Answer:
P = 800 Pa
Explanation:
The pressure of water at the bottom of the pot can be given by the following formula:
where,
P = Pressure at the bottom of the pot = ?
ρ = density = 1000 kg/m³
h = height of water = 8 cm = 0.08 m
Therefore,
<u>P = 800 Pa </u>
The displacement covered by the worker in the whole trip is 30km.
The easiest way to solve this problem is using the displacement equation:
Δx = x₂ - x₁
A worker covers a distance of 40 km from his house to his place of
work, and 10 km towards his house back. So:
Δx = x₂ - x₁ = 40km - 10km = 30km
Answer:
we would have no oxygen and barely any water.
Answer:

The speed of the wave is
The wavelength of the wave is mathematically evaluated as
substituting values
The wave number is mathematically represented as
substituting values
The general form of wave function is
given that the amplitude is
While which is the angular velocity is represented as
and k which is the angular wave number is mathematically represented as
The wave function becomes
substituting values
