There are 2.1077x10^24 atoms of sulfur in 3.50 mols of sulfur.
Answer:
8.0 rad/s
Explanation:
I₁ = 1.0 kgm², ω₁ = -20.0 rad/s (clockwise is positive direction)
I₂ = 4.0 kgm², ω₂ = 15.0 rad/s
Angular momentum conservation:
I₁ω₁ + I₂ω₂ = (I₁ + I₂)ω
1.0 x (-20.0) + 4.0 * 15.0 = (1.0 + 4.0)ω
40.0 = 5.0ω
so ω = 8.0 rad/s
Answer:
Angle will be
Explanation:
We have given frequency of the sound f = 600 Hz
Vertical opening is of 0.8 meter
So width D = 0.8 m
Velocity of sound v = 340 m/sec
We know that wavelength
Now for the first minimum
35 m is equivalent to 0.035 kilometers
