First-order analysis of a seismogram record allows seismologists to do all but which of the following?

The distance between the wall of the cavity is 7.5 cm

Distance is the length of a space between two points at rest or in motion.

Since the waves are travelling within two parallel, highly conducting walls, i.e. both the ends are rigid and closed, the general formula for the distance (L) between both closed ends is (n+1) λ/2

for n = 0, λ/2 = 1.5 cm

λ = 3.0 cm

for λ(n+1/2) = 1.25

λ(n+1) = 2.5

(n + 1) * 1.5 = (n + 2) * 1.25

n = 4

L = (n+1) λ/2

L  = (4+1) 3/2

L = (5) * 3 / 2

L = 7.5 cm

The distance L between the walls of the cavity is 7.5 cm.

The complete question is-

10 of 10 An ammonia refrigeration cycle involves the conversion of 1.41 kg of liquid ammonia into vapor every minute at the boiling-point temperature. At what rate does the ammonia absorb energy?

The gas has undergone work of 567.42 J, and the internal energy has changed by 167.42 J.

It is the summation of all the potential and kinetic energy of the atoms and molecules that make up the material that is represented in the system.

Briefing:

As given in the problem a gas is compressed at a constant pressure of 0.800atm from 9.00 L to 2.00 L. In the process, 400 J of energy leaves the gas by heat.

1 atm = 101325.00 N/m²

0.800 atm = 0.800×101325.00

                 =81060 N/m²

The work done by the gas under constant pressure

W = P×( V₂ -V₁)

   =81060×(2- 9)×10⁻³

  = - 567.42 J

A negative sign represents that work is done on the gas

By using the first law of the thermodynamics

ΔQ = ΔU +W

-400 = ΔU - 567.42

ΔU = 167.42 J

Thus, The work done on the gas is 567.42 J and the change in the internal energy would be  167.42 J

The speed of the runners after the inelastic collision is 0.96 m/s towards the south.

The final speed of the runners after the collision is calculated by applying the principle of conservation of linear momentum as follows;

m₁u₁ + m₂u₂ = v(m₁ + m₂)

where;

110 (8) + 130(-5) = v (110 + 130 )

880 - 650 = 240v

230 = 240 v

v = 230 / 240

v = 0.96 m/s

When two items come into close proximity, thermal energy moves from the warmer object (which has faster-moving particles) to the colder object (with slower-moving particles).

First, heat is transferred from the lower-temperature object to the higher-temperature object, then it is transferred back to the lower-temperature object, and so on, until the objects are in thermal equilibrium.

Thermal radiations have a frequency range in the infrared and are electromagnetic in nature. All bodies that have an absolute temperature that is not zero emit these. Since they are electromagnetic, heat radiations can bounce off of them and move through space at the speed of light. All of the statements are true.

Some factors that might determine how hot a wire will get when it conducts electricity is Current, Material and Ambient temperature.

Resistance of the wire: The resistance of a wire determines how easily electricity can flow through it. Wires with higher resistance will tend to get hotter when conducting electricity because they resist the flow of current more than wires with lower resistance.

Current: The amount of current flowing through the wire can also affect how hot it gets. Higher current means more electrons are flowing through the wire, which can cause it to heat up more.

Length and diameter of the wire: The length and diameter of the wire can also affect how hot it gets. Longer wires or wires with a larger diameter will tend to have lower resistance, which means they will conduct electricity more easily and may not get as hot as shorter or thinner wires.

Material: The material of the wire can also play a role in how hot it gets. Different materials have different electrical conductivity and resistance properties, which can affect how hot the wire gets when conducting electricity.

Ambient temperature: The ambient temperature of the environment in which the wire is located can also influence how hot it gets. If the ambient temperature is higher, the wire may heat up more quickly due to increased thermal energy.
