When a steel cookie sheet is placed in an oven and heated, it expands due to
the temperature change. The change in area of the cookie sheet is modeled
using the following equation:
∆A=Ao γ ∆T
where ΔΑ = change in area in in2, A0 = original area in in2 γ = area coefficient
of thermal expansion, ΔΤ = change in temperature in F°, What is the
appropriate unit for γ if the preceding equation is to be homogeneous in units?
- correct answer ✔1/oF
, The force between two charged particles can be calculated using the following
equation:
F=k (q1 q2)/r^2
Where F = force in Newtons G = electrostatic constant q1 = charge of particle
#1 in Coulombs, q2 = charge of particle #2 in Coulombs, r = distance between
particles in meters? - correct answer ✔N m^2/C^2
The acceleration due to gravity at or near the surface of the moon is
