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

Firdavs [7]

Answer:

speed of the spaceship is 0.495251 c

Time T = 1.4982 hr

Explanation:

given data

length L1 = 1600 m

length L2 = 1390 m

to find out

speed of the spaceship and time

solution

we know here

L2 = L1 × $\sqrt{1 - V^{2} }$

so we find V by put L1 and L2

1390 = 1600 × $\sqrt{1 - V^{2} }$

V = 0.495251 c

speed of the spaceship is 0.495251 c

and

we know T1 = 1.95 hr

so we find T2

T1 = T2 $\sqrt{1 - v^{2} }$

put here V and T1 so we get T2

1.95 = T2 $\sqrt{1 - 0.495251^{2} }$

Time T = 1.4982 hr

Power is the rate of work that is done per time. Work is calculated from the product of force and the displacement. So, by using the definition of power and work, we can relate power with force, displacement and the time. We do as follows:

Power = Work / time
Power = Force x displacement / time
Power = 21 N (9 m) / 3 s
Power = 63 J /s = 63 W

The sun generates both mechanical and electromagnetic waves. Which statement about those waves is true?

Vladimir [108]

Answer: The correct answer for this question is letter (B) The electromagnetic waves reach Earth, while the mechanical waves do not. The sun generates both mechanical and electromagnetic waves. Space, between the sun and the earth is a nearly vacuum. So mechanical wave can not spread out in the vacuum.

Hope this helps!
