The type of investigation is she is conducting by determining the period in which it is from is referred to as the geologic age.
<h3>What is Geologic age?</h3>
This is defined as the time period in which the fossil was present on the earth and can be done using various methods such as radiometric dating methods etc. The age gotten will help scientists to ascertain different information about the organism in this context.
Fossil on the other hand which is the remains of organisms preserved in the earth crust can be studied to find out the differences in the features of organisms and how they were able to adapt to the changing environmental conditions.

Answer:
a rope being pulled from both sides with equal force
Explanation:
:)
Thermal energy comes from the ,movement of particles which produces heat, the faster the movement is the more heat
Answer:
Common velocity will be 2 m/sec
Explanation:
We have given a car of mass 1000 kg is traveling in east at 20 m /sec
So 
and 
( take east direction as positive )
And another car of mass 1500 kg is moving with 10 m/sec in west direction
So 
and 
( west direction will be negative direction )
According to law of conservation of momentum
So common velocity will be 2 m/sec
It is given that total amount of oxygen in the reactants is 4 atoms to balance this chemical equation it is necessary that total number of reactant molecules should equal the total number of products.
Explanation:
The coefficients are found by counting each individual atom and atom numbers are same in reactants and products.
Without balancing the equation the formation is H2O and O2. The total number of oxygen in the product side is 3. Hence to balance this equation multiply H2O by 2 and O2 by 1. Thus the total of 4 O2 atoms will be formed on the product side.
Therefore, We can say that the coefficient 2 should be placed in front of water and and 1 in front of oxygen.
