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.
Because metric units use the deca system, 1km = 1000m = 100 000cm etc...
Answer:
6N
Explanation:
Force =mass x acceleration
Force = 2 x 3
Force = 6N
Q out = Q in
Q mix = Q water
mcΔt sand + mcΔt water = mcΔt water
30.2 x 2.01 x (29.3-12.1) + 87.7 x 4.19 x (29.3-12.1)=m x 4.19 x (85.8-29.3)
1044.07+6320.36=m x 236.74
m = 31.11 g
Answer:
a = (v₃₂ - v₂₁) / (t₃₂ -t₂₁)
Explanation:
This is an exercise of average speed, which is defined with the variation of the distance in the unit of time
v = (y₃ - y₂) / (t₃-t₂)
the midpoint of a magnitude is the sum of the magnitude between 2
t_mid = (t₂ + t₃) / 2
the same reasoning is used for the mean acceleration
a = (v_f - v₀) / (t_f - t₀)
in our case
a = (v₃₂ - v₂₁) / (t₃₂ -t₂₁)
