Answer:
C: Variation in the value of g as the pendulum bob moves along its arc.
Explanation:
The formula for period of a simple pendulum is given by;
T = 2π√(L/g)
Where;
L is length
g is acceleration due to gravity
Now, from this period equation, it is clear that the only thing that can affect the period of a simple pendulum are changes to its length and acceleration due to gravity.
Looking at the options, the only one that talks about either the length or gravity as being potential causes of the error is option C
Of approximately 1 to 4 kHz6 and approximately 16 kHz for mice.
Answer:
Explanation:
a = Δv/Δt = (v₁ - v₀) / (t₁ - t₀)
A a = (10 - 0) / (5 - 0) = 2 m/s²
B a = (10 - 10) / (15 - 5) = 0 m/s²
C a = (5 - 10) / (25 - 15) = - 0.5 m/s²
