River water held behind a dam is a form of ________. group of answer choices
WINSTONCH [101]

Potential energy is present in the river water behind a dam.

<h3>How is potential energy defined?</h3>
  • Potential energy is a form of stored energy that is dependent on the relationship between different system components.
  • When a spring is compressed or stretched, its potential energy increases.
  • If a steel ball is raised above the ground as opposed to falling to the ground, it has more potential energy.
  • The object's mass, its mass in relation to some reference points, and the gravitational field it is in all affect the potential energy of the object.
  • Joule is the SI unit of potential energy as a result (J)
  • As weight and height increase, gravitational potential energy rises.

calculate the time (in years) it would take to send a message to the Galactic Capitol located at the center of our Milky Way gal
Alinara [238K]

Answer:

The total time is \bf{52850~Yr}.

Explanation:

Given:

The distance between Galactic Capitol and Earth is, d = 2.5 \times 10^{20}~m

The speed of light is, c = 3 \times 10^{8}~m/s

The time taken by the message to reach and come back to Earth is given by

t &=& \dfrac{2d}{c}\\~~&=& \dfrac{2(2.5 \times 10^{20}~m)}{3 \times 10^{8}~m/s}\\~~&=& 1.6 \times 10^{12}~s\\~~&=& \dfrac{1.6 \times 10^{12}~s}{(86400 \times 365)~s}~Yr\\~~&\approx& 52849~Yr

In addition they take 1 year to decide to reply.

Thus, the total time is 25850~Yr.

All waves on the electromagnetic spectrum travel at the same speed in a vacuum. The speed of these waves in a vacuum is 3x10 8 m
Alexandra [31]
As you said, the speed is constant in a vacuum, so the speed does not change, The frequency, on the other hand, decreases by half. The wavelength, λ (lambda), the frequency, v, and the speed of light, c, are related by the equation λν = c. We can see that frequency and wavelength are inversely proportional, so an increase in wavelength has a corresponding decrease in frequency.

Light can be made to have a higher intensity by raising its
e-lub [12.9K]

Answer:

Frequency

Explanation:

The intensity of light is increased by increasing the number of photon per second, and the number of photon per second is referred to as frequency. A photon the smallest unit of light. If the frequency is increased, the number of photons per second increases hence an increase in intensity.
