Answer:
Displacement is a vector quantity
Explanation:
Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion.
Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
Answer:
1.8 m/s
Explanation:
momentum = mass × velocity
initial momentum = m1v1+m2v2
= 3×3 +2×0 = 9+0= 9 kg m/s
let combined velocity be V
HENCE
final momentum = total mass × velocity
= (3+2) × V = 5V
According to law of conservation of momentum
final momentum = initial momentum
5V = 9
V =9/5
V = 1.8 m/s
Answer:
C
Explanation:
When a ball rolls down a hill, Potential Energy Conversion takes place to Kinetic Energy.
The answer is to the question is strong and has a long range. The appropriate response is Strong, short range. The nuclear force is a compel that demonstrations between the protons and neutrons of particles. Neutrons and protons, both nucleons, are influenced by the atomic drive indistinguishably.
