A. An indirect measure of heat energy
Answer:
μ = 0.6
Explanation:
F = μN
N = mg
F = μmg
3 N = μ*0.5 kg * 9.8 m/s²
μ = 3/(0.5*9.8) = 0.6
Answer:
... As has been previously discussed, heat is not something that is contained in an object.
Explanation:
The displacement of Edward in the westerly direction is determined as 338.32 km.
<h3>What is displacement of Edward?</h3>
The displacement of Edward can be determined from different methods of vector addition. The method applied here is triangular method.
The angle between the 200 km north west and 150 km west = 60 + 90 = 150⁰
The displacement is the side of the triangle facing 150⁰ = R
R² = a² + b² - 2abcosR
R² = 150² + 200² - (2x 150 x 200)xcos(150)
R² = 62,500 - (-51,961.52)
R² = 114,461.52
R = 338.32 km
