Answer:
daughters cells
Explanation:
when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a type of cell division in which one cell (the mother) divides to produce two new cells (the daughters) that are genetically identical to itself.

What is electromagnetic waves?The oscillations between an electric field and a magnetic field produce waves known as electromagnetic waves, or EM waves. In other words, magnetic and electric fields oscillate to form electromagnetic (EM) waves.
When an electric field interacts with a magnetic field, electromagnetic waves are created. Therefore, they are referred to as "electromagnetic" waves. An electromagnetic wave's electric field and magnetic field are perpendicular to one another (at right angles). Additionally, they are perpendicular to the EM wave's direction. An electromagnetic wave can pass through any medium, including vacuum, solid materials, and air. It can spread or move from one area to another without the use of a medium.

A wheel initially rotating at 12 rad/s decelerates uniformly to rest in 0.4 s. If the wheel has a rotational inertia of 0.5 kg.m², what is the magnitude of the torque causing this deceleration? (A) 1.5 N.m (B) 15 N.m (C) 30 Nm (D) 38 Nm
Answer:
(B) 15 N.m
Explanation:
The deceleration of the wheel is first found by using the following formula:
[tex]\alpha = \frac{\omega_f - \omega_i}{t}[/tex]
where,
α = angular acceleration = ?
ωf = final angular speed = 0 rad/s
ωi = initial angular speed = 12 rad/s
t = time = 0.4 s
Therefore,
[tex]\alpha = \frac{0\ rad/s - 12\ rad/s}{0.4\ s}\\\\\alpha = -30\ rad/s^2[/tex]
here, the negative sign shows deceleration.
Now, we find the torque responsible for this deceleration:
[tex]\tau = I\alpha[/tex]
where,
τ = torque = ?
I = rotational inertia = 0.5 kg.m²
Therefore,
[tex]\tau = (0.5\ kg.m^2)(30\ rad/s^2)\\[/tex]
τ = 15 N.m
Therefore, the correct answer is:
(B) 15 N.m
Technician A says that high-intensity discharge (HID) headlights are brighter and have a blue tint. Technician B says that one defective turn signal bulb can cause the turn signal on the affected side to stop blinking (flashing). Who is right?
a) technician A
b) technician B
c) both technicians A and B
d) neither technician A nor B
Answer:
The right option is;
d) Both technicians A and B
Explanation:
High-intensity discharge (HID) headlights is an electrical gas-discharge light that gives a very bright light when an arc is formed between the tungsten electrodes that have a transparent or translucent housing
The light is ideal for night driving due to its brightness and appear to have a bluish tint at night although the light produced by HID headlight is actually more similar to Sunlight around noon
A turn signal bulb is a flashing light indicator that shows that a vehicle is about to turn or change lanes
An issue with the wiring, a broken connection at the bulb socket or a burnt bulb can result in a condition of "no turn signal" in which the turn signal stops flashing or blinking. Therefore both technicians A and B are correct.

Roark saw Alejandro sitting by himself in the quad and leaning over, with his head resting on the heels of his hands. Roark approached him and said, "Hey Alejandro, you look sad." Alejandro responded, "Huh? No, I'm just thinking." Which difficulty in interpreting nonverbal behavior does this exchange exemplify?
A. Nonverbal messages are often ambiguous.
B. Nonverbal messages are continuous.
C. Nonverbal cues are multichanneled.
D. Nonverbal interpretation is culture-based.
Answer:
Option A
Explanation:
Nonverbal communications are ambiguous because some times the face expressions (non verbal signals – Sad face or sitting alone gesture of Alejandro) and the verbal signals (communication between Roark and Alejandro) do not match or contradict each other. Some people prefer to believe on their interpretations of the nonverbal signals as compared to that of the verbal signals
Hence, option A is correct.

How do I remove the paint from the carpet. Please I need a real answer.
Answer:
Explanation:
(water based paint)
If the paint stain is still wet, simply blot the spot with a wet paper towel - don’t scrub, just blot.
If the paint stain is dry, use hot water and a little bit of dish detergent. Let the solution sit for a few minutes to soften the paint.
Once the paint is softened, use a knife or pin to scrape the paint stain. Continue to add more solution as you scrape.
If the paint is still not softening, consider using a handheld steamer while you scrape to eventually remove the paint stain from the carpet.
(latex based paint)
Blot the spot to remove as much wet paint as possible – don’t scrub, or you’ll push the paint further down into the carpeting.
Mix a cup of lukewarm water with one teaspoon of dishwashing detergent – just make sure the detergent is mild.
Work from the outside of the paint stain to the inside, gently blotting the affected area.
After letting the area dry completely, follow up by vacuuming.
(oil based paint)
If the paint stain is dry, you’ll want to use a steamer to soften the stain.
Apply steam directly to the stain.
Simultaneously pick at the paint stain with a needle or a pin to try and break it up.
Continue until stain is removed, without damaging fibers.
What is due to acids formed when atmospheric and volcanic gases mix with water
Answer:
Acid rain results when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents. The SO2 and NOX react with water, oxygen, and other chemicals to form sulfuric and nitric acids. These then mix with water and other materials before falling to the ground.

Please help me with a speech.The topic of my speech is Passion.
Answer:
Explanation:
Passion
For me, standing on the summit of Mt Everest was the result of following a process. The process of mountaineering. I love mountaineering. I am passionate about it. I love the months of planning for an expedition, the months of sweating and training to prepare my body physically. The meticulous preparation of my equipment. Most of all I love the huge mental challenge I have to overcome before each climb to confront my own fear. All these reasons are why I climb, they are why I climbed Mt Everest and that is why I continue to climb.
Passion is an enormously powerful force. It gives us the strength to get through hard times and setbacks. It gives us strength to overcome our fears, to ignore what other people think of us, to be disciplined and make sacrifices in pursuit of our dreams. Passionate people do not want to take shortcuts – they consider that ‘learning the process’ is an important part of the journey.
In mountaineering it’s easy to spot those who are not passionate about the process. They want to stand on top of the mountain but they are not really interested in the process of climbing the mountain. I feel for these people. Success without hard work is a hollow, empty feeling. They never last long in the sport.
Just as in life, successful mountaineers are the ones who are passionate. They are not there just to stand on the summit. Their passion gives them the energy to work the hardest, fight the longest, and in the words of Winston Churchill “never, never. never give-up”.

The displacement current density between the plates of a parallel-plate capacitor is uniform and has a magnitude of 19.9 A/m2 as the capacitor is being charged. What is dE/dt, the rate at which the electric field strength is changing between the plates
Answer:
[tex]\dfrac{dE}{dt} \approx 2.261 \overline {36} \times 10^{12} \ V/ms[/tex]
Explanation:
The parameters given in the question are;
The magnitude of the displacement current density between the plates of a parallel-plate capacitor, J = 19.9 A/m²
We have;
[tex]i_d = \epsilon _0 \times \dfrac{d \Phi_E}{dt} =\epsilon _0 \times A \times \dfrac{d E}{dt}[/tex]
Therefore;
[tex]\therefore \dfrac{dE}{dt} =\dfrac{i_d}{\epsilon _0 \cdot A} =\dfrac{J}{\epsilon_0} = \dfrac{19.9}{8.8 \times 10^{-12}} \approx 2.261 \overline {36} \times 10^{12}[/tex]
Therefore;
[tex]\therefore \dfrac{dE}{dt} \approx 2.261 \overline {36} \times 10^{12} \ V/ms[/tex]

Answer:
polar covalent bonding
Explanation:
Water (H2O) is polar because of the bent shape of the molecule. The shape means most of the negative charge from the oxygen on side of the molecule and the positive charge of the hydrogen atoms is on the other side of the molecule. This is an example of polar covalent chemical bonding.
Un avión despega a las 2:00 p.M en un vuelo de 2500 millas. El avión llega a su destino a las 7:30 p.M. Explicar por qué hay el menos dos momentos durante el vuelo en los que la velocidad del avión es de 400 millas por hora.
Answer:
Por lo tanto, cuando la velocidad promedio del avión es mayor que la velocidad de vuelo posible dada, entonces es posible tener dos puntos durante el vuelo cuando la velocidad es la de la velocidad dada
Explanation:
La hora de despegue del avión, t₁ = 2:00 p.m.
La distancia del vuelo que viaja el avión = 2,500 millas
La hora de llegada del avión al destino, t₂ = 7:30 p.m.
El tiempo de vuelo, Δt = t₂ - t₁
Por lo tanto, Δt = 7:30 - 2:00 = 5 horas 30 minutos = 5,5 horas
La velocidad media del avión,[tex]v_{ave}[/tex] = (Distancia total) / (Tiempo total)
= 2,500 millas / (5,5 horas) = 454. millas por hora
La velocidad promedio se puede encontrar también sumando velocidades individuales y dividiendo el resultado por el número de velocidades sumadas en la suma
Por ejemplo, tenemos;
∴ [tex]v_{ave}[/tex] = (v₁ + v₂ + v₃ )/3
Si durante el vuelo horizontal directo, la velocidad máxima, v₃ = 509 millas por hora, y v₁ y v₂ son puntos donde el avión se mueve en ángulo con la horizontal y, por lo tanto, velocidad horizontal reducida, entonces tenemos;
En el camino hacia arriba sobre una nube con velocidad horizontal v₁
454.[tex]\overline{54}[/tex] = (v₁ + 509)/2
2 × 454.[tex]\overline{54}[/tex] - 509 = 400.[tex]\overline{09}[/tex] = v₁
∴ v₁ = 400.[tex]\overline{09}[/tex] mph ≈ 400 mph
De manera similar, en el camino de regreso a la elevación del vuelo, tenemos v₂ = 400.[tex]\overline{09}[/tex] mph ≈ 400 mph
Por lo tanto, cuando la velocidad promedio del avión es mayor que la velocidad de vuelo posible dada, entonces es posible tener dos puntos durante el vuelo cuando la velocidad es la de la velocidad dada.
An Athelice complete :Round of a circular track of diameter 200m in base Distance travelled by athletes And displacement
Answer:
Distance = 1256 m
Displacement = 0
Explanation:
Distance :
Distance may be defined as the actual length between two points along its path.
It is a scalar quantity and its value can be positive or zero.
Displacement :
Displacement is defined as the shortest length between two point , i.e. between the initial point and the final point.
It is a vector quantity and it has values which can be either positive or negative or zero.
From the question, the diameter of the circular track is, r = 200 m
∴ Distance travelled by an athlete is = circumference of the circular track
= 2πr
= 2 x 3.14 x 200
= 1256 m
Displacement = 0 (since the original point coincides with the final point).
