Answer:
The answer to your question is: Cp = 350.4 J/ kg°C
Explanation:
Data
mass = m = 4.7 g convert grams to kilograms 0.0047 kg
heat= Q = 52.7 J
Temperature = 25 - 57 °C
Formula
Q = mCpΔT solve for Cp
Cp = Q / mΔT
Process
Cp = 52.7 / [(0.0047)(57 - 25)] Substitution
Cp = 52.7 / 0.1504
Cp = 350.4 J/ kg°C
The osmium with a density of 22.6g/cm3 has a volume in cm3 of 0.965 cm3
The density formula and the procedure we will use is:
ρ = m/v
Where:
- v= volume
- ρ= density
- m= mass
Information about the problem:
Applying the density formula and isolating the volume (v), we get:
ρ = m/v
v = m / ρ
v = 21.8 g / 22.6g/cm3
v = 0.965 cm3
<h3>What is density?</h3>
It is a physical quantity that expresses the ratio of the body mass to the volume it occupies.

<u>Answer:</u> The correct answer is 0.745 km
<u>Explanation:</u>
We are given:
A numerical value of 815 yards
To convert this into kilometers, we use the conversion factor:
1 km = 1093.6 yards
Converting the given value into kilometers, we get:
![\Rightarrow 815yd\times \frac{1km}{1093.6yd}=0.745km](https://tex.z-dn.net/?f=%5CRightarrow%20815yd%5Ctimes%20%5Cfrac%7B1km%7D%7B1093.6yd%7D%3D0.745km)
Hence, the correct answer is 0.745 km
