If the diatomic molecule consists of atoms from two different elements, then it is a heteronuclear diatomic molecule. There are seven elements that naturally occur as homonuclear diatomic molecules in their gaseous states: hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine.
The kinetic energy of a 750 kg car moving at 50.0 km h is 72300 joules.
Given,
mass of car (m)= 750 kg
speed of car (v)= 50 km/h
= 50 x 5/18
= 13.9 m/s
we know that kinetic energy= 1/2 x m x v*v
= 1/2 x 750 x 13.9 *13.9
= 72300 joules
so the kinetic energy is 72300 joules.
Energy is the capacity of an object to do work, and like work, energy's unit is the joule (J). Energy exists in many different forms, but the one we think of most often when we think of energy is kinetic energy. Kinetic energy is often thought of as the energy of motion because it is used to describe objects that are moving.

B. a solar storm that moves across the sun's surface
Answer:. The acceleration of the object is directly proportional to the force and inversely proportional to the mass.
Explanation:
According to Newton s Second Law of Motion, also known as the Law of Force and Acceleration, a force upon an object causes it to accelerate according to the formula net force = mass x acceleration.
The answer to this question should be a gravitational force.
A gravitational force is something that sort of attracts two things of mass. This force must never ever pull the objects of mass apart. It must always try to pull them together. So, judging by the question we can tell that the two masses in this situation are the leaf and the ground. When the leaf fell on the ground this was the gravitational force pulling the leaf down so it connects with the ground.
