The complete question is

What modifications did kepler make to copernicus’s model? check all that apply. planetary orbits are elliptical. planets closer to the sun move faster. planets spin in an epicycle while orbiting earth. venus has phases due to its orbiting of the sun. earth’s rotation causes the rising and setting of the sun.

Answer:

Planetary orbits are elliptical.

Planets closer to the Sun move faster.

Explanation:

The first option is based on the first law that states that the planets orbit the sun in ellipses, with the sun at one focus of the ellipse.

The second option is based on the third law that states that the square of the time of revolution about the sun is directly proportional to the cube of the mean radius of orbit of the planet.

How are the climates of coastal regions affected by the specific heat capacity of water?
Katen [24]

Answer:

The specific heat capacity can be defined as the amount of heat required to raise the temperature of 1 unit of mass by 1 unit temperature. The specific heat capacity of water is 4.186 joule/gram °C which is higher than common substances. The land has lower specific heat capacity. Thus, the land gets hot quickly than water.

This results in warming up air near the land which creates a difference in pressure across the coastal region. Sea breeze blows from sea towards landmass. Opposite happens at night, when water is still warm and land gets cooled down quickly. Then land breeze blows  from landmass towards the sea. This breeze maintains a moderate temperature and windy and humid weather in the coastal regions.

Figure 3 shows a bicycle of mass 15 kg resting in a vertical position, with the front and back
Vinil7 [7]

Explanation:

There are three forces on the bicycle:

Reaction force Rp pushing up at P,

Reaction force Rq pushing up at Q,

Weight force mg pulling down at O.

There are four equations you can write: sum of the forces in the y direction, sum of the moments at P, sum of the moments at Q, and sum of the moments at O.

Sum of the forces in the y direction:

Rp + Rq − (15)(9.8) = 0

Rp + Rq − 147 = 0

Sum of the moments at P:

(15)(9.8)(0.30) − Rq(1) = 0

44.1 − Rq = 0

Sum of the moments at Q:

Rp(1) − (15)(9.8)(0.70) = 0

Rp − 102.9 = 0

Sum of the moments at O:

Rp(0.30) − Rq(0.70) = 0

0.3 Rp − 0.7 Rq = 0

Any combination of these equations will work.

Which of the following is true of microscopic particles? They can be localized or not localized in space They can explain the ph
Alona [7]

Answer:

true about microscopic particle is that they can explain the phenomena of diffraction and interference.

Explanation

the first thing mentioned in question particles are localized in space according to classical physics particle can be well localized in space because its momentum and position can be determine simultaneously .second their properties can be measured and they can act like wave particle by particle build up a wave. so all of they things mention above only thing true about particles is that they describe the phenomena of diffraction and interference.
