The angle of reflection for monochromatic X-rays from a crystal whose atomic spacing is 2.5 A° is 15°. calculate the wavelength of X-rays.

Answer»

elength of X-rays will be 1.294 A°Explanation : GIVEN,angle of REFLECTION of x-rays , θ = 15°atomic spacing of x-rays, d = 2.5 A° = 2.5 x 10⁻¹⁰ mwe know that,2dsinθ = nλfor n = 1=> λ = 2dsinθ=> λ = 2 x 2.5 x 10⁻¹⁰ x sin15° => λ = 2 x 2.5 x 10⁻¹⁰ x 0.2588=> λ = 1.294 x 10⁻¹⁰ m = 1.294 A°Hence the WAVELENGTH of X-rays will be 1.294 A°I hope it helps.

Ankita saw a crane lifting up iron pieces without the help of a hook. She was amazed to see it. Her friend Richa explained to her how this was possible. This satisfied the curiosity of Ankita

Answer»

due to the electromagnets used on cranes. An electromagnet is a soft metal CORE MADE into a magnet by the PASSAGE of electric current through a coil surrounding it.Electromagnets are based on the magnetic effect of current and electromagnets show magnetic properties only as long as the electric current flows through the coil. These are temporary magnets. These are of very high strength and can be made easily. These are used on cranes for lifting heavy LOADS. Hope, this helps you! Please mark me ANSWER as the Brainliest!

How does deforestation lead to reduction of soil fertility?

Answer»

and subsequently harvesting trees removes nutrients, like phosphates, from the system. The removal of the vegetation that would also normally act as a protective cover and windbreak increases the raindrop impact and wind velocity, whilst simultaneously decreasing the humus content. This accelerates soil erosion from wind and rain splash. Reduced humus content means there is less infiltration and the soil is looser, and so is more easily eroded and REMOVED from the area in runoff. Removal of root SYSTEMS reduces the root binding effect that gives the soil structure and holds it together. A further impact of deforestation is the reduced evapotranspiration rate, leading to decreased humidity and THEREFORE reduced regional rainfall – contributing to ACCELERATED desertification. These cumulative EFFECTS result in a reduction in the nutrient content of the soil and also in the depth of the layer of fertile topsoil.

Describe the structure and functioning of the Heart❤

Answer»

re of the HeartThe heart can be found at the center of the CHEST, underneath the sternum in a thoracic compartment. It is made up of FOUR chambers and several valves that regulate the normal flow of blood within the body.Two chambers called ATRIA are located in the upper portion of the heart and receive oxygen-free blood. The valves that separate these chambers are called atrioventricular valves which is composed of the tricuspid valve on the left and the mitral valve on the right.On the other hand, ventricles are chambers found on the lower portion of the heart; they pump oxygen-enriched blood into all organs of the body, reaching even the smallest cells. Similar to the atria, the VENTRICULAR chambers are also separated by valves. Collectively-termed as semilunar valves, these are comprised of the pulmonary and aortic valve.The functions are hereThe heart is a pump, which moves the blood. The arteries and veins are the pipes through which the blood flows. The lungs provide a place to exchange carbon DIOXIDE for oxygen. The heart is a hollow, muscular organ, which functions as a pump for the movement of blood through the body.

Answer»

which the body needs, comes in. The first step in this process is breathing in air, or inhaling. Inhalation means bringing air rich in oxygen into the body. ... Finally, the CARBON dioxide from cellular respiration is breathed out of body from the lungs. Respiration involves taking in oxygen and release of carbon dioxide by the process of breathing. The taken oxygen is the utilised to oxidise chemical energy stored in the food to released energy in the FORM of ATP along with carbon dioxide and water. Respiration involves exchange of gases i.e. oxygen with carbon dioxide. Respiration in human beings takes place through a special SYSTEM called as respiratory system.This involves NOSTRILS, nasal cavity, larynx, bronchi, BRONCHIOLES ending in alveoli.
