How do I find the magnitude from this data: theta_1 = 44.9 theta_2 = 146.1 A = 4.8 cm B = 8.7 cm

A river flows due east at 1.65 m/s. A boat crosses the river from the south shore to the north shore by maintaining a constant velocity of 10.7 m/s due north relative to the water. What is the velocity of the boat relative to shore?

Under acidic conditions, MnO4− becomes Mn2+. Write the balanced half-reaction for this transformation. (Omit states-of-matter from your answer.)

A baseball player exert a force of 125 N on a 0.18 kg baseball for 33 sec. what is the baseball change of momentum ?

if 3 mole of of calcium react with 3 mole of oxygen then what substance is limiting reactant?

.6 .16

of vector (A + B)

theta one goes with A and theta two goes with B. I know I'm supposed to use |A+B| =sqrt[ (A+B)x^2 + (A+B)y^2 ], but I am having troubles on which numbers I have to plug in for each value.

I keep getting the wrong answer. I got 4.42, is that wrong?

part B: If the river is 308 m wide, how far downstream has the boat moved by the time it reaches the north shore?

Part A keeps be marked wrong. Is my answer supposed to be 493.7 N ?
