Answer:

1.The velocity of fluid

2.Fluid properties.

3.Projected area of object(geometry of the object).

Explanation:

Drag force:

Drag force is a frictional force which offered by fluid when a object is moving in it.Drag force try to oppose the motion of object when object is moving in a medium.

Drag force given as

$F_D=\dfrac{1}{2}\rho\ A\ V^2$

So we can say that drag force depends on following properties

1.The velocity of fluid

2.Fluid properties.

3.Projected area of object(geometry of the object).

Answer:

The weather conditions do not suggest a blizzard. It is explained below.

Explanation:

wind_speed=randi([12 56],24,1);

visibility=randi([1 10],24,1)/10;

storm_data=[wind_speed,visibility];

save stormtrack.dat storm_data -ascii

clear

load stormtrack.dat

fprintf('Below is the storm data from the file stormtrack.dat \n');

disp(stormtrack)

wind_speed=stormtrack(:,1);

visibility=stormtrack(:,2);

L=length(wind_speed);

count=0;

i=0;

while count<4 && i<L

i=i+1;

if wind_speed(i)>=30 && visibility(i)<=0.5

count=count+1;

else

count=0;

end

if count==4

fprintf('The weather conditions suggest a blizzard.\n')

else

fprintf('The weather conditions do not suggest a blizzard.\n')

end

Results:

Below is the storm data from the file stormtrack.dat

Examples of reciprocating motion in daily life

bonufazy [111]

Answer:

Examples of reciprocating motion in daily life are;

1) The needles of a sewing machine

2) Electric powered reciprocating saw blade

3) The motion of a manual tire pump

Explanation:

A reciprocating motion is a motion that consists of motion of a part in an upward and downwards $(\updownarrow)$ or in a backward and forward (↔) direction repetitively

Examples of reciprocating motion in daily life includes the reciprocating motion of the needles of a sewing machine and the reciprocating motion of the reciprocating saw and the motion of a manual tire pump

In a sewing machine, a crank shaft in between a wheel and the needle transforms the rotary motion of the wheel into reciprocating motion of the needle.

The should be no concerns about the space immediately below the tanks because there will be no damage to anything if any peril causes the tank to falls.

<h3>What are potential hazards?</h3>

Potential hazards refers to the active source for potential damage on a building, structure etc

It is important we know that the storage tanks are placed on a platform next to the building at the second-floor level but nothing beneath the tanks stands.

Hence, there should be no concerns about the space immediately below the tanks because there will be no damage to anything if any peril causes the tank to falls.
