The equation is balanced because the mass and charge are equal on both sides of the reaction equation.
In a nuclear reaction, one nucleus is transformed into another. In this case of the equation shown, the radon nucleus is being transformed into a polonium nucleus with the emission of an alpha particle.
The equation is balanced because a total mass of 219 is found on both sides of the reaction equation and a total charge of 86. Recall that an alpha particle is the same as a helium nucleus with a mass of four units and a charge of two units.

Answer:
Creation of mid-ocean ridges, creation of new mountains, formation of earthquakes, and formation of volcanoes.
Explanation:
The convergent boundary plate tectonic comprises collisions between the continental and oceanic plates. The less dense and thinner oceanic plate gets overridden by the more denser and thicker continental plate. The ocean plate is forced down the mantle, and the event is called subduction.
The magma found in the mantle leads to melting of the subduction plates. The magma gets within the plates via pores. This magma plate turns buoyant and moves in an upward direction. The molten magma leads to volcanic eruptions along with earthquakes. The solidification of magma in the subduction zone leads to the formation of ocean ridges. The formation of mountains close to the continents takes place when the magma after the volcanic eruption gets cooled and solidifies.

Answer:
A.when it reaches the top of its flight
Explanation:
This theory is base on gravitational potential energy which state that potential energy in an object increases as weight and height increases.
the amount of potential energy stored by an object depend s on the mass and height.
