in its image after reflection is -

3. The energy stored in the nucleus of an atom -

5. When two light nuclei combined to form a heavy nucleus-

Give answers in word​

Answer 1

Answer:

1)answer:For example, for visible light, the refractive index of glass is typically around 1.5, meaning that light in glass travels at c / 1.5 ≈ 200000 km/s (124000 mi/s); the refractive index of air for visible light is about 1.0003, so the speed of light in air is about 90 km/s (56 mi/s) slower than c.

Metres per second: 299792458

One light year: 1.0 year

Miles per second: 186000

Parsecs per year: 0.307

2) answer:The interchange of the left and right sides in the image of the object in a plane mirror is known as lateral inversion.

3) answer:Nuclear energy is energy stored in the nucleus of an atom; it is the energy that holds the nucleus together. The energy can be released when the nuclei are combined or split apart.

4) answer:A musical instrument is simply a producer of controlled sound. All instruments have something that vibrates: a string on a guitar, for instance; a drumhead; a reed in a clarinet or saxophone. In a trumpet, the player's lips vibrate to create the sound.

5)answer:In fusion reactions, two light atomic nuclei fuse together to form a heavier nucleus and release a large amount of energy. The basic concept behind any fusion reaction is to bring two light nuclei close enough so the residual strong force (nuclear force) in their nuclei will pull them together.

Answer 2

Answer:

1.90 km/s (56 mi/s

2.lateral inversion

3.Nuclear energy

4.Three things vibrate when sound is created:

the source object.

the molecules in the air (or another medium e.g. water)

the eardrum.

5.In fusion reactions, two light atomic nuclei fuse together to form a heavier nucleus and release a large amount of energy. The basic concept behind any fusion reaction is to bring two light nuclei close enough so the residual strong force (nuclear force) in their nuclei will pull them together.
