satela [25.4K]

Answer:

C.

Explanation:

If we look at the equation x(final) = v(initial)*t + x(initial), where v(initial in the x dir.) in the same both times, and x(initial) is 0, we can conclude that t is responsible for the change in x(final).

The earth's gravity is pulling on you. Are you pulling on the earth? Explain why or why not.
mel-nik [20]

Answer:

"we both attract each other with the same force but we know that attraction between two bodies depends upon their mass, greater the mass of two bodies is the force of attraction between them"(got this off the internet).

How are Newton’s second and third laws of motion important to your everyday life?
Rasek [7]
Well, first off, Newtons second law of motion <span>deals with the motion of accelerating and decelerating objects.
 W</span>e already know that from everyday life examples such as simply pushing a car that if 2 people push a car on a flat road it will accelerate faster than if one person was pushing it... Therefore, there is a relationship between the size of the force and the acceleration.  
 Now onto the third law of motion. First of all, what is the third law of motion? Well, a force is a push or a pull that acts upon an object as a results of its interaction with another object. Forces result from interactions! According to Newtons third law, whenever one object, and another object interact with each other, they exert forces upon each other. "For every action, there is an equal and opposite reaction."  The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. So, how is this important to everyday life you may ask? 
<span>Well, the action-reaction force pairs are found everywhere in your body.
 For example, right now as I am typing, my tendons are exerting forces on bones, and those bones exert reaction forces on the tendons, as muscles contract, pulling my fingers on the keys. I press on those keys, and they press back on my fingers. See? Since i'm pressing on the keys, the press back on me. Its opposite from each other, as stated in the quite above. "</span><span>For every action, there is an equal and opposite reaction." </span>

PLZ HELP!<br> Which is NOT an example of a longitudinal wave?
LenaWriter [7]

The 1st example is NOT a longitudinal wave

Explanation:

Waves are periodic disturbance of the space that travel carrying energy but not matter.

Depending on their vibration, waves are classified into two types:

  • Transverse waves: in transverse waves, the vibration of the wave occurs in a direction perpendicular to the direction of propagation of the wave. Examples of transverse waves are electromagnetic waves.
  • Longitudinal waves: in longitudinal waves, the vibration of the wave occurs in a direction parallel to the direction of propagation of the wave (back  and forth), creating regions of higher particle density (compressions) and lower particle density (rarefactions). Examples of longitudinal waves are sound waves.

In  this problem we have four options given:

  1. The first picture represents a transverse wave, because the vibration of the robe is up and down, while the wave propagates on the left-right direction
  2. The second picture represents a sound wave, which is a longitudinal wave
  3. The 3rd picture represents a longitudinal wave, since the vibration of the slinky is back and forth along the direction of propagation
  4. The 4th picture also represents a sound wave, which is longitudinal

Therefore, the only wave which is not longitudinal is the one in the 1st picture.
