True, rocks are made from hardened magma from the Earth’s interior. By studying them you can find out a lot about the interior.

I had a carved lava rock necklace when I was a kid & lived in Hawaii. My sister & I developed a rash from wearing the lava rock pendant. We think it was because there was a high level of sulfur in the lava rock.

If you have ever been near an active volcano, the smoke/ steam gives off a smell of sulfur, which smells like rotten

In nuclear fission, a nucleus splits roughly in half. (a) What is the potential 2.00 × 10−14 m from a fragment that has 46 proto
Valentin [98]

Answer:

electric potential is 3.31 × 10^{6} V

potential energy is 152 MeV

Explanation:

given data

fragment charge  Q = 46 protons = 46 × 1.6 × 10^{-19} C

to find out

electric potential  and potential energy

solution

we know here distance from fragment d = 2 × 10^{-14} m

and constant for electric force k that is 9 × 10^{9} N-m²/C²

so that we can find electric potential = kQ/d

electric potential = 9 × 10^{9}[/tex ×46 × 1.6 × [tex]10^{-19} / ( 2 × 10^{-14} )

electric potential = 3.31 × 10^{6} V

and

we know relation between electric potential and potential

that is  V = U/q

so U will be = qV

now put all value

we get potential energy U

potential energy = 46 × 3.31 × 10^{6}

potential energy = 1.52 × 10^{8} eV

so potential energy = 152 MeV

A satellite is launched to orbit the Earth at an altitude of 2.90 x10^7 m for use in the Global Positioning System (GPS). Take t
marin [14]

Answer:

T=66262.4s

Explanation:

From the question we are told that:

Altitude A=2.90 *10^7

Mass m=5.97 * 10^{24} kg

Radius r=6.38 *10^6 m.

Generally the equation for Satellite Speed is mathematically given by

V=(\frac{GM}{d} )^{0.5}

V=(\frac{6.67*10^{-11}*5.97 * 10^{24}}{6.38 *10^6+2.90 *10^7} )^{0.5}

V=3354.83m/s

Therefore

Period T is Given as

T=\frac{2 \pi *a}{V}

T=\frac{2 \pi *(6.38 *10^6+2.90 *10^7}{3354.83}

T=66262.4s
