ISOTOPES (C) are atoms with the same number of protons, but different numbers of neutrons.

Explanation:
The principle of uniformitarianism was proposed by James Hutton, a Scottish geologist to explain geologic processes and how they relate in space.
According to the principle "the present is the key to the past and geologic process occurring today have occurred in times past. ".
- Saddled with this knowledge, geologists can understand and unravel how rocks form and how the earth has been sculpted.
- Today, in some places on earth, we see volcanic activities.
- Such a place is on the Hawaiian Islands where hot plumes are coming to the surface.
- In like manner, the lava cools and solidifies to form new volcanic basalt.
- Using this knowledge, any geologist can unravel any igneous rock.
- From the activities in Hawaii, we know that past igneous rocks must have been formed by the cooling and solidification of magma.
- This the tenet of the uniformitarian principle.

To solve this problem, we can use the cosine formula for
calculating the length of the displacement:
c^2 = a^2 + b^2 – 2 a b cos θ
where c is the displacement, a = 3.5 km, b = 4.5 km, and θ
is the angle inside the triangle
Since the geeze turned 40° from west to north, so the
angle inside the triangle must be:
θ = 180 – 40 = 140°
c^2 = 3.5^2 + 4.5^2 – 2 (3.5) (4.5) cos 140
c^2 = 56.63
c = 7.53 km
<span>So the magnitude of the displacement is 7.53 km</span>
The kinetic energy bc the energy is independent of the gravitational acceleration, and it depends only on the speed and mass. So the last answer
Answer:
C. a few days
Explanation:
The evidence that we will have to investigate is the gunshot residue on the body of the suspect. When a person fires a gun there will be a deposition of material from the components of the chemicals present in the gun. This deposit is called gunshot residue and consists of particles of the propellant or explosive primer.
Experimentation has shown that the period of time that is person will test possible for gunshot residue is 5.27 days.
