Answer:
Explanation: Bulk Modulus (K) =
This is the same as saying it equal to the change in pressure with respect to the change in volume divided by initial volume.
Bulk modulus elasticity may also be expressed in terms of pressure and density:
<em><u>Remember:</u></em> <em>Strain is a unit-less quantity.</em>
Here,
- ρ0 and ρ1 are the initial and final density values.
- p₀ & p₁ are the initial and final pressure values.
<u>Given data:</u>
bulk modulus,
volumetric strain,
<u>To find:</u> Force exerted by the juice per square centimeter,
Solution:
⇒
A force that acts on rock to change its shape or volume (the amount of space a rock takes up) is stress. Stress adds energy to the rock. The energy is stored in the rock until it changes shape or breaks. Three different kinds of stress can occur in the crust—tension, compression, and shearing.
Answer:
(1) The orbits are ellipses, with focal points ƒ1 and ƒ2 for the first planet and ƒ1 and ƒ3 for the second planet. The Sun is placed in focal point ƒ1.
(2) The two shaded sectors A1 and A2 have the same surface area and the time for planet 1 to cover segment A1 is equal to the time to cover segment A2.
(3) The total orbit times for planet 1 and planet 2 have a ratio a13/2 : a23/2
Answer: The electron moves slower than the speed of light
Explanation:
The de Broglie wavelength is given by the following formula:
(1)
Where:
is the Planck constant
is the momentum of the atom, which is given by:
(2)
Where:
is the mass of the electron
is the velocity of the electron (the value we want to find)
Substituting (2) in (1):
(3)
Finding :
(4)
(5)
Finally:
>>> This is the velocity of the electron, which compared to the of the light is quite slower.

Answer:
The expression for the change in the air temperature is
Explanation:
From the question we are told that
The mass of the train is M
The speed of the train is v
The volume of the station is V
The density of air in the station is
The specific heat of air is
The workdone by the break can be mathematically represented as
Now this is equivalent to the heat transferred to air in the station
Now the heat capacity of the air in the station is mathematically represented as
Now Since this is equivalent to the workdone by the breaks we have that
=>
