Answer:
Length of pipe organ(L) = 0647 m (Approx)
Explanation:
Given:
Temperature (T) = 14°C
Fundamental frequency (F) = 262 Hz
Speed of sound (v) = 331 + 0.60(T) m/s
Find:
Length of pipe organ(L)
Computation:
Speed of sound (v) = 331 + 0.60(14) m/s
Speed of sound (v) = 339.4
Length of pipe organ(L) = Speed of sound (v) / 2(Fundamental frequency)
Length of pipe organ(L) = 339.4 / 2 (262)
Length of pipe organ(L) = 0647 m (Approx)
Answer:
What evidence supports their claim.

Answer:
OptionD
The acceleration of the horse is 0.72m/s2
Explanation:
We can use the formula
we are looking for the acceleration, which is a. To find this, we can make a the subject of the formula as shown
Where a = acceleration of the horse
s = distance covered by the horse = 100m
v = final velocity of the horse = 12m/s
u = initial velocity of the horse = 0 m/s (this is because it starts from rest)
The acceleration of the horse is 0.72m/s2
