Answer:Static electricity can be created by rubbing one object against another object.
Explanation: This is because the rubbing releases negative charges, called electrons, which can build up on one object to produce a static charge
Choose ALL that apply for NEAP tides Moon and Sun are at right angles to the Earth gravity of the Sun and Moon work against each other Moon, Sun, and Earth are in alignment smaller than normal range of highs and low tides
Answer:
i think it is..... smaller than normal range of highs and low tides
Moon and Sun are at right angles to the Earth
Explanation:
Moon and Sun are at right angles to the Earth and gravity of the Sun and Moon work against is the right statement about NEAP tides.
What are tides?Tides are the cyclic deformation of water body occur due to external gravitational force.
NEAP tides are also known as small tides as their heights are not very much and this is occur due to opposite attraction of water towards the gravity of the sun and moon. As sun and moon are present in the right angle direction with respect to the earth.
Hence, option (1) & (2) is correct, i.e. gravity of sun and moon is opposite and they are present at the right angle to the earth.

Which radioisotope requires long-term storage as the method of disposal, to protect living things from radiation exposure over time?
Pu-239
FR-229
Fe-53
P-32
Answer:pu-239
Explanation:
Pu-239 is regarded as the radioisotope requires long-term storage as the method of disposal, to protect living things from radiation exposure over time
Disposal of radioactive nuclear waste is often regarded as a problem.
The waste sources are:
Nuclear power reactors Bomb-related nuclear materialDisposal of bomb-grade plutonium is often difficult.
The longer lived isotopes are:
Plutonium-239 whose t1/2 is 24,110 years, Plutonium-240 whose t1/2 is 6,540 years, Curium-245 whose t1/2 is 8,500 years. etc.The storage of the longer lived elements is through containment for the next several thousand of years.
The control or management of radioactive waste is a hard, multifaceted procedure.

What is the mass of 3.25 moles of sodium hydroxide (NaOH)?
Answer:
1 mole is equal to 1 moles NaOH, or 39.99711 grams.
Explanation:
Hope this helps have a nice day :)
The statement of the mass of sodium hydroxide (NaOH) is "130 g."
What is mass?A substance is something to do with mass that takes up space. The mass of a compound is the total amount of atoms present in grams that make up a molecule. The grams is the unit of mass.
In order to determine the mass in grams, multiply moles of the substance value by its molar mass to convert moles into grams.
Mole to gram conversion factor,
[tex]=\;given \;mole\;.\;\frac{grams}{1\;mol}[/tex]
Mass of NaOH comes out to be,
[tex]=\;3.25\;mol\;.\;\frac{39.997\;g}{1\;mol}[/tex]
= 129.99 g
= 130 g
Hence the correct answer is 130 g.

Mutation can cause antibiotic resistance, C. Bacteria that become resistant are an example of evolution D. Antibiotics killing bacteria while allowing mutated bacteria to live is an example natural selection. 5. Identitfy ONE difference between kingdoms Archaea and Bacteria.
Answer:
A. Antibiotic resistance can sometimes be shared among bacteria.
B. Mutation can cause antibiotic resistance.
D. Antibiotics killing bacteria while allowing mutated bacteria to live is an example natural selection.
Explanation:
Identifying: Archaea have cell walls that lack peptidoglycan and have membranes that enclose lipids with hydrocarbons rather than fatty acids (not a bilayer). ... Bacteria: cell membrane contains ester bonds; cell wall made of peptidoglycan; have only one RNA polymerase; react to antibiotics in a different way than archea do.
Hope this helps, I reported some answer that was absurd, not applicable, incomplete and confusing
Mutation can cause antibiotic resistance, Bacteria that become resistant are an example of evolution. Antibiotics killing bacteria while allowing mutated bacteria to live is an example natural selection The correct options are B, D, and C.
What are archaebacteria and bacteria?Archaea, like bacteria, lack interior membranes but have a cell wall and swim with flagella.
Archaea differ from bacteria in that their cell wall lacks peptidoglycan and their cell membrane contains ether linked lipids rather than ester linked lipids.
The dispersion of antibiotic resistance in pathogenic bacteria is a simple and elegant example of natural selection at work.
Bacteria can develop antibiotic resistance through mutations that alter antibiotic cellular targets or by acquiring dedicated resistance genes from other bacteria.
Antibiotic resistance can be caused by mutation; bacteria that become resistant are an example of evolution. Natural selection is demonstrated by antibiotics killing bacteria while allowing mutated bacteria to live.
Thus, B, D, and C are correct options.
