Answer:

Gaining electrons

Explanation:

Anions are negatively charged ions.

When an atom gains some electrons then anions are formed.

As electrons are negatively charged so anions are also negatively charged ions.

Anions are attracted by the cathode which is positively charged electrode.

Apples are stored in a container (width = length = 3.5 ft) that is filled to a depth of 2.75 feet. If the unit density of an app
Agata [3.3K]

Answer:

The mass of the apples in the box are 1145.95 lb.

Explanation:

Given that,

Width = 3.5 ft

length = 3.5 ft

Depth = 2.75 feet

Density = 49.3 lb/ft³

We need to calculate the volume

Using formula of volume

V=l\times h\times b

Put the value

V=3.5\times3.5\times2.75

V=33.6875\ ft^3

We need to calculate the mass

Using formula of density

\rho=\dfraxc{m}{V}

m=\rho\timesV

Put the value into the formula

m=49.3\times33.6875

m=1660.79\ lb

But porosity is 31 % so apples is 69% mass of total container.

So, Total mass in pounds is

M=\dfrac{69}{100}\times1660.79

M=1145.95\ lb

Hence, The mass of the apples in the box are 1145.95 lb.

A sample of Bismuth-212 has a mass of 2.64 grams (g) after 121 seconds (s). What was the initial mass of the sample if Bismuth-2
uysha [10]
The mass of a radioactive element at time t is given by
m(t) = m_0 ( \frac{1}{2} )^{ \frac{t}{t_{1/2}} }
where m_0 is the mass at time zero, while t_{1/2} is the half-life of the element.

In our problem, m(t)=2.64 g, t=121.0 s and t_{1/2}=60.5 s, so we can find the initial mass m_0:
m_0= \frac{m(t)}{ (\frac{1}{2})^{t/t_{1/2}} } = \frac{2.64 g}{( \frac{1}{2} )^{121/60.5}} =4 \cdot 2.64 g=10.56 g
