A nebula is an enormous cloud of dust and gas occupying the space between stars and acting as a nursery for new stars. The roots of the word come from Latin nebula, which means a “mist, vapor, fog, smoke, exhalation.” Nebulae are made up of dust, basic elements such as hydrogen and other ionized gases.
The correct answer is Neutron
Explanation:
As shown in the diagram the sub-particles in atoms are electrons, neutrons, and protons. From these, the two types of particles that are in the nucleus or center of the atom are neutrons and protons. Moreover, neutrons differ from protons because these are neutral or are not charged. According to this, the uncharged particles in atoms are neutrons.
Moreover, the number of neutrons can be calculated by subtracting the atomic number (number of protons) to the mass number (number of atoms and protons). For example, if in an atom the mass number is 12 (protons and neutrons)and the atomic number is 6 (number of protons), the neutrons are 6 (12 - 6 = 6). According to this, the correct answer is the neutron.
Answer:
The soil of the region A (given in the attachment) must have coarse grain sand and gravel deposits.
Explanation:
The remaining part of the question is attached here
Solution
Most of the aquifers are recharged by rainfall or either the surface water that penetrates through the soil into the ground and reaches the aquifer. Hence, the soil type in these regions must be permeable. Gravel and coarse sand along with medium seize sand particles have high permeability. Hence, the soil of the region A (given in the attachment) must have coarse grain sand and gravel deposits.
5 per 1,000 because you subtract the 10 deaths from 15 and get 5.
