F has direct relation with a
then doubling F cause acc. to get double i:e 6×2=12
Mass= volume x density
Mass= 90kg/m^3 x 2.3m^3
Therefore, Mass= 207 kg
You may have a cold if you do not feel well, depends on the symptoms
Answer:
342 m/s
Explanation:
The velocity of sound in air is approximated as:
v ≈ 331.4 + 0.6 T
where v is the velocity in m/s and T is the temperature in Celsius.
At T = 18:
v ≈ 331.4 + 0.6 (18)
v ≈ 342.2
The velocity is approximately 342 m/s.
Answer:
light doesn't need a medium through which to travel because the speed of light is experimentally constant
