Answer:
A scientific model is an activity that is aimed at making a specific part or feature easier to understand and define.
Modeling is an essential scientific discipline and is used in the fields of education. Modeling seems to represent empirical objects, phenomena in a logical and objective way.
The oval-shaped world map showing vegetation in green color is a 2D model of the entire earth and demarcates us the world vegetation distribution and growth.
Hence this is a scientific model as its helps in visualizing the land surface of the earth on paper.
Explanation:
Yes because a scientific models doesn't have to be complex, just like this one
Answer:
132.22 N
Explanation:
Weight at the surface of a planet is:
W = GMm / r²
where G is the gravitational constant,
M is the mass of the planet,
m is the mass of the object,
and r is the radius of the planet.
On Earth:
680 N = GMm / r²
If Earth's mass and radius were changed:
W = G (7M) m / (6r)²
W = 7/36 GMm / r²
W = 7/36 (680 N)
W = 132.22 N
The answer should be B - lasts longer.
The number of protons always equals the number of neutrons in all isotopes: false
Different isotopes for the same element always have the same number of protons: True
The number of protons never equals the number of neutrons in an isotope: False (example: He)
Different isotopes for the same element will always have the same numbers of neutrons: false
