Which best describes the shape of the magnetic field from a long straight wire carrying a current? The Magnetic field lines around a straight conductor carrying current are concentric circles whose centres lie on the wire. The direction of magnetic field lines can be determined using Right-Hand Thumb Rule. How can you determine the direction […]

Why is Carnot engine Impossible?
Why is Carnot engine Impossible? The conceptual value of the Carnot cycle is that it establishes the maximum possible efficiency for an engine cycle operating between TH and TC. It is not a practical engine cycle because the heat transfer into the engine in the isothermal process is too slow to be of practical value. […]

Why is it important to have a cardiovascular endurance?
Why is it important to have a cardiovascular endurance? Cardiorespiratory endurance tests monitor how well the heart, lungs, and muscles perform during moderate to high-intensity exercise. Increasing cardiorespiratory endurance improves oxygen uptake in the lungs and heart and can help a person sustain physical activity for longer. How long does it take to make exercise […]
Why is plate tectonic a theory?
Why is plate tectonic a theory? The theory of plate tectonics states that the Earth’s solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. Thus, at divergent boundaries, oceanic crust is created. What are the basic assumptions of the plate tectonics theory? Two […]
Is there a magnet that can pick up gold?
What is the unit of intensity of light?
What is the unit of intensity of light? candela Which is respond to intensity of light? The retina is the back part of the eye that contains the cells that respond to light. These specialized cells are called photoreceptors. There are 2 types of photoreceptors in the retina: rods and cones. What is intensity a […]
Is UV-C blocked by ozone?
Is UV-C blocked by ozone? UV-C is completely absorbed by the ozone layer, which is fortunate since humans have no natural defense against this kind of radiation. Is UV-A light safe? UVA rays cause tanning, and the shorter wavelengths of UVA also cause sunburn. There is no such thing as a safe or healthy tan. […]
What are the three parts of a gene?
What are the three parts of a gene? Genes consist of three types of nucleotide sequence: coding regions, called exons, which specify a sequence of amino acids. non-coding regions, called introns, which do not specify amino acids. regulatory sequences, which play a role in determining when and where the protein is made (and how much […]
