Question

which s like a miniature solar system. Maybe t applies to the real solar system! consider the planet venus, which orbits the Sun at a distance ofo.7 AL in a 10d oro. 5. uantum Mechanics applies to the atom Earth years (1 AU 1.496e8 km) (a) What is the velocity of this planet around the Sun? km/s (b) Venus has a mass of 4.8685 x 1024 kg. What is the angular momentum of Venus around the Sun? 1.84e40 kg"m2/s (c) what multiple of is this? Is the result an integer or a non-integer, or is it impossible to tell? You rs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. h Enter a number

Explanation / Answer

Here,

a) for the speed of planet

speed of planet = distance/time taken

speed of planet = 2pi * (0.7233 * 1.496 *10^8)/(0.6151 * 365 * 24 * 3600)

speed of planet = 35.04 km/s

the speed of planet is 35.04 km/s

b)

angular momentum = m * v * r

angular momentum = 4.8685 * 10^24 * 35.04 *10^3 * 0.7233 * 1.496 *10^8 * 10^3

angular momentum = 1.85 *10^40 Kg.m^2/s

c)

multiples of hcross = 1.85 *10^40/(h/(2pi))

multiples of hcross = 1.85 *10^40/(6.634 *10^-34/(2pi))

multiples of hcross = 1.75 *10^74

it is impossible to tell as we have to find this value to 74 significant figures then
