Asolar sailplane is going from earth to mars. its sail is oriented to give a solar radiation force of frad = 8.60 × 102 n. the gravitational force due to the sun is 173 n and the gravitational force due to earth is 1.00 × 102 n. all forces are in the plane formed by earth, sun, and sailplane. the mass of the sailplane is 15,000 kg.

magnitude - 659.91 N

direction = 27.69 degree

Explanation:

The gravitational force due to sun is

Fs = 173 N

Fax = -173 N, Fay = 0 N

Gravitational force is

Fgx = 0 N

Fgy

Assume Solar radiation force at an angle of 30 degree on sail plane is

TOTAL FORCE  in x diretion= -173 + 0 + 744.48 = 571.48 N

and total force in y direction is

Fy = 0 - 100 + 430 = 330 N

Magnitude of force  

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
