Answer:
The new planet has more gravity
Explanation:
gravity force = G m1 m2 / r^2
decresing r or increasing the planet mass will increase the force
Average speed = total distance / total time
= (81 + 88) / (2 + 2)
= 169/4
= 42.25 kilometers/hour

Answer:
Distance = 30 m
Explanation:
Since the position of the bus is at zero, and distance is a scalar quantity. That is, we are only concerned about the magnitude
If Angela ran to the bus and back to where she started, the distance travelled will be:
Distance = 15 + 15 = 30 m
But her displacement will be:
Displacement = 15 - 15 = 0.
