Light with an intensity of 1 kW/m2 falls normally on a surface and is completely reflected. The radiation pressure is:1. 1kPa2. 3×1011Pa3. 1.7 × 10−6 Pa4. 3.3 × 10−6 Pa5. 6.7 × 10−6 Pa
Light with an intensity of 1kW/m2 falls normally on a surface and is completely absorbed. The radiation pressure is:1. 1kPa2. 3×1011Pa3. 1.7 × 10−6 Pa4. 3.3 × 10−6 Pa5. 6.7 × 10−6 PaThe answer is D, but I don't know why.
A certain wire stretches 0.90 cm when outward forces with magnitude F are applied to each end. The same forces are applied to a wire of the same material but with three times the diameter and three times the length. The second wire stretchesi need steps
