Answer:

<em>1.49 x </em>10^{11}<em></em>

<em></em>

Explanation:

Kepler's third law states that <em>The square of the orbital period of a planet is directly proportional to the cube of its orbit.</em>

Mathematically, this can be stated as

T^{2} ∝ R^{3}

<em>to remove the proportionality sign we introduce a constant</em>

T^{2} = kR^{3}

k = \frac{T^{2} }{R^{3} }

Where T is the orbital period,

and R is the orbit around the sun.

For mars,

T = 687 days

R = 2.279 x 10^{11}

for mars, constant k will be

k = \frac{687^{2} }{(2.279*10^{11}) ^{3} } = 3.987 x 10^{-29}

For Earth, orbital period T is 365 days, therefore

365^{2} = 3.987 x 10^{-29} x R^{3}

R^{3} = 3.34 x 10^{33}

R =<em> 1.49 x </em>10^{11}<em></em>

What is the kinetic energy of a 1200 kg object that is moving at a speed of 24m/s?
n200080 [17]
Here, K.E. = 1/2 * mv²

So, K.E. = 1/2 * (1200) * (24)²

K.E. = 1/2 * 1200 * 576

K.E. = 600 * 576

K.E. = 345,600 J

Hope this helps!

Una pelota de voleibol de 0.45 kg es impactada (golpeada) por una fuerza de 80 N. ¿ Cuál es la aceleración que experimenta la pe
KIM [24]

Answer:

a = 177.77 [m/s^2]

Explanation:

Este es un problema relacionado con la segunda ley de Newton. La cual nos dice que la sumatoria de fuerzas aplicada sobre un cuerpo debe ser igual al producto de la masa por la aceleración.

De esta manera tenemos:

F = m*a

F = fuerza = 80 [N]

m = masa = 0.45 [kg]

80 = 0.45 * a

a = 80 / 0.45

a = 177.77 [m/s^2]
