Answer:

E = 3.88 * 10^{-17} J

Explanation:

Energy is directly proportional to frequency and it is given as:

E = hf

where h = Planck's constant

f = frequency

To get frequency, we use the formula of speed:

c = λf

where c = speed of light

λ = wavelength

=> f = c/λ

Therefore, the energy of the photon will be:

E = hc/λ

E = \frac{6.626 * 10^{-34} * 3 * 10^{8}  }{512 * 10^{-9} }

E = 3.88 * 10^{-17} J

The energy of the photon is 3.88 * 10^{-17} J

An object in a fluid experiences a buoyant force from the fluid. If the object is completely immersed, on which does the magnitu
loris [4]

Answer:

Weight of the fluid that the object displaces.

Explanation:

When the fluid is completely immersed in a fluid, it experiences pressure from all the direction. While the object is immersed in the fluid a force acts on it in the opposite direction, i.e., upwards. This force is termed as buoyant force.

Also, as per the Archimedes' Principle, the force experience by the object is the same as the weight of the fluid that gets displaced by the object.

Thus on complete immersion of the object in the fluid, it experiences the force same as the weight of the fluid that gets displaced

According to the ph scale, which substance has the highest hydrogen ion concentration
Damm [24]

Answer:

C) stomach acid

Explanation:

D is wrong due to water have very little to hydrogen ion concentration. tomato juice has acids but it doesn't remove things like stomach acid. oven cleaner does remove some items, but not in a fast fashion like stomach acid. Stomach acid is extremely acidic and will melt about anything that comes in contact. burn is known for doing serious damage if it gets past the stomach lining.

What is the relationship between the electric force and each one of the charges?
Bess [88]

Explanation: Electrostatic force is directly related to the charge of each object. So if the charge of one object is doubled, then the force will become two times greater.

Estimate how much solar energy reaches the earth per year (in Joule).
Alexxandr [17]

Each hour 430 quintillion Joules of energy from the sun hits the Earth.

In a year it is very hard to determine because of the night and different light levels.
