Question
Please transfer your choices to the answer sheet by coloring and completely filling the box that represents the choice for each of the questions, which one of the following is an example of a vector quantity? distance velocity mass area 20 Two vectors, of magnitudes 20 and 50, are added. Which one of the following is a possible answer for the magnitude of the resultant?20 40 10 80 A motorist travels for 3.0 h at 80 km/h and 2.0 h at 100 km/h. What is her average speed for the trip?92 km/h 88 km/h 90 km/h 85 km/h the length and width of a rectangle are 1.125 m and 0.606 m, respectively. Multiplying, your them as Rounding properly to the correct number of significant figures, the area should be written as 0.68175 m2. 0.6818 m2 0.68 m2. 0.682 m2. In the equation y^2 = 1/4g^2t^3 is the displacement, the time, and g is the gravitational acceleration. Is it dimensionally consistent? Yes, What is the result of 2.43 4, 561? 5.3278 times 10-1 5.328 times 5.33 times 10-1 5.3 times 10 A bullet is fired horizontally, and at the same instant a second bullet is dropped from the same
Explanation / Answer
Ans(1) A quantity, which has only magnitude and no direction is called scaler quantity and quantity which comprises of both magnitude and direction, is called a vector quantity
Answer is distance and velocity
Ans (2) when we add 20 and 50 then it will lies between 20+50 and 50-20
answer is 40
