0.008 μg of americium-241 was consumed in a smoke detector
The half life of a substance is:
[tex]N=N_o(\frac{1}{2} )^\frac{t}{t_\frac{1}{2} } \\\\Where\ N\ is\ the \ amount \ of\ substance\ remaining\ after\ t\ years,\\N_o\ is\ the\ original\ amount, t_\frac{1}{2} \ is\ half\ life.\\\\\\Given\ N_o=5\ \mu g,t=1\ year,t_\frac{1}{2} =433\ years. Hence:\\\\N=5*10^{-6}(\frac{1}{2} )^\frac{1}{433} =4.992\ \mu g[/tex]
The amount consumed = 5 - 4.992 = 0.008 μg

Which of the following can be best explained by temporary dipole moments?.
How can you turn conflict into a positive experience brainly.
A car is traveling with a constant speed when the driver suddenly applies the brakes, causing the car to slow down with a constant acceleration of magnitude 3. 50 m/s2. If the car comes to a stop in a distance of 30. 0 m, what was the car's original speed?.
Answer: 14.49 m/s
Explanation: you would have to use kinematic equations to solve for the original speed.
v^2 = v0^2 + 2 (a) (x) where v = 0 since the car stopped
then you would get v0 = sqrt (2(a)(x))
plug in the known values
v0 = sqrt(2(3.50)(30.0))
v0 = 14.49 m/s
So the answer would be 14.49 m/s

What is the value of x in the equation 2 (6 x 4) minus 6 2 x = 3 (4 x 3) 1? 1 3 4 6.
Answer:
4
Step-by-step explanation:
2 (6 x + 4) - 6 + 2 x = 3 (4 x + 3) + 1
12x + 8 - 6 + 2x = 12x + 9 + 1
12x + 2 + 2x = 12x + 10
2x + 2 = 10
2x = 10 - 2
2x = 8
x = 4

Which best describes the first law of thermodynamics as compared to the second law of thermodynamics? The first law describes how thermal energy is conserved but not the direction it moves. The first law describes the direction thermal energy moves but not how it is conserved. The first law describes how thermal energy can be created but not how it can be destroyed. The first law describes how thermal energy can be destroyed but not how it can be created.
The statement which best describes the difference between the first law of thermodynamics in comparison with the second law of thermodynamics is that: A. The first law describes how thermal energy is conserved but not the direction it moves.
The First Law of Thermodynamics states that energy can neither be created nor destroyed but it can only be transformed (converted) from one form to another such as potential energy to kinetic energy. Thus, thermal energy is always conserved according to the First Law of Thermodynamics.
On the other hand, the Second Law of Thermodynamics states that the entropy (disorderliness) of an isolated system always increases and can never be decreased. Thus, the direction of an energy is described by the Second Law of Thermodynamics.
In conclusion, the difference between the First Law of Thermodynamics in comparison with the Second Law of Thermodynamics is that the first law describes how thermal energy is conserved but not the direction in which thermal energy moves.

What is Disributive property?We can divide anything into portions when you distribute it. The distributive property in mathematics breaks down expressions into the sum or difference of two integers, which makes it easier to solve complex problems.
This concept states that multiplying the sum of two addends by a number will produce the same outcome as multiplying each addend separately by the number and then adding the results.
The distributive property, sometimes known as the distributive property of multiplication, tells us how to solve certain algebraic expressions that include both multiplication and addition.
