I believe the correct answer from the choices listed above is option B. The scientist most often credited with the idea that matter can have wave-like properties is de Broglie. He <span>related E=mc^2, E=hf and p=mv in order to acquire the de Broglie wavelength, whose formula λ=h/p where h is Planck's constant and p is momentum of the particle.</span>
Answer:
3 : 08 : 10.9
Explanation:
assuming a 12 hour clock
angular velocity of the hour hand is 2π/(3600(12)) rad/s
angular velocity of the minute hand is 2π/3600 rad/s
difference is 2π/3600 - 2π/(3600(12)) = 11(2π/(3600(12)) rad/s
45° = π/4 radians
This angle is covered in a time of
π/4 rad / 22π / (3600(12)) = 900(12) / 22 = 490.909090... s
or about 8 minutes 10.9 s
ANSWER 3:08:10.9
The period is 2 seconds.
A period is a time taken to make one simple harmonic motion. It can be described as time divided by how many waves do. We can write the period formula as
T = t / n
where T is period, t is time and n is the amount of simple harmonic motions.
From the question above, we know that the mass travel up and down, it means that the cycle is one simple harmonic motion.
n = 1
t = 2s
Hence
T = t / n
T = 2 / 1
T = 2 second

The tendency mass- less object to resist a change in its motion
The correct answer is B (Inertia)
We define inertia as the resistance to change of the state of motion. That is, a body tends to remain in its state of motion or rests unless an external for acts on it. The quantity depends on the mass of the body. If the body is heavy, it requires a large force to overcome the inertia.
