Answer:
6. a. friction between a tire and the road
7. c. energy of motion
8. c. the force with which a moving vehicle hits another object
Explanation:
6. As a car moves along the road, the tires push back against the ground. As tires push back against the ground, the road exerts and opposing force to the motion of the tires. This opposing force is the friction between the tires and the road. <u>This opposing force between the tires and the rad is called traction.</u>
So, the answer is a
7. As an object moves, it has energy. <u>This energy due to its motion is called kinetic energy.</u>
So, the answer is c
8. When a moving vehicle hits another object, it exerts a force on the object. The process of the vehicle hitting the other object is called impact and the<u> force exerted on the object is called the force of impact. </u>
So, the answer is c.

Answer:
speed of slower car is 71 km/h
Explanation:
The distance between two cars is given as

time taken by two cars to meet is given as

now the relative speed of two cars is given as


also it is given that the difference of speed of two cars is

now from above two equations we have


The answer would be energy, because all wave emitters give off at least one type of energy....
Answer:
We obtain the average velocity instead of the instantaneus velocity.
Explanation:
The problem with calculating speed in this way is that an average speed is being calculated and not an instantaneous speed at a given point.

To calculate the instantaneous speed, a very small space interval must be measured at a given time.
