Answer:
Explanation:
Acceleration of gravity on the surface of
Neptune is given
g' = G M/R^2,
where M is the planet's mass.
M g' will be the apparent weight registed at the poles.
G is the universal constant of gravity
The "apparent weight" at the equator will be
reduced from M g' by the centripetal force M
R w^2, where w is the rotational angular
velocity in radians/s), which you can deduce
from the 16 hour length of a day.
Answer:
The flow of energy from falling water to the steam is;
a) Mechanical → Mechanical → Electrical → Thermal → Thermal
Explanation:
1) Mechanical → Mechanical
The water in the pipe before it falls possesses potential energy which it converts into kinetic energy as it falls from height
2) Mechanical → Mechanical
The water falling from the pipe stream unto the turbine wheel transfers its kinetic (mechanical) energy due to its motion on to the turbine wheel to give the wheel rotational motion
3) Mechanical → Electrical
The kinetic (mechanical) energy from the rotating turbine wheel is converted into electrical energy in the electrical generator which transported through the electrical circuit
4) Electrical → Thermal
The electrical energy from the electric current is then converted into thermal energy as the current passes through the resistors in the heating filament
5) Thermal → Thermal
The heated filament transfers thermal energy to the the water in the beaker by conduction which raises the temperature of the water such that as the water acquires more thermal energy it turns into steam
Therefore, we have the flow of energy from the falling water to steam as follows;
1) Mechanical 2) Mechanical 3) Electrical 4) Thermal 5) Thermal
1.What types of geological events or changes occur at divergent plate boundaries?
Volcanoes and minor earthquakes occur at divergent plate boundaries.
2. What types of geological events or changes occur at convergent plate boundaries? Volcanoes, earthquakes and fold mountains occur at convergent plate boundaries.
3. What types of geological events or changes occur at transform plate boundaries? Earthquakes and fold mountains occur at transform plate boundaries.
4. Explain how these geological processes and interactions have changed Earth's surface through the years. Magma from volcanoes is filled with nutrients that makes land fertile. Some earthquakes make the ground shake so violently that it destroys entire landscapes and environments. Earthquakes can also cause landslides and tsunamis, which destroy whole villages, change geology and ruin natural habitats of many living creatures. W<span>hen an earthquake happens in the middle of the ocean, it can create waves that are so large that they destroy coastlines, cities, and forests hundreds of miles away.</span>
<u>Complete Question:</u>
Which of the following electromagnetic waves carries the highest energy, and are most damaging to human?
A. Gamma Rays
B. Microwave
C. Radio-wave
D. Alpha Rays
<u>Correct Option:</u>
Gamma Rays carries the highest energy, and are most damaging to human.
<u>Option: A</u>
<u>Explanation:</u>
The waves of light and other forms of energy that radiate or travel from where they are originated is understood as electromagnetic radiation, and collectively represent electromagnetic spectrum. The gamma rays are dangerous sources of radiation with high energy. Its standard size is 0.000001 nm i.e. size of atomic nucleus diameter. It results from the degradation of atomic nuclei by radioactive means. It is made up of the smallest electromagnetic wavelength, and thus provides the highest photon energy.
The belief that the stars determine our fate is considered to be pseudoscience .
- Large celestial bodies called stars are mostly made of hydrogen and helium, and in their cores, churning nuclear forges produce light and heat. Except for our sun, all of the other stars in the sky that we can see are light-years from the our planet i.e. earth.
- Celestial bodies, also referred to as heavenly bodies, are celestial objects in space, including the sun, moon, planets, and stars. They are a component of the vast universe that we exist in and are normally fairly far away from us.
Pseudoscience, which is defined as an activity that purports to be scientific but is actually not, is defined as seems science. Science does not engage in extraterrestrial affairs it simply studies the natural world. Science cannot provide an answer to morality, immorality, or questions of meaning or purpose, but it does require ethical behavior. In other hand astronomy is regarded as pseudoscience since no link between the locations of the stars and human behavior can be demonstrated using evidence from science.
