<span>Our equation 1 would be
m*v=M*V1+m*V2
v=V1+V2
v-V1=V2
the equation 2 would look like this
</span>V^2=V1^2+V2^2
V^2-V1^2=V2^2
(V-V1)*(V+V1)=V2^2Dividing with the 1
V+V1=V2
There diffrent but can cause the same thing
Answer:
A. Particles in air move in circles as the wave moves forward.
B. Particles in air move forward but not backward as the wave moves
forward.
C. Particles in air move up and down as the wave moves forward.
✔ D. Particles in air move forward and backward as the wave moves
forward.
Explanation:
The waves transfer energy from the source of the sound, e.g. a drum, to its surroundings. Your ear detects sound waves when vibrating air particles cause your ear drum to vibrate. The bigger the vibrations the louder the sound.
<h2>The pressure will become double </h2>
Explanation:
The gas pressure is directly proportional to the mean root square velocity of the constituent molecules of gas .
P ∝ 
I
Here C₁ , C₂ ------------ Cₙ is the velocities of molecules .
By making these velocities double
The pressure P₀ ∝ 2 II
By dividing II by I
P₀ = 2 P
Thus pressure will become double than its previous value
Answer:
80,886 cm^3
Explanation:
v= lwh (also known as length × width × height)
v = 122cm × 51cm × 13cm
v = 80,886 cm^3
