Answer:
= 6.848 × 10^-24 J
Explanation:
Energy of a photon may be given by the Formula;
E = hf or E = hc/λ where E is the c is the speed of light, h is the planks constant and λ is the wavelength.
The speed of light is 3 × 10^8 m/s, h is 6.626 × 10^-34 Js
Hence;
E = (6.62 × 10^-34 Js × 3× 10^8 m/s)/ 2.9 × 10^-2 m
=6.848 × 10^-24 Joules
Answer:
0.5429 m/s^2
Explanation:
velocity of waterjet = 18 m/s
diameter of water jet ( d ) = 4 cm = 0.04 m
mass of vertical plate(m) = 750 kg
<u>Determine the acceleration of plate when the jet first strikes ( i.e. t = 0 )</u>
first we will determine the impact force
F = β*A*V^2 ----- ( 1 )
where ; β = 1000 kg/m^3 , A = π/4 * d^2 , V = 18 m/s
input values into equation 1
F = 407.15 N
<em>finally determine the acceleration at t = 0 </em>
F = m*a
a = F / m = 407.15 / 750 = 0.5429 m/s^2
A thought experiment aims to promote speculative thinking, logical reasoning, and paradigm shifts. Thought experiments force us to address problems we find difficult to answer, which forces us out of our comfort zone. They highlight knowledge gaps and aid in recognizing the boundaries of what is knowable.
<h3>What are thought experiments?</h3>
Thought experiments are imaginative methods for examining the nature of things. They are employed for a variety of purposes in a number of disciplines, including physics, economics, history, mathematics, and philosophy.
A thought experiment is a test that we do in our minds. Here, we will imagine a specific scenario, consider some of its repercussions, and come to a broad conclusion.
Therefore, a thought experiment aims to promote speculative thinking, logical reasoning, and paradigm shifts. Thought experiments force us to address problems we find difficult to answer, which forces us out of our comfort zone. They highlight knowledge gaps and aid in recognizing the boundaries of what is knowable.
