Oksanka [162]3 years ago
6 0

Answer:

d. Every second, the truck’s velocity increases by 3 km/h to the south.

Explanation:

Acelleration can be defined as change of velocity over change of time.

That's why if we say:  "A truck accelerates 3 km/h/s south."

We are saying that the acceleration of the truck variate 3Km/h wich is  velocity of the truck, and it variates every second and also its direction is south.

True or false gravitational pull decreases with an increase of distance between two objects​
ohaa [14]

Answer:

true! : )

(i underlined the place where the answer is the other information is just as important but if you do not want to read it you do not have to)

Explanation:

Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases. the greater the mass, the greater the gravitational pull. <u>gravitational pull decreases with an increase in the distance between two objects.</u> Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.

On your drive home from school, you travel 1200 m in 80 s, then 400 min 20 s.
Mama L [17]

Average speed = Total distance/total time taken

=  \frac{1200 + 400}{80 + 20}

=  \frac{1600}{100}

=  \frac{16}{1}

= 16 \: ms {}^{ - 1}
