What is the orbital velocity of Miranda around Uranus? (Hint: Use the formula for circular orbit velocity: , where . The formula requires input quantities in and . The mass of Uranus is ; the distance from Miranda to Uranus is .)

The orbita velocity of miranda around uranus is V = 6.66 km/s

Explanation:

The formula for circular orbit velocity is V = Sqrt(GMR)

The mass of uranus = 8.681 × 10^25 kg

The distance from miranda to uranus = 129,390 km

G = 6.674×10−11 m3⋅kg−1⋅s−2

Inserting the parameters above into the equation V = Sqrt(GMR)

V = 6.66 km/s

real, smaller and upside-down.   so the answer should be b.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
