Answer:
350 m/s
31°C
Explanation:
Speed of sound is given as the product of frequency and wavelength
S=fw
Where s represent the speed in m/s, f is frequency and w is wavelength
Conversion
Taking 1m to be 100 cm then 35 cm will be 35/100=0.35m
Substituting 0.35 m for w and 1000 Hz for f then
S=1000*0.35=350 m/s
speed of sound (m/s) = 331.5 + 0.60 T(°C)
350=331.5+0.6T
T=30.833333333333
The temperature is approximately 31°C
Answer:
<h2>
6.36 cm</h2>
Explanation:
Using the formula to first get the image distance
1/f = 1/u+1/v
f = focal length of the lens
u = object distance
v = image distance
Given f = 16.0 cm, u = 24.8 cm
1/v = 1/16 - 1/24.8
1/v = 0.0625-0.04032
1/v = 0.02218
v = 1/0.02218
v = 45.09 cm
To get the image height, we will us the magnification formula.
Mag = v/u = Hi/H
Hi = image height = ?
H = object height = 3.50 cm
45.09/24.8 = Hi/3.50
Hi = (45.09*3.50)/24.8
Hi = 6.36 cm
The image height is 6.36 cm
