MrRa [10]

Answer:

D. The moon is closer to Earth than the sun.

Explanation:

Tides are formed as a consequence of the differentiation of gravity due to the moon across to the Earth sphere.

Since gravity variate with the distance:

   

F = G\frac{m1\cdot m2}{r^{2}}  (1)                            

Where m1 and m2 are the masses of the two objects that are interacting and r is the distance

For example, see the image below, point A is closer to the moon than point b and at the same time the center of mass of the Earth will feel more attracted to the moon than point B. Therefore, that creates a tidal bulge in point A and point B.

The Sun tidal force contributes to the tidal force of the moon over the earth making high tides higher and low tides lower.  

However, even when the sun is more massive than the moon, it is farther away from the Earth than the moon. So, it is clear by equation 1 that the moon's gravity has a greater effect on Earth's oceans than the sun's gravity.

Which of the following would be a good question that could be scientifically investigated? What is the best advice a parent can
Nesterboy [21]
<span>"Does lack of sunlight affect plant growth?"

This question can be investigated with procedures according to
the Scientific Method, because "lack of sunlight" can be arranged
unambiguously, and "affected plant growth" can be identified
unambiguously.

The other questions involve words or phrases with ambiguous definitions,
that can mean different things to different people, and would be hard to
agree on, like  "</span><span>best advice",  "sound quality",  and  "happiness in life".</span>

A batter hits a pop fly straight up. (a) Is the acceleration of the ball on the way up different from its acceleration on the wa
ExtremeBDS [4]

Answer:

a) No. If air resistance is ignored the acceleration of the ball is the same at each point on its flight.

(b). No. As long as the air resistance is negligible, the acceleration of the ball at the top of its flight different from its acceleration just before it lands.

Explanation:

This constant, similar acceleration is called the acceleration due to gravity and it is the acceleration of a body due to the influence of the pull of gravity alone.

Every object on the surface of the earth regardless of its mass is pulled towards the centre of the earth, especially when in flight. Whether flying upwards, or coming downwards, the pull of attraction towards the surface of the earth is the same!

How does energy travel in a mechanical wave?
VLD [36.1K]

Answer: in a medium

Explanation:

Mechanical waves require medium to transfer energy. The medium particles vibrate about their fixed position to transfer energy.  There is no transport of medium particles.

Example, sound waves are mechanical waves. The sound travels through compression and rarefaction of the medium particles.
