Answer:

<u>Option-(A): </u>A new moon is quite near the Sun in the sky.

Explanation:

  • While the position of the new moon inside our sky has such an orientation that we are not able to see or observe the actual position and shape of the new moon.
  • As the path or revolution is much more elliptical then we can imagine, for the moon there are certain position of motion inside the celestial space that for some times it looks for different then the other and such position generates the concept of a new moon.

If a cart goes around a turn at 20 km/h ,what remains constant
Vitek1552 [10]

Answer: 4.speed

Explanation:

In this case, we know that the cart remains at a constant 20km/h.

Now, one could say that "the velocity remains constant, because it always is 20km/h"

But remember that velocity is a vector, so this has a direction, and if the cart is going around a turn, then the direction of motion is changing, which tell us that there is acceleration.

But the module of the velocity, the speed, remains constant at 20km/h.

Then the correct option is 4, speed.

Diamond and graphite are both composed entirely of carbon yet graphite is soft and diamond is one of the hardest substances know
pogonyaev

Explanation:

This difference is because of the difference in arrangement of carbon atoms both graphite and Diamond.

Carbon atoms in graphite are arranged in layered form in an infinite array of layers. These layers are held together by a weaker force of attraction called vander waal's force of attraction such that layer's can slip over one another. Whereas in diamond carbon atoms are arranged tetrahedrally. Each carbon atom is attached to four carbon atoms with a bond angle of 109.5°. It is strong rigid three dimensional structure that results in infinite array atoms. This accounts for hardness of the diamond.

Augie created this chart about the two kinds of waves. Which best labels the chart? Title 1 is "Longitudinal Waves," and Title 2
PIT_PIT [208]

Answer:

Explanation:

There are three types of waves mainly.

1. Mechanical waves : Which needs a medium for there propagation. For example, sound waves

2. Non mechanical waves : Which do not need a medium or their propagation.

for example, light waves

3. Electromagnetic waves : Which are produced due to the interaction of electric and magnetic field. for example, X rays, light waves

The wave motion are of two types.

1. Transverse wave motion

2. Longitudinal wave motion
