Answer: C

Production of electricity from nuclear energy does not produce greenhouse gases that contribute to global warming

Explanation: Nuclear energy is considered as non-renewable energy source. Although nuclear energy itself is a renewable energy source, the material used in nuclear power plants is not.

Nuclear power emits more greenhouse gases per kilowatt hour than all renewables, including biomass, hydroelectric, solar and wind. Reactors produce significantly less carbon dioxide than all fossil fuels. We can therefore conclude that Production of electricity from nuclear energy does not produce greenhouse gases that contribute to global warming.

The answer is C. Production of electricity from nuclear energy does not produce greenhouse gases that contribute to global warming. Sorry that this is super late, but I still wish you good luck with the rest of your work!

Explanation:  We have seasons because Earth's axis – the imaginary line that goes through the Earth and around which the Earth spins — is tilted. It's tilted about 23.5 degrees relative to our plane of orbit (the ecliptic) around the Sun. As we orbit our Sun, our axis always points to the same fixed location in space. Our northern axis points almost directly toward Polaris, the North Star.

Answer: The pH decreases

Explanation:

- Hydrochloric acid, as an acid has a pH value below 7

- Sodium hydroxide, as an alkali has a pH value above 7.

The alkali neutralizes the acid to give a salt as in the equation:

HCl(aq) + NaOH(aq) --> NaCl(aq) + H2O(l)

Hence, the aqeous sodium chloride, NaCl has a pH value of 7 (neutral) which is then a decrease from the above 7 pH value of the sodium hydroxide solution.

Thus, the pH decreases

Answer:

compound

Explanation:

A compound is composed of two or more different elements combined together. Water is made up of 2 atoms of hydrogen and one atom of oxygen combined together. Water is therefore made up of two separate elements, which makes it a compound.

Water (H₂O) is a compound made of hydrogen and oxygen in a fixed ratio, while a single atom of oxygen (O) is an element.

Elements consist of only one type of atom, while compounds are made of multiple types of atoms.

Answer:Electrons are transferred in the formation is ionic bonds.

Explanation:Why is because ionic bonds are caused by electrons transferring from one atom to another.

Electrons are transferred in the formation of ionic bonds, leading to the creation of oppositely charged ions that attract each other due to electrostatic forces. This process differs from covalent bonding, which involves the sharing of electrons instead of a full transfer.

Electrons are transferred in the formation of ionic bonds. When an electron is transferred from one atom to another, it results in the creation of two oppositely charged ions: a cation, which is positively charged, and an anion, which is negatively charged. These ions are then attracted to each other due to their opposite charges, and this electrostatic attraction is what constitutes the ionic bond.

Unlike covalent bonds, where electrons are shared between atoms, ionic bonding involves a full transfer of electrons. Ionic compounds, such as sodium chloride (NaCl), are typical examples where the sodium atom donates an electron to the chlorine atom, leading to the formation of Na+ and Cl- ions.

Furthermore, ionic bonds are essential in creating compounds with stable electron configurations, often resulting in the formation of a crystalline lattice structure. The strength of the ionic bond is influenced by the charge and size of the ions. Highly charged and smaller ions will tend to form stronger ionic bonds due to the greater electrostatic forces at play.

Answer:3 and 4

Explanation:

Answer:

D on Edge

Explanation:

Answer:

80 amperes

Explanation:

Current in the circuit = ?

Voltage in the circuit = 160 Volts

Resistance = 2 Ω

Voltage = Current x Resistance

V = IR

160V = I x 2 Ω

I = 160V / 2 Ω

I = 80 Amperes

Therefore the current in the circuit is 80 amperes :)

The current through the 160V circuit with a resistance is 2Ω is 80 Ampere.

From Ohm's law, the relationship between voltage (V), current (I), and resistance (R) can be expressed as:

V = I × R

Given the parameter:

Voltage V = 160 V

Resistance R = 2 ohms

Current I = ?

Plug the given value into the equation and solve for the current I:

V = I × R

160 = I × 2

I = 160/2

I = 80 Ampere

Therefore, the current I is 80 Ampere.

Answer:

The answer is D.

Explanation:

There is no gravity in Space so that means that it will decrease your weight but not your mass.

Your mass would remain the same on the Moon or any other celestial body because it is a constant measure of the matter within you. However, your weight would be less on the Moon due to its weaker gravitational pull compared to Earth. The correct answer, therefore, is B - your weight would be less but your mass would remain the same.

When considering the comparison of weight and mass on the Moon versus the Earth, it's important to clarify the difference between the two concepts. Mass is a measure of the amount of matter in an object, and it remains constant regardless of location. On the other hand, weight is the force exerted on an object due to gravity and varies depending on the gravitational pull of the celestial body you're on.

The acceleration due to gravity on the Moon is approximately 1.625 m/s², significantly less than the Earth's gravitational acceleration of 9.80 m/s². So, if you were to move from Earth to the Moon, your mass would remain the same because the quantity of matter you consist of does not change. However, because the Moon's gravity is weaker, you would weigh less. This decrease in weight is attributed to the lower gravitational pull, not to a loss of mass.

The correct answer to the question posed is: B. your weight would be less but your mass would remain the same. This reflects the understanding that while the gravitational force acting on you decreases, the actual matter that you are made of does not change.

In the Brønsted-Lowry theory, an acid is a species that can donate a proton, expanding the definition of acids and bases beyond the Arrhenius theory to include a wider variety of chemical reactions.

According to the Brønsted-Lowry theory of acids and bases, an acid is defined as a species that can donate a proton (hydrogen ion, symbolized as H+) to another molecule. This concept was introduced in 1923 when Johannes Brønsted and Thomas Lowry independently proposed that acids and bases should be defined by their ability to donate and accept protons, respectively. This definition broadened the understanding of acids and bases beyond the previous Arrhenius definition, which was limited to substances dissociating in water to provide hydronium and hydroxide ions.

For example, in the reaction between ammonia (NH3) and water (H2O), ammonia acts as a Brønsted-Lowry base by accepting a proton from water, which acts as a Brønsted-Lowry acid. As a result, the ammonium ion (NH4+) and hydroxide ion (OH−) are formed:

NH3(aq) + H2O(l) ⇒ NH4+(aq) + OH−(aq)

Answer:

B) Periodic Motion

Explanation:

When a pendulum is friction-less, i.e there are no damping forces acting on it, its motion will be periodic, i.e it will bob up and down going from potential energy to kinetic energy and back. Thus, the motion of the pendulum can be best described by the term "period motion", hence choice B.

If however, forces do act on the pendulum, and if they acts as to damp the pendulum, it will oscillate less and less as time goes by, and eventually come to a stop (in the real world this damping force is usually air resistance ). And if the force acts in such a way that it increases the oscillations, the pendulum will swing higher and higher, and the system will go haywire! :)

The resistance of the lamp plugged in to a standard wall outlet with a current of 0.5 amps is 240 Ω (ohms)

Explanation:

In the United States Of America the standard voltage is 120 v and their frequency is 60 Hz

Standard wall outlet voltage is 120 V

The current in the lamp is 0.5 ampere

Resistance (R) = V/ I

      = 120/0.5

      = 240Ω (ohms)

Thus the resistance of the lamp plugged in to a standard wall outlet with a current of 0.5 amps is 240 Ω (ohms).

The resistance of the lamp when it is plugged into a standard wall outlet is 240 Ohms.

Given the following data:

Note: In the United States of America, a standard wall outlet supplies a voltage of 120 Volts.

To determine the resistance of the lamp when it is plugged into a standard wall outlet, we would apply Ohm's law:

Ohm's law states that at constant temperature, the current flowing through an electrical circuit is directly proportional to the voltage (potential difference) applied across its terminals and inversely proportional to the resistance in the electrical circuit.

Mathematically, Ohm's law is given by the formula;

[tex]V=IR[/tex]

Where;

Making R the subject of formula, we have:

[tex]R=\frac{V}{I}[/tex]

Substituting the given parameters into the formula, we have;

[tex]R=\frac{120}{0.5}[/tex]

Explanation:

he dry adiabatic rate is the rate at which dry air changes its temperature as a result of expansion or compression. The dry adiabatic rate is 1.0o C/100 meters. Air rises and cools at the dry adiabatic rate up to the level of condensation where dew point temperature is reached.

The dry adiabatic rate is the rate of temperature change in unsaturated air as it ascends or descends in the atmosphere, approximately 1 degree Celsius per 100 meters. This rate applies until the air becomes saturated, after which it cools at the wet adiabatic rate.

The dry adiabatic rate, often used in meteorology, refers to the rate at which a parcel of dry or unsaturated air changes temperature as it moves vertically in the atmosphere. This rate is approximately 1 degree Celsius per 100 meters (or 10 degrees Celsius per kilometer) of ascent or descent. However, this rate holds true only for dry or unsaturated air; once air becomes saturated, it cools at a different rate known as the wet adiabatic rate.

To illustrate, imagine a balloon filled with air that's heated and starts to rise. As the balloon ascends, the pressure around it decreases. This causes the air in the balloon to expand and cool. This cooling process continues at the dry adiabatic rate until the air in the balloon becomes saturated.
