AMSWER:

There are two main types of radiation that can be given off during radioactive decay. The first is particle radiation. It includes alpha and beta particles as well as proton and neutron radiation. The second is electromagnetic radiation.

EXPLANATION:

Radioactive decay is the process by which an atomic nucleus emits particles or electromagnetic radiation to become either a different isotope of the same element or an atom of a different element.

If you had a known sample of a mineral whose density was 7.1 grams/ml and its volume was 15 ml. What is the mass of the mineral.

kow [346]

Answer:

<h3>The answer is 106.5 g</h3>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

volume = 15 mL

density = 7.1 g/mL

We have

mass = 7.1 × 15

We have the final answer as

What is the resistance of 1.0 m of a solid cylindrical metal cable having a diameter of 0.40 inches and a resistivity of 1.68 ×

Dahasolnce [82]

Given;

redistivity =1.68/100000000W.m

diameter =0.40in

=0.01016m

length =1m

resistance =?

redistivity =resistance×area/lenght

restance=resistivity × length /area

so, resistance =1.6535/1000000 ohmn

Answer:

300000.01008 Pa

123.76237 m/s²

Explanation:

$\rho$ = Density of liquid nitrogen = 808 kg/m³

h = Depth

g = Acceleration due to gravity

P = Atmospheric pressure

Absolute Pressure is given by

Below 2 m from surface

$P_a=P+\rho gh\\\Rightarrow 5\times 10^5=P+808g\times 2$

Below 5 m from surface

$P_a=P+\rho gh\\\Rightarrow 8\times 10^5=P+808g\times 5$

Subtracting the above equations we get

$-3\times 10^5=-808g3\\\Rightarrow g=\frac{3\times 10^5}{808\times 3}\\\Rightarrow g=123.76237\ m/s^2$

The acceleration due to gravity on the planet is 123.76237 m/s²

Equating the value of g in the first equation

$5\times 10^5=P+808\times 123.76237\times 2\\\Rightarrow P=5\times 10^5-808\times 123.76237\times 2\\\Rightarrow P=300000.01008\ Pa$

The atmospheric pressure on the planet is 300000.01008 Pa
