Answer:

The force of gravity between two objects will decrease as the distance between them increases. The two most important factors affecting the gravitational force between two objects are their mass and the distance between their centres. As mass increases, so does the force of gravity, but an increase in distance reflects an inverse proportionality, which causes that force to decrease exponentially.

Hope it helps pls mark me as BRAINLIST thanks:)

Juan is on a morning jog. His speed is represented in the graph. At what rate of speed is Juan running between 4min and 6min? Ac

Nesterboy [21]

Answer:

a) The speed of Juan is 250 m/min

b) In that interval, he's at rest

c) Juan would have needed 12 minutes to run 3000 m

Explanation:

Distance vs Time Graph Analysis

If time is on the horizontal axis, and the distance is in the vertical axis, then the slope of the graph represents the instantaneous speed of the moving object. The graph shows three different zones which reflect Juan's jogging at that morning.

a) The period between 4 and 6 minutes clearly shows Juan is moving in such a way the distance increases when time passes. The speed of the motion can be obtained by computing the slope of the line. We can locate the points (4,1000) and (6,1500). We compute the speed

$\displaystyle v=\frac{1500-1000}{6-4}=\frac{500}{2}=250 m/min$

The speed of Juan is 250 m/min

b) We can see between 7 and 11 minutes, Juan's distance is not changing because he stopped running. In that interval, he's at rest

c) We have already determined the speed on the first 7 minutes (the same as between 4 and 6 minutes). We know that

$\displaystyle v=\frac{x}{t}$

Where v is the speed, x is the distance, and t is the time

We need to know the time needed to travel x=3000 m at the initial speed v=250 m/min, so we solve the equation for t

$\displaystyle t=\frac{x}{v}$

$\displaystyle t=\frac{3000}{250}=12\ minutes$

Juan would have needed 12 minutes to run 3000 m

Why do opaque materials become warmer when light shines on them?

gavmur [86]

Opaque materials absorb all the light that shines on them. None of it comes out the other side. That's why they're opaque.

Opaque materials become warmer when light shines on them, because they absorb the energy carried by the light that shines on them. (According to the law of Conservation of Energy, that energy has gotta go somewhere.)

Galileo estimated the height of lunar mountains by: (A) measuring the height of clouds around the mountains (B) measuring the wa

quester [9]

Answer:

Option (D) By observing illuminated mountain peaks in the dark portion of the moon.

Explanation:

Unlike the traditions at the time of Aristotle which considered that the celestial bodies are spherical and perfectly smooth bodies.

But based on Galileo's observations, the zone that was illuminated in the dark region of the moon near the line that separates the illuminated and the shadowy parts, known as terminator was noticed.

On the breaking of the dawn, as the sunlight hit the top of the lunar mountains it lightens up while the valleys are still dark.
