A quartz crystal vibrates with a frequency of 93621 Hz. What is the period of the crystals motion? T=1/93621 does not give me the correct answer. I got 0.00001?

Answers

The time period of the crystal motion is equal to 1.06 ×10⁻⁵ seconds.

How is a time period related to frequency?

The time period of oscillation of a wave can be defined as the time taken by any element to complete one oscillation.

The time period for a wave can be represented as follows:

T = 2π/ω

The frequency defines as the number of completeoscillations made by any wave element per unit of time. The frequency can be defined as a parameter that explains the rate of oscillation and vibration.

The relation between the frequency and the time period can be written as:

f = 1/T

Where f is the frequency of the wave and T is the time period of the wave.

Given, the frequency with which the crystalvibrates, f = 93621 Hz

The time period (T) of the crystals motion can be determined as:

T = 1/f = 1/ 93621

T = 1.06 ×10⁻⁵ sec

Which of the following phases changes at point B on the diagram shown below? A)deposition
B)freezing
C)melting
D)boiling

Answers

At point B, the substance undergoes deposition, transitioning directly from a gas phase to a solid phase. The correct option is a.

At point B on the phase diagram, the phase transition occurring is deposition. Deposition is a physical process in which a substance transitions directly from a gas phase to a solid phase without passing through the liquid phase. This change is driven by a decrease in temperature or an increase in pressure.

During deposition, gas particles lose energy, causing them to slow down and come together to form a solid structure. This process is exemplified in nature when water vapor in the atmosphere turns directly into frost or ice crystals on a cold surface. Deposition is the opposite of sublimation, where a substance transitions from a solid to a gas without becoming a liquid.

Earth surface are composed of 70% of water and 30% of lands or soil.Therefore, whatever happens to our earth surface results to global warming.
Trees, waters and other natures protect our mother earth from direct heat of ultraviolet rays of sunlight, when these are gone, it will result to too much heat and even damage to our environment.
