Answer:
Explanation:
As we know that diameter of hand crank is given as
Also the diameter of the shaft on which the rope is wound is given as
now we know that both are moving with same angular speed
so we will have
so we will have
4520.25/6.15
The answer is D
Once the stone leaves the passenger's hand, its horizontal acceleration
stops. Its horizontal speed after that is whatever horizontal speed it had
at the instant it was dropped.
Its vertical acceleration ... its total acceleration with respect to the rails,
is 9.8 m/s² straight downward ... the acceleration of gravity.
Answer:
The particle momentum, p
Explanation:
A particle's de Broglie's wavelength is an indication of the scale in length where the particle's wave-like properties are important. The symbol of de Broglie wavelength is λ or given as follows;
The de Broglie's wavelength formula is given as follows;
Where;
λ = The wavelength of the particle in meters
v = The velocity of the particle in meters/seconds
m = The mass of the particle in kilograms
p = The momentum of the particle
h = Planck's constant = 6.626 × 10⁻³⁴ J/Hz
Therefore, the alternative value that we must have to successfully determine the wavelength if the mass and velocity are unknown, is the momentum, p of the particle.
