Answer: are breathing much faster
Explanation:
Exercise is a physical activity which increases the rate of respiratory and cardiovascular activity of the body. The cardiovascular exercise is likely to increase the rate at which the heart pumps blood as the body faces the scarcity of oxygen in the muscles which conducts the exercise. This increases rate of breathing so as to acquire more amount of oxygen. The oxygenated blood is pumped by the heart to all the parts of the body.
Answer:
The hottest objects with temperatures in the millions of Kelvins, give off most of their radiation in the form of X-rays and gamma rays.
Explanation:
The electromagnetic (EM) spectrum contains radio waves, microwaves, infrared light, visible light, ultraviolet light, X-rays and gamma-rays. All these different types of radiation are made up of photons having specific wavelengths and different amounts of energy. In the EM spectrum, the photons of radio waves have the lowest energy and the energy of photons increases through microwaves, infrared, visible light, ultraviolet, X-rays, and the photons of gamma-rays have the highest energy (the energy of photons is measured in electron volts).
All warmer objects such as stars, planets, etc emit photons having a specific range of wavelengths and it depends on the surface temperature of those objects. The very hot objects with temperatures in the millions of Kelvins or more mainly emit photons with shorter wavelengths, such as gamma rays and X-rays while cooler objects emit radiation such as infrared or radio waves, having longer wavelengths.
The ultraviolet radiation has the energy in the range of a few electron volts to about 100 eV. The energy of X-ray photons is in the range of 100 eV to 100 keV and the energy of gamma-rays is greater than 100 keV. The nuclear explosions, radioactive decay, the hottest and most energetic objects in the universe such as neutron stars, supernova explosions, etc produce gamma rays.
Objects with temperatures in the millions of Kelvins emit most of their radiation in the X-ray and gamma-ray parts of the electromagnetic spectrum.
Objects with temperatures in the millions of Kelvins primarily give off most of their radiation in the X-ray and gamma-ray parts of the electromagnetic spectrum. As an object's temperature increases, the wavelengths of radiation it emits become shorter. This phenomenon is described by Wien's displacement law.
At lower temperatures, such as those found on Earth or in stars like our Sun, objects emit most of their radiation in the visible and infrared parts of the spectrum. However, as temperatures rise to millions of Kelvins, the emitted radiation shifts to shorter wavelengths, eventually falling into the X-ray and gamma-ray regions.
In the X-ray and gamma-ray parts of the electromagnetic spectrum, radiation has extremely high energy and short wavelengths. These types of radiation are associated with the very high temperatures and intense energy found in extremely hot objects, such as the cores of massive stars, supernovae, and certain high-energy astrophysical phenomena. Scientists use X-ray and gamma-ray telescopes to study these extreme environments and the radiation they emit.

d. 225N
B. Lenient discipline and fewer rules
C. A stable home and varied activities
D. Early instruction in reading
Answer: Option (C) is the correct answer.
Explanation:
The term IQ stands form intelligent quotient. When a child is provided with stable home environment in which there are less or rare conflicts, happy environment, understanding between individuals etc will lead to a stable growth of child.
Also, varied activities will help child to learn quickly and develop various skills.
Thus, a stable home and varied activities is the one parenting factor which is associated with improved IQ scores in children.
