The classical physics works on the Newton's laws of motion. It is applicable on heavenly bodies which are governed by the gravitational force. On the other hand, Quantum Physics is applicable for very low mass and sized bodies like electron, protons etc. The classical physics would accurately describe the motion of satellite moving with speed 7500 m/s using the following formula:
where G is the gravitational constant, M is the mass of the planet and v is the orbital speed. Then radius of the orbit can be described by this formula.
B. The atomic number of zirconium is 40.
Answer:
The are moving with a speed of 25 m/s after the collision.
Explanation:
assuming the mass (m) of the cars are equal, let v = 20 m/s be the velocity of the driver in the front and u = 30 m/s be the velocity of the driver behind. let V be the velocity of the cars after the collision.
then, by conservation of linear momentum:
m×(v + u) = V×2×m
(v + u) = V×2
V = (v + u)/2
= (20 + 30)/2
= 25 m/s
Therefore, the are moving with a speed of 25 m/s after the collision.
A philosophical theory or approach that emphasizes that the existence of the individual person as a free and responsible agent determining their own development through acts of the will.
