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:
The truck
Explanation:
Kinetic energy is directly proportional to mass. Since the truck has more mass, it will have more energy.
Apparent depth is dangerous for swimmers because
<span> When you look vertically downwards into a </span>swimming<span> pool full of water the bottom seems closer than it. </span>If the pool is really deep and it doesn't look deep to you that's not good cuz if you don't know how to swim in deep water you might drown.
Hope this helps ;)
