structure of each chemical element.
This ultimately implies that, a chemical reaction is a chemical change that immediately starts when two or more molecules of a chemical element (substance) known as reactants are combined together to form a new product (compound).
In this scenario, Theresa creates an experiment where she mixes two red-colored substances together in a container and observes the solution slowly changing from red to blue for the next eight minutes. The solution becomes completely blue after eight minutes. Thus, what this represent about the type of change happening in the container is that, a chemical change (from red to blue) started immediately and finished at eight minutes.

Nuclear fusion reactions release more energy than fission reactions while also generating less waste. However, nuclear fusion reactors are not currently used to generate electricity.
What is the main reason for this?
Nuclear fusion reactions release high energy and required tremendous temperature of nuclear reactors is the main reason for not used to generate electricity.
What are nuclear reactions?Nuclear reactions are those reactions which are taking place in the nucleus of any unstable atom and produces energy.
As in the question it is given that nuclear fusion reactions releases more energy and less wastage, but this energy are releases in the tremendous amount which can be proved harmful for the environment and the humans. To carry out this reaction we have to maintain the very high temperature of nuclear reactors of about 6 times greater than sun's temperature, which is not possible manually.
Hence, high temperature of nuclear reactors and high amount of energy released is the main reason.
