Define scalar quantity. give two examples
WebIt is obtained by multiplying the magnitude of the given vectors with the cosine of the angle between the two vectors. The resultant of a vector projection formula is a scalar value. Let OA = → a a →, OB = → b b →, be the two vectors and θ be the angle between → a a → and → b b →. Draw AL perpendicular to OB. WebThe length of an arrow represents the magnitude of the quantity. If one arrow is twice as long as another, it represents a force which has twice the magnitude. The diagrams show three examples of ...

WebSep 20, 2024 · Examples of scalar quantities. Temperature . Depending on the scale used (Celsius or Kelvin), each numerical value will represent an absolute magnitude of (presence or absence of) heat, so that 20 ° C constitute a fixed value within the scale, regardless of the conditions that accompany the measurement. The pressure. WebAnswer: The scalar product of vectors a = 2i + 3j - 6k and b = i + 9k is -49. Example 2: Calculate the scalar product of vectors a and b when the modulus of a is 9, modulus of b is 7 and the angle between the two vectors is 60°. Solution: To determine the scalar product of vectors a and b, we will use the scalar product formula.

WebDerived physical quantities are the properties of an object that result from two elemental physical quantities. Derived quantities can result from a relationship of the same physical quantity (e.g. area) or by relating two different ones (e.g. velocity). See below for some examples of derived physical quantities. Area and volume: related to length:
