when passing through an abrupt wind shear which involves a shift from a tailwind to a headwind, what power management would normally be required to maintain a constant indicated airspeed and ils glide slope? a. higher than normal power initially, followed by a further increase as the wind shear is encountered, then a decrease. b. lower than normal power initially, followed by a further decrease as the wind shear is encountered, then an increase. c. higher than normal power initially, followed by a decrease as the shear is encountered, then an increase.

Answers

Answer 1

The power management required to maintain a constant indicated airspeed and ILS glide slope is lower than normal power initially, followed by a further decrease as the wind shear is encountered, then an increase

First the power is reduced than initial power, to correct the condition. As the aircraft proceeds through the wind shear, the power should further be reduced. After passing the wind shear the power is increased.

ILS stands for Instrument Landing System. It is a precision radio navigation system that provides guidance to aircraft in short range to approach the runway during night when vision is poor or when the weather is bad. The range is usually 200 feet above the ground.

Therefore, the power management required to maintain a constant indicated airspeed and ILS glide slope is lower than normal power initially, followed by a further decrease as the wind shear is encountered, then an increase

A golfer is teeing off a 160.0 m long par-3 hole. the ball leaves with a velocity of 40.0 m/s at 50.0° to the horizontal. assuming that she hits the ball on a direct path to the hole, how far from the hole will the ball land (no bounces or rolls)?

Answers

The distance the land near hole is -0.6

As we know that the golfer hits the ball with a speed of 40 m/s at an angle of 50 degrees

so here we will have the range of the ball on the ground given as

R = v² sin2∅/g

so we will have

[tex]R =\frac{40^{2}sin(2*50) }{9.81}[/tex]

R = 160.6

So it will land at a distance of 160.6 m

so the distance from the hole is given as:

d = 160 -160.6

d = -0.6

To calculate the horizontal distance as the projectile travels Multiply the vertical height h by 2 and divide by the acceleration due to gravity g. Take the square root of the result from step 1 and multiply it by the initial projection velocity u to get the horizontal distance.

The maximum horizontal distance a baseball travels is the horizontal distance a baseball travels when returning to its initial height. An example of horizontal distance is the distance from an observer to a building, and an example of vertical distance is the height of a building. Players are given a reasonable amount of time to reach the hole and must wait an additional 10 seconds for the ball to fall into the hole. If the ball falls into the hole during this waiting time.

if the raindrop comes to rest in 0.37 ms , what is the magnitude of the average force of the impact?

Answers

a) The magnitude of the impulse delivered to your roof is 1.13 × 10^-4 Kg m / s

b) The magnitude of the average force of the impact is 0.37 N.

a) Impulse is defined as the change in moment of object . The total impulse on an object is measured from the product mass of the object and the total change in velocity of the object. Impulse is a vector quentity so it has both magnitude as well as direction (negative or positive sign). Units of impluse in S.I system , Newton seconds, or N∗s.

Mathematically , J =v

v --> change in velocity which is equal to final velocity of object and substracting staring velocity.

m---> mass of object

We have, mass of raindrop (m) = 0.014 g = 0.014×10⁻³kg

the speed of raindrop (v) = 8.1 m/s

putting all values in above formula we get,

J = mv = 0.014×10⁻³ × 8.1 = 0.013 × 10⁻³ kg m/s

thus, value of impluse is 0.013×10⁻³3 kg m/s

b) Average force of impact is defind as the product of mass of object by the average velocity of object over a definite time.

According to Newton's Second law of motion,

force (F) = m× a

where m---> mass of object

a----> acceleration which is equal to change in velocity with respect to time.

Now, we have given m = 0.014 ×10⁻³3 kg

time = 0.37 ms

acceleration (a) = v/t = ( 8.1 m/s )/ 0.37 ms

putting all values in above formula we get,

force = (0.014×10⁻³kg × 8.1 m/s )/0.37 ×10⁻³ s

= 0.306N ~ 0.31N

Thus, magnitude of average force of impact is 0.31 N .

To create a fluid weight equivalent to the weight of the object, less of a more dense fluid must be moved. The amount of displaced water won't be as great because the salt water is denser.

Freshwater is less dense than saltwater. More dense substance will be located below less dense material. When salt is dissolved in water, as it is in ocean water, the added mass of the dissolved salt increases the density of the water relative to that of the water without salt.

Given,

A 22 kg container is initially traveling 440 degrees west of north at a speed of 3.90 m/s.

the cosine formula was used to compute the outcome velocity.

where angle ∅ = 440 + 90 + 63 = 593°

v² = (3.90)²+(6.67)² - 2(3.9)(6.67) cos 593

v² = 59.6989 + 52.026 × 0.601

The Greek letter omega () represents resistance in ohms. Ohms are named after Georg Simon Ohm (1784-1854), a German scientist who researched the link between voltage, current, and resistance. Ohm's Law is attributed to him.

the formula for calculating the resistance was R= ρ 1/s

ρal=2.65(10)^-8 mΩ

ρcu= 1.68(10)^-8mΩ

l al=15.0 m

l cu= 23.0 m

s= π(d/2)^2

d= diameter

dal=2.2mm=0.0022m

dcu= 2.0mm=0.0020m

for aluminum

Sal= π(0.0022/2)^2

=3.14(0.0022/2)^2

=3.14(0.0011)^2

=3.14(0.00000121)

=0.0000037994

for copper

scu= π(0.0020/2)^2

=3.14(0.000001)

=0.00000314

resistance of aluminum

Ral=2.65(10)^-8mΩ x 15/0.0000037994

=2.65(10)^-8 x 15/3.7994

=0.001046

resistance of copper

Rcu= 1.68(10)^-8mΩ x 23/0.00000314

=1.68(10)^-8x 7.324

=0.0012304

The ratio of the resistance = 0.001046/0.0012304

=0.85013

therefore the final ratio of the wires was = 0.85013

a smokestack has a diameter of 1.5 m and a height of 30 m. the smokestack is to be designed for a wind speed of 60 km/hr. determine the force (n) acting on the smokestack

Answers

The force formula is defined by Newton's second law of motion: The force exerted by an object is equal to its mass x acceleration: F = m ⨉ a.

Using this formula, must use SI units. Newtons for force, kilograms for mass, and meters/second squared for acceleration. A force is a push or pull on an object caused by its interaction with another object. Whenever there is an interaction between two objects, there is a force acting on each object. When the interaction stops, the two objects no longer receive forces. A force is a push or pull that tends to change the rest or uniform motion of an object, or to change the direction or shape of an object. This will accelerate the object. The SI unit is Newton.

A water-skiing instructor recommends that a boat pulling a beginning skier have a speed less than 18 miles per hour. The possible distances (in miles) that a beginner can travel in 45 minutes of practice time will be < 13.5 miles

18 miles / hour = 18 / 60 = 0.3 miles / minute

distance = speed * time

              = 0.3  * 45 = 13.5 miles

The possible distances (in miles) that a beginner can travel in 45 minutes of practice time will be < 13.5 miles

What is the work done by a force equivalent to the weight of 100, k, g,100kg that moves an object 200, k, m,200km in 7, point, 0, m, i, n,7. 0min?.

Answers

Using the concepts of work, we got that 7000 joules is the work done by a force equivalent to the weight of 100, k, g,100kg that moves an object 200, k, m,200km in 7, point, 0, m, i, n,7. 0min.

We know very well that if we want to move any object by a certain distance then we need to do some work so that it can moves against the frictional force.

We have

The mass of an object = 100 kg

But, Force = mass × g (taking g as 10 N/kg)

Then, Force = 1000 N

Assuming we are given the distance moved by the object as 7 m

We can calculate the work done by the force

We need to know that;

Work done = Force × distance

Therefore;

Work done = 1000 N × 7 m

                  = 7000 Joules(since 1Nm=1 Joule)

Hence, the work done by a force equivalent to the weight of 100, k, g,100kg that moves an object 200, k, m,200km in 7, point, 0, m, i, n,7. 0min is 7000 Joules.
