Answer:
D. The objects particles move faster
Answer:
80Ω
Explanation:
Resistance in a series circuit (when one resistor is after another in the same line) is calculated with the following equation
Total resistance = R1 + R2 + R3...Rn
Substitute in your values and solve for total resistance
Total resistance = 60 + 20 = 80Ω
v = v₀ + at
v = final speed, v₀ = initial speed, a = acceleration, t = elapsed time
Given values:
v₀ = 0m/s (starts from rest), a = 9.81m/s², t = 3s
Plug in and solve for v:
v = 0 + 9.81(3)
v = 29.4m/s
A).
It would decrease because the speed of sound and temperature are proportional.
