An object traveling a circular path of radius 5 m at constant speed experiences an acceleration of 3 m/s2. If the radius of its path is increased to 10 m, but its speed remains the same, what is its acceleration?

New acceleration = 1.5 m/s²

Explanation:

The acceleration of an object when it moves in a circular path is given by :

Where

v is speed of an object

r is radius of path

If v remains constant,

or

Put r₁ = 5 m, a₁ = 3m/s², r₂ = 10 m

Hence, if the radius of its path is increased to 10 m, its acceleration will be 1.5 m/s².

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
