Answer:
69×10⁻³ m
Explanation:
The linear thermal expansion coefficient for water is α = 69×10⁻⁶ K⁻¹.
Thermal expansion equation:
α ΔT = ΔL / L
Given ΔT = 1.00ºC = 1.00 K and L = 1.00 km = 1.00×10³ m:
(69×10⁻⁶ K⁻¹) (1.00 K) = ΔL / (1.00×10³ m)
ΔL = 0.069 m
ΔL = 69×10⁻³ m
Answer:
the mass is the same
Explanation:
the mass of electrons is negligible so losing some to become positively charged causes no change in mass
Answer:
The measurement which is the most precise is 104.6 °C.
Explanation:
The measurement which is most precise must be very close to the actual value of the temperature.
Thus, the unit which have less value of the |Δx| (error) must be most precise.
Thus,
Actual value = 105.1 °C
Value = 103.7 °C
<u>|Δx| = 1.4 °C</u>
Value = 108.4 °C
<u>|Δx| = 3.3 °C</u>
Value = 105.8 °C
<u>|Δx| = 0.7 °C</u>
Value = 104.6 °C
<u>|Δx| = 0.5 °C</u>
<u>Thus, The measurement which is the most precise is 104.6 °C.</u>
I do not understand what your saying could u plz be more specific?
