A 5.1 kg black bear cub weighs 49.98 N. The cub is carried by its mother up into the safety of a white pine tree. How much GPE will the cub have as he rests on a sturdy branch that's 4 m above the forrest ground? How much work did the mother bear do in carrying her cub to this height?

GPE = 199.92 Joules

Work = 199.92 Joules

Explanation:

A 5.1 kg beer cub weighs 49.98N

Mg = F

g = F/M

g = 49.98/5.1

g = 9.8 m/s²

GPE = mgh

GPE = 5.1 * 9.8 * 4

GPE = 199.92 Joules

The work done by the mother is equal to the GPE , because

Force*distance = work

Force = 49.98N

Distance = 4m

Work = 199.92 Joules

true tan speed = ang vel x radius

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.
