Amotorcycle has a constant speed of 22.7 m/s as it passes over the top of a hill whose radius of curvature is 179 m. the mass of the motorcycle and driver is 342 kg. find the magnitude of (a) the centripetal force and (b) the normal force that acts on the cycle.

On the hill, (a) the centripetal force is , approximately and on the top of the hill, (b) the normal force exerted on the cycle is .

Explanation:

In this case, uniform circular movement equations are suitable, then (a) the centripetal force is given by

Now, (b) at the top of the fill, where weight alligns with the centripetal force and the normal, by applying Newton's second law, we have

.

c)as speed changes, wavelength and frequency change.

everything changes!

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.
