Answer:

The correct solution is "5\times 10^{-4} %".

Explanation:

The given values are:

Pressure,

\Delta P=7\times 10^5 \ N/m

for copper,

B=14\times 10^{10} \ N/m

As we know,

The Bulk Modulus (B) = \frac{\Delta P}{-\frac{\Delta V}{V} }

or,

The decrease in volume will be:

= (\frac{\Delta V}{V})\times 100 \ percent

then,

= \frac{\Delta P}{B}\times 100 \ percent

On putting the values, we get

= \frac{7\times 10^5}{14\times 10^{10}}\times 100 \ percent

= 5\times 10^{-4} \ percent

What's a difference between mercury and oxygen?<br> (They both are elements)
borishaifa [10]

--  There are 80 protons in the nucleus of every atom of Mercury,
but only 8 of them in the nucleus of an atom of Oxygen.

-- Mercury must be warmer than 357°C in order to boil, but Oxygen
must only be warmer than -183°C.

--  Mercury must be colder than -39°C in order to freeze, but Oxygen
must be colder than -219°C.

--  Oxygen is required for human life.  Mercury is a deadly poison.

A proton at location A makes an electricfield E--&gt;1 atlocation B. A different proton, placed atlocation B, experiences a forc
luda_lava [24]

Answer:

Explanation:

 |F-->1| =  E-->1 x charge on proton

= 300 x 1.6 x 10⁻¹⁹

Magnitude of electric force on proton

|F-->1| = 480 x 10⁻¹⁹ N .

Inside lithium nucleus , there are three protons so charge on it

= 3 x 1.6 x 10⁻¹⁹ = 4.8 x 10⁻¹⁹ C .

Magnitude of electric force on lithium nucleus

|F-->Li|  =   E-->1 x charge on lithium nucleus

= 300 x  4.8 x 10⁻¹⁹

= 1440 x 10⁻¹⁹ N .

Electron has same charge as that possessed by proton so charge on electron = 1.6 x 10⁻¹⁹ C

Magnitude of force on electron

|F-->1| =  E-->1 x charge on electron

= 300 x 1.6 x 10⁻¹⁹

=  480 x 10⁻¹⁹ N .
