Answer:
potential energy is a stored energy or energy of position (gravitational).
Kinetic energy is a energy of motion.
Explanation:
in the formula K is for the kinetic and the P stand for the potential.
The answer is real and smaller than the object. The image point of the top of the object is the point where the two refracted rays intersect. Tracing the entire image having the same distance from the mirror as the image of the top of the object and with the bottom on the principal axis. Hence, a real inverted image will be formed for an object outside the focal point.
Answer:
Matching of Part A with Part B
Rutherford ------------ discovered proton nucleus
Bohr----------------------postulated the quantum atom
Dalton-------------------Father of atomic theory
Chadwick --------------discovery of neutron
J.J. Thomson----------discovered the electrons
hence , the matching will be
2 -- d
3 -- e
4 -- b
5 -- a
6 -- c
