What weather does a occluded front bring?

8090 [49]

Hey I hope this helps in any way.

As the front moves through, cool, fair weather is likely to follow. Warm front Forms when a moist, warm air mass slides up and over a cold air mass. As the warm air mass rises, it condenses into a broad area of clouds. A warm front brings gentle rain or light snow, followed by warmer, milder weather.

Earth has a surface area of 197 million square miles. Convert this area into each of the following units.

slamgirl [31]

Answers:

a) $510,225,121.4 km^{2}$

We know the Earth's surface area in square miles is:

$197000000 mi^{2}$

On the other hand, we know $1 mi=1.60934 km$ .

Then:

$197000000 mi^{2} \frac{(1.60934 km)^{2}}{1 mi^{2}}=510,225,121.4 km^{2}$

b) $510.225 Mm^{2}$

In this part, we can work with the obtained value in part a:

$510,225,121.4 km^{2}$

And knowing $1 km=0.001 Mm$

Hence:

$510,225,121.4 km^{2} \frac{(0.001 Mm)^{2}}{1 km^{2}}=510.225 Mm^{2}$

c) $5.1022(10)^{16} dm^{2}$

Knowing $1 Mm=10^{7} dm$ :

$510.225 Mm^{2} \frac{(10^{7} dm)^{2}}{1 Mm^{2}}=5.1022(10)^{16} dm^{2}$

How do organ systems work together to deliver nutrients from food throughout the body

navik [9.2K]

most tasks in the body need the support of two or more organ systems working together. Take cellular respiration for instance. this task requires oxygen and food. Th e respiratory system brings oxygen into the lungs when you breathe. Th e digestive system breaks food down into nutrients such as glucose.

The radius of Earth is 6370 km in the Earth reference frame. The cosmic ray is moving at 0.880Co relative to Earth.

Blababa [14]

Answer:

6052114.67492 m

$12.742\times 10^{6}\ m$

Explanation:

v = Velocity of cosmic ray = 0.88c

c = Speed of light = $3\times 10^8\ m/s$

d = Width of Earth = Diameter of Earth = $12.742\times 10^{6}\ m$

When the cosmic ray is moving towards Earth then in the frame of the cosmic ray the width of the Earth appears smaller than the original

This happens due to length contraction

Length contraction is given by

$d_e=d\sqrt{1-\frac{v^2}{c^2}}\\\Rightarrow d_e=12.742\times 10^{6}\sqrt{1-\frac{0.88^2c^2}{c^2}}\\\Rightarrow d_e=6052114.67492\ m$

The Earth's width is 6052114.67492 m

Contraction only occurs in the cosmic ray's frame of reference in the direction of the ray. But in perpendicular direction the width remains unchanged.

Hence, the width is $12.742\times 10^{6}\ m$
