An object moving in a circle is accelerating, even if it moves with a constant speed because the velocity changes.
<u>Explanation:</u>
The direction of an object changes constantly during its movement in circle at a constant speed. As the direction changes it results in changing the velocity of that object. This happens since velocity has direction and magnitude.as it is vector quantity.
An object will have acceleration only if a resultant force is acting on that body. When an object is moving in a circle, this resultant force is the centripetal force that is acting towards the center of the circle.
Answer:
Explanation:Egypt, country located in the northeastern corner of Africa. Egypt’s heartland, the Nile River valley and delta, was the home of one of the principal civilizations of the ancient Middle East and, like Mesopotamia farther east, was the site of one of the world’s earliest urban and literate societies.

After Alexander the Great conquered the region in 323 BCE, urban Egypt became an integral part of the Hellenistic world. Under the Greek Ptolemaic dynasty, an advanced literate society thrived in the city of Alexandria, but what is now Egypt was conquered by the Romans in 30 BCE. It remained part of the Roman Republic and Empire and then part of Rome’s successor state, the Byzantine Empire, until its conquest by Arab Muslim armies in 639–642 CE.

Explanation: idek
Answer:
Positive Pion, Negative Pion and Neutral Pion
Explanation:
Pi-meson or also known as pion is one of any of the three (3) subatomic particles which characterizes of being unstable of its nature. The charged pions
π+
and
π−
decay with a mean lifetime of 26.033 nanoseconds or 2.6033×10−8 seconds, and the neutral pion
π0
decays with a mean lifetime of 84 attoseconds (8.4×10−17 seconds).
