Calculator Assumed - Question 1 The wind chill index \( I \) is a measure of how quickly a person exposed to a wind will lose heat. It is calculated using the formula below, where \( v \) is the speed of the wind in metres per second and \( T \) is the air temperature in degrees Celsius. \[ I=(10 \sqrt{v}-v+10.2)(34-T) \] (a) Determine \( I \) when the air tempęature is \( -3^{\circ} \mathrm{C} \) and there is a wind of \( 12 \mathrm{~m} / \mathrm{s} \) blowing.
