An archer's bow is drawn at its midpoint until the tension
inthe string is 1.20 times the force exerted by the archer. what
isthe angle between the two halves of the string?

θ= 131° and in radian  rad = 2.27  

Explanation:

We have find the angle as the tension in the string is 1.20 times the force.

as We have

F = 2.T.cos(θ/2)  

Angle can be found as

θ = 2×cos⁻¹(1/(1.2×2))2 times because angle between the two halves of the string

θ= 131° and in radian  rad = 2.27

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.

compass can be used day and night, cloudy or sunny
