Answer:
B) 89500 km
Explanation:
speed = distance / time
time= 3h 58 min = 30+58/60= 30.966 h = 31 hrs (approxx)
250= distance / 31
250× 31= distance
distance = 7750 ( approxx)
but none of the given options is 7750 km so we will choose the answer nearest to it,
therefore 89500km is the right answer
Answer:
b a model of water temperatures in the oceans
Explanation:
A conceptual model is a means of representing abstract theories, with the aim of helping the audience form mental pictures about the subject being discussed. Most of these models utilize diagrams to help form a better understanding of the subject.
In geothermal explorations, water temperatures can be represented using plane or cross sectional views to demonstrate the varying temperatures of water. This is a useful guidde in the exploration proceess and helps any who read the illustrations to form a better understanding of the process and conditions.
Answer:
triple covalent bond
Explanation:
A triple covalent bond is formed when three pairs of electrons (six electrons) are shared between the two combining atoms. A triple bond is shown by marking three short lines between the two symbols of the atoms. It requires three more electrons to attain the stable octet.

Answer:
destroy
Explanation:
cuz if anyhow throw rubbish, it will affect/destroy the world environment
0.050 M Urea, 0.10 M glucose, 0.20 M sucrose and pure water.
<u>Explanation:</u>
Vapor pressure is the measure of pressure existing above the surface of the solution. Depending upon the vapor pressure of solutions, the boiling points will differ. In other words, decrease in vapor pressure leads to increase in the boiling point.
Since, the number of molecules present above the surface of the solution leads to easy evaporation of those molecules. But if the number of molecules on the surface or vapor pressure on the surface will be less, the boiling point will increase.
Thus, 0.050 M urea has the highest vapor pressure indicating that it can be easily evaporated, then 0.10 M of glucose has the vapor pressure followed by 0.20 M sucrose. Finally, the vapor pressure of water is the lowest and it will have the boiling point of 100 degree celsius.
