Answer:
D. different isotopes for the same element will always have the same numbers of neutrons.
Explanation:
An isotope is the different variant of an element that has different number of neutron. There are various elements found in nature that have different isotopes.
Number of neutrons present in atom is different for the same element which makes the mass of one isotope different from the another.
Example of such isotope : Isotope of hydrogen are Protium, Deuterium and Tritium.
Different isotopes for the same element will always have the same numbers of neutrons.
The correct statement about isotopes is C. Different isotopes for the same element will always have the same numbers of neutrons. Isotopes are variants of an element that have the same number of protons but different numbers of neutrons. The number of protons in an element determines its atomic number, whereas the sum of protons and neutrons determines its atomic mass. So, while isotopes of the same element have the same number of protons, they can have different numbers of neutrons.

unintended consequences.
Answer:
Refer below for the explanation.
Explanation:
Wave energy impacts the earth by utilizing proposed consequences to impact nature by rising normally on to things. The unintended consequences for instance it could vessels sinking.
Answer:
Motion
Explanation:
the state at which one objects distance from another object is changing is motion
Answer:
Motion
Explanation:
B. 3 g/L in weight
C. 15 m/s2
D. 10 km/hr eastward
Velocity of a moving body is its distance covered by time. Thus, it has the unit of m/s, km/hr. etc. . Therefore, among the given options, 25 m/s and 10 km/hr. are represents a velocity.
Velocity is a physical quantity having both direction and magnitude. Thus, it is a vector quantity and it measures the distance covered by an object per unit time.
Velocity is the ratio of distance to the time, hence its units are m/s, km/hr etc. The rate of change in velocity is called acceleration. Thus acceleration is change in velocity by change in time. Thus, its unit is m/s². Hence, 15 m/s² represents acceleration.
The quantity 3 g/L represents the mass per volume and hence it is density of a substance or can be the concentration of a solution. Thus, options A and D are correct.
