Still really need help with these three questions!!

Physics
1 answer:
Slav-nsk [51]3 years ago
7 0

Explanation:

2.  No, not always.  Normal force is equal to force of gravity only when there's no acceleration in the vertical direction.

For example, when you stand in an elevator that's not moving, or moving at constant speed, then the normal force equals your weight.  But when the elevator accelerates upward, the normal force increases (making you feel heavier).  And when the elevator slows down, the normal force decreases (making you feel lighter).

3.  Yes, it is possible for an object to be moving eastward and experience a net force westward.  An example is a car applying the brakes.

4.  Friction force allows you to walk.  When you push against the floor, the floor's friction pushes back, as Newton's third law says.

If you try to walk on a slippery surface like ice, you won't be able to push against the ice, and the ice won't push back.

In addition to light and chlorophyll photosynthesis requires
labwork [276]

Answer:

Water (H₂O) and Carbon dioxide (CO₂)

Explanation:

Photosynthesis usually refers to the process by which the green plants can synthesize their own food in the presence of sunlight, water, carbon dioxide, and light. This process helps in the conversion of light energy into chemical energy.

In addition to the sunlight and chlorophyll, the process of photosynthesis requires water as well as carbon dioxide. The plants are comprised of green pigments on their leaves that are commonly known as chlorophyll. These pigments absorb the water molecules and carbon dioxide gas that helps in synthesizing their food.

The equation for the process of photosynthesis is given below:

6CO₂ + 6H₂0 + (energy) → C₆H₁₂O₆ + 6O₂

Syncopation is when we "shift" the beat off of the strong or down beat.
BabaBlast [244]

Given what we know, the statement in this question can be considered as true, since Syncopation does in fact shift the beat off of regular rhythms.

<h3>What is Syncopation?</h3>
  • This is when regular beats are offset in order to disrupt the melody.
  • This is done purposefully.
  • It causes the listener a need to continue in order to hear the beat return to normal.

Therefore, given that Syncopation is defined as a shift or displacement in the rhythms or beats from something <em><u>strong and normal</u></em> to something that causes the listener to want the beat to go back to normal.
