A company selling a type of spring makes the following claim: “The elastic potential energy that the spring is capable of storin

To address this problem, Boyle's Law must be applied, which states that the initial and final pressures and volumes are related as follows: Where, P₀ and V₀ represent the initial pressure and volume, while P and V refer to the final pressure and volume. The endpoint pressure in this scenario is atmospheric pressure. Thus, using the given equation, we can find the volume the lungs would occupy at the surface.

Answer:

The energy unit is expressed as kg-m/s or Joules.

Explanation:

The relationship between mass and energy in physics is represented by:

Where

m denotes the mass of the object

c signifies the speed of light

In the SI system, mass is measured in kilograms and the speed of light in m/s. Therefore, energy is defined in kg-m/s, which is equal to Joules.

Thus, the appropriate SI unit for energy is kg-m/s or Joules. This concludes the explanation.

Answer:

Explanation:

The overall energy expenditure of the salmon, which corresponds to its swimming upstream effort, , is linked to its specific mechanical power. calculated per unit mass can be derived from the following equation:

As a result, the total energy utilized during the 22-day journey is 7.603 MJ

<span>E = h x f </span>

<span>Thus: </span>

<span>f = E / h </span>
<span>f = 4.41•10^-19 / 6.62•10^-34 </span>
<span>f = 6.66•10^14 Hz (s^-1) </span>


<span>b/ What is the wavelength of this light? </span>
<span>------------------------------ </span>

<span>λ = c / f </span>
<span>λ = 3•10^8 / 6.66•10^14 </span>
<span>λ = 4.50•10^-7 m </span>

Answer:

Arrangement A facilitates a greater rate of heat transfer

Explanation:

The rate of heat conduction between two materials differing in temperature adheres to the formula

This equation demonstrates that

• An enlarged equivalent cross-sectional area between the two materials will enhance the rate of heat transfer.
• A reduction in the length of the medium will also amplify the rate of heat transfer

Arrangement A features a shorter transfer medium and a larger equivalent cross-sectional area, since the two rods are set up in a parallel arrangement.

Conversely, Arrangement B has a longer transfer medium and a smaller cross-sectional area, as the two rods are placed end to end
