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?

0.3 m/s2

1.5 m/s2

6 m/s

12 m/s2

Option B is the correct answer.

Explanation:

In circular motion we have

An object traveling a circular path of radius 5 m at constant speed experiences an acceleration of 3 m/s². We need to find acceleration when radius is 10 m with same speed.

That is here the radius is doubled, we need to find what will happen to acceleration.

Dividing both equations,

Option B is the correct answer.

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
