At which three points x1, x2, and x3 closest to x=0 but with x> 0 will the displacement of the string y(x, t) be zero for all times? these are the first three nodal points. express the first three nonzero nodal points as multiples of the wavelength λ, using constants like π. list the factors that multiply λ in increasing order,

answer: i believe c. is the answer sorry if i am wrong

step-by-step explanation:

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this

the correct answer is c
