You are going to use a balloon and rise in the corresponding altitudes. If the balloon weighs 1000kg (all included, weight of yourself, equipment, inflated part etc) calculate the volume of inflated part of the balloon, so that the initial acceleration is 15m/s?. Assume that the balloon is a sphere and neglect the deflated part of the balloon as far as volume is concerned. Can you verify all measurements with this volume of the balloon? What kind of adjustments do you need to make in order to complete your mission?What is the dew point (the temperature at which 100% relative humidity would occur) on a day when relative humidity is 39.0% at a temperature of 20.0oC ?
- The wind-chill index is modeled by the function W = 13.12 + 0.6215T – 11.37v0.16 + 0.3965TV0.16 where T is the temperature (°C) and v is the wind speed (km/h). When T = -19°C and v = 39 km/h, by how much would you expect the apparent temperature W to drop if the actual temperature decreases by 1°C? (Round your answers to two decimal places.) °C What if the wind speed increases by 1 km/h? ㅇCOn a certain day, the temperature is 25.0oC and the relative humidity is 90.0%. How many grams of water must condense out of each cubic meter of air if the temperature falls to 15.0oC? Such a drop in temperature can, thus, produce heavy dew or fog.Monica is a volleyball player. Results from her UWW give you these data: MA = 172 lb Height = 6 ft 1 in. RVA = 1.86 L Water temperature = 37.8 °C Tare weight = 2 kg MW = 5.32 kg Use those results to calculate her %BF.
