Answer:
A) Greater than the attraction between two small objects the same distance apart.
Explanation:
The gravitational force between two objects is:
F = GMm / r²
where G is the gravitational constant,
M is the mass of one object,
m is the mass of the other object,
and r is the distance between the objects.
If the distance is the same, then two large objects will have a larger gravitational force between them than two small objects.
15km = 15,000m
1/2h = 1800s
15,000 / 1,800 = 25/3ms^-1
Answer:
appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity
Explanation:
3. Football: The first law takes place before the snap. When the quarterback is still calling out his play, everyone including the ball, are still. The ball remains motionless until it is acted upon by the center. The center flings the ball back to the quarterback causing it to go into motion, then remains motionless until the quarterback throws the ball to a wide receiver for a touchdown. When the defensive lines meet, the heavier players such as New England's Vince Wilfork, require much more force applied to them to move them out of the way than it would to hit Julian Edelman which explains the second law. This can also explain the third law as well. When one defensive line pushes against another, they both apply force to each other and if they are the same strength, the reaction for one lineman is the others opposite re-action
Answer:
A. If two objects collide, each object exerts a force in the same direction as the other.
