Question

What is the reading on the vernier caliper above? 1.370cm 1.61cm 0.83cm 1.630cm Applying regression on data involves adopting a linear fit that best describes the relationship between two variables. quadratic linear hyperbolic linear fit The slope of a position-lime graph represents the constant motion acceleration distance velocity Use the component or analytical method to find the magnitude and direction of the resultant vector R of adding the following vectors: Vector A: 50g at 90 degrees Vector B:120g at 100 degrees 170 at 190 degrees 169g 97 degrees 70g at 10 degrees 162g at 85 degrees

Explanation / Answer

6.Main scale reading = 1.6cm

vernier co-incidence division=6

reading = m.s.r + v.s.d*l.c = 1.6 + 6*0.005 = 1.630cm (D)

7. (B) Linear

8. slope of position graph = (x2-x1)/(t2-t1) = velocity (D)

9.magnitude = sqrt(2500+14400 + 2*50*120*cos(10)) = 169.46g

direction=97 degrees
