According to the law of universal gravitation, any two objects are attracted to each other. the strength of the gravitational force depends on the masses of the objects and their distance from each other. many stars have planets around them. if there were no gravity attracting a planet to its star, the planet's motion would carry it away from the star. however, when this motion is balanced by the gravitational attraction to the star, the planet orbits the star. two solar systems each have a planet the same distance from the star. the planets have the same mass, but planet a orbits a more massive star than planet b. which of the following statements is true about the planets? a. planet b is more attracted to its star than planet a. b. planet a has a longer year than planet b. c. planet a orbits its star faster than planet b. d. planet b will keep orbiting its star longer than planet a.

C. Planet A orbits its star faster than Planet B.

Explanation:

The force of gravitational attraction depends on the masses of the bodies involved. The greater the mass, the greater the force of attraction between them.

Based on this, we can say that the gravitational force between planet A and the star it orbits is stronger than planet B and its star. That's because the star of planet A has a greater mass than the star of planet B.

Since the gravitational force between planet A and its star is greater than the gravitational force between planet B and its star, we can say that planet A will orbit its star faster than planet B will orbit its star.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
