Answer:
<h3>The answer is 20 g/cm³</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 16,000 g
volume = 800 cm³
We have
We have the final answer as
<h3>20 g/cm³</h3>
Hope this helps you
The half-life of Th-232 is 1.405 × 10¹⁰ years
Time elapsed = 2.8 x 10⁹ years
Equation of radioactive decay:
A = A₀ = (1/2)^ t/t₁/₂
Thus, the percentage of thorium-232 in the rock that was dated at 2.8 billions year = 87.1%
Answer:
Hit the pot faster at a higher frequency
Explanation:
I feel like it would be because it makes more sense to me but I really have no clue tbh
If the angle is either 0 or 180, that means that there is either negative or positive work, so A and D are not correct.
If the angle is 45, then there is still some work involved.
The only option where there is no work done by a force is B. when the angle is between the force and displacement is 90.
Because if they are submerged in the solvent, they would dissolve! This would prevent them from seperating and not allow you to actually record anything
