the fossil informed us about the climatic and geographical changes that occurs in the environment over time.

<h3>What the mystery fossil dig site informed us about environment?</h3>

We can infer about the climate and geographical changes in the environment over time at the mystery fossil dig site because the fossil provides us information about the climatic condition as well as the geography of land when this fossil organism were alive.

So we can conclude that the fossil informed us about the climatic and geographical changes that occurs in the environment over time.

1. Have you ever tried to undergo an X-ray to test on your body? What can you see in the fils aftee the examination? why is the
lora16 [44]

Answer:

Explanation:

1. What is seen after the x-ray examination is the "picture" of the bone. X-rays are ionizing radiation that produce picture of bones when the body is subjected to the rays.

The bone is visible because the rays cannot penetrate hard surfaces like bones but can penetrate tissues and organs that are soft. Hence, the "picture" seen is just a shadow cast by the bones.

2. Airports and most transportation stations use thermal devices such as infrared thermometers to check for a spike in temperature of passengers. This is because symptomatic carriers of the virus will normally run a high temperature or fever.

3. When white light passes through a prism, the incident ray of the white disperses to produce different constituent colours (which can be seen if done practically).

A physical quantity X is connected from X = ab2/C. Calculate percentage error in X, when percentage error in a,b,c are 4,2 and 3
Ostrovityanka [42]

Answer:

9.5%

Explanation:

Missing information :

In this question there is incorrect question .The correct question is

x\ =\frac{ab^{2} }{\sqrt{c} }

Given :

x\ =\ \frac{ab^{2} }{\sqrt{c} }

From the propagation of error property

$\Delta$x  =   $\Delta$a  +  2$\Delta$b  +  1$\Delta$c\\\       \ \ x   =    \ \ a   +       \ \ \ \ b  +    \ \ \ \ c \\----------------------Eq(1)

Putting the respective value 4,2 and 3 in the Eq(1) we get

This gives

percentage \ error \ = 4\ +\ 2*2\ +\ \frac{3}{2}\\ percentage \ error \ =  4+4+\frac{3}{2} \\percentage \ error \ = 8+\frac{3}{2}\\ percentage \ error \ = 8+1.5\\percentage \ error \ = 9.5\\Therefore \ 9.5\%
