How many total lunar eclipses are there every year.

Answer:

the answer to your question is b a mirror fogs up when someone takes a hot shower.

The process of conversion of gaseous water to its liquid form is called condensation. The fogs formed on the mirror from the hot shower is an example of condensation.

Condensation is the process of cooling up of water vapor to liquid water. Water vapor condenses when it cools. Condensation can be best understood from the reason behind raining.

When water vaporizers from resources and cools from the sky, and the vapor condenses to form liquid droplets. Similarly we can observe water droplets in the window pane due to the similar effect.

The water vapor arises from the hot shower condenses in the atmosphere and forms the drops on the mirror. Therefore, the mirror fogs up by the hot shower is an example of condensation.

Answer:

A

Explanation:

Because plants cant move and animals can.

The characteristic which describes an organism of kingdom Animalia is able to move on its own when compared to the plants kingdom. Thus, the correct option is A.

Animals are the multicellular, eukaryotic organisms in the biological kingdom Animalia. Animals are the organisms which consume organic material, breathe oxygen gas, are able to move on their own, can reproduce sexually and produce organisms which contain genetic information which is recombination of both the parents, and these organisms go through an ontogenetic stage in which their body consists of a hollow sphere of the cells, the blastula, during the embryonic development of organisms.

Organisms belong to Animal kingdom show some characteristics which are not found in the organisms which belong to the plant kingdom including movement. Animals can move on their own while plants cannot.

Question: Exposure to a sufficient quantity of ultraviolet will redden the skin, producing erythema - a sunburn. The amount of exposure necessary to produce this reddening depends on the wavelength. For a 1.0 cm2 patch of skin, 3.7 mJ of ultraviolet light at a wavelength of 254 nm will produce reddening; at 300 nm wavelength, 13 mJ are required. Part A What is the photon energy corresponding to each of these wavelengths.

The acceleration that is produced by the 2 Kg force is 12 m/s^2.

We know that from the Newton first law, it is the magnitude of the force that is imparted to a body that produces the given acceleration. It is now safe to say that the force that is exerted on a body is directly proportional to the acceleration of the body. This is the fall out that we can take from the Newton law as stated above.

In this case, we have seen that the Two friction less blocks, having masses of 8.0 kg and 2.0 kg, rest on a horizontal surface.

Now;

F = ma

F  = force

m = mass

a = acceleration

F = 8.0 kg *  3.0 m/s2

F = 24 N

We are told that the same force was applied to the 2 Kg mass

a = F/m

If the ignition switch is moved from both to either left or right during an engine ground check, normal operation is usually indicated by a slight drop in RPM

The number of rotations in one minute is known as RPM revolutions per minute (abbreviated rpm, RPM, rev/min, r/min, or with the notation min1). It is a measure of rotational frequency or speed around a fixed axis.

Since there are 60 seconds in a minute and one revolution is 360 degrees, revolutions per minute RPM can be multiplied by 6 to get angular velocity in degrees per second. Since 6 times 1 is 6, the angular velocity in degrees per second if the rpm is 1 rpm would be 6 degrees per second.

If our body were not held together by electromagnetic forces and only subject to the expansion of the universe, the time it would take for us to grow by 10 cm due to the expansion would depend on the rate of expansion.

However, at the scale of our bodies, the expansion of the universe is negligible. The expansion of the universe primarily affects the large-scale structure of the cosmos, such as the separation between galaxies.

On everyday scales, the gravitational forces within and between objects are much stronger than the expansion of the universe. These gravitational forces hold objects together and keep them from being affected by the overall expansion. For example, the gravitational force between the atoms and molecules in our body is much stronger than the expansion, so we do not experience any noticeable growth due to the expansion of the universe.

The expansion of the universe becomes significant at much larger scales, such as the separation between galaxy clusters or superclusters. At these scales, the expansion can overcome the gravitational forces and affect the overall structure of the universe.

The theory describes electrons in experiments, but the electron cloud model theory has limitations in its ability to provide precise information about the exact position and trajectory of electrons in an atom.

This is due to the inherent probabilistic nature of electron behavior, as described by quantum mechanics. The electron cloud model represents the probability distribution of finding electrons in certain regions around the nucleus but does not provide specific information about the precise paths or orbits they follow.

On the other hand, a law about electrons would typically focus on the observed behavior or relationships of electrons rather than attempting to describe their precise positions or trajectories.

Laws, such as the law of conservation of charge or the law of electric current, provide general principles or rules that govern electron behavior within a given context. They are empirical observations derived from experimental evidence rather than detailed theoretical models.

To calculate the volume of the girl's body, we can use the formula V = m/ρ, where m is the mass of the girl and ρ is her average density. Plugging in the given values, we get V = 23.6 kg / 983 kg/m³ = 0.024 m³.

The pressure exerted by the girl's weight on the horizontal surface can be calculated using the formula P = F/A, where F is the force exerted by her weight and A is the area of her two feet. To find the force, we can use the formula F = mg, where m is the girl's mass and g is the acceleration due to gravity (9.81 m/s²). Plugging in the given values, we get F = 23.6 kg * 9.81 m/s² = 231.516 N.

The strongest ebb tidal current is expected around the time of the lowest low water, which is at 4:45 AM on Day 2.

The strongest ebb tidal current would be expected around the time of the lowest low water, which occurs at 4:45 AM on Day 2.

This is because the ebb tide is caused by the outflow of water from an estuary or bay to the ocean, and this outflow is typically strongest around the time of low water.

As the tide ebbs, the water level in the estuary or bay falls, creating a pressure gradient that drives water out to the ocean. This pressure gradient is greatest when the water level in the estuary or bay is at its lowest point.

Therefore, the strongest ebb tidal current would be expected to occur around the time of the lowest low water, which is at 4:45 AM on Day 2 in this case.
