A rubber ball is dropped from the top of a ladder. It bounces on the same spot on the ground several times, each time to a lesser height than the previous bounce, before coming to rest in place.
In one or two sentences, explain how the experiment shows the direction that gravity pulls an object, specifically showing that it does not pull an object parallel to the ground.

Here to help! :)
Explanation:
Firstly you need to know what is gravity?
Explanation:
The size of the gravitational force is proportional to the masses of the objects and weakens as the distance between them increases. Both objects exert an equal attractive force on each other: a falling object is attracting the Earth with the same size force as the Earth is attracting it.
Now you need to know why a rubber bounce?
When a rubber ball hits something, it absorbs energy and releases energy really fast, Zheng said. ... When it hits something, it stops, and the kinetic energy is stored inside the ball as internal energy. Then it can quickly convert the internal energy back into kinetic energy which allows the ball to bounce back
Now you want to know why does a rubber bounce lower each time?
The rubber slows down, deforms temporarily and shoots back up. The air in the ball acts like a spring—it gets compressed and expands again. During the collision, some of the rubber's's energy is converted into heat. As a consequence, the ball shoots up with less energy than it had when it reached Earth.
If you think this was helpful give me brainliest please! Have a great day.
Gravity does not pull the object to the ground, but pulls it towards the object with the greatest mass.
We can arrive at this answer because:
Gravity is a force that is related to mass and distance between objects.In that case, the more mass an object has, the more will be the "power" of gravity over it.The object with more mass, then, can attract the object with less mass towards it, due to gravity.In this case, a rubber ball has less mass than planet Earth. For this reason, we can say that the planet Earth, through gravity, can attract the rubber ball with great intensity.Therefore, the rubber ball is not being pulled towards the ground, but rather towards the planet Earth.

As the French and British empires in North America grew, conflicts arose between the two nations. In 1754, fighting broke out between the British and French over western land around the Ohio River. That year, troops led by George Washington marched to the Ohio River to drive out the French. The French and their Native American allies easily defeated the American troops. This battle marked the beginning of the French and Indian War.
For the next several years, fighting continued between British and French forces to determine who would rule North America. The French beat the British during much of the early fighting. Then, in 1757, the English King appointed William Pitt to the government. Under Pitt's leadership, the British began winning battles.
The British arm's victories prompted the powerful Iroquois Indians to support them. this agreement gave Britain some Native American allies to balance those of France.
In 1775, the British forces defeated the French at Quebec. With this victory the British had won the war. The two nations signed a peace treaty signed in 1763. .As a result of the Treaty of Paris, France gave up

Hope this helps :)
pls make brainliest :p
Martin Bucer and Wolfgang Capito, two of Strasbourg's most prominent reformers, extended an invitation to Calvin to oversee a church of French exiles there. Calvin initially declined the offer because Farel was left out, but he changed his mind after Bucer made a plea to him.
What did John Calvin do in Geneva?Calvin compiled a comprehensive list of strict moral guidelines while he was living in Geneva. These included harsh no-dancing rules even at weddings, as well as bans on fornication, gambling, and profanity. Penalties applied for unexcused absences from religious services. The death penalty is an option for murder and adultery.
He had to take a detour to the south, which brought him to Geneva, as a result of military maneuvers by the imperial and French soldiers. William Farel, a fellow French reformer who lived in the city, urged Calvin to stay and help him in his efforts to reform the church there. Calvin had only expected to stay for one night.
Thus, Martin Bucer and Wolfgang Capito, two of Strasbourg's most prominent reformers.

What modern U.S. foreign affairs issues and/or concerns are likely long-term results of Taft's dollar diplomacy
approach to foreign policy?
Answers
Answer:
Under the name of Dollar Diplomacy, the Taft administration engineered such a policy in Nicaragua. It supported the overthrow of José Santos Zelaya and set up Adolfo Díaz in his place; it established a collector of customs; and it guaranteed loans to the Nicaraguan government.
Modern U.S. foreign affairs issues and/or concerns are likely long-term results of Taft's dollar diplomacy approach to economic instability in framing foreign policy.
What is Dollar diplomacy?In addition to allowing the United States to profit financially from other nations, Taft's dollar diplomacy also prevented other foreign nations from making any form of profit. As a result, when the United States benefited from other nations, other superpowers were unable to experience the same advantages.
In an endeavor to utilize foreign policy to secure markets and opportunities for American firms, to "substitute dollars for bullets."
Further Immigration, poor salaries, a change in property ownership, a breakdown of the family unit, an increase in population, and illegitimate births were all consequences of dollar diplomacy.
Some of the problems caused by Taft's policies materialized right away, while others would not show their effects for many years. Huge debts in the region led to years of economic instability and fueled nationalist movements fueled by hatred of American meddling in the area.
Thus this policy led to economic instability.
