A fish swims 0.8 m/s for 34 m. How much time does it take the fish to swim this distance?
Do not round.
NO UNITS NEEDED.
Answer:
42.4m
Explanation:
Given parameters:
Speed of the fish = 0.8m/s
Distance = 34m
Unknown:
Time taken for the fish to swim = ?
Solution:
Speed is the distance divided by the time taken;
Speed = [tex]\frac{distance}{time}[/tex]
Time = [tex]\frac{distance}{speed}[/tex]
Now, insert the parameters and solve;
Time = [tex]\frac{34}{0.8}[/tex] = 42.4s
How does the concentration (amount) of carbon dioxide in the affect climate?
A. As carbon dioxide concentrations increase, temperatures decrease.
B. As carbon dioxide concentrations increase, temperatures increase.
C. Carbon dioxide concentrations have no affect on climate.
D. As carbon dioxide concentrations increase, temperatures become more random.
Answer:
A
Explanation:
When the carbon dioxide concentration goes down, temperature goes down. A small part of the correspondence is due to the relationship between temperature and the solubility of carbon dioxide in the surface ocean, but the majority of the correspondence is consistent with a feedback between carbon dioxide and climate.
Which statement correctly describes a characteristic that a scientific
measuring tool should have?
A. To be precise, it must be able to make measurements repeatedly
over a long period of time.
B. To be precise, it must be able to make measurements with small
units.
C. To be precise, it must be able to make measurements that are
close to the actual value.
D. To be precise, it must be able to make measurements with both
large and small units.
Answer:
A. To be precise, it must be able to make measurements repeatedly over a long period of time.
Explanation:
The precision of a scientific measuring tool can be defined as how close the values between multiple measurements are to each other, when repeated under the same conditions.
This ultimately implies that, the precision of a scientific measuring tool reflects the reproducibility and repeatability of its measurements, irrespective of how accurate the measurements are.
In science, one of the most effective ways to determine the precision of a scientific measuring tool is to find the difference between the highest and lowest measurements (measured values).
Hence, the statement which correctly describes a characteristic that a scientific measuring tool should have is that, to be precise, it must be able to make measurements repeatedly over a long period of time.

Does anyone know how to do this?
Answer:
yes
Explanation:
i don't have the periodic table in front of me right now but you will need it. for the first coloumn, look at the elemnt symbol and write it down. for example hydrogen H. the atomic mass will be written on the bottom of the entry. the atomic number is on the top. the number of protons is the atomic number. the neutrons is atomic mass-atomic number and the electrons you have to count the numbers in the upper right corner. depends what element you look at, there might be a couple rows of the electrons which are the shells. hope i helped :)
What is the energy of a wave with wavelength of 2.25nm?
Answer:
E = 8.84×10⁻¹⁷ J
Explanation:
Given data:
Wavelength of wave = 2.25 nm (2.25×10⁻⁹ m)
Energy of wave = ?
Solution:
Formula:
E = hc/λ
c = 3×10⁸m/s
h =6.63 ×10⁻³⁴ Js
now we will put the values,
E = 6.63 ×10⁻³⁴ Js × 3×10⁸m/s / 2.25×10⁻⁹ m
E = 19.89×10⁻²⁶ Jm / 2.25×10⁻⁹ m
E = 8.84×10⁻¹⁷ J

The image above shows a gas held in a chamber with a fixed volume. The gas begins with a temperature 333 K and a pressure of 4.00 atm (green) that increases to 7.65 atm (orange) as the gas is heated. What is the temperature of the gas when the pressure increases to 7.65 atm?
Answer:
636.86 K
Explanation:
From the question given above, the following data were obtained:
Initial temperature (T1) = 333 K
Initial pressure (P1) = 4 atm
Final pressure (P2) = 7.65 atm
Final temperature (T2) =?
NOTE: The volume is constant.
Since the volume is constant, we can obtain the new temperature the gas by using the following formula as illustrated below:
P1 /T1 = P2 /T2
4/333 = 7.65/T2
Cross multiply
4 × T2 = 333 × 7.65
4 × T2 = 2547.45
Divide both side by 4
T2 = 2547.45 / 4
T2 = 636.86 K
Therefore, the new temperature of the gas is 636.86 K
Answer:

what is the correct name for Ga(NO2)3?
Gallium Nitrite your welcome
A binary III/V direct bandgap semiconductor called gallium nitride is ideally suited for high-power transistors that can function at high temperatures. It has been widely utilized in light-emitting diodes (LED) since the 1990s. Its chemical formula is Ga(NO₂)₃.
Blu-ray discs are read using a blue light that gallium nitride emits. Gallium nitride is also utilized in lasers, photonics, RF components, and semiconductor power devices. GaN will be used in sensor technology in the future.
Gallium nitride power amplifiers are perfect for microwave and terahertz (ThZ) devices, such as imaging and sensing, the aforementioned future market, due to their capacity to operate at significantly higher temperatures and voltages than gallium arsenide (GaAs) transistors.

Answer:
On Sept. 15, 2020, NASA, in partnership with Future Engineers, launched the Artemis Moon Pod Essay Contest. The contest, which is open to all (public, private, and home school) students in grades K-12, asks participants to imagine they are leading a one-week expedition to the Moon’s South Pole. In the essay, students will need to describe to NASA what (and who) they would bring to help make their expedition a success.
The Moon Pod Essay Contest is presented in support of NASA’s Artemis program. The student challenge is part of NASA’s efforts to engage the public in its missions to the Moon and Mars. NASA is returning to the Moon for scientific discovery, economic benefits, and inspiration for a new generation. Working with its partners throughout the Artemis program, the agency will fine-tune precision landing technologies and develop new mobility capabilities that allow robots and crew to travel greater distances and explore new regions of the Moon.
