According to newton's third law: every action has an equal and opposite reaction, so yes the ground does move backwards. You have 4 forces acting on you at any given time: pushing force, friction force, gravity, and normal force. you push against something to propel forward, you have to overcome gravity and friction, and normal force keeps things upright to prevent them from falling into each other.
<span>If everything is motionless at every instant, and time is entirely composed of instants, then motion is impossible, so it must be an illusion.

if you really want things to get confusing you can read up on zeno's dichotomy paradox stating that there is infinate amount of times you can divide something such as a distance traveled over time and you will stil
<h3><u>Answer;</u></h3>
travel through solids
P waves and S waves are alike in that they<u> both travel through solids</u>.
<h3><u>Explanation;</u></h3>
- <em><u>P-waves and S-waves are types of seismic waves.</u></em> These waves are produced during an earthquake, that transmit energy released around the earth.
- <u><em>P-waves travel the fastest and also travel through solids, liquids and gases. </em></u>They are push and pull waves and thus they cause rock particles to move back and forth.
- <u><em>S-wave son the other hand arrive at a given point after the p-waves. They do not travel as fast as P-waves. They travel through solids but not in liquids and gases.</em></u> S -waves cause the rocks to move side to side.
The answer is A. drops! Suppose a drinking straw is in a glass of water. Someone blows air across the top of the straw. The water level in the straw will be drops.
Hope it helped!

Energy used by heater is 8.21 x 10⁶ J</h2>
Explanation:
Energy = Power x Time
Power = Voltage x Current
Voltage = 120 V
Current = 9.5 A
Power = Voltage x Current
Power = 120 x 9.5 = 1140 W
Time = 2 hours = 2 x 60 x 60 = 7200 s
Energy = Power x Time
Energy = 1140 x 7200
Energy = 8208000 J
Energy used by heater is 8.21 x 10⁶ J
