Shtirlitz [24]
The balloon has traveled 30 meters up from the bicyclist and since it's rising 5 meters per second, 2 seconds later it will travel 10 meters higher. 2 seconds later the bicyclist will travel 20 meters away.   so 10+20+30= 60 meters away from each other.

vivado [14]

igneous rocks cool very slowly

Explanation:

Large crystals are formed when rocks cool very slowly. This gives time for crystallization nuclei to form and other crystals aggregates round it.

  • Large crystals in rocks are typical of intrusive igneous rocks.
  • These rocks are formed beneath the earth surface and they usually have big crystals.
  • This because they cool slowly and have time for crystal formation.
  • Rocks that cools rapidly are extrusive igneous rocks.
  • They are usually fine grained and glassy in nature.

write a correct and complete nuclear equation for the alpha decay of a parent atom having 102 protons and 167 neutrons useing th
scZoUnD [109]
Alpha partical is a He nucleus. When decaying alpha particle mass is reduced by 4 and atomic number is reduced by 2.

The actual element which has 102 protons is No (Nobelium). 
Since it has 167 neutrons, the mass = protons + neutrons = 102 + 167 = 269

after an alpha decay, the new element formed has 100 protons which is Fm ( Fermium)

the alpha decaying equation is,

    ₁₀₂²⁶⁹No → ₁₀₀²⁶⁵Fm + ₂⁴α + heat

the total mass and the atomic number( numbe rof protons) must be equal in both sides.
