What is the relation between force and mass? A: Force is mass times acceleration, or F= m x a. This means an object with a larger mass needs a stronger force to be moved along at the same acceleration as an object with a small mass. This is Newton’s Second Law of Motion. What will […]

What is limitation of model? Models are used to simulate reality and make predictions. The major limitation of models is that they are ‘idealizations’ or ‘simplification’ of reality and thus cannot possibly replace reality. A number of assumptions are made during modeling and this causes differences between model and reality. What are some model limitations? […]

How does a human presence sensor work? Sensors Powering Human Presence Detection Ambient light sensors: As the name suggests, these sensors detect light in the environment. They can measure the light reflecting from an approaching user to detect human presence from a distance. How does a presence sensor work? Presence sensors/motion sensors actually detect the […]

What is the Hydra in real life?

Where does friction act on a wheel? The friction force acts in the forward direction on the rear wheel and it acts in the backward direction on the front wheel. The magnitude of friction force on the rear wheel can be more, equal or less than that on the front wheel. How does friction affect […]

Which is one reason for the formation of global winds quizlet? Global winds are caused by the uneven heating of earth’s surface and the Coriolis. What are 2 examples of global winds? The four major wind systems are the Polar and Tropical Easterlies, the Prevailing Westerlies and the Intertropical Convergence Zone. These are also wind […]

What is the load of 1 ton AC? cooling capacity of 1 ton is equal to 3.517 kW of power. =1.5*3.517/2.7=1.954 kW. AC consists of two units, Indoor unit which is called the evaporator and the Outdoor Unit which called the Compressor. How many units does a 1 ton AC consume in an hour? 1.0 […]

What are values of a scientist? Those surveyed, using a scale from zero to ten, were asked to rate attentiveness, collaborative, courage, curiosity, honesty, humility to evidence, meticulousness, objectivity, perseverance and skepticism with regard to their importance for scientific research. What is the value of science in our life? In other words, science is one […]
