If you see a spacecraft moving past you at 90% of the speed of light, and if you are able to watch a clock on the spacecraft, then according to special relativity you will see the clock
Answers
Answer:
Measures a slower course of time
Explanation:
According to the theory of relativity, there is a difference in the time measured by two observers, due to a relative speed difference between them. In other words, you observe that a clock that moves with respect to you will measure a slower course of time than a clock that is at rest in your frame of reference.

Answers
Answer;
C) decreases; increases
Explanation;
- As we move through the visible spectrum, red to violet (right to left in the image), the wavelength decreases and the frequency increases.
- Electromagnetic spectrum comprises of electromagnetic waves arranged in the order of increasing or decreasing frequency and wavelength.
- These electromagnetic waves includes; radio waves, microwaves, infrared, visible light, ultraviolet, x-rays and gamma rays.
- In electromagnetic spectrum as you move from left to right, that is from the radio waves towards the gamma rays, the wavelength decreases as the frequency increases; while from gamma rays towards the radio waves the wavelength increases while the frequency decreases.

Answer:
C. work function
Explanation:
In the photoelectric effect, the energy of the incident photon is used in part to extract the electron from the metal (and this energy is called work function) and the rest is converted into kinetic energy of the electron. In formula:
where
hf is the energy of the incident photon, which is the product between h (the Planck constant) and f (the photon's frequency)
is the work function
K is the kinetic energy of the photoelectron as it leaves the material

Bode's Law, also known as Titius-Bode law, provides a numerical pattern that predicts the position of most planets in our Solar System, including Jupiter. It, however, fails to accurately predict the location of Uranus and Neptune. The fundamental principles of planetary motion were established by Kepler's laws and later consolidated by Newton in his Universal Law of Gravitation.
Explanation:
This question pertains to Bode's Law, a rule of planetary distances at times referred to as the Titius-Bode Law. The rule indicates a pattern of increasing distances of the planets from the sun, which interestingly correlates to the position of most planets in our Solar System, including Jupiter. However, exceptions, particularly Uranus and Neptune, don't fit precisely into this pattern.
The origins of planetary motions can be traced back to the work of scientists like Herr Tycho Brahe, Johannes Kepler, and Sir Isaac Newton. Kepler's work in particular developed three fundamental laws of planetary motion using Brahe's meticulously collected data. These laws describe the behavior of planets in their orbits and together provide the foundation of the Universal Law of Gravitation as later synthesized by Newton.
