In general it is best to conceptualize vectors as arrows in space, and then to make calculations with them using their components. (you must first specify a coordinate system in order to find the components of each arrow.) this problem gives you some practice with the components. let vectors a⃗ =(1,0,−3), b⃗ =(−2,5,1), and c⃗ =(3,1,1). calculate the following, and express your answers as ordered triplets of values separated by commas. a.) a - b =b.) b - c =c.) -a + b - c =d.) 3a - 2c =e.) -2a + 3b - c =f.) 2a - 3(b-c)

Aray diagram for a refracted light day is shown. what does the dashed line represent

What is the magnitude of the resultant vector round your answer to the nearest tenth

Aplane flies a distance d from west to east at a constant speed vp , with respect to the air in a time twe . on the return trip, the plane flies a distance d from east to west at a constant speed vp , with respect to the air in a time tew . on both trips the wind blows from west to east at a constant speed va , with respect to the ground 1) what is tew in terms of vp, va, and d, as needed? tew=dvp tew=dvp+va tew=dva tew=dvpâ’va tew=12dvp tew=12dvp+va tew=12dvpâ’va your submissions: b submitted: saturday, january 26 at 6: 49 pm feedback: feedback will be given once all questions have been attempted and the grade cluster button has been pressed. 2) what is twe in terms of vp, va, and d, as needed? twe=dvp twe=dvp+va twe=dva twe=dvpâ’va twe=12dvp twe=12dvp+va twe=12dvpâ’va your submissions: d submitted: saturday, january 26 at 6: 49 pm feedback: feedback will be given once all questions have been attempted and the grade cluster button has been pressed. 3) assuming d = 2300 miles, vp = 400 miles/hr, and twe = 4 hours, what is va, the speed of the wind with respect to the ground? va = 100 miles/hr va = 575 miles/hr va = 200 miles/hr va = 175 miles/hr va = 975 miles/hr 4) once again, assuming d = 2300 miles, vp = 400 miles/hr, and twe = 4 hours, what is tew, the time it takes the plane to fly a distance d miles from east to west? tew = 5.75 hours tew = 11.5 hours tew = 7.67 hours tew = 8 hours tew = 10.2 hours
