Aboy pulls with a 20 n force, at a 20 degree incline. what part of the force moves the wagon?

horizontal direction force move wagon at  18.79 N

Explanation:

given data

force F = 20 N

angle = 20 degree

to find out

What part of the force moves the wagon

solution

we know here as per attach figure

boy pull a wagon at force 20 N at angle 20 degree

so there are 2 component

x in horizontal direction i.e  F cos20

and y in vertical direction i.e F sin20

so we can say

horizontal direction force is move the wagon that is

horizontal direction force = F cos 20

horizontal direction force = 20× cos20

horizontal direction force = 18.79 N

so horizontal direction force move wagon at  18.79 N

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.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
