Answer:
The correct phrase is: The recorded boiling point will be higher than actual because hotter vapors travel higher up the condenser
Explanation:
When we have a system that is going from the liquid phase to the vapor phase, there is an energy that is spent for this change of state. Therefore the temperature of the liquid remains constant until it has changed state, but the steam that comes out can continue to heat up, so it has a temperature more wing than the liquid.
If the thermometer is very high it will measure the temperature of the vapors, as the temperature is a form of energy these hotter vapors will rise more in the condenser tube.
The correct phrase is: The recorded boiling point will be higher than actual because hotter vapors travel higher up the condenser
Given the relationship: v = wavelength times frequency
this should be as simple as multiplying it out :)
for any other variable just rearrange
velocity = lambda x frequency
where lambda is the wavelength
units:
m/s = m x Hz (1/s)
Answer:
0.99Hz
Explanation:
Using F= -mx ( spring force)
At equilibrium the gravitational force will be balanced by the spring force so mg= kx
K= mg/ 0.25 N/m
But
Frequency f= 1/2pi √g/0.25
Frequency is 0.99Hz
