Most fish fossils are: <u>D. from sharks, eels, and stingrays</u>.

<u>Explanation</u>:

A fossil is a preserved part or trace of a living being in the geological age. Animals, fish, bones and shells are some of the fossils. Fish fossils are the dead fish that are found under the river bed or ocean.

The dead animals in the water bodies are buried under the mud for long period of time. The soft tissues of the animals are decomposed leaving the dry bones.

There are five different types of fossils. They are  

i) Body fossils

ii) Molds and casts

iii) Petrification fossils

iv) Footprints and trackways

v) Coprolites

One of the common fossils is shark tooth. The tooth of the sharks is shed continuously. The fish fossils are found at the bottom of the ocean, lake and pond deposits.

A very light ping-pong ball moving east at a speed of 4 m/s collides with a very heavy stationary bowling ball. The Ping-Pong ba
KengaRu [80]

Answer:

They experience the same magnitude impulse

Explanation:

We have a ping-pong ball colliding with a stationary bowling ball. According to the law of conservation of momentum, we have that the total momentum before and after the collision must be conserved:

where is the initial momentum of the ping-poll ball

is the initial momentum of the bowling ball (which is zero, since the ball is stationary)

is the final momentum of the ping-poll ball

is the final momentum of the bowling ball

We can re-arrange the equation as follows or

which means (1) so the magnitude of the change in momentum of the ping-pong ball is equal to the magnitude of the change in momentum of the bowling ball.

However, we also know that the magnitude of the impulse on an object is equal to the change of momentum of the object:

(2) therefore, (1)+(2) tells us that the ping-pong ball and the bowling ball experiences the same magnitude impulse:

Wittaler [7]

Answer:

the order of arrival is from highest to lowest

star other side of Andromeda> star near side of andromeda> other side of milky way   > center of the milky way> nevulosa orion> Pluto> Sum

Explanation:

The light that comes from stars and galaxies travels in a vacuum so its speed is constant and with a value of c = 3 108 m / s, so time will be directly proportional to the distance to the object

             x = c t

the order of arrival is from highest to lowest

star other side of Andromeda> star near side of andromeda> other side of milky way   > center of the milky way> nevulosa orion> Pluto> Sum

If a string vibrates at the fundamental frequency of 528 Hz and also produces an overtime with a frequency of 1,056 Hz this over
Romashka-Z-Leto [24]
I have a hunch that you're not talking about overtime
OR overtune.  I think you're going for overtone .

For a fundamental frequency of 528 Hz,
1,056 Hz is the second harmonic.
