Acceleration  =  (change in speed) / (time for the change)

Change in speed = (speed at the end) - (speed at the beginning)

                            =         (3 m/s)           -       (8 m/s)

                            =                      -5 m/s .

Time for the change  =  1 minuet = 2 sonatas = 60 seconds

Acceleration  =  (-5 m/s) / (60 seconds)

                      =     - 1/12  m/s²

                      =      0.0833  m/s²

                      =        8-1/3  cm/s²

The inner planets are relatively small bodies composed mostly of rock and metals. Why did they develop this way instead of becom
sleet_krkn [62]

The temperature of the early solar system explains why the inner planets are rocky and the outer ones are gaseous. As the gases coalesced to form a protosun, the temperature in the solar system rose. In the inner solar system temperatures were as high as 2000 K, while in the outer solar system it was as cool as 50 K. In the inner solar system, only substances with very high melting points would have remained solid. All the rest would have vaoprized. So the inner solar system objects are made of iron, silicon, magnesium, sulfer, aluminum, calcium and nickel. Many of these were present in compounds with oxygen. There were relatively few elements of any other kind in a solid state to form the inner planets. The inner planets are much smaller than the outer planets and because of this have relatively low gravity and were not able to attract large amounts of gas to their atmospheres. In the outer regions of the solar system where it was cooler, other elements like water and methane did not vaporize and were able to form the giant planets. These planets were more massive than the inner planets and were able to attract large amounts of hydrogen and helium, which is why they are composed mainly of hydrogen and helium, the most abundant elements in the solar system, and in the universe

A 3 kilogram block is sliding across the ground at a velocity of 8 meters per second. What is the momentum of the block?
oksano4ka [1.4K]

Answer:

24 kgm/s

Explanation:

Momentum (p) = mass x velocity

Mass = 3kg , velocity 8m/s

momentum (p) = 3kg x 8m/s

= 24kgm/s

Dez pours water (n 1.333) into a container made of crown glass (n 1.52). The light ray in ner made of crown glass (n = 1.52). Th
siniylev [52]

Answer:

The angle of the corresponding refracted ray is 34.84°

Explanation:

Given that,

Refractive index of water n= 1.33

Refractive index of glass n= 1.52

Incident angle = 30.0°

We need to calculate the refracted angle

Using formula of Snell's law

n_{i}\sin i=n_{r}\sin r

Put the value into the formula

\sin r=\dfrac{n_{i}\sin i}{n_{r}}

\sin r=\dfrac{1.52\times\sin30}{1.33}

\sin r=0.5714

r=sin^{-1}0.5714

r = 34.84^{\circ}

Hence, The angle of the corresponding refracted ray is 34.84°

Answer:

Answer: Anthony will be warmer after the game.

Explanation:

Anthony and Maelynn are watching a football game outside on a sunny day. Anthony is wearing a black shirt and Maelynn is wearing a white shirt. Anthony will be warmer after the game. The black color is a good absorber of radiation and a bad reflector.
