Answer: The multiplication factor is 72.136 cm. This will give you the unit conversion when multiplied with 28.4 inch
Explanation:
1 inch = 2.54 cm
28.4 inches = x cm
Xcm= (28.4 inches × 2.54cm)/1 inch
X= 72.136
The total distance traveled by the body is the sum of the distance it traveled for the first five seconds which is 10 m and that of the next five seconds which is 30 meters. Thus, the total distance traveled is 40 m. Dividing this by the time, will give the average speed. The average speed is therefore, 4 m/s. The answer is letter C.

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.
