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!

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: Acceleration = 5m/s^2; Distance traveled = 320 m

Explanation:

Velocity of car = 40m/s

Time taken = 8 seconds

Acceleration = ?

Distance traveled = ?

A) Since acceleration is the rate of change of velocity per unit time

i.e acceleration = velocity / time

acceleration = 40m/s / 8 seconds

Acceleration = 5m/s^2

B) To get how far the car traveled before stopping, obtain the distance from the formula:

velocity = distance traveled / time

40m/s = distance / 8 seconds

Distance = 40m/s x 8 seconds

Distance = 320 m

Thus, the car’s acceleration is 5m/s^2 while it traveled 320 metres before stopping.

Final answer:

Acceleration and distance traveled during car's stoppage are -5 m/s² and -160 meters respectively.

Explanation:

Acceleration: To find the car's acceleration, we use the formula: acceleration = (final velocity - initial velocity) / time taken. Substituting the values, we get acceleration = (0 - 40 m/s) / 8 s = -5 m/s².

Distance Traveled: To calculate the distance the car travels while stopping, we use the equation: distance = initial velocity * time + 0.5 * acceleration * time^2. Substituting the values, the car travels a distance of -160 meters while stopping.

Answer:

As per law of conservation of momentum

1 × 10 = 50× v

v = 1/5 m/S

Or

20 cm/s

Final answer:

The velocity of the man after throwing his shoes is -0.2 m/s.

Explanation:

To determine the speed of the man after throwing his shoes, we can use the principle of conservation of momentum. The initial momentum of the man and his shoes is zero, as they are both at rest. When he throws his shoes, their momentum becomes non-zero, but the total momentum of the system remains zero.

Since the shoes have a mass of 1 kg and a velocity of 10 m/s, their momentum is calculated by multiplying the mass and velocity, giving us a momentum of 10 kg·m/s. To maintain the total momentum at zero, the man's momentum must be -10 kg·m/s.

Since momentum is the product of mass and velocity, we can rearrange the equation to solve for the velocity of the man. Dividing the momentum by the mass of the man (50 kg), we find that the velocity of the man is -0.2 m/s.

Answer: able to conduct electricity

Explanation: refer to pic

Answer: 0.01 m/s2

Explanation:

Given that:

Velocity of supertanker = 7.2 m/s (about 12 mph)

Time taken = 12 min

(Since the SI unit of time is seconds, convert 12 minutes to seconds

1 minute = 60 seconds

12 minutes = 12 x 60 = 720 seconds)

Average deceleration = ?

Recall that deceleration is obtained by dividing velocity by time taken.

i.e Deceleration = velocity / time

Deceleration = 7.2 m/s / 720 seconds

= 0.01 m/s2

Thus, the magnitude of its average deceleration is 0.01 meters per second squared.

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]

Resistance, R = 240 Ohms

Answer:

340 Hz

Explanation:

The frequency of a wave is the number of oscillations completed by the wave per second.

For a wave, the relationship between wavelength of the wave and its frequency is given by the wave equation:

[tex]v=f\lambda[/tex]

where

v is the speed of the wave

f is its frequency

[tex]\lambda[/tex] is its wavelength

In this problem, we have a sound wave, with wavelength of

[tex]\lambda=1m[/tex]

The speed of sound waves at room temperature is

[tex]v=340 m/s[/tex]

Therefore, using the previous equation, we can find the frequency of the wave:

[tex]f=\frac{v}{\lambda}=\frac{340}{1}=340 Hz[/tex]

The frequency of the sound wave with a wavelength of 1 meter in room temperature air would be approximately 343 hertz (Hz).

To find the frequency of a sound wave when given its wavelength, we can use the formula for the speed of sound in a medium, which is given by:

[tex]\[ v = f \times \lambda \][/tex]

where [tex]\( v \)[/tex] is the speed of sound in the medium, [tex]\( f \)[/tex] is the frequency of the sound wave, and[tex]\( \lambda \)[/tex] is the wavelength of the sound wave.

We know that the speed of sound in room temperature air (which is approximately 20°C or 68°F) is about 343 meters per second (m/s). The wavelength [tex]\( \lambda \)[/tex] given in the question is 1 meter.

Rearranging the formula to solve for frequency[tex]\( f \)[/tex], we get:

[tex]\[ f = \frac{v}{\lambda} \][/tex]

Substituting the known values into the equation:

[tex]\[ f = \frac{343 \text{ m/s}}{1 \text{ m}} \] \[ f = 343 \text{ Hz} \][/tex]

Therefore, the frequency of the sound wave with a wavelength of 1 meter in room temperature air is 343 Hz. This frequency corresponds to a pitch that is slightly higher than the B4 note on a musical scale, which is close to the upper limit of what most people can comfortably hear.
