Determine the specific heat of iron if 6.1 j of energy are needed to warm 1.50 g of iron from 20.0◦c to 29.0◦c?

1 answer:

As the iron core isprogressively laid down, the mechanism of iron oxidation changes from a protein dominated process with H202 being the primary product of O2 reduction to a mineral surface dominated process where H20 is the primary product. These results emphasize the importance of the apoferritin shell in facilitating iron oxidation in the early stage of iron deposition prior to significant development of the polynuclear iron core.

Bogdan [553]

Answer:

the phase difference is 1.26 radian

Solution:

As per the question:

Distance, d = 2 m

Distance from the other speaker, d' = 2.1 m

Frequency, f = 680 Hz

Speed of sound, v = 340 m/s

Now,

To calculate the phase difference, $\Delta \phi$ :

Path difference, $\Delta d = d' - d = 2.1 - 2 = 0.1\ m$

For the wavelength:

$f\lambda = v$

where

c = speed of light in vacuum

$\lambda$ = wavelength

Now,

$680\times \lambda = 340$

$\lambda = 0.5\ m$

Now,

Phase difference, $\Delta phi = 2\pi \frac{\Delta d}{\lambda}$

$\Delta phi = 2\pi \frac{0.1}{0.5} = 1.26\ rad$

A scientist prepares a colloidal solution and pours it into a glass tank. She then flashes a beam of white light into one end of

irina [24]

Light is consist of different spectrum of colors called wave lengths. The colors that visible to the naked eye are known as Red, Orange, Yellow, Green, Blue, Indigo, and Violet. These colors are arranged from shortest to longest. The color red that appeared from the other side of the tank signifies that the wavelength that can only pass through the material is red, which is the shortest. Other wavelengths are dispersed into the molecules of the glass, hence it cannot be seen through the other side.

If your vehicle has a steering wheel lock, should you ever turn off the ignition while it is moving?

umka2103 [35]

It is not advisable to turn off the ignition while it is moving, so it is a no. Why? Even though the vehicle has steering wheel lock, turning off the ignition while it is moving is not advisable because it causes the vehicle to lose out of control, leading to complications and accidents.
