1 Gravitational waves A Are how pulsars pulse B Carry materi

1) Gravitational waves A. Are how pulsars pulse. B. Carry material into black holes. C. Are traveling distortions of space and time. D. Do not carry energy.

2) An isolated black hole will A. Eventually suck in all of the Universe. B. Implode due to its own gravity. C. Not change in any way. D. Slowly evaporate away through the emission of Hawking radiation.

3) The surface temperature of a white dwarf is higher than the surface temperature of the Sun. True or False

4) A gravitational wave can carry energy away from two very dense objects if they are orbiting each other or collide. True or False

Solution

1)

Gravitational waves are \'ripples\' in the fabric of space-time caused by some of the most violent and energetic processes in the Universe.

the correct option is C. Are traveling distortions of space and time.

2)

A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing—including particles and electromagnetic radiation such as light—can escape from inside it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.

the correct option is C. Not change in any way.

3)

The surface temperature of a white dwarf is higher than the surface temperature of the Sun. TRUE

4)
A gravitational wave can carry energy away from two very dense objects if they are orbiting each other or collide. True
