Answer:

Explanation:
The energy of a photon is given by:

where
is the Planck constant
is the speed of light
is the wavelenght of the photon
For the microwave photons in this problem,

so their energy is

<span>Balloons are blown up, and then rubbed against your shirt many times. The balloon then touches the ceiling. When released, the balloon remains stuck to the ceiling. The balloon is charged by contact. The ceiling has a neutral charge. The charged balloon induces a slight surface charge on the ceiling opposite to the charge on the balloon. Balloon and ceiling electric charges are opposite in sign, so they will attract each other. Since both the balloon and the ceiling are insulators, charge can not flow from one to the other. The charge on the balloon is fixed on the balloon and the charge on the ceiling remains fixed to the ceiling. It just so happens that the<span> electrostatic force the ceiling exerts on the balloon is sufficient to hold the balloon in place (i.e. overcomes gravity, etc.).</span></span>
<h3><u>Answer;</u></h3>
Universe, galaxy, solar system, planet, moon
<h3><u>Explanation;</u></h3>
- <u>A galaxy</u>, such as our Milky Way Galaxy, is a collection of solar systems orbiting around a central core.
- <u>A solar system</u> consists of a star, normally the sun and all of its planets, asteroids, comets and other bodies.
- <u>A planet</u> is a nearly spherical body which is in orbit around the Sun. Planets are larger than moons.
- <u>Moons</u> are typically rocky bodies which are in orbit around planets.
Answer:
λ = 5.65m
Explanation:
The Path Difference Condition is given as:
δ=
;
where lamda is represent by the symbol (λ) and is the wavelength we are meant to calculate.
m = no of openings which is 2
∴δ= 
n is the index of refraction of the medium in which the wave is traveling
To find δ we have;
δ= 
δ= 
δ= 
δ= 
δ= 
δ= 
δ= 82.15 -73.68
δ= 8.47
Again remember; to calculate the wavelength of the ocean waves; we have:
δ= 
δ= 8.47
8.47 = 
λ = 
λ = 5.65m
