Why might a major volcanic eruption lead to cooler global temperatures? Explain your answer.

Physics
1 answer:
irina [24]2 years ago
4 0

Answer:

Volcanic eruptions cool down  the planet

Explanation:

Volcanic eruptions actually cool the planet because the particles ejected from volcanoes shade incoming solar radiation. ... The small ash and aerosol particles decrease the amount of sunlight reaching the surface of the Earth and lower average global temperatures.

Hope this helps!!! :D

Help!! I’ll give brainliest! Match the changes in sound wave properties with their effects on an observer.

The answers are:
A:1
B:2
C:3

In short, they are already arranged. 

<em>Pitch </em><em />is defined as the sensation of a frequency. A high frequency corresponds to a high pitch. Low frequency corresponds to low pitch. So it is right to assume that rising frequency will cause a rising pitch. 

<em>Amplitude </em> is defined by the loudness of sound. It is the size of a vibration. The bigger the vibration is, the louder the sound it will produce. So it is safe to say that rising amplitude will result in rising volume. 

<em>Wavelength</em><em> </em>is the distance between the trough of one wave and the trough of the next wave; or the crest of one wave and the crest of the next wave. Short wavelengths mean more waves pass through a certain point at a certain time. As a result, shorter waves create higher frequencies. Longer waves, on the other hand, create lower frequencies. And using the definition of pitch above, we can then say that longer wavelengths will result in declining pitch.

An electron in a TV picture tube is accelerated through a potential difference of 10 kV before it hits the screen. What is the k
laiz [17]

Answer:

10,000 eV

Explanation:

According to the law of conservation of energy, the kinetic energy gained by the electron is equal to its change in electric potential energy:

K=\Delta U=q \Delta V

where:

K is the kinetic energy of the electron

q=1 e is the magnitude of the charge of the electron

\Delta V is the potential difference through which the electron has been accelerated

For this electron in the TV, we have

\Delta V=10 kV=10000 V

Therefore, the kinetic energy of the electron in electronvolts is

K=(1 e)(10000 V)=10000 eV
