if a light wave has a wavelength of 5.80x10^-7 what is its frequency
Answers
Speed = v = 3×10⁸ m/s
Wavelength = λ = 5.8×10⁻⁷ m
Frequency = f
v = fλ
Hence,
f = v/λ
f = 3×10⁸ / 5.8×10⁻⁷
f = 0.517×10⁸⁺⁷
f = 5.17×10¹⁴ Hz
i hope this will help but if im wrong then it will be 5.16x10¹⁴

Answers
Answer: Velocity is a mathematical vector. That means it has both a magnitude (speed) and a direction. Scientists need to consider an object’s velocity to calculate its momentum — its velocity multiplied by its mass. Scientists use measures of velocity in everything from figuring out how much rain is falling to sending a rocket to space.
Explanation: Hope this help:)

Lysosome function
Mitochondria function
Vacuole function
Cell wall function
Chloroplast function
Ribosome function

Answers
Explanation:
GOLGI BODY - transportation of lipids and steroids.
LYSOSOME - destruction of malfunctioning or worn out cell organelles.
MITOCHONDRIA - oxides glucose to give energy to the cell in a form of cellular respiration.
VACUOLE - FOOD VACUOLE for storage of food while WATER VACUOLE eliminates excess water by a process called OSMOREGULATION.
CELL WALL - provides rigidity for the plant cell.
CHLOROPLAST - pigmented organelle of the plant which functions to manufacture food by a phenomenon known as PHOTOSYNTHESIS.
RIBOSOME - synthesizes protein and enzymes.
ENDOPLASMIC RETICULUM - The ROUGH ENDOPLASMIC RETICULUM has RIBOSOMES attached to it while the SMOOTH ENDOPLASMIC RETICULUM has nothing attached, they transport proteins and enzymes
Why are engineers called applied scientist?
Answers
Answer:
Applied science is a discipline that is used to apply existing scientific knowledge to develop more practical applications, for example: technology or inventions. In natural science, basic science (or pure science) is used to develop information to explain phenomena in the natural world.
Answer:
• Because engineers apply science and its theories into practical situation
Take an example of;
→ A generator: When creating a generator, electromagnetic induction theorem is applied. [ self and mutual inductance ]
→ A plane: The wings are made in considerance of Bernoulli principle and viscous drag

Copper occurs naturally as a mix of two isotopes: Copper-63 with a mass of 62.930 amu and copper-65 with a mass of 64.928 amu. The percent abundance of copper-63 is 69.09%.
Calculate the atomic mass of copper.
Answers
Answer: 63.55
Explanation:
The attached chart shows the calculation. The orange line points to the % abundance of Cu-65, which is the difference of 100% less the % Abundance of Cu-65 (since there are only 2 isotopes).
The weighted average contribution of each istope is calculated (blue arrow) and then summed to find the atomic mass of copper.

I would say D) A new substance is formed with different properties.
It doesn't nesisarally have to have a specific change (except mass), but it could be a wide variety of changes.
Answer:
A New substances form with different properties
Explanation:
When two different chemical substances are combined, they form new substances with different properties. The properties may be modified and the substance formed may exhibit better characteristic than individual properties of its components. For example, when sodium and chlorine combine, they form sodium chloride. Sodium chloride has different properties than any of the constituents.

If i blow up a ballon, tie it off, and release it, it will fall to the floor, why does it fall instead of float
Answers
Answer:
The balloon would fall because carbon dioxide, the gas you exhale and blew up with, is denser than air and therefore will fall. Helium however, is less dense than air and floats.

once an enzymatic reaction is completed, the enzyme releases what?
Answers
Answer:
Once an enzymatic reaction is completed, the enzyme releases substrates.
Explanation:
The enzyme will always return to its original state at the completion of the reaction. One of the important properties of enzymes is that they remain ultimately unchanged by the reactions they catalyze. After an enzyme is done catalyzing a reaction, it releases its products (substrates).
