How many significant figures are there in the following measurement
a) 300 000 000 m/s

hi i’m sorry to call us today so we will get back with y’all and we will have to do it haha omg was the day

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
