D. Convection heat transfer is<span> caused within a fluid by the tendency of getting hotter and that causes less dense material to rise and colder material to sink caused by gravity, which results in convection heat transfer. Hope this helps </span>
The first one, the third one, and the last one :)
Could you show the question? or are there options? like a, b, c, or d
Answer:
The bee travelled a total distance of 11.7 metres, in order to collect pollen from a flower and then back to its hive.
Note: The question is not clearly stated. A similar but clearly stated question is given below:
A bee flew 840 cm and landed on a flower to collect some pollen. Then the bee flew another 330 cm to get back to her hive. How many meters did the bee travel?
Explanation:
Th distance travelled by the bee is the sum total of all the ground covered by the bee.
The initial distance travelled by the bee to get to the flower = 840 cm
After collecting pollen from the flower, the distance travelled by the bee to get to its hive = 330 cm
The total distance travelled by the bee = 840 cm + 330 cm = 1170 cm
The distance covered in centimetres is then covered to metres
100 centimetres = 1 metre
Therefore, 1170 cm = 1170 cm × 1 m /100 cm = 11.7 m
Therefore, the bee travelled a total distance of 11.7 metres, in order to collect pollen from a flower and then back to its hive.
