Studying energy involves determining the amount of energy an object has. This energy can be kinetic or potential, or it could be a combination of both. Consider a 2-kg bowling ball sits on top of a building that is 40 meters tall. It falls toward the ground. Think about the amounts kinetic energy the bowling ball has as it falls, select the when the ball would have the most kinetic energy from the choices given. Question 1 options:

A. as it is just about to hit the ground from a fall off a building that is 40 meters tall and traveling 28 meters per second.

B. as it is half way through a fall off a building that is 40 meters tall and traveling 19.8 meters per second.

C. as it sits on top of a building that is 40 meters tall.

D after it hits the ground and is no longer moving.

did anyone actually do this? like if anyone has submitted this i rly need .

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
