General relativity is a theory of space and time. The theory was published by Albert Einstein in 1915. The central idea of general relativity is that space and time are two aspects of spacetime. Spacetime is curved when there is gravity, matter, energy, and momentum.
The description of the question provided above points out to the famous Big Bang Theory. In addition, this theory is among the most accepted by cosmologists because it fits like a glove to the phenomenon the universe is experiencing right now: it is expanding and distances between celestial bodies are getting farther and farther.
Depends on what the area is. If it’s a rural place, Wood is cheep & easy to build. If there’s a lot of corrosion, strong weather/hurricane, bricks.
Answer:
Joules/second^2=(Newton×meter)/second^2.
Solving for mass: Kg= (second^3/ meter^2).
Answer:
Due to the large mass of the objects, we can not observe wave-like characteristics in daily life.
Explanation:
The wavelength of De-Broglie is given by the relation:

Here, h is Planks constant, m is the mass of electron, v is the velocity.
The Plank’s constant value is very small,so the wavelength which is associated with ordinary object is very small and it is very difficult to observe in our daily life.
In daily life we observe the objects posses the larger mass and much smaller velocity,that is why the wave nature of these large objects is not more common in day to day life.
But for the small objects like neutrons and electrons, the wave behavior of particle is dominating .It is because of the reason that mass of neutron and electron are very small in comparision with the ordinary tennis ball.
