Answer:

The density of the material is 7.5 g/m^3

Explanation:

The volume of a rectangle is:

Volume = Length*Height*Width

Replacing with data:

Volume = 5 m * 2 m * 4 m = 40 m^3

Density is computed as follows:

Density = Mass/Volume

Replacing with data:

Density = 300 g/40 m^3

Density = 7.5 g/m^3

How many electrons flow through a point in a wire in 3.00 s if there is a constant current of i=4.00a ?
MaRussiya [10]

7.5 × 10¹⁹ Electrons flow through a point in a wire in 3.00 s if there is a constant current of i=4.00a.

Q = I × t------------Equation 1

Where Q = charge flowing through the wire, I = current, t = time

Given: I = 4.00 A, t = 3.00 s

Substitute these values into equation 1

Q = 4.00× 3.00

Q = 12.00 C.

But,

1 electron contains 1.6×10⁻¹⁹ C

therefore,

12.00 C = 12.00/1.6×10⁻¹⁹  electrons

= 7.5 × 10¹⁹ Electrons

Uranium–232 has a half–life of 68. 9 years. A sample from 206. 7 years ago contains 1. 40 g of uranium–232. How much uranium was
ioda

Half-life can be given as the time required by the substance to reduce to half of its original concentration. The original mass of Uranium was 11.2 grams.

<h3>What is the expression of half-life?</h3>

The half-life for the reaction can be expressed as;

A_t=A_0(\dfrac{1}{2})^\dfrac{t}{t1/2}

Where the final mass of the product is, A_t=1.40\;\rm g

The time for the reduction is given as, t=206.7\;\rm years

The half-life of the compound is given as, t1/2=68.9\;\rm years

The original concentration (A_0) of the Uranium is given as,

\rm 1.40\;g=\textit A_0(\dfrac{1}{2} )^{\dfrac{206.7}{68.9}}\\\\1.40\;g= \textit A_0(\dfrac{1}{2} )^3\\\\\textit A_0=11.2\;\rm grams

The original mass of uranium-232 has been 11.2 grams.
