Answer:Divergent boundaries are areas where plates move away from each other, forming either mid-oceanic ridges or rift valleys. Tectonic plates can interact in one of three ways. They can move toward one another, or converge; move away from one another, or diverge; or slide past one another, a movement known as transform motion. All plate margins along which plate movement is occurring have one thing in common—earthquakes.
Answer:
Explanation:
101 dB = 10.1 B.
Maximum intensity of sound allowed = 10.1 B
Intensity of sound in terms of W/m² can be found as follows
log (I / I₀) = 10.1
I / I₀ = 10¹⁰°¹
I = I₀ X 10¹⁰°¹
= 10⁻¹² X 10¹⁰°¹
= 10⁻¹°⁹ W/m²
105 m above the ground the this intensity will be 105² times
intensity at source point = 10⁻¹°⁹ x 105²
= 138.79 W/m²
energy of sound from source
= 4π times
= 4 x 3.14 x 138.79
= 1743.28W/m²
To calculate in terms of decibel :
log 1743.28 / 10⁻¹²
= log 1743.28 +12
= 15.24 B
= 152.4 dB .
152.4 dB .
Answer:
The change is momentum is given by ∆p=p(inital) - p(final) =4-2=2 kg.m/s
Explanation:
momentum is the product of mass and velocity (speed)
So it's initial momentum would be:
p=mv=(1)(4)=4 kg.m/s
It's final momentum is given by:
p=mv=(1)(2)=2 kg.m/s
