In SQL, BETWEEN Keyword is used for ranges like Number Ranges, Date Ranges, etc...

The freezing point of water and melting point is 0 °C or 32 °F. The temperature may be lower if supercooling occurs.

The interval between object pass the same point is 4 sec.

That means in 2 sec, object reaches the top and in next 2 sec, it again reaches the same point.

By the info given, we can find the velocity of that point by using : v=u+(-gt)

0= u - 10×2

u = 20

Then the velocity at 25m is 20m/sec.

so the initial velocity is

$$\begin{gathered} -v2 = u2 + (-2gh) \\ 400 = u2 - 2x 10 x 25 \\ u2 = 900 \\ => u = 30 m/s \end{gathered}$$

Hubs regenerate electrical signals, which are specified at the Physical layer.

Market failure arises because it is not possible for the market to correctly weight cost and benefits in a situation in which some of the cost is completely unaccounted.

Demand-side market failures happen when demand curves do not reflect consumer’s full willingness to pay for goods or services.

Supply-side market failures occur when supply curves do not reflect the full cost of producing a good or services.

The basic unit of the nervous system is the Neurons.

The neuron is a single nerve cell, and you have billions of them.

There are three basic types of neurons::

1. Association,

2. Afferent  and

3. Efferent.

The association neurons comprise the central nervous system (CNS) that is the brain and spinal cord.

The afferent neurons are also known as the sensory neurons, they bring the stimuli from the sensors (e.g., skin, eyes, ears) to the CNS.

The efferent neurons are also known as motor neurons, they bring the responses from the brain to the muscles and the glands.

The amount of water vapor ranges from a trace amount up to 4% of the mass of air. Water vapor exists as an invisible gas in the air.

The amount of water vapor in the air is called absolute humidity. The amount of water vapor in the air as compared with the amount of water that the air could hold is called relative humidity.

The maximum amount of water vapor that can be in the air depends on the air temperature.
