Solar-powered cars use energy from the Sun to work. A panel on the car absorbs light energy from the Sun, which then generates a

n electric current. This electric current, in turn, allows the car to move. Which shows the correct order of energy transformations that take place in a solar-powered car?

Hai vận động viên chạy trên cùng 1 đoạn đường, vận động
Vladimir [108]

Answer:

Pemain A

Explanation:

Mengingat data berikut;

Kecepatan pemain A = 12 m/s

Kecepatan pemain B = 36 km/h

Untuk menentukan siapa pelari tercepat di antara dua pemain;

Pertama-tama, kita harus mengubah kecepatan menjadi satuan standar pengukuran yang sama.

Jadi, mari kita gunakan pengukuran umum meter per detik.

Konversi:

36 km/h = (36 * 1000)/(60 * 60)

36 km/h = 36000/3600

36 km/h = 10 m/s

Kecepatan pemain B = 10 m/s

Oleh karena itu, dibandingkan dengan kecepatan pemain A; pemain A lebih cepat.

Una profesora de física que se encuentra en la tierra aplica un examen a sus estudiantes que están en una nave espacial que se d
GuDViN [60]

Answer:

t´ =  2,5 h

Explanation:

Dado que a velocidades "comparables" a la velocidad de la luz, los principios de la física deben ser tratados a la luz de los conceptos relativistas, es necesario aplicar el factor de Lorentz al tiempo que los estudiantes tomaran como base para la elaboración de su examen-

El factor de Lorentz  γ =  1 / √1 - (v²/c²)

En ese factor c es la velocidad de la luz y v es la velocidad a la que se mueve el móvil ( en este caso la nave espacial que va a 0,6 *c )

La otra consideración que hay que tomar en cuenta es que cuando se tienen dos sistemas inerciales con velocidades relativas comparables a la velocidad de la luz, las coordenadas espaciales ( y el tiempo que es la cuarta coordenada ) se relacionan según:

(Movimiento exclusivo en la dirección del eje x )

x´  =  ( x - vₓt )*γ      y´= y    z´ = z      t´  = ( t - vₓ/c² ) *γ

Donde las coordenadas s distinguen por ´ y sin ´ para identificar a los dos sistemas, luego entonces:

t´ ( tiempo en la nave espacial )

t´  = [ t  - (0,6*c/c² ] *γ    ⇒    t´ =  t - 0,36/c / √1 - (0.6*c)²/c²

Dado que   t = 2 h   y que la velocidad de la luz c es  300000 km/s expresada en horas es  300000*3600 = 108*10⁷,el numerador se puede aproximar a 2 horas

t´ =  2 /√ 64*10⁻²

t´ = 2 / 0,8  h

t´ =  2,5 h
