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
Explanation:
the inability to change the position from rest to motion or motion to rest by themselves is inertia.
Answer:
Option A. 1 bar = 1 atm
Explanation:
Pressure has various units of measurement. Each unit of measurement can be converted to other units of measurement. For example:
1 atm = 1 bar
1 atm = 760 mmHg
1 atm = 760 torr
1 atm = 1×10⁵ N/m²
1 atm = 1×10⁵ Pa
With the above conversion scale we can convert from one unit to the other.
Considering the question given above, it is evident from the coversion scale illustrated above that only option A is correct.
Thus,
1 bar = 1 atm
