Wavelength decreases as frequency increases.
Taylor Swift was observing the amplitude of the waves as compared to the day before.

Answer from: helpmeplz11239

For 1: The correct answer is Wavelength.

For 2: The correct answer is Amplitude.

Explanation:

Wavelength is defined as the distance between two crests or two troughs.

Frequency is defined as the number of oscillations that occur in 1 second.

Amplitude is defined as the maximum displacement from its equilibrium position. It is the vertical distance from the crest to the equilibrium position of the wave.

Intensity of the wave is basically the energy of the wave and it is proportional to the square of the amplitude of the wave.

Speed of the wave the is defined as the distance traveled by a given point on a wave.

For 1:

As, the number of crests increases on a point which means that the number of oscillations increases and hence, the frequency increases.

Frequency is inversely proportional to the wavelength of the wave and therefore, increase in frequency will result in the decrease of wavelength.

Hence, the correct answer is Wavelength.

For 2:

When Taylor Swift stood knee deep in the ocean, she noticed that the waves were high as compared to the previous day, which means that the vertical distance of the wave has increased from its mean position.

Hence, the correct answer is Amplitude.

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.

Modern pennies are composed of zinc coated with copper. a student determines the mass of a penny to be 2.482 g and then makes several scratches in the copper coaling (to expose the underlying zinc). the student puts the scratched penny in hydrochloric acid, where the following reaction occurs between the zinc and the hcl (the copper remains undissolved): zn(s) + 2 hcl(aq) → h2(g) + zncl(aq)the student collects the hydrogen produced over water at 25 °c. the collected gas occupies a volume of 0.899 l at a total pressure of 79 j mmhg. calculate the percent zinc (by mass) in the penny. (assume that all the zn in the penny dissolves.)
