Answer:
The mammoth bone is 22726 years old.
Explanation:
We can find how hold is the mammoth bone using the decay equation:
(1)
Where:
N(t): is the quantity at time t = 6.25%N₀
N₀: is the initial quantity
λ: is the decay constant
First, we need to find λ:
Now, by solving equation (1) for t we have:
Therefore, the mammoth bone is 22726 years old.
I hope it helps you!
Answer:
The correct answer is certainly true.
Explanation:
You first need to fully understand the conflict/problem before explaining it.
Most students do this when doing a research project.
For example: Let's say I had a project to explain solutions for climate change but I didn't even know what it is and how it was caused. Well of course your teacher will make you research the topic in order to represent it correctly.
While a bug fly in the air the weight of bug is counter balanced by the buoyancy force that is applied by air on the bug
This buoyancy force is net upthrust on the bug due to air which will help the bug to float in the air
This buoyancy force is given by the formula
here we know that
= density of air
V = volume of bug
so here we can say that upthrust of air is the force that bug will experience during his uplift
The Correct answer to number 1 is A or D
The correct answer to number 2 is C because transmission meaning is to travel.
PS. I think number 1 is D
Answer:
72J
Explanation:
distance moved is equal to 3m.then just substitute x with 3m.
Fx = (14(3) - 3.0(3)2)) N
Fx =(42-18)N
Fx =24N
W=Fx *S
W=24N*3m
W=72J
