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.
Lessening frictions Means it harder to stop
Answer:
the safe's coefficient of kinetic friction on the bank floor is
Explanation:
GIven that:
Bonnie and Clyde are sliding a 325 kg bank safe across the floor to their getaway car.
So ,let assume they are sliding the bank safe on an horizontal direction
Clyde → Δ(bank safe) → Bonnie
Also; from the above representation; let not forget that the friction force is acting in the opposite direction ←
where;
=
The safe slides with a constant speed
If Clyde pushes from behind with 377 N of force while Bonnie pulls forward on a rope with 353 N of force.
Thus; since the safe slides with a constant speed if the two conditions are met; then the net force acting on the slide will be equal to zero.
SO;
Since the net force acting on the slide will be equal to zero.
Then;
Also; let and
Then;
where;
Then;
Thus; the safe's coefficient of kinetic friction on the bank floor is
WARMER AND WETTER BIOMES GENERALLY HAVE MORE PLANTS, WHICH NEED MORE SUNLIGHT. THE SUNLIGHT CONTRIBUTES TO THE HIGHER NET PRODUCTIVITY
Answer:
100 newtons
Explanation:
Given,
Jamal pushing a large box by a force, F = 100 N
Work done on the large box is, W = 0
It is because the applied force is less than the force of the friction between the two surfaces.
Yet, there will be a force that is exerted by the large box on Jamal.
According to newton's third law of motion, every action has an equal and opposite reaction. The reaction force is in the direction opposite to the force of action. But, their magnitude remains the same.
Hence, If the action force is 100 N, then the reaction force should be in 100 N
