Which statement about tornadoes is correct? a. They are a very common part of thunderstorms. b. Seventy-five percent of the worl

Anit [1.1K]

As strange as it may seem, around 75% world’s tornadoes

occur in the United States. It's actually because of the unique

geography of North America, and how the winds and storms

get funneled up through the US. (choice-b)

It's true that when there's a tornado, it usually comes along with a thunderstorm. But tornadoes are way way LESS common than thunderstorms.

Their main danger is from the high winds in the center of the funnel.

The rain is minor compared to the wind damage.

Tornadoes are not really the strongest storms on Earth.

Welll ... I guess that could depend on what "strong storm" means.

Sure, a tornado is incredibly vicious and powerful. But it's only a few

miles wide, and it only lasts for a few hours and then it's all over.

The tropical cyclones ... hurricanes, monsoons, typhoons ... don't have

winds as fast as tornadoes, but they can be a thousand miles wide and

last for weeks.

Answer:

The part of the wave is the Amplitude.

Reason: The amplitude of light waves is responsible for our perception of brightness, with larger amplitudes appearing brighter than lower amplitudes.

Explanation:

The amplitude of light waves is responsible for our perception of brightness, with larger amplitudes appearing brighter than lower amplitudes.

Thus, when you turn up the brightness of the light so that you can better see, you are increasing the amplitude of the light wave, which in turn increases the intensity of the light, seen from the increased brightness of the flash light.

What is the frequency if 140 waves pass in 2 minutes?

Paha777 [63]

Answer:

1.16 Hz

Explanation:

frequency, basically, is the number of wave on 1 second

so, in math we write like this

f = n/t

n = number of waves

t = time to do that (in sec)

f = 140/120 = 7/6 Hz

f = 1.16 Hz

Two devices with capacitances of 25 μf and 5.0 μf are each charged with separate 120 v power supplies. calculate the total energ

mash [69]

The energy stored in a capacitor is given by
$U= \frac{1}{2} CV^2$
where C is the value of the capacitance while V is the voltage difference applied to the capacitor.

Let's calculate the energy of the first capacitor:
$U_1 = \frac{1}{2} (25\cdot 10^{-6}F)(120 V)=1.5 \cdot 10^{-3}J$

And now the energy of the second capacitor:
$U_2 = \frac{1}{2} (5 \cdot 10^{-6}F)(120 V)=3 \cdot 10^{-4}J$

So, the total energy stored in the two capacitors is
$U=U_1 +U_2 = 1.8 \cdot 10^{-3}J$
