Which is a reason democracy failed following most Latin American revolutions?
Which is a reason democracy failed following most Latin American revolutions?
Educated Creoles opposed the ideas of the Enlightenment. The people of Latin America had very little experience with self-government. Military dictators worked well together to prevent democracy. Latin American revolutionary leaders had little outside inspiration for their revolutions.
What is the relationship between the force of gravity and the mass of the objects involved?
Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.
What is the relationship between mass and distance?
Newton’s law of universal gravitation states that every point mass in the universe attracts every other point mass with a force that is directly proportional to the product of their masses, and inversely proportional to the square of the distance between them.
What do you mean by dielectric Polarisation?
Dielectric polarization is the term given to describe the behavior of a material when an external electric field is applied on it. The charges in the material will have a response to the electric field caused by the plates.
What is meant by Polarisation?
Polarization (also polarisation) is a property applying to transverse waves that specifies the geometrical orientation of the oscillations. In linear polarization, the fields oscillate in a single direction. In circular or elliptical polarization, the fields rotate at a constant rate in a plane as the wave travels.
What are the two types of dielectrics?
There are two types of dielectrics – Non-polar dielectric and polar dielectric.
Which of the following is the slowest Polarisation method?
8. Which of the following is the slowest polarisation method? Explanation: Space charge polarisation is very slow because in this case, the ions have to diffuse over several interatomic distances. Also, this process occurs at a very low frequency.
Which type of polarization is temperature dependent?
Identify which type of polarisation depends on temperature. Explanation: The electronic, ionic and interfacial polarisation depends on the atoms which are independent with respect to temperature. Only the orientational polarisation is dependent on the temperature and is inversely proportional to it.
How does ionic Polarisation occur?
Ionic Polarization occurs due to relative displacements between positive and negative ions in an ionic crystal. If a crystal or molecule consists of atoms of more than one kind, the distribution of charges around an atom in the crystal or molecule leans to positive or negative.
Which type of the following substance is dielectric?
Mica is a dielectric.
How did Isaac Newton discover gravity?
The legend is that Newton discovered Gravity when he saw a falling apple while thinking about the forces of nature. Whatever really happened, Newton realized that some force must be acting on falling objects like apples because otherwise they would not start moving from rest.
Which best explains the role of nationalism in Europe following the Congress of Vienna?
Your correct answer to this question would be “Resisting Napoleon’s armies prompted many to resist the return of traditional monarchies.” Nationalism in the states led to aggressive posturing about where the borders would be. Hope this helps.
Why was the law of gravitation important?
Newton’s law of gravitation is simple equation, but devastatingly effective: plug in the numbers and you can predict the positions of all the planets, moons and comets you might ever want to watch, anywhere in the solar system and beyond. And it allowed us to add to those celestial bodies too, heralding the space age.
What is universal law of gravitation and its importance?
Importance of The Universal Law of Gravitation It binds us to the earth. It is responsible for the motion of the moon around the earth. It is responsible for the motion of planets around the Sun. Gravitational force of moon causes tides in seas on earth.
What is the basic idea of the law of universal gravitation?
Newton’s law of universal gravitation is usually stated as that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
What is G called?
The gravitational constant G is a key quantity in Newton’s law of universal gravitation….Gravitational constant.
| Values of G | Units |
|---|---|
| 4.×10−3 | pc⋅M⊙–1⋅(km/s)2 |
Who discovered the law of universal gravitation?
Sir Isaac Newton
What did Einstein mean by time is relative?
A Matter of Time. In the Special Theory of Relativity, Einstein determined that time is relative–in other words, the rate at which time passes depends on your frame of reference.
What did Einstein’s theory of relativity prove?
Albert Einstein, in his theory of special relativity, determined that the laws of physics are the same for all non-accelerating observers, and he showed that the speed of light within a vacuum is the same no matter the speed at which an observer travels.
What does E mc2 mean in simple terms?
Energy equals mass times
What is the difference between the two theories of relativity?
The “General Theory of Relativity’ is related to gravity. It describes gravitational force as continuous non-spatial whole of space and time. The difference between the two theories is that the theory of general relativity throws light on the force of gravity with respect to curving four-dimensional space-time.
Why is it called theory of relativity?
Einstein’s theory gets its name because it describes how measurements of space and time differ for observers moving relative to one another. 3. The theory gets its name from the relativity of motion, but the fact that motion is relative had already been known for centuries.
What is the theory of relativity in simple words?
What is general relativity? Essentially, it’s a theory of gravity. The basic idea is that instead of being an invisible force that attracts objects to one another, gravity is a curving or warping of space. The more massive an object, the more it warps the space around it.
Why is C Squared?
Energy is measured in units of mass times velocity squared. Hence, the factor between mass and energy has to be (m^2 / s^2) which is some velocity squared. And the only fundamental constant we have that is a velocity is the speed of light c. That’s why it has to be c^2.
Why is C used in E mc2?
Now we’re getting to the c² part of the equation, which serves the same purpose as the star-on and star-off machines in “The Sneetches.” The c stands for the speed of light, a universal constant, so the whole equation breaks down to this: Energy is equal to matter multiplied by the speed of light squared.
How do you use e mc2?
Enter E=mc2. This seemingly simple algebraic formula represents the correlation of energy to matter (energy equivalence of any given amount of mass). Many have heard of it, but not very many understand what it implies. Many people are unaware of just how much energy is contained within matter.
How do you solve E mc2 problems?
The speed of light is approximately, m per second; (m/s)^2 equals meters squared per second squared, or 9 x 10^16 m^2/s^2. Multiply the result by the mass of the object in kilograms. If the mass is 0.1 kg, for example, (0.1 kg)(9 x 10^16 m^2/s^2) = 9 x 10^15 kgm^2/s^2.
Is E mc2 always true?
On paper at least, he showed that while E=mc2 always holds true for inertial mass, it doesn’t always for gravitational mass. “What this probably means is that gravitational mass is not the same as inertial,” he said. According to Einstein, gravitation is a result of a curvature in space itself.
