What is your acceleration while sitting in your chair. the latitude of corvallis is 44.4˚.?
marta [7]
 <span>You can start with the equations you know 

a=v^2/r = (2pi*r/T)^2/r = 4pi^2r/T^2 

Radius of earth (R) = 6378.1 km 
Time in one day (T) = 86400 seconds 
Latitude = 44.4 degrees 

If you draw a circle and have the radius going out at a 44.4 degree angle above the center you can then find the r. 

r=Rcos(44.4) 
r=6378.1cos(44.4) 
r= 4556.978198 km or 4556978 m 

Now you can plug this value into the acceleration equation from above... 

a= 1.8*10^8/7.47*10^9 
a= .0241 m/s^2 </span>

1. Nyatakan prinsip Bernoulli.​
nignag [31]

Answer:

prinsip bernoulli

Explanation:

Prinsip Bernoulli adalah sebuah istilah di dalam mekanika fluida yang menyatakan bahwa pada suatu aliran fluida, peningkatan pada kecepatan fluida akan menimbulkan penurunan tekanan pada aliran tersebut. Prinsip ini sebenarnya merupakan penyederhanaan dari Persamaan Bernoulli yang menyatakan bahwa jumlah energi pada suatu titik di dalam suatu aliran tertutup sama besarnya dengan jumlah energi di titik lain pada jalur aliran yang sama. Prinsip ini diambil dari nama ilmuwan Belanda/Swiss yang bernama Daniel Bernoulli.

Does the sun always shine directly overhead at the equator at noon
Nikitich [7]
The sun always shines directly overhead at noon. This is because the equator always gets the equivalent amount of sunlight. The area always get 12 hours of sunlight, because it's 0 degrees north and south and it's at the center of the Earth.

Explain the increase in pressure of a gas when its volume is decreased at constant<br> temperature.
Dmitriy789 [7]

Answer:

For a gas held at constant temperature, we can apply Boyle's law, which states that the product between the gas pressure and its volume is constant:

PV=const.

where

P is the pressure

V is the volume

As we see from the equation, P and V are inversely proportional to each other: this means that when the volume is decreased, the pressure increases, and vice-versa. The reason for that is that when the volume is decreased, the gas is compressed, so the molecules of the gas come closer to each other, so they collide more frequently with the wall of the container, exerting therefore a greater pressure.
