According to kepler’s second law, where in a planet’s orbit would it be moving fastest? where would it be moving slowest?

Answer and Explanation :

According to Kepler's second law the speed of the planet depends on the distance between the Sun and the planet the speed of planet is the fastest when the planet is closer to the Sun and speed of the planet is the slowest when it is farthest from the Sun. This the Kepler's law , It determines how the speed of the object varies according to orbit.  

cell differentiation  is how generic embryonic  cells  become specialized  cells. this occurs  through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a  cell  functions.

explanation:

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
