1. The tip of the minute hand travels 8.377 inches in 10 minutes.

2. The tip of the minute hand travels 33.929 inches in 40.5 minutes.

3. The tip of the minute hand travels 163.2628 inches in 3.25 hours.

Explanation:

On any clock, in 60 minutes the minute hand rotates 360° degrees, so for every 10 minutes, the minute hand rotates an angle of 60°.So first, we calculate the angles rotated in 10 minutes, 40.5 minutes and 3.25 hours.For 10 minutes, the angle rotated is 60°. For every minute, the minute hand rotates an angle of 6° so for half a minute it covers 3°. For 40.5 minutes, it rotates 4 × 60° + 3° = 243°. 3.25 hours equals 195 minutes, angle rotated = 19.5 × 60° = 1170°.Arc length is calculated by using the formula 2πr × (θ/360). r = 8 inches. Arc length for 60° = 2π×8× (60/360) = 8.377 inches. Arc length for 243° = 2π×8× (243/360) = 33.929 inches. Arc length for 1170° = 2π×8× (1170/360) = 163.3628 inches.

Answer from: Quest

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
