What 3 places on earth do convection currents occur? Convection currents occur within: the atmosphere – wind. the hydrosphere – ocean currents. How convection takes place in the mantle? The mantle is heated from below (the core), and in areas that are hotter it rises upwards (it is buoyant), whereas in areas that are cooler […]

Which rule of Fleming can be used to determine the direction of induced 1 current in the secondary coil if current in the primary coil is changed? Fleming’s Right hand rule – If the forefinger, second (central) finger and thumb of the right hand are stretched at right angles to each other, with the forefinger […]

What are daily necessities? A traditional list of immediate “basic needs” is food (including water), shelter and clothing. Many modern lists emphasize the minimum level of consumption of “basic needs” of not just food, water, clothing and shelter, but also sanitation, education, and healthcare.

How do you determine incidence? Therefore, the term ‘person-year’ was used, which was defined as the number of quarters of the year that a patient was registered in a general practice. Incidence rates were calculated as the sum of all new episodes of illness of a certain disease in 2012 divided by the size of […]

Can you solve physics problems? Multiply and divide the quantities until the units match the units of the answer quantity. For example, if you’re trying to find Potential Energy (kg*m2/s2) and you have the height (m), mass (kg) and gravitational acceleration (m/s2), you can match the units by multiplying the three quantities (m*kg*m/s2=kg*m2/s2). How do […]

Which direction is relative to magnetic field? The direction of the force due to a magnetic field is perpendicular to the direction of motion. distance away from the wire, and is called the permeability of free space. Magnetic fields are measured in Teslas(T). Why are iron atoms affected by magnetic fields? Iron atoms are ferromagnetic […]

What is the best geometric shape? Triangles Whats stronger circle or triangle? The answer is the triangle, because of the way it distributes pressure. I’m assuming you’re referring to an equilateral triangle? The circle ie the strongest shape because it maintains constantly pressure , There is no inherent leverage as all points are at a […]
