How hot is the air in the top (crown) of a hot air balloon? Information from Ballooning: The Complete Guide to Riding the Winds, by Wirth and Young (Random House), claims that the air in the crown should be an average of 100°C for a balloon to be in a state of equilibrium. However, the temperature does not need to be exactly 100°C. What is a reasonable and safe range of temperatures? This range may vary with the size and...
Question 5 (25 marks) a) A hot air balloon is hovering 800m directly above a lake. The balloon is observed by the crew of a boat as they look upwards at an angle of 20. Four minutes later, the crew has to look at an angle of 65° to see the hot air balloon. How fast was the boat traveling in meters per minute? b) Given the triangle ABC, IABI 15, IACI 12 and BAC 60°. Find IBCI. (6) c)...

summarizr the followung info and write them in your own words and break them into different key points. 6.5 Metering Chamber: 6.5.1 The minimum size of the metering box is governed by the metering area required to obtain a representative test area for the specimen (see 7.2) and for maintenance of reasonable test accuracy. For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...
