Answer:
(a) Tension=28.28 N
(b) Speed=29.14 m/s
Explanation:
Given data
f(frequency)=875 vibration/second
λ(wave length)=3.33 cm=0.0333 m
m(mass)=16.3 g=0.0163 kg
To find
(a) Tension
(b) Speed
Solution
For (b) at what speed the wave travel
For (a) Tension
So screw must adjust such that tension in the wire is 28.28 N
Answer:
8.96 g/
Explanation:
Volume of cylinder = base area (height)
= π()(4.970)
= 6.3356
Density of cylinder =
=
= <u>8.96 g/</u><u></u>
The quantity of heat must be removed is 1600 cal or 1,6 kcal.
<h3>Explanation : </h3>
From the question we will know if the condition of ice is at the latent point. So, the heat level not affect the temperature, but it can change the object existence. So, for the formula we can use.
If :
- Q = heat of latent (cal or J )
- m = mass of the thing (g or kg)
- L = latent coefficient (cal/g or J/kg)
<h3>Steps : </h3>
If :
- m = mass of water = 20 g => its easier if we use kal/g°C
- L = latent coefficient = 80 cal/g
Q = ... ?
Answer :
So, the quantity of heat must be removed is 1600 cal or 1,6 kcal.

Explanation:
Seismic refraction is the bending of the seismic waves as they pass geological layers of the earth due to different densities. This is especially true for Primary waves because they can pass through all the layers of the earth both liquid and solid.
Seismic reflectivity is the bouncing back of seismic waves at a boundary of geological layers due to different densities or subsurface formation. This is especially true for secondary waves that are unable to pass through liquid layers of the earth like the outer core and mantle. When they reach the boundary of these layers they bounce back towards the earth's surface.
These properties of P and S waves are used to ‘auscultate’ the epicenter of an earthquake by triangulation.
