Q19. A hot air balloon is a type of aircraft. It is lifted by heating the air inside the balloon, usually with
fire. Hot air weighs less than the same volume of cold air (it is less dense), which means that hot
air will rise up or float when there is cold air around it, just like a bubble of air in a pot of water.
The greater the difference between the hot and the cold, the greater the difference in density, and
the stronger the balloon will pull up.
B
Lakshman is riding on a hot air balloon. After reaching at height at point P, he spots a lorry
parked at B on the ground at an angle of depression of 30°. The balloon rises further by 50 metres
at point and now he spots the same lorry at an angle of depression of 45° and a car parked at C
at an angle of depression of 30°.
6. What is the relation between the height z of the balloon at point P and distance between
point A and B?
(a) z=30
(b) d=31
(c) <=37
(d) 3 =>
(ii) When balloon rises further 50 metres, then what is the relation between new height and d?
Answers
the explanation is given in the images. I hope this helps all of you. In the end tho we can easily find QC as we have to find the distance between iiory and the car
Answer:
The bigger the temperature difference between the hot and cold, the greater the density differential, and the stronger the upward pull of the balloon. This implies that heavier loads can be carried by balloons on chilly days or when the air inside the balloon is extremely warm.
Step-by-step explanation:
What happens when the air in a hot air balloon is heated?
When the air within the balloon is heated, the air molecules start to migrate and spread out, which reduces the air's density. The heated air rises over the cooler, surrounding air. As a result, heated air is forced upward, lifting the balloon along with it.
Hot air rises above cold air because hot air has a larger density than cold air, which is why hot air balloons soar. Hot air fills a hot air balloon. The air that surrounds the hot air balloon is less thick when it is hot. In other words, hot air is lighter than cold air of the same volume. Thus, as a result of the cold air's buoyant effect, the balloon rises.
