Velocity is the speed at which an object moves in a specific direction. It's measured in meters per second, minute or hour in a particular direction—like miles per hour going north, kilometers per minute west or meters per second up. Velocity tells us both the speed and direction we are traveling. Acceleration is a change in velocity. It's measured by subtracting the object's starting velocity from the final velocity, divided by the time this change in velocity took. We usually think of acceleration as speeding up, but it can also mean slowing down. We call this negative acceleration or deceleration. If a car was driving 45 miles per hour northeast, and is now driving 30 miles per hour north, A the car’s velocity decelerated. B the car’s velocity accelerated. C the car’s velocity remained unchanged. D the car’s acceleration is 30 miles per hour.

Explanation:

The Scientific Revolution

The Scientific Revolution took place during the 16th and 17th centuries. Many cultures influenced the beginning of the Scientific Revolution,

including Greek Jewish, Christian, and Muslim cultures.

In the ancient world. Greek was the language of science. Greek sharply decreased in usage as the Roman Empire expanded and the use of Latin

became more widespread. During the Renaissance, scholars became increasingly interested in classical ideas and philosophy. They studied Greek

again and were able to translate texts that had been otherwise lost.

Also, due to the Medieval Crusades, Europeans began to have more contact with the Middle East. As a result, the Western

world benefited greatly

from contact with Islamic cultures. Knowledge of science, medicine, and even architecture were shared between the two cultures.

In addition to the sharing of ideas between Europe and the Middle East, the humanism movement of the Renaissance furthered the Scientific

Revolution. This European humanist movement focused on human potential. The movement valued logical reasoning and observation over the

Christian values of humility and passivity. This movement developed from the rediscovery of Greek and Latin texts.

Finally, global exploration also served as a springboard for the Scientific Revolution. As explorers came back from the New World and Asia, they

shared new information and new goods. People became curious about the knowledge and the practices of other cultures. People wanted to know

even more about the world and how it worked.

explanation:

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
