Water cycle, evaporation, condensation, and freezing
Answer:
eardrum is the correct answer
hope this helps ❤️
Explanation:
Sound waves enter the ear canal and cause the eardrum to vibrate. Three small bones transmit these vibrations to the cochlea. This produces electrical signals which pass through the auditory nerve to the brain, where they are interpreted as sound.
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.
Answer:
The magnitude of the electrostatic force is
Explanation:
Given that,
Charge
Charge
Distance = 2.40 m
We need to calculate the electrostatic force
Using formula of electrostatic force
Where, k = coulomb's constant
q = magnitude of the charge
d = distance
Put the value into the formula
Hence, The magnitude of the electrostatic force is
B.changing speed
Explanation:
because if it keeps changing directions and turning it's going to slow down and then speed up.
