When the load Lis 5.6 m from point C, the tension T in the cable has a magnitude of 8.4 kN. Express T as a vector using the unit vectors i andj Assume a -5.6 m,b=2 m,c=5.1m. Answer: T= 5.397 3622 KN

doesn't that still need to be multiplied by 6?

It's showing that b is not correct. Thank you for your help with this practice problem.

In 1999, NASA lost the Mars Climate Orbiter because one group of engineers used metric units in their calculations while another group used English units. Consequently, the orbiter descended too far into the Martian atmosphere and burned up. Suppose that the orbiter was to have established orbit at 157 km and that one group of engineers specified this distance as 1.57 x 10³ m. Suppose further that a second group of engineers programmed the orbiter to go to 1.57 x 10³ ft. The $125 million Mars Climate Orbiter was lost in the Martian atmosphere in 1999 because two groups of engineers failed to communicate with each other about What was the difference in kilometers between the two altitudes?

calculate the following and express the answer in the proper number of significant figures: (3.245x0.035x9.0023)/(4.076x2.01x42.3)

Estimate the order of magnitude of the length, in meters, of each of the following.

22. Carry out the operation. Express the answer by rounding it off to the correct significant figures. (7.8 0.34) / (1.15 +0.82) - 3.8 3.79 3.78 3.787

Longest to shortest length 10 yards 1 km 50 in 1*10^4 cm

I have tried 16.7x10^3, 16.7x10^4, and 1.365x10^8 and those are all wrong for the first part. I know that the second part is 14.3 hr. I need to know the km/s. Thank you!!
