You need to divide the motion into its component: vertical and horizontal motion.
The time taken to fall vertically from the cliff is equal to the time taken to move horizontally.
Using the vertical component, which is an accelerated motion with an initial velocity equal to zero, we can solve for t:
h = 1/2 · g · t²
t = √(2·h / g)
= √(2·50 / 9.8)
= 3.2 s
Horizontally, it is a constant motion:
d = v · t
= 20 · 3.2
= 64 m
The ball will strike the ground at a distance of 64 meters from the cliff.
Answer:
Pauli exclusion principle
Explanation:
Pauli's exclusion principle speaks to the quantum numbers assigned to an electron to describe it's general position and movement. Two electrons can occupy the same energy level (which is described by the first quantum number-the principal quantum number), the orbital angular momentum quantum number (represented by the second number) and magnetic quantum number. electrons that have the same value for all three numbers will have different spins. one will have positive a half while the other has negative a half. Therefore they will never have the same complement of quantum numbers
If the speed of the particle is doubled. Then the value of the momentum also gets doubled.
<h3>What is momentum?</h3>
The sum of an entity's speed and mass is known as its linear momentum, translational momentum, or simply momentum in Newton's laws of motion. It has both a magnitude and a direction, making it a vector quantity. The SI unit of momentum is kg-m / s.
Let m be the mass and v be the velocity of an object. Then the momentum is given as,
P = mv kg-m / s
A particle is moving at a speed less than c / 2. If the speed of the particle is doubled.
P = m(2v)
P = 2mv
If the particle's speed is twice. The momentum's value is then increased by two.
