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
A. Move the candle to the right, or the focal point to the left.
For a convex lens, the closer an object is to the focal point, the larger it’s image is (and therefore the greater the magnification is). The two ways you could make the candle be closer to the focal point are to move the candle to the right, or the focal point to the left.
It is true that a physical change occurs when a material changes shape or size, but the composition of the material does not change. The correct answer is True.
Answer:
≅3666.67 N
Explanation:
Use Newton's 2nd law, F = ma where F=force applied, m = mass of the object,
a = acceleration acquired by the object.
a= (v-u)/t where v = final velocity, u = initial velocity and t = time taken
calculate a = (30-0)/9 ≅ 3.33 m/s2
Then F = 1100×a = 3666.67 N
