Answer:
1e - 11
Explanation:
C.
It helps compare wavelengths of light. This means it helps determine which side of the spectrum (visible or not).
V=20.2m3
P= 225.4kPa V= ? n= 1.85, T= 22.5+273= 295.5K, R = 8.314
Applying the ideal gas equation
PV=nRT
225.4×V = n×8.314×295.5
V= 20.2m3
A boulder sits at rest on top of a mountain. What conclusion can be made about the forces acting on the boulder? The forces acting on the boulder are balanced (net force equals zero).
