Atoy car is placed at 0 on a number line. it moves 9 cm to the left, then 4 cm to the right, and then 6 cm to the left. the total distance the toy car traveled is

Total distance, d = 19 cm

Explanation:

It is given that, A toy car is placed at 0 on a number line. It moves 9 cm to the left, then 4 cm to the right, and then 6 cm to the left.

We know that the distance travelled by a toy car is equal to the sum of total path covered. The displacement is equal to the shortest path covered by an object.

So, the total distance is given by,

d = 19 cm

Hence, this is the required solution.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
