Answer:
354 m/s
Explanation:
For the second overtune (Third harmonic) of an open pipe,
λ = 2L/3................................ Equation 1
Where L = Length of the open pipe, λ = Wave length.
Given: L = 1.75 m.
Substitute into equation 1
λ = 2(1.75)/3
λ = 1.17 m.
From the question,
V = λf.......................... Equation 2
V = speed of sound in the room, f = frequency
Given: f = 303 Hz.
Substitute into equation 2
V = 1.17(303)
V = 353.5
V ≈ 354 m/s
Hence the right answer is 354 m/s
Answer:
The speed is equals to 22.49 m/s
Explanation:
Given Data:
Required:
Speed of Traverse wave = c =?
Solution:
As we know that
Now the equation for speed of traverse wave is calculated through:
=
Substituting the values
=22.49 m/s
Answer:
Explanation:
mass of baseball, m = 0.148 kg
initial velocity, u = 15.5 m/s
final velocity, v = 10.1 m/s
Impulse is defined as the change in momentum of the body.
Impulse = change in momentum
I = m (v - u)
I = 0.148 (10.1 - 15.5)
I = - 0.8 Ns
Answer:
It's D
Explanation:
Sorry if im wrong, correct me in comments and tell them actual answer if I'm wrong.
Answer:
Explanation:
As we know that mass is the product of volume and density
so we will have
here we have
so we will have
so we will have
now let the position of Pluto is at origin so we have
