Answer:
a) If the thermometer is placed well below the condenser it will record a higher temperature.
b) If the thermometer is placed well above the condenser it will record a lower temperature.
Explanation:
A) ) If the thermometer is placed below the opening to the condenser, a higher temperature will be recorded than if it is placed close to the opening since the bulb is contact with both the vapuor and liquid that is entering the condenser.
B) If the thermometer is placed above the condenser, a lower temperature will be recorded than if it is placed close to the opening since the bulb is not in full contact with both the vapuor and liquid that is entering the condenser.
Answer:
34.45m
Explanation:
Using the equation of motion formula v² = u²+2as to get the distance travelled
v is the final velocity = 26m/s
u is the initial velocity = 0m/s
a is the acceleration due to gravity = 9.81m/s²
S is the distance travelled
Substituting the given values into the formula;
26² = 0²+2(9.81)s
676 = 0 + 19.62s
19.62s = 676
s = 676/19.62
s = 34.45m
Hence the distance she would travel during the race is 34.45m
Answer:
16
Explanation:
The atomic mass of an element is defined as the average of the isotopic masses, weighted according to the naturally occurring abundances of the isotopes of the element. Although oxygen has nine isotopes with mass numbers ranging from 13 to 21, oxygen-13, oxygen-14 and oxygen-15 are not naturally occurring isotopes. So, we do not need to include them when we calculate the relative atomic mass of oxygen.
Answer: Pitch
Explanation:
Pitch of sound is defined as the factor that monitors the sound quality through produced vibrations rate.It helps in determination of sounds tone in terms highness or lowness.
According to the question,Enrico is finding difficulty in judging the difference between pitch sound of tuba and piccolo as per their tone in terms of high or low.
