I think the correct answer would be the first option. Scientific models are used to allow scientists to extrapolate or interpolate data. Or in other words, allow them to predict values without performing more experiments. However, they are obtained by experiments first.

The maker of an automobile advertises that it takes 8 seconds to accelerate from 15 kilometers per hour to 70 kilometers per hou
jeyben [28]

Answer:

The distance the car traveled during the given time is 94.44 m.

Explanation:

Given;

time of motion t = 8 seconds

initial velocity, u = 15 km/hr = 4.167 m/s

final velocity, v = 70 km/hr = 19.444 m/s

The distance traveled by the car during this time is given by;

s = (\frac{u+v}{2} )t\\\\s = (\frac{4.167+19.444}{2} )*8\\\\s = 94.44 \ m

Therefore, the distance the car traveled during the given time is 94.44 m.

Object A has a mass m and a speed v, object B has a mass m/2 and a speed 4v, and object C has a mass 3m and a speed v/3. Rank th
borishaifa [10]
<h2>The rank is : P_B>P_A=P_C .</h2>

We need to rank the objects according to the magnitude of their momentum.

We know momentum ,P = m\times v{ here m is mass and v is velocity }

Momentum of object A , P_A = m v.

Momentum of object B , P_B= \dfrac{m}{2}\times4v=2\ mv.

Momentum of object C  , P_C= 3m\times\dfrac{v}{3}=mv.

Now, we can rank them in order of  their magnitude of momentum .

P_B>P_A=P_C.

Hence, this is the required solution.

How well do you think a model can demonstrate the principles of stratigraphy?
igomit [66]

Stratigraphy is a discipline aimed at identifying layers of sedimentary and/or volcanic rocks, which is mainly based on the principle of superposition.

<h3>What is stratigraphy?</h3>

Stratigraphy refers to the science based on the identification of different layers in sedimentary and/or volcanic rocks.

Stratigraphy as a discipline is mainly cemented on the principle of superposition, which indicates that older layers of sediment are located on the bottom.

Stratigraphy allows us to understand the geological past of a region, which is important in different disciplines such as biogeography.
