Answer:

Two of the electrons are in the first energy level while the other five are in the second energy level.

Explanation:

.

An atom of nitrogen has 2 electrons in first energy level and 5 electrons in second energy level.

Electrons present in an atom revolve in different orbits which are stationary states and are also called as energy levels. The energy levels are numbered as integers which are also called as principal quantum numbers.

Energy of the stationary state is given as E= -R

1/n² where R

is the Rydberg's constant. When an electron is excited, and it moves from lower to higher energy levels there is absorption of energy, while when it moves from higher energy level to lower energy level it radiates or gives out energy in the form of radiation.

They can also be defined as the distances between electron and nucleus of an atom . Electrons present in K energy level have least energy .Energy level diagrams are studied to understand nature of bonding , placement of electrons in orbits and and elemental behavior under certain conditions.

Answer:

it would be Individuals get one factor for a trait from each parent. and dominant factor can hide the expression of a recessive factor when both are present.

Mendel discovered about the principles of heredity: A)  Individuals get one factor for a trait from each parent and C)  A dominant factor can hide the expression of a recessive factor when both are present.

Gregor Mendel uncovered the basic principles of inheritance through his study on pea plants. He concluded that genes are inherited from each parent as separate, paired units. Mendel observed how parental genes separated and if they showed up as dominant or recessive qualities in the children. He was aware of the mathematical patterns passed down from one generation to the following.

Mendel's Laws of Heredity are typically expressed as follows:

1) The Law of Segregation: A gene pair determines each inherited trait. So that each sex cell only contains one of a pair of parental genes, parental genes are arbitrarily distributed to the sex cells. Therefore, when sex cells combine to form offspring during fertilisation, they receive one genetic allele from each parent.

2) The Law of Independent Assortment: Different qualities' genes are grouped independently of one another so that inheriting one trait does not affect inheriting another.

3) The Law of Dominance states that an organism with two possible gene variants will express the dominant form.

Answer:

His investigations into optics commenced in 1666 at the end of an annus mirabilis when, at home in Wools Thorpe, Lincolnshire due to the bubonic plague which was raging in Cambridge, he investigated gravity, calculus and the laws of motion. He determined to ‘try therewith the celebrated Phenomena of Color’. It had been thought previously that colour was created by the mixing of light and darkness. Newton noted, however, that the blended print on the white page of a book appears grey, not coloured, when viewed from a distance. His experiments in bending light through prisms led, eventually, to the revolutionary discovery of the existence in white light of a mixture of distinct coloured rays, distinguishable when refracted in a prism. In his first experiment he projected the light via a round hole in his shutters.

Sometimes people refer to Mars as the Red Planet. Because of the rusty iron in the earth, it is red. Mars features weather, polar ice caps, canyons, volcanoes, and seasons just like Earth. Its atmosphere, which is composed of carbon dioxide, nitrogen, and argon, is extremely thin. These define Mars' characteristics.

These are some of the characteristics of the moon, which is the only natural satellite of Earth and the nearest huge celestial body. It is a spherical rocky body that revolves around Earth in a somewhat eccentric orbit at a mean distance of around 384,000 km (238,600 miles), perhaps with a tiny metallic core. It has a 1,738 km (1,080 miles) equatorial radius.

A celestial body inside the Solar System that meets the following criteria is referred to as a "planet": (a) it must be in orbit around the Sun; (b) it must have enough mass to overcome rigid body forces and take on a hydrostatic equilibrium form that is almost circular; and (c) it must have cleared the area in and around its orbit.

Answer:

Space probes are made to conduct science experiments. They do not have people on them. Space probes have helped scientists get information about our solar system. Most probes are not designed to return to Earth. Some have landed on other planets! Others have flown past the planets and taken pictures of them for scientists to see. There are even some space probes that go into orbit around other planets and study them for a long time. The information they gather is used to help us understand the weather and other changes which happen on planets other than the Earth. This information is important in helping to plan other space missions such as ones to Mars and to Saturn.

Explanation:

Answer:

The term "heat" refers to a type of electricity. Joules are the units of measurement. The kinetic energy of an object's particles, as well as the number of particles, affect its temperature. The average kinetic energy of the particles in a material is defined as temperature.

Explanation:

Answer:

- Increase the concentration of the reactants

-increase the temperature

- introduce a catalyst

The rate of reaction is increased by:-

The speed at which a chemical reaction occurs is known as the reaction rate or rate of reaction. It is proportional to the rise in product concentration per unit of time and the fall in reactant concentration per unit of time. Reaction times can differ wildly.

A chemical reaction is a procedure that causes one group of chemical substances to change chemically into another.

The rate of a chemical reaction can be increased by Increasing the concentration of the reactant by increasing the temperature and by introducing a catalyst.

Therefore, the rate of reaction can be increased by doing the actions explained above in the answer.

The variables in this experiment are pressure and volume. So, option c is correct.

Boyle's law states that, the pressure of an ideal gas of a given mass is inversely proportional to its volume at constant temperature.

Here,

The gas is confined to a cylinder with a movable piston, at constant temperature. So, the temperature does not changes. The piston of the cylinder is pushed into it such that the volume of the gas decreases.

According to Boyle's law, the pressure of the gas is inversely proportional to the volume of the gas.

So, as the volume of the gas decreases, the pressure will increase.

This is because, since the the volume of the gas in the cylinder is decreasing, the gas molecules will come closer such that the space for their movement is decreased. As a result, the gas molecules collide with each other and thus resulting in an increased pressure, keeping the temperature constant.

Hence,

The variables in this experiment are pressure and volume.

Climbing a mountain is similar to hiking from the equator to one of the poles is same as in both cases acceleration due to gravity  and weight of the object falls as the object goes far.

The amount of a body's weight indicates how much gravity is pulling on it. Weight is calculated using the method w = mg. Since weight is a force, it has the same SI unit as a force, which is the Newton (N).

When an object climbs a mountain, altitude of the object increases - that's way - acceleration due to gravity and weight of the object decreases. Similarly, when an object hikes from the equator to one of the poles, acceleration due to gravity and weight of the object decreases. In this way, climbing a mountain is similar to hiking from the equator to one of the poles.
