The heat required to raise the temperature of the unit mass of a given substance by a given amount (usually one degree).
Answer:
48.63 mL
Explanation:
Using Charles's law
Given ,
V₁ = 29 mL
V₂ = ?
T₁ = 25 °C
T₂ = 500 K
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (25 + 273.15) K = 298.15 K
Using above equation as:
<u>New volume = 48.63 mL</u>
It would be B. Because every angle has to add up to 180 degrees. 180-70 would give you 110
Answer: a. 667N
b. 665N
c. 54.5N
Explanation:
a) on the surface of the earth
W = mg
W = 68 × 9.81
= 667N
b) at the top of Everest (8848 m above sea level).
W =mg × R²/(R + H)²
W = 667 × [6378²/(6378 + 8.848)²
W = 665N
c) has 2 1/2 times the radius of the earth
W = mg × R²/(R + H)²
W = 667 × R²/(R + 2.5R)²
W = 54.5N
