3. A mystery planet in another part of the galaxy has an acceleration due to gravity of 5.0 m/s. If the radius of this planet is 2.0 x 10 m, what is its mass?

i don't understand is there any other way you can rephrase it plz let me know in the comments and i will do it.

explanation:

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000

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.
