Answer:
Quantum mechanics was one of the two great revolutions in modern physics. The first, or Einstein's relativity, was in fact the pinnacle of classical physics. But quantum mechanics and related theories completely changed the world of science and philosophy, and it was the end of classical physics.
Like Einstein relativity, we all use quantum mechanics on a daily basis, but its mathematical principles are very complex and beyond the reach of ordinary people without a degree in physics or mathematics.
In this post, I have tried to make this theory more accessible to all interested loved ones by stating the quantum theory and its consequences for the public.
Most of the mass of an element is found in the NUCLEUS
Answer:
The rotor's angular velocity is 82.73rad/s
Explanation:
It is a curvilinear movement of a constant radius. If there is uniform angular acceleration, then it is a circular motion with constant acceleration, whose equations are analogous to that of the translational motion.
Calculating the initial velocity of the rotor, V1 in rad/s
V1 = 610rev/minute × 6.28 × 1miute/60secs
V1 = 63.85rad/s
Using kinematic equation to calculate the final velocity of the rotor
Given:
Angular acceleration = 5.9rad/s^2
Time,t= 3.2seconds
V2 = V1 + a × t
V2 = 63.85 + (5.9)× (3.2)
V2 = 63.85 + 18.88
V2 = 82.73rads/s
Answer:
Velocity of wave = 2322 m /sec
Explanation:
We know that, Velocity of wave v = n λ
Given, n
= 540 Hz, λ=4.3 m
, v = ?
Putting the value of n and λ
Velocity of wave = 540 x 4.3 = 2322 m /sec
