if a cyclist is travelling a road due east at 12km/h and a wind is blowing from south-west at 5km/h. find the velocity of the wi

slamgirl [31]

Answer:

The velocity of wind with respect to cyclist is $-15.5 \widehat{i} - 3.5 \widehat{j}$ .

Explanation:

speed of cyclist = 12 km/h east

speed of wind = 5 km/h south west

Write the speeds in the vector form

$\overrightarrow{vc} = 12 \widehat{i}\\\\overrightarrow{vw} = - 5 (cos 45 \widehat{i} + sin 45 \widehat{j})\\\\\overrightarrow{vw} =-3.5 \widehat{i} - 3.5 \widehat{j}$

The velocity of wind with respect to cyclist is

$\overrightarrow{vw} =-3.5 \widehat{i} - 3.5 \widehat{j}\overrightarrow{v_(w/c)} = \overrightarrow{vw}-\overrightarrow{vc}\\\\\overrightarrow{v_(w/c)} = - 3.5 \widehat{i} - 3.5 \widehat{j} - 12 \widehat{i}\\\\\overrightarrow{v_(w/c)} =-15.5 \widehat{i} - 3.5 \widehat{j}$

The wall is 500 sq. feet. A gallon of paint covers 160 sq. feet. What is an appropriate conversion factor to help determine how

lana66690 [7]

Answer:

Explanation:

Given

Wall is $500 ft^2$ in area

$160\ ft^2$ requires 1 gallon of paint

so using unitary method

$1\ ft^2 requires \frac{1}{160}$ gallon of paint

$500 ft^2$ wall will require $=500\times \frac{1}{160}$ gallons of paint

$=3.0125\ gallons$

How much heat is needed to raise the temperature of 90g of water by 64oC?

wel

The heat released or absorbed by a process where temperature changes is calculated from the product of the mass of the sample, its heat capacity (4.18 J/g C for water) and the change of the temperature.

Heat = mC(T)
Heat = 90 (4.8) (64) = 27648 J or 27.65 kJ needed

The humber bridge in england has the world's longest single span, 1410 m . calculate the change in length of the steel deck of t

Pepsi [2]

Applicable linear expansion equation:
ΔL = αΔTL
In which
ΔL = change in length, α = Linear expansion coefficient of steel, ΔT = change in temperature, L = original length

Therefore,
ΔL = 12*10^-6*(18.5-(-3))*1410 = 0.36378 m
