The correct answer is C. A scientific inquiry is the process of gathering evidences, using the natural world. Using these evidences, the explanations are proposed. A sceintific inquiry leads to the develoment of hypthesis, which explains a particular process by a set of observations.
Answer:
C=F×W
so, W=C/F
Explanation:
frequency=F
wavelength=W
speed of light =C in that medium
Answer:
Time taken by Jesse to bring his bicycle =5.4 Sec
Explanation:
acceleration of bicycle = -2.5 m/sec²
Initial velocity of by cycle u =13.5 m/sec,
final velocity of bicycle v = 0 (since bicycle completely stop finally)
Let the time taken to stop the bicycle completely = t sec
We now by equation of motion,
putting the value of u,v & a in the equation
0=13.5 -2.5 x t ( a is taken as negative since velocity of bicycle is reducing)
= 5.4 Sec
The effective length of the tube is responsible for determining the frequency of vibration of the air column in the tube within a wind instrument.
