I dont know i don’t understand
Answer:
The correct answer is option A.
Explanation:
Energy of the photon of an electromagnetic radiation is give by Planck's equation:

Where:
h = Planck's constant
c = speed of light
= Wavelength of the photon's radiation
Energy of photon of 800 nm monochromatic light


Energy per mole of photons:
..[1]
Energy of photon of 400 nm monochromatic light

Energy per mole of photons:
..[2]
[1] ÷ [2]



Answer:
That is false
Explanation:
Just because it moves faster doesn't mean that it can carry and bigger load.
Volume of O2 = 22.4 x moles of O2
= 22.4 x 1.2
= 26.88L
Answer:
3.63m/s²
Explanation:
Given parameters:
Mass of box = 8kg
Net force = 29N
Unknown:
Acceleration of the box = ?
Solution:
To solve this problem, we use Newton's second law of motion which is stated as;
Force = mass x acceleration
Acceleration =
=
Acceleration = 3.63m/s²
