The heart is a muscular organ composed of 4 chambers; the left atrium and RIGHT atrium (pl. atria) and the left ventricle and right ventricle (pl. ventricles). The left and right sides of the heart are separated by a septum. The right atrium receives deoxygenated blood through the vena cava. After passing through the tricuspid VALVE, the right ventricle pumps this deoxygenated blood out through the pulmonary artery to the lungs. This is called the pulmonary circuit. Simultaneously, the left atrium receives oxygenated blood, from the lungs, through the pulmonary vein. Once this oxygenated blood passes through the bicuspid valve and into the left ventricle, it is pumped out through the aorta to the rest of the body. This is called the systemic circuit. Valves act to partition the atria from the ventricles but most importantly prevent the BACKFLOW of blood. STRUCTURALLY, the left wall of the heart is thicker hence maintains a higher blood pressure COMPARED to the right side of the heart. All in all, humans have a double circulatory system through which blood is pumped by the heart to supply cells of the body.

ecreases its speed from 80 km/h to 60 km/h in 5 s. Given that, starting speed means the initial velocity (U) of the bus is 80 km/hr.And ending or final velocity (v) of the bus is 60 km/hr.Also given that, time (t) is 5 seconds.We have to find the ACCELERATION of the bus. Using First Equation of Motion i.e.v = u + atGiven time is in seconds and speed is in km/hr. So, CONVERT the speed in m/s.Initially velocity (u) = 80 × 5/18 = 22.22 m/sFinal velocity (v) = 60 × 5/18 = 16.67 m/sSubstitute them in the above formula→ 16.67 = 22.22 + a(5)→ 16.67 - 22.22 = 5a→ -5.55 = 5a→ -1.11 = a(Negative SIGN shows the deceleration or retardation)Therefore, the deceleration of the bus is -1.11 m/s².

In GEOMETRIC optics, the paraxial approximation is a small-angle approximation used in GAUSSIAN optics and ray tracing of LIGHT through an optical system. A paraxial ray is a ray which MAKES a small angle to the optical axis of the system, and LIES close to the axis throughout the system.MARK IT BRAINLIEST...

Dividing this NUMBER into 1 yields the number of times the point oscillates each second, which is the frequency of the wave. Multiplying the wave's frequency by its WAVELENGTH, which is its physical length, yields the velocity of the wave. The relationship can be expressed as velocity equals frequency times wavelength.Explanation:SEE THE ATTACHMENT ALSO..

according to your question. ...the FINAL and the INITIAL velocity will be same....because as we KNOW that the ACCELERATION is the RATE of change in velocity. .so as there is no acceleration. .it means that the initial and the final velocity will be same....hope it helps

Resistance also becomes doubled.If the resistance was RΩ then now, it will BECOME 2RΩ .Explanation:W.K.T, R = ρl/A           R  ∝ L       So, when l INCREASES, even R increases.So, when l becomes 2l, R becomes 2R.

Zaitsev's rule (or Saytzeff's rule, Saytzev's rule) is an empirical rule for predicting the favored alkene product(s) in ELIMINATION reactions. While at the University of Kazan, Russian chemist Alexander Zaitsev studied a variety of different elimination reactions and observed a general trend in the resulting alkenes. Based on this trend, Zaitsev stated, "The alkene formed in greatest AMOUNT is the one that corresponds to removal of the HYDROGEN from the alpha-carbon having the fewest hydrogen substituents." For example, when 2-iodobutane is treated with alcoholic potassium hydroxide (KOH), 2-butene is the major product and 1-butene is the minor product.[1]A general example of Zaitsev's rule.More generally, Zaitsev's rule predicts that in an elimination REACTION, the most substituted product will be the most stable, and therefore the most favored. The rule makes no generalizations about the stereochemistry of the newly formed alkene, but only the regiochemistry of the elimination reaction. While effective at predicting the favored product for many elimination reactions, Zaitsev's rule is subject to many exceptions.please mark as brainliest ANSWER

The velocity of the SOURCE (v_s) is v / 4 (or) 82.5 m/sGiven:LET the NATURAL Frequency be " f₀ "Apparent Frequency (f_a) = 4 / 3 f₀Let the speed of the sound be " v "Explanation:From the formula we know,Here,f_a Denotes apparent Frequencyf₀ Denotes Natural Frequency.v Denotes Speed of sound.v_s Denotes velocity of source.Now,As the source is moving towards the observer,Then at the denominator there will be NEGATIVE sign.Substituting the values and solving,∴ The velocity of the source (v_s) is v / 4 (or) 82.5 m/s.

e the characteristics of particles of matter?The particles are very, very tiny in size. Matter particles have space in between them. The particles of matter SHIFT continuously. The Matter Particles attract each other.A gas fills completely the vessel in which it is kept answerA gas completely fills the vessel in which it is kept because there is negligible force of attraction between the particles of gas. Thus, the gas particles move freely in all directions. Are the three states of matter interconvertible how are they interconnectDepending on temperature and pressure levels, matter can exist in one of the three main states, i.e., solid, liquid, or gas. Matter can be inter converted by adding or removing heat energy from one STATE to another. Both three substantive states are inter-convertible.How does evaporation causes coolingEvaporation causes cooling because the process requires heat energy. The energy is taken away by the molecules when they convert from liquid into gas, and this causes cooling on the original SURFACE.Why should we wear cotton clothes in summerWe wear cotton clothes during summer as cotton absorbs sweat from the body, exposing to the atmosphere for easy evaporation. As we tend to sweat more during summer and cotton fabric absorbs sweat and help body to cool down.Why it is that a wooden chair should be called a solid not a liquidBecause a wooden chair is a solid and solids have least inter particle space between their molecules while in liquids they have less inter particle space between their molecules as compared to solids and solids have definite shape like a wooden chair but liquids have not.So a wooden chair is a solid.what is evaporation what are the factors AFFECTING itEvaporation is the process of a liquid turning into gas due to absorption of heat. factors affecting evaporation are: Temperature Surface area of the liquid exposed to the atmosphere Wind speed and Humidity.What happens when we apply pressure to the particles of matterThe particles will get packed and draw nearer to each other and free vitality and their Kinetic Energy additionally decreases. They change their state from gas to fluid and afterward into strong. Heat vitality will be discharged.When heat is being applied to a solid, then what does the heat energy do to the particles of matters? -As we heat any substance it gains internal energy which is a function of temperature. The heat energy added INCREASES the lattice vibrations inside the material.PLEASE MARK ME AS BRAINLIEST IF YOU ARE HAPPY WITH THE ANSWER
