B) Tellurium is a metalloid. Metalloids in some classifications are also or alternatively called “semi-metals.”
(1) a beta particle is your answer. Na-24 decays through beta decay, turning a neutron into a proton, electron (beta particle), and an neutrino.
Atoms (Sodium and Fluorine)
Answer:
The new acceleration becomes twice the pervious acceleration.
Explanation:
Given that,
Mass of the rock, m = 3 kg
Force, F = 1 N
We know that the force acting on an object is given by :
F = ma
a is acceleration of the rock
Put m = 3 kg and F = 1N,

If the force is doubled, F' = 2 N
So,
F'=ma'

So, the new acceleration becomes twice the initial acceleration.
There are 12 Hydrogens (H) and 12 Oxygens (O) and 6 molecules of Hydrogen Peroxide (H2O2) reacted
