First blank: inertiaSecond blank: rest; Third blank: rest; Fourth blank: velocity; Fifth blank: speed; Sixth blank: direction; Seventh blank: unbalanced

Explanation:

Your question about the first law is:

Newton's first LAW OF 1

Newton's first law says that an object is NOT MOVING, or is at 2

will stay at 3 . AND an object that is MOVING will keep moving with constant 4 , which means at the same 5

and in the same 6 . UNLESS an 7 force acts on that object.

Solution

1. First blank: inertia

Newton stated 3 forces of motion: first law is called the law of inertia , because it deals with the fact that if none force acts on an object then the object will keep the same state that it has.

2. Second blank: rest; third blank: rest

The state of no motion is defined as rest, thus second and third blanks correspond to rest

3. Fourth blank: velocity

Not just the speed is constant, the velocity, which is a vector, is constant. Thus the object will continue moving in straight and with the same speed.

4. Fith blank: speed, sixth blank: direction

To be more emphatic, the next two blanks explains that constant velocity is the involves both concepts: constant speed and constant direction.

5. Seventh blank: unbalanced

The concept of unbalanced force is related to net force. In order to a body change its state of rest or constant velocity the net force acting on it must not be zero. If two or more forces act on an object and they are balanced (net force equal to zero) the body will not change its state and will continue at rest or with constant velocity.

The filled in text would be:

Newton's first LAW OF INERTIA

Newton's first law says that an object is NOT MOVING, or is at REST

will stay at REST . AND an object that is MOVING will keep moving with constant VELOCITY , which means at the same SPEED and in the same DIRECTION . UNLESS an UNBALANCED force acts on that object.

Look at the spectrums of a star moving towards earth and a motionless star. which of these is a correct inference that can be draw from the observation of the two spectrums? (2 points) the spectrum of a motionless star is difficult to be viewed separately using oridinary telescopes. the spectrum of a motionless star is identical to the spectrum of a star which moves towards earth. the spectrum of a star shifts towards the red region when the star moves towards earth. the spectrum of a star shifts towards the blue region when the star moves towards earth.

Scientists often have to deal with numbers that are either very large or very small. for example, the radius of the sun is approximately 696,000 kilometers, while bacterial cells are as small as 1.9 × 10-4 millimeters. express each number in an alternate form.
