Suppose I had a tower that stood two Earth radii tall from the surface of the Earth to the top I start on the ground with a scal

e and big rock (I'm also a geology fan.) I weigh the rock and it's 90 lbs. Then I take the rock and the scale on an elevator and go up to the top of the tower. There I weigh the rock again. How much does the rock weigh up at the top of the tower.

Answer: The rock would still weigh 90lbs

Step-by-step explanation:

No, weight has being proven to reduce by the further you move from the center of the Earth. But since even the tallest buildings in the world or tallest mountains are a tiny fraction of the Earth’s radius, the difference in weight won’t be something that can be measured as it’s a tiny fraction. So the mass of the rock doesn’t change what changes is the gravitational force ( g ). So the rock would still end up weighing 90lbs even at the top of the tower because it is still within the earths atmosphere.

Which equations show inverse operations of each other? Choose exactly two answers that are correct. 16×1/4  =4     1/4 ÷4 =116  
qaws [65]

Answer:

6 × 1/4 = 4

4 × 1/4 = 1

4 ÷ 1/4 = 16

All three of these are correct

Step-by-step explanation:

16 × 1/4 = 4

16/4 = 4

4 = 4


1/4 ÷ 4 = 116

1/4 × 1/4 = 116

1/16 ≠ 116


4 x 1/4 = 1

4/4 = 1

1 = 1


4 ÷ 1/4 = 16

4 × 4 = 16

16 = 16

Two less than 2 times a number is the same as the number plus 64. What is the number?
Alex Ar [27]
Set it up as an equation. "A number" is x.

2x-2=x+64

Move all of the x terms to one side by subtracting x from both sides, then add 2 to both sides to isolate x.

X=66

The number is 66

A satellite travels from Earth to the moon (238,905 miles), then from the moon to Mars (48,340,732 miles) and finally from Mars
hodyreva [135]

The total distance the satellite traveled in all is 120,528,469 miles

<h3>Calculating total distance</h3>

From the question, we are to determine how far the Satellite traveled in all

From the given information,

A satellite travels from Earth to the moon (238,905 miles),

and

It traveled from the moon to Mars (48,340,732 miles)

and

It finally traveled from Mars to Venus (71,948,832 miles)

The total distance the satellite traveled in all = 238,905 miles + 48,340,732 miles + 71,948,832 miles

∴The total distance the satellite traveled in all = 120,528,469 miles

Hence, the total distance the satellite traveled in all is 120,528,469 miles
