In theory, pressure from the sun's radiation could propel a spacecraft outward away from the sun. For a spacecraft of mass = 1340 kg at the same distance from the sun as Earth (150 million km), how much area would a 100% reflecting "sail" need to have in order to balance the sun's force of gravity acting on the spacecraft? For reference, the sun's intensity just outside Earth's atmosphere is 1400 W/m² and the sun's mass is 1,99 x 1030 kg, and the universal gravitational constant G = 6.67 x 10-11 Nm²/kg². Convert your answer to square km (1 km² = 106 m²). A = km²

An electromagnetic wave with an amplitude of 8.00 V/m boils a cup of water in 4.00 minutes. (The units for the amplitude are here because we always need units, but they are not relevant to answering the question). If the amplitude was increased to 16.0 V/m, but everything else (e.g., frequency, distance of cup from source etc.) stayed the same, how long would it take to boil the same cup of water? Enter your answer in minutes.

During normal beating, a heart creates a maximum 3.85-mV potential across 0.285 m of a person’s chest, creating a 1.1-Hz electromagnetic wave. During normal beating of the heart, the maximum value of the oscillating potential difference across 0.285 m of a person’s chest is 3.85 mV. This oscillating potential difference produces a 1.1-Hz electromagnetic wave. What is the wavelength, in meters, of the electromagnetic wave?
