What measures air pressure.?
Alekssandra [29.7K]
That depends on what type of pressure you are attempting to measure, to measure Atmospheric pressure, you would use a Barometer. To measure things like tires, you could use a Tire Pressure Gauge. For Industrial processes and boilers, you would use a Manometer. For pressure vessels, you would use a Bordon Gauge.   <span />

A body in simple harmonic motion has a displacement x that varies in time t according to the equation x = 5cos(π t + π/3) , wher
zhuklara [117]

Answer:

1/2 Hz

Explanation:

A simple harmonic motion has an equation in the form of

x(t) = Acos(\omega t - \phi)

where A is the amplitude, \omega = 2\pi f is the angular frequency and \phi is the initial phase.

Since our body has an equation of  x = 5cos(π t + π/3) we can equate \omega = \pi and solve for frequency f

2\pi f = \pi

f = 1/2 Hz

N capacitors are connected in parallel to form a "capacitor circuit". The capacitance of first capacitor is C, second one is C/2
liberstina [14]

Answer:

2C

Explanation:

The equivalent capacitance of a parallel combination of capacitors is the sum of their capacitance.

So, if the capacitance of each capacitor is half the previous one, we have a geometric series with first term = C and rate = 0.5.

Using the formula for the sum of the infinite terms of a geometric series, we have:

Sum = First term / (1 - rate)

Sum = C / (1 - 0.5)

Sum = C / 0.5 = 2C

So the equivalent capacitance of this parallel connection is 2C.

1.) because then people can evacuate the area in the path<span> of the hurricane.
2.) </span><span>At higher altitudes, water vapor starts to condense into clouds and rain, releasing heat that warms the surrounding air, Which makes it rise as well. Warmer waters feed more energetic storms.
3.) </span> <span>A hurricane starts off as a series of thunderstorms which intensify as it moves over the warm and humid sea. The humidity is at a constant level and so it continues to grow over the sea. Any kind of decrease or increase in humidity can change the strength of a hurricane. 
4.) </span><span>Actually, tropical cyclones need weak winds. If the atmospheric winds are even remotely strong, they will act to cut back the system and prevent the convection from wrapping around the center.

5.) That hard to tell, it could be too much. Though I am going to go with yes. Cyclones need weak winds and good amount humidity.</span><span>
