Answer:
The answer to your question is: c = 353 mi/h; Ф = 7.3°
Explanation:
You can see the picture below
To solve this problem, just imagine a right rectangle which the legs is 350 mi/h and 45 mi/h and we are going to find the hypotenuse.
c² = a² + b²
c² = 350² + 45²
c² = 122500 + 2025
c² = 124525
c = 352.9 ≈ 353 mi/h
tanФ = 45/ 350
tan Ф = 0.12
Ф = 7.3°
Answer:
1.636 x 10^-5 m^3
Explanation:
As we know that
1 mol of copper = 63.5 g of copper
2.3 mol of copper = 63.5 x 2.3 = 146.05 g of copper = 0.146 kg of copper
Density of copper = 8.92 x 10^3 kg/m^3
The relation between mass and volume is given by
mass = volume x density
Thus, the volume of copper is 1.636 x 10^-5 m^3.
