Pressure (P) is the amount of force applied perpendicular to the surface of an object per unit area. The SI unit of pressure is the pascal (Pa), which is equivalent to N/ $m^{2}$ (newtons per meter squared).

A 0.335 kg mass is attached to a spring and executes simple harmonic motion with a period of 0.38 s. The total energy of the sys

kramer

Answer:

$k=91.54 \frac{N}{m}$

Explanation:

The angular speed is defined as the angle traveled in one revolution over the time taken to travel it, that is, the period. Therefore, it is given by:

$\omega=\frac{2\pi}{T}\\\omega=\frac{2\pi}{0.38s}\\\omega=16.53\frac{rad}{s}$

The angular frequency of the simple harmonic motion of the mass-spring system is defined as follows:

$\omega=\sqrt{\frac{k}{m}}$

Here, k is the spring's constant and m is the mass of the body attached to the spring. Solving for k:

$\omega^2=\frac{k}{m}\\k=m\omega^2\\k=0.335kg(16.53\frac{rad}{s})^2\\k=91.54 \frac{N}{m}$

What conclusion could you make about conduction and convection based on these observations?

schepotkina [342]

C) No valid conclusion is suggested by these observations.

Explanation:

From the experiment, no valid conclusion can be drawn from the observations.

The tests are simply based on heat loss by a material.

In conduction, heat is lost by contact between materials in which heat flows from one to another.
Convection is a form of heat loss in which heat flows by density in fluids
The test carried out does not provide proof and comparison between heat loss by conduction and convection.
