Would the remains of a living thing have more or less carbon 14 in it after being buried for 10000 years? Why? Please make the answer no more than 5 sentences

Answers

Answer 1
Answer: Yes, because carbon-14 is radioactive and so decays over time. if it is buried, it cannot take up more carbon-14, so the overall c14 levels wil go down.

D is the correct process to convert 36 yds to centimetres 2.54 cm = 1 in.

What are centimetres?

A metric unit of length, equal to one-hundredth of a metre.

To convert a yard measurement to a centimetre measurement, multiply the length by the conversion ratio. The length in centimeters is equal to the yards multiplied by 91.44.

Backpackers often use canisters of white gas to fuel a cooking stove's burner. If one canister contains 1.45 L of white gas, and the density of the gas is 0.710 g/cm3, how many kilograms of fuel are contained in one canister?

Answers

The number of  kilograms  of fuel   that are contained in one  canister  is 1.03 Kilograms


calculation

mass =  density x  volume

Density= 0.710 g/cm³

volume = 1.45 L

convert  1.45 l into cm³  to make the units  uniform

that is     1 L= 1000 cm³

              1.45 L=  cm³

by cross  multiplication

= (1.45 L  x 1000 cm³)  / 1 L  = 1450 cm³


mass is therefore =   0.710g/cm³  x 1450 cm³   =1029.5 grams


convert grams to Kg

1 kg = 1000 grams

  ? kg  =1029.5  grams

by cross  multiplication

= (1 kg  x 1029.5 grams) /1000 grams  = 1.0295 Kg ≅1.03 kg



the canister contains a gas used to fuel a burner

the volume of the white gas to be used is - 1.45 L

density of white gas is 0.710 g/cm³

density is defined as the mass per unit volume

the mass of 1 cm³ of white gas is - 0.710 g

1 cm³ is equivalent to 0.001 L

the volume given is in Litres

so if 0.001 L has a mass of 0.710 g

then 1.45 L have a mass of - 0.710 g / 0.001 L x 1.45 L = 1030 g

since 1000 g is equivalent to 1 kg

mass of white fuel is - 1030 g/1000 g/kg = 1.03 kg

theres 1.03 kg of fuel in one canister

Why do plants grow faster without sun?

Answers

Plants rely on photosynthesis to create energy for all of their cellular functions. The more sun the plant takes in, the more energy it is able to produce, thus allowing it to grow faster.
