Answer:

The option that identifies why the design sketches in the scenario are inaccurate in the given scenario is;

The scale did not include calculations of ratios to proportions

Explanation:

Given that the reason why Jonah has to redo the design sketches of an office building in Chicago is that the ratios of the parts included in the design sketch are not given in the proportion of the parts in the real-life sizes as the parts in real life sizes are multiples of the ratios given in the design drawings and therefore, without the calculations for the proportions, the design sketches will be ambiguous.

The speed of a vehicle is reduced with a constant acceleration from 72km/h to 18
Radda [10]

Answer:

The correct answer will be "1477.84 N".

Explanation:

Given that,

Mass,

m = 1.6 mg

or,

   = 1600 kg

Initial velocity,

u = 72 km/h

  = 72\times \frac{5}{18} \ m/s

  = 20 \ m/s

Final velocity,

v = 18 km/h

  = 18\times \frac{5}{18}

  = 5 \ m/s

Covered distance,

s = 250 m

By using the below relation, we get

⇒  v^2=u^2+2as

On putting the values, we get

⇒  (5)^2=(20)^2+2\times a\times 250

⇒      a=-0.75 \ m/s^2 (shows the deceleration)

Slope will be given as 1 in 25, then

⇒  Sin \theta=\frac{1}{25}

           \theta=2.3^{\circ}

hence,

As we know,

⇒  \Sigma F=ma

or,

⇒  Braking \ force+350-mgSin\theta=ma

⇒  Braking \ force=ma+mgSin\theta-350

On substituting all the values, we get

⇒                           =1600(0.75+1600\times 9.81 Sin(2.3^{\circ})-350

⇒                           =1477.84 \ N

What is the acceleration of a car that has a velocity of 20 m/s, and
ella [17]

Acceleration of Car = 10 ms⁻²

Explanation:

Step 1:

The basic formula of acceleration is a = (v-u)/t  ms⁻²

where, v- final velocity

            u- initial velocity

             t= time taken

Step 2:

Here v = 70 ms⁻¹

        u = 50  ms⁻¹

         t = 5 s

∴ a = ( 70 - 20)/5

a = 10 ms⁻²
