Before a cold front comes:The temperature will be warm.
There will be short rain showers.
During a cold front:The temperature will decrease and become cold.
There will be heavy rain with hail, thunder, and lightning.
After a cold front has passed:The temperature will continue to drop.
The rain will stop and the skies will clear.

What is one piece of evidence that does NOT support the Big Bang Theory?​
svetoff [14.1K]

Answer:

The redshift data does not support the Big Bang Theory and  without the redshift interpretation favored by the Big bang, there is  no Big Bang.  

Edwin Hubble did not believe that the redshift indicated  expansion. Hubble saw the redshift as an hitherto unrecognized  principle of nature.  The redshift is the effect of centripetal force mv2/r = mv2/ct =  v/c(mv/t) = v/c(p/t)= (v/c)m

The unrecognized principle of nature is the refraction effect of  gravity on light.  

n=c/v or v= c/n.

The Universe is older than 13.7 Billion years, likely around  16.5 billion years.  

The proper law of Gravity is W = -mGM/r + cmV = -mu/r + cP where  cP is the so-called "Dark Energy", or the actual vector Momentum  Energy cmV= cP. This is The Quaternion Universe with scalar and  vector energy!

Hope this helps!

Imagine you have a collection of identical flat-bottomed coffee filters that can be nested (stacked inside of each other) so tha
skad [1K]

Answer:

the terminal velocity of 14 nested coffee filters is 3.2 m/s

Explanation:

Given the data in the question;

we know that;

The terminal velocity is proportional to the square root of weight.

v ∝ √W

v = k√W

the proportionality constant depends upon the surface area and the density of the medium (like air). The coffee filters can be stacked such that the resulting area is roughly unchanged. So, the constant of proportionality k is also unchanged

v/√W = constant

v₂/√W₂ = v₁/√W₁

v₂ = v₁√(W₂ / W₁ )

given that;

v₁ = 0.856 m/s,

W₂ = 14W₁; meaning 14 coffee filters have 14 times the weight of a single coffee filter

so we substitute

v₂ = 0.856 √(14W₁  / W₁ )

v₂  = 0.856 √( 14( W₁/W₁)

v₂  = 0.856 √( 14(1)

v₂  = 0.856 √( 14 )

v₂  = 0.856 × 3.741657

v₂  = 3.2 m/s

Therefore, the terminal velocity of 14 nested coffee filters is 3.2 m/s

Why does a person feel cooler under a rotating fan?
sladkih [1.3K]

What a fan does is create a wind chill effect. ... By blowing air around, the fan makes it easier for the air to evaporate sweat from your skin, which is how you eliminate body heat. The more evaporation, the cooler you feel.

A ball is thrown at an angle of 38° to the horizontal. What happens to the
finlep [7]

Answer:

Vy = V0 sin 38       where Vy is the initial vertical velocity

The ball will accelerate downwards (until it lands)

Note the signs involved   if Vy is positive then g must be negative

The acceleration is constant until the ball lands

t (upwards) = (0 - Vy) / -g      = Vy / g      final velocity = 0

t(downwards = (-Vy - 0) / -g = Vy / g      final velocity = -Vy

time upwards = time downwards     (conservation laws)
