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.
The main morphological types of galaxies are elliptical, spiral, and irregular.
Based on their morphology , galaxies have been classified into 3 types namely elliptical, spiral, and irregular.
These galaxies have various sizes and shapes ranging from dwarf galaxies to giant galaxies.
Elliptical Galaxy:
- The shape of it is generally circular
- These are the largest among all the types of galaxies because according to astronomers, it is formed by the merger of other small galaxies.
- Their rotational pattern is symmetric.
Spiral Galaxy:
- A spiral galaxy consists of a bright nucleus surrounded by a thin outer disk forming a spiral shape.
- This type of galaxy is the most common in our universe.
- It is divided into three classes: Spiral a, Spiral b, and Spiral c.
- Their rotational pattern has circular symmetry.
Irregular Galaxy:
- These types of galaxies have no central nucleus and irregular arms which are bluish.
- They don’t have any rotational symmetry.

Voltage = joules/coulomb
1 coulomb = 6.25 x 10^18 electrons
8.5 x 10^18 electrons = 1.36 coulombs
136 joules / 1.36 coulombs = 100 volts

The statement regarding the ball is false. Any object that's not hanging from something
or resting on something is accelerating downward on account of gravity. No matter what
direction you throw the ball, or how hard, its acceleration is 9.8 meters per second^2
directed downward, from the instant it leaves your hand until it hits the ground.
Answer:
Pumping a well lowers the water level around the well to form a cone of depression in the water table. If the cone of depression extends to other nearby wells, the water level in those wells will be lowered. The cone develops in both shallow water-table and deeper confined-aquifer systems.
