Emissions from alpha decay require the least amount of shielding.

Physics

The particles released during alpha decay are called alpha particles. Alpha particles have greater mass and charge than other emitted particles.

  • Radioactive emissions are the transfer of energy through the flow of particles or waves in a medium
  • There are 3 types of radioactive emissions which are alpha, beta and gamma
  • In alpha radiation, the nucleus emits an alpha particle which is equivalent to a helium nucleus
  • In beta radiation, an electron is emitted to convert a neutron to a proton
  • In gamma radiation, the nucleus just loses energy

Since alpha particles have more mass and charge, they are more ionising and lose more energy at a faster rate and can be blocked easily.

The earth travels around the sun once a year in an approximately circular orbit whose radius is 1.50x10^11 m. From this data det
seraphim [82]
(a) Determine the circumference of the Earth through the equation,
            C = 2πr
Substituting the known values, 
           C = 2π(1.50 x 10¹¹ m)
             C = 9.424 x 10¹¹ m

Then, divide the answer by time which is given to a year which is equal to 31536000 s. 
          orbital speed = (9.424 x 10¹¹ m)/31536000 s

               orbital speed = 29883.307 m/s

Hence, the orbital speed of the Earth is ~29883.307 m/s.

(b) The mass of the sun is ~1.9891 x 10³⁰ kg.

A battery has a potential resistance of 12 V and a current of 1280 mA. What is the resistance? PLS HELP ME ASAPPPPPPPPPP
Romashka-Z-Leto [24]

Resistance (R) = <u>9.375 ohm (Ω)</u>

Steps:

R =   \frac{V}{I}

=    \frac{12 \: volt}{1280 \:  milliampere}

=  \frac{12 \: volt}{1.28 \: ampare}

= 9.375 \: ohm (Ω)

How does solubility change with temperature changes?
matrenka [14]

Answer:

Solubility increases with temperature.

Explanation:

-Increasing temperatures, increases the kinetic energy that allows solvent molecules to more effectively break apart the solute molecules.

-This solute molecules are held together by intermolecular attractions which weakens in higher temperatures.

-Solubility therefore increases with increasing temperatures.

Which component of magma includes mobile ions of silicon?
Lemur [1.5K]

Answer:

Melt.

Explanation:

When rocks melt, they do so slowly and gradually because most rocks are made of several minerals, which all have different melting points; moreover, the physical and chemical relationships controlling the melting are complex. As a rock melts, for example, its volume changes. When enough rock is melted, the small globules of melt link up and soften the rock.

Under normal conditions, mantle rock like peridotite shouldn't melt in the Earth's upper mantle. However, by adding water you can lower the melting point of the rock. Alternatively, by decompressing the rock, you can bring it to a pressure where the melting point is lower. In both cases, basalt magma will form and considering it is hotter and less dense than the surrounding rock, it will percolate towards the surface and some of that erupts.
