Answer:
13 m/s
Explanation:
Given:
Δy = 8.2 m
v₀ = 0 m/s
a = 9.8 m/s²
Find: v
v² = v₀² + 2aΔy
v² = (0 m/s)² + 2 (9.8 m/s²) (8.2 m)
v = 12.7 m/s
Rounded to two significant figures, the speed is 13 m/s.

The word that identifies the colour of an object seen under ordinary daylight is local colour.
The natural colour of the object, it is best seen on a matte surface because it is not being reflected and therefore distorted. It is the presentation of features of a particular locality.
Answer:
The fundamental frequency and length of the pipe are 100 Hz and 1.7 m.
Explanation:
Given that,
Frequency f = 550 Hz
Frequency f' = 650 Hz
We know that,
AMT pipe is open pipe.
(b). We need to calculate the length of the pipe
Using formula of organ pipe
For 550 Hz,
...(I)
For 650 Hz,
...(II)
From equation (I) and (II)
(a). We need to calculate the fundamental frequency for n = 1
Using formula of fundamental frequency
put the value of L
Hence, The fundamental frequency and length of the pipe are 100 Hz and 1.7 m.
