Answer:
Explanation:
1. The gravitational force is related to the mass of each object.
This is true, the gravitational force between the two objects is directly proportional to the product of masses of two objects.
2. The gravitational force on a satellite is less at an altitude of 500 km above the Earth than at an altitude of 1000 km.
It is false, as the gravitational force between two objects is inversely proportional to the square of distance between them. The objects at more height has less gravitational force.
3. The gravitational force between the Earth and a person is constant, no matter how high the person is above the surface of the Earth.
It is false, because as we go on heights the value of acceleration due to gravity decreases.
Answer:
Option C
Explanation:
As we know, weight = mass x acceleration due to gravity.
Therefore, the alien would weigh more on Saturn as compared to Earth because the acceleration due to gravity is more on Saturn than Earth.

We have that for the Question "In the same year, the average finishing <em>time</em> for U.S. women was 4 <u>hours </u>and 41 <em>minutes</em>. What was the average female speed in miles per <em>hour</em>?" it can be said that
The average female speed in miles per hour
From the question we are told
In the same year, the <u>average</u> finishing <em>time</em> for U.S. women was 4 <u>hours </u>and 41 <em>minutes</em>. What was the average female speed in <u>miles</u> per <em>hour</em>?
<h3>Average speed </h3>
This is defined as the collective <u>mean</u> of different travel <em>intervals </em>
Generally the equation for Speed is mathematically given as
V=\frac{Distance}{Time}
Therefore
For 4 <u>hours </u>and 41 <em>minutes=4.683hours</em>
This travels time was <em>obtained </em>over a series of distance
<em>Hence</em>
<em>Distance D</em>
The average female <em>speed</em> in miles per hour

The specific gravity is how the density of the object compares to the density of water. Water's density is 1gram per milliliter. We just need to figure out the density of the object.
The object is .8 kg and it displaces 500mL of water, so the density is the mass divided by the volume. Since the density of water is given in grams, we have to convert the objects mass from kg to g and then we can get the density.
.8kg * 1000g/kg = 800 grams
So
800g/500ml = 1.6grams/mL this is the density.
So divide the density of your object by the density of water, which is 1g/mL, you get 1.6 as the specific gravity. This means the object is 1.6 times more dense than water.
