How are the functions of the mouth and stomach similar to each other

Use Table 1: Analysis of Decay in the laboratory guide to answer this question: Scientists find a piece of wood that is thought

Sladkaya [172]

We are given the initial amount of 1 million carbon-14 atoms and the final amount which is 1/16 of the current atmospheric 14C levels. Also, the half life of carbon is 5,750 years. WE can use the decay formula

Aₓ = A₀e^-(ln2/t1/2)t
1,000,000(1/16) = (1,000,000)e^-(ln2/5750)t
t = 23,000 years

1. Though Florida receives a lot of rainfall, only 1 percent remains available for people to use or drink. What happens to the r

timama [110]

I am sure these answers are correct cause I've checked all of them. Here they are :

1) The thing which might happen to the rest of the water is that 61% of that water leaves the ground through evapotranspiration and 38% will flow into the Atlantic Ocean.

2) The four states which receive drinking water from Florida are : South Carolina, Georgia, Alabama, Mississippi

3) The reason why people in Florida wanted to get rid of the water in certain areas is abundance of wetlands. I think there is one more, if it is acceptable I suggest you using this - frequent flooding.

4) The negative result of the changes which people made to get rid of the water is the first sign of drought.

5) The thing that has been done to try and improve those mistakes was creating a tool which looked like a dam to prevent dfficulties with navigating the state.

Hope that helps.

Compare and contrast alpha beta and gamma radiation

Evgen [1.6K]

There are usually 3 topics used to compare types of radiation:

Ionising ability
Penetrative power
Range in air

Ionising ability
Alpha radiation has strong ionising ability, while beta only has moderate ionisation and gamma is very weakly ionising.

Penetrative power
Alpha particles are weakly penetrating, stopped by paper, while beta particles have stronger penetrating ability, stopped by skin and gamma radiation is very strongly penetrating, stopped only by thick layers of lead.

Range in air
Alpha particles- range of only a few centimetres
Beta - range of up to one meter
Gamma- infinite range in air.

Hope this helps:)
