The alpha particles that were fired at the gold foil were positively charged. ... These experiments led Rutherford to describe the atom as containing mostly empty space, with a very small, dense, positively charged nucleus at the center, which contained most of the mass of the atom, with the electrons orbiting the nucleus.
The answer woulda be C - Pure substance
The correct answer is option A, that is, cooler and more rigid outer portion.
The lithosphere of the Earth comprises the crust and the uppermost mantle that forms the rigid and hard outer layer of the Earth. The lithosphere is sub-differentiated into tectonic plates. The topmost section of the lithosphere, which chemically reacts with the hydrosphere, atmosphere, and biosphere via the soil producing procedure is known as the pedosphere. The lithosphere is situated above the asthenosphere that is the hotter, weaker, and deeper component of the upper mantle.
Called a(n) convection current
The cars are hanging from cables so that there is presence of more medium of propagation to make it look real.
<h3>What is a Blast wave?</h3>
This is referred to as a violent propagating disturbance, produced by an explosion in air.
Hanging the cars in the air will ensure an accurate description of the effect of the blast wave on them.
