Planet RMM-1 has a mass of 28,500 kg and the star it revolves around has

SOVA2 [1]

Gravitational force = G · (mass₁) · (mass₂) / (distance)

(distance²) = G · (mass₁) · (mass₂) / (Gravitational force)

G = 6.67 x 10⁻¹¹ n-m² / kg² (the "gravitational constant")

Distance² = (6.67 x 10⁻¹¹ n-m² / kg²) (28,500 kg) (2.2 x 10⁸ kg) / (39 N)

Distance² = (6.67 · 28,500 · 2.2 x 10⁻³ N-m²) / (39N)

Distance² = (418.209 N-m²) / (39N)

Distance² = 10.72 m²

<em>Distance = 3.275 meters</em>

An absurd scenario, but that's by golly what the math says with the numbers provided. I guess it's a teeny tiny planet orbiting 3.275 meters outside a teeny tiny black hole.

A pilot took 1/2 hour to complete 1/3 of his trip. How much longer will it take him to complete his trip?

katen-ka-za [31]

Answer: The answer is 1.5 hours.

Step-by-step explanation: Given that the pilot took 1/2 hour to complete 1/3rd of his trip. We are to calculate the time that he will take to complete his trip.

Time taken by the pilot to complete 1/3 rd of his trip = 1/2

Therefore, time taken by the pilot to complete his trip is given by

$t=\dfrac{1}{2}\times 3=1.5.$

Thus, the pilot will take 1.5 hours to complete his trip.

Is the force of gravity stronger on a piece of paper when it is crumpled? is the force of gravity stronger on a piece of iron th

Kipish [7]

No, gravity pulls every object with the same force irrespective of its shape, size place etc.

Therefore the force of gravity on the iron and wooden piece of same mass is same. Also the force of gravity is same on the crumpled piece of paper as that of plain paper.

Force of gravity is always same.

How much heat must be removed from 200 pounds of blanched vegetables at 189 degrees F to freeze them to a temperature of 22 degr

Virty [35]

To solve this problem it is necessary to apply the concepts related to heat exchange in the vegetable and water.

By definition the exchange of heat is given by

$Q =mc\Delta T$
