Answer:

(1) V=0.03348 gallons

(2) L= 576.813 km .

Explanation:

Write the relation between the density and volume for ethanol.

density ( ρ )= m/V

Volume ( V )= m/ρ .......... (1)

Here, V is the volume of ethanol, m is the mass of ethanol, and is the density of ethanol.

Write the relation between the specific gravity of ethanol and density of water

ρ=γ*ρ(water) ............. (2)

Here, is specific gravity of ethanol and is the density of water.

Determine the volume of ethanol by substituting equation (2) in equation (1)

V=m/γ*ρ(water)

Substitute 100 gm , for m, for , and 1000 kg/m for.

V= $\frac{100*10^{-3} }{0.789*1000}$

V=0.000112674 $m^{3$

Convert m³ to gallons

V= (0.000112674*264.172 )

V=0.03348 gallons

Step 2:

Determine the distance travelled by the special vehicle named “Micro joule” runs with ethanol.

L=C*V .......... (3)

Here, is the rate of consumption of ethanol by Micro joule.

Substitute 10,705 mi/gallons for C and 0.03348 gallons for .

By using eq. 3.

L= 10750*0.03348

L=358.416 mi.

Convert the distance travelled by Micro joule from miles to kilometres

L= (358.416* 1.60934)

L = 576.813 km

Thus, the distance travelled by Micro joule is 576.813 km .

Determine the magnitude of the force F1F1 component acting along the uu axis. Express your answer to three significant figures a

dybincka [34]

The first image below shows force F1 and the axes.

Answer: $(F_{1})_{u}=$ 3.62 kN

Explanation: The second figure below express the parallelogram method to calculate the u component of force F1.

The Parallelogram Method is a method to determine resultant force and is applied as described in the question above.

With the three components, $F_{1},(F_{1})_{u}$ and $(F_{1})_{v}$ and angles, it can be used the Law of Sines, which states:

$\frac{a}{sin\alpha} =\frac{b}{sin\beta} =\frac{c}{sin\theta}$

i.e., there is a relation of proportionality between an angle and its opposite side.

For the triangle below:

$\frac{u}{sin30} =\frac{F_{1}}{sin105}$

$u=F_{1}\frac{sin(30)}{sin(105)}$

$u=7\frac{0.5}{0.966}$

u = 3.62

The magnitude of the component acting along the u-axis is 3.62kN.
