Given:
An empty bottle moves up and down as water waves pass beneath it.
The bottle does not move toward the shore with the waves.
Required: To choose the correct option.
Explanation:
The waves are disturbances in the medium which transfer their energy to the surrounding particles in the medium without changing their place.
Final Answer: Waves transmit energy but not matter as they progress through a medium(Option C).
Which of the following objects would be moved more easily by an applied force
To find:
The reason for the regular interval of 12 hours between the tides.
Explanation:
The earth rotates in the same direction as the revolution of the moon around the earth. Thus, it takes the earth an extra fifty minutes every day to catch up to the moon. That is the earth catches up to the moon every 24 hours and 50 minutes.
Thus there will be two high and two low tides in a day. Thus there will be 12 hours of interval between two high tides. In other words, the side of the earth that is far from the moon will be near the moon after 12 hours.
Final answer:
Thus the correct answer is option B.
Explain how projectile motion works in real life like basketball
We will have that projectile motion works in an almost exact way as the theory tells us; the difference lies in the fact that the theories are modeled for a perfect system, but real life is not perfect and there are incredibly small variables that affect the movement of objects.
Now, in the case of basketball for example an object will have a mass, this object will be thrown with an initial velocity, acceleration and angle; now all of this affects the parabolic motion of the object. When in movement there are other forces the object has already been subjected to, like gravity that "pulls" on the object every moment, but when thrown then starts to bring the object to the ground.
The general form of the projectile movement is the one presented in the graph; but in real life there are factors that change the behavior slightly, such as friction with the medium, pressure, temperature, inertia of the object, another external forces, and so on.
