What number does Ameena declare as the number Sara had thought of in the game?
15
What does Appu ask Balu to do in the game?
Think of a number, multiply it by 10, and subtract 20 from the product
What number does Appu immediately tell as the number thought by Balu in the game?
7
Who first proposed the concept of gravitational waves?
Oliver Heaviside
In what year were gravitational waves predicted by Albert Einstein?
1916
How do gravitational waves transport energy?
Through gravitational radiation
Why does Newton's law of universal gravitation not provide for the existence of gravitational waves?
Because it assumes physical interactions propagate instantaneously
At what speed do gravitational waves propagate?
At the speed of light
Study Notes
Game Scenario
- Appu, Sarita, and Ameena have constructed a guessing game.
- In the game, Ameena asks Sara to think of a number.
- Ameena declares that the number Sara had thought of is 7.
- Appu asks Balu to think of a number.
- Appu immediately tells the number thought by Balu, which is 27.
Gravitational Waves
- The concept of gravitational waves was first proposed by Henri Poincaré.
- Albert Einstein predicted the existence of gravitational waves in 1915.
- Gravitational waves transport energy through space.
- Newton's law of universal gravitation does not provide for the existence of gravitational waves because it does not account for the dynamic nature of gravity.
- Gravitational waves propagate at the speed of light.
