What will happen to blood cell If valves are not present? When the pulmonary valve is missing or does not work well, blood does not flow efficiently to the lungs to get enough oxygen. In most cases, there is also a hole between the left and right ventricles of the heart (ventricular septal defect). This […]
What are the factors that affect the amount of solar radiation?
What are the factors that affect the amount of solar radiation? In total seven influences on solar radiation have been identified: Solar elevation. Where the sun sits in the sky determines the level of UV radiation reaching us. Ozone. Cloud cover. Ground surface reflectivity. Altitude. Aerosols and pollutants. Direct and diffuse UV. What factors affect […]
When light falls on Prism The result can be?
Can bones bend over time?
Can bones bend over time? Bones can change their shape throughout our life by regulating bone formation and resorption processes, which is often a response to forces which press, pull and twist the skeleton during everyday movements and exercise. Can adult bone bend? Children’s bones can actually bend before they break. An adult bone is […]
Is magnitude and distance the same?
Is magnitude and distance the same? Distance is defined to be the magnitude or size of displacement between two positions. How do you find the magnitude and distance? The magnitude of a vector →PQ is the distance between the initial point P and the end point Q . In symbols the magnitude of →PQ is […]
What is the atomic number of 8 protons and 10 neutrons?
What is the atomic number of 8 protons and 10 neutrons? Fluorine Who uses oxygen? Oxygen therapy is prescribed for people who can’t get enough oxygen on their own. This is often because of lung conditions that prevents the lungs from absorbing oxygen, including: chronic obstructive pulmonary disease (COPD) pneumonia. Can too much supplemental oxygen […]
How do you calculate the force to push an object?
Should carrots float or sink?
Should carrots float or sink? What’s happening in there? The carrot is more dense than fresh water so the carrot sinks in fresh water. When salt is dissolved in the water, the density of the water increases until the salt water becomes more dense than the carrot which makes the carrot float in the salt […]
Can you charge a conductor?
Can you charge a conductor? Explanation: While you can charge a dielectric (non conductive, like plastic) object rubbing, you cannot charge a conductor (like a metal) rubbing. If you add a charge in one zone of the conducting object, the other charges will automatically re-arrange to neutralize the charge. Is salt water an insulator? For […]
Who benefits from photovoltaic cells?
Who benefits from photovoltaic cells? Electricity produced by solar cells is clean and silent. Because they do not use fuel other than sunshine, PV systems do not release any harmful air or water pollution into the environment, deplete natural resources, or endanger animal or human health. Photovoltaic systems are quiet and visually unobtrusive. How long […]
