One of the most dangerous side effects of an erupting volcano is a

Answer:

A. Constructive

B. Destructive

C. Destructive

D. Constructive

Explanation:

Constructive interference takes place at locations along the path of two superposed waves where the waves are in phase such that a high or low point of one of the waves corresponds with a high or low point of the other wave which gives a resulting wave amplitude which is the sum of the amplitudes of the individual waves

Destructive interference takes place at locations along the path of two superposed waves where one wave is out of phase with the other wave such that a high or low point of one of the waves coincides with a low or high point of the other wave respectively thereby cancelling the effect of the other wave and giving a resulting wave that has an amplitude which is the difference in the amplitudes of the individual waves

Therefore;

At point A, the peak of each wave partially coincides resulting in constructive interference

At point B, the peak of the blue wave and the trough of the red wave partially coincides resulting in destructive interference

At point C, the through of the blue wave and the peak of the back wave partially coincides resulting in destructive interference

At point D, the trough of each wave partially coincides resulting in constructive interference.

Answer:

Alcohol thermometers are used rather than mercury thermometers in very cold regions because alcohol has a lower freezing point than mercury. Pure ethanol freezes at -115 degrees C, while mercury freezes at -38 degrees C.

Explanation:

It is less durable because alcohol evaporates faster than mercury. It cannot measure high temperature because of a low boiling point. It wets the walls of the thermometer, which can adversely impact the accuracy of readings

Silicon Dioxide

Answer:

Silicon dioxide

Explanation:

The Sun creates energy through a series of steps known as nuclear fusion.

Nuclear fusion is the process by which atomic nuclei combine to form heavier nuclei, releasing a tremendous amount of energy in the process. In the Sun, this process occurs in the core, where the temperature and pressure are high enough to overcome the electrostatic repulsion between positively charged atomic nuclei. Hydrogen atoms are fused together to form helium atoms, releasing energy in the form of light and heat.

The process of nuclear fusion in the Sun can be broken down into several steps.

The first step involves the collision of two hydrogen atoms to form a deuterium atom, releasing a positron and a neutrino in the process. The deuterium atom can then combine with another hydrogen atom to form helium-3, releasing a gamma ray. Finally, two helium-3 atoms can combine to form helium-4, releasing two protons and releasing even more energy in the process.

Therefore, the process of nuclear fusion in the Sun is a complex series of steps that releases a tremendous amount of energy and is responsible for the light and heat that we receive on Earth.

Answer:

The wavelength is 1.7cm

Explanation:

Given

See attachment for wave pattern

Required

What is the wavelength

To do this, we simply calculate the distance between successive waves (see attachment 2 for point A and B)

Using the ruler, points A and B are at:

[tex]A = 0.6cm[/tex]

[tex]B = 2.3cm[/tex]

So, the wavelength is:

[tex]\lambda = B - A[/tex]

[tex]\lambda = 2.3cm - 0.6cm[/tex]

[tex]\lambda = 1.7cm[/tex]

If approximated, the wavelength is:

[tex]\lambda \approx 2cm[/tex]

Answer:

Explanation:

Although we do have an equation for this in terms of one-dimensional motion, it's easy enough just to use the mathematical definition of acceleration:

[tex]a=\frac{v_f-v_0}{t}[/tex]  which says, in words, the acceleration of an object is equal to the objects final velocity minus its initial velocity, divided by the change in time. Since everything is given in m and s, our answer will be in m/s/s:

[tex]a=\frac{16.0-4.0}{4.0}[/tex] and

[tex]a=\frac{12.0}{4.0}[/tex] so

a = 3.0 m/s/s
