Answer:

G. it enables people to use pots and pans made of metal to cook food

Explanation:

Metals are known to be substances with a relative high melting point, which means that it takes a very high temperature to melt them. As used in this question, copper (Cu) and iron (Fe) at metallic elements that have high melting points.

One advantage of this property based on the options provided is that "it enables people to use pots and pans made of metal to cook food". This is because cooking food requires subjecting them to a constant temperature from a heat source e.g cooker or stove.

The material used to hold the food being cooked must possess a very high melting point to withstand the heat, hence, the importance of these metallic substances. Most pots and pans are made of steel, an alloy of iron, hence, they have high melting point.

Answer:

0.5*0.8*45^2. =810J

Explanation:

KE=1/2 mv^2

Answer:

The total mechanical energy of the pizza crust is 19.2 J.

Explanation:

Mechanical energy is that which a body or a system obtains as a result of the speed of its movement or its specific position, and which is capable of producing mechanical work. Then:

Potential energy + kinetic energy = total mechanical energy

Kinetic energy is a form of energy. It is defined as the energy associated with bodies that are in motion and this energy depends on the mass and speed of the body.

Kinetic energy is defined as the amount of work necessary to accelerate a body of a certain mass and in a position of rest, until it reaches a certain speed.

Kinetic energy is represented by the following formula:

Ec = ½ *m*v²

Where Ec is kinetic energy, which is measured in Joules (J), m is mass measured in kilograms (kg), and v is velocity measured in meters over seconds (m / s).

In this case:

Replacing:

Ec = ½ *0.547 kg*(5 m/s)²

and solving you get:

Ec= 6.8375 J

On the other hand, potential energy is the energy that measures the ability of a system to perform work based on its position. In other words, this is the energy that a body has at a certain height above the ground.

Gravitational potential energy is the energy associated with the gravitational force. This will depend on the relative height of an object to some reference point, the mass, and the force of gravity. Then for an object with mass m, at height h, the expression applied to the gravitational energy of the object is:

Ep = m*g*h

Where Ep is the potential energy in joules (J), m is the mass in kilograms (kg) is h the height in meters (m) and g is the acceleration of fall in m / s² (approximately 9.81 m/s²)

In this case:

Replacing

Ep= 0.547 kg *9.81 m/s²* 2.30 m

and solving you get:

Ep= 12.342 J

So:

Total mechanical energy= 12.342 J + 6.8375 J

Total mechanical energy= 19.1795 J≅ 19.2 J

The total mechanical energy of the pizza crust is 19.2 J.

hope you have a good day!

Answer:

W = mg

Explanation:

The formula of Weight for given mass is

[tex]\large\boxed{\fcolorbox{blue}{yellow}{W = mg}}[/tex]

where,

m = mass of the body

g = accelaration due to gravity

For Example:

Q.) A body has mass 10 kg then fine it's weight

A.)

m = 10kg

g = 10m/s²

.°. W = mg

= 10 × 10

W = 100N

Thus, The weight of a body from its mass can be calculated by W = mg.

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.

Answer:

Net force = the difference between the forces of two directions

Net force= 60N-(30N+20N)

=60-50

Therefore Net force = 10N

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).

Answer:

Explanation:you knoe i know

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.

Answer:

E = 0.4 kWh

Explanation:

Given that,

The power of a bulb, P = 40 W

Time, t = 10 hours

We need to find the energy used by the bulb. Let it is equal to E. So,

[tex]E=P\times t\\\\E=40\times 10\\\\E=400\ W-h\\\\or\\\\E=0.4\ kWh[/tex]

So, 0.4 kWh of energy would be needed.

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”.
