What power output is required of a motor that needs to lift a 450 kg elevator car 12 meters in 8.0 seconds?\
Answer:
[tex]Power = 6.62kw[/tex]
Explanation:
Given
[tex]Mass = 450kg[/tex]
[tex]Height = 12m[/tex]
[tex]Time = 8s[/tex]
Required
Determine the power output required
First, we calculate the energy used to lift the object.
To do this, we make use of potential energy formula:
[tex]Energy = mgh[/tex]
Where
[tex]g = 9.81m/s^2[/tex]
So, we have:
[tex]Energy = 450 * 9.81 * 12[/tex]
[tex]Energy = 52974J[/tex]
The power output is then calculated as:
[tex]Power = \frac{Energy}{Time}[/tex]
[tex]Power = \frac{52974}{8}[/tex]
[tex]Power = 6621.75W[/tex]
Convert to kilowatt
[tex]Power = \frac{6621.75kW}{1000}[/tex]
[tex]Power = 6.62175kW[/tex]
[tex]Power = 6.62kw[/tex] --- approximated
Hence, the power output is 6.62kw
Using the power formula, the required power output needed to lift the load is 6.615 Kw
Given the Parameters :
Mass of car = 450 kg Distance = 12 meters Time taken = 8 secondsRecall :
Power = (Workdone ÷ Δtime) Workdone = Force × Distance ; Force = mg ; g = Acceleration due the gravity, = 9.8 m/s²Hence,
Power = [(mgh ÷ t)]
Power = [(450×9.8×12) ÷ 8]
Power = 52920 ÷ 8
Power = 6615 watt
Hence, the power output required is 6615 watts = 6.615 Kw

What is true about the inertia of two cars, Car A of mass 1,500 kilograms and Car B of mass 2,000 kilograms?
OA.
Car A and Car Bhave the same inertia.
B.
Car A has more inertia than Car B.
Oc.
Car Bhas more inertia than Car A.
ОО
D.
Both the cars have negligible inertia.
Answer:
Car B has more inertia than Car A.
Explanation:
Inertia of a body is the property to oppose its state of rest or state of uniform motion. It is also equivalent to the measure of its mass. Newton's first law of motion is also called as law of inertia.
According to your question, we have to mention the name of car that has more inertia. So, the body having more mass will have more inertia.
The mass of car A is 1500 kg while the mass of car b is 2000 kg. Hence, car B will have more inertia.
What did the survey of 1979, showing the huge increase in probation officers' duties, indicate about the status of probation in this country? Probation worked only for juveniles. Judges no longer supported the probation system. Probation officers had too much work and too little funding. Other studies supported incarceration for preventing criminals in a return to crime.
Answer:
Other studies supported incarceration for preventing criminals in a return to crime.
Explanation:
Hello. You did not show the text to which this question refers, which makes it difficult for it to be answered. However, after extensive research it was possible to conclude that there are many studies that claim that incarceration prevents criminals from committing crime again. This is because imprisonment promotes social isolation, where the prisoner is unable to promote crime in any sphere of society. In addition, the prisoner is constantly watched, something that does not happen on conditional freedom.

lee Isaías 25,6-10 y encuentra dos comparaciones entre el banquete que describe
el profeta y la gloria que nos espera .
comparación 1
comparación 2
La respuesta correcta para esta pregunta abierta es la siguiente.
Pues revisando la información solicitada, podemos hacer las siguientes comparaciones.
1.- En ese versículo, el profeta Isaías hace referencia a la metáfora de la montaña, en donde existe un gran banquete para los elegidos de Dios en la cima. Habla de las delicias que le esperan a los fieles de Dios como recompensa a sus acciones. Algo así como el premio del señor después de una vida entregada a él.
Podemos encontrar una idea similar, pero ésta se encuentra en el Nuevo Testamento, en el evangelio de Lucas, cuando el evangelista se refiere a que Jesús invita a los fieles a comer y gozar del reino de los cielos.
2.- La segunda comparación es cuando el profeta Isaías hace referencia a que Dios consolará a sus fieles en el cielo, después de la muerte. Ahí, dice Isaías, el humano ya no sentirá dolor ni sufrimiento como lo sentía en la Tierra.
De igual manera, en Corintios, dentro del Nuevo Testamento, se hace referencia a que Cristo vencerá a sus enemigos y reinará por siempre en el reino de los cielos, en donde el humano podrá vencer a la muerte como Jesús lo hizo.
