Answer:

0° FROM or 180° TO

Explanation:

A course deviation indicator or the CDI may be defined as an avionics tool or instrument that is used in the aircraft navigation which is used to determine an aircraft's lateral position with relation to a course.

While using the VOT service, we should tune the VOT frequency of the VOR receiver. And with the CDI leveled centered, the omnibearing selector or the OBS should read as 0° with the TO/FROM indicator showing 'FROM'. Else the OBS should read as 180° with the TO/FROM indication showing 'TO.'

Answer:

I suppose that this is a problem of rotation with constant angular velocity.

This can be answered with arcs.

Suppose that we have a circle of radius R, and an angle A (A expressed in radians)

The length of that arc will be:

L = R*A

Now, a rotating object that rotates at a constant angular velocity, in a time t moves an angle A.

so if this object is moving in a circle of radius R, in the time t the distance traveled is the same that we found above.

L = R*A

Now, if the object moves away from the axis of rotation, we have that the radius of the circle R increases, then also does the value of L (the distance traveled in the time t)

Then, when the object moves away from the axis of rotation, in the same time t, the distance traveled will be higher, which means tath the tangential velocty increased (regardless the fact that the angular velocity is constant)

Answer:

2.1 m/s

Explanation:

The following data were obtained from the question:

Initial velocity (u) = 7 m/s

Time (t) = 0.50 s

Final velocity (v) =?

Since the is thrown upward, it means that the stone is going against gravity. Thus, the value of the acceleration due to gravity will be negative i.e – 9.8 m/s²

Thus, we can obtain the velocity of the stone after 0.50 s as follow:

Initial velocity (u) = 7 m/s

Time (t) = 0.50 s

Acceleration due to gravity (g) = – 9.8 m/s²

Final velocity (v) =?

v = u + gt

v = 7 + (– 9.8 × 0.5)

v = 7 – 4.9

v = 2.1 m/s

Therefore the velocity of the stone after 0.5 s is 2.1 m/s.

Explanation:

moment is an expression involving the product of a distance and physical quantities.

-the size of force applied.

-the perpendicular distance from the pivot to the line of action of the force

Explanation:

Acceleration is change in velocity over change in time.

a = Δv / Δt

a = (-6.8 m/s − (-3.0 m/s)) / (33 min × 60 s/min)

a = (-3.8 m/s) / (1980 s)

a = -0.0019 m/s²

Answer:

0.69 g/cm^3

Explanation:

Given that a small beaker has 50 mL of water in it. A small frog with a mass of 20 grams is dropped into the beaker. The water level rises to 79mL.

The volume of the frog will be:

79 - 50 = 29mL

Convert it to litre by dividing it by 1000

29/1000 = 0.029 L

Since 1L = 1000 cm^3

Convert it to cm^3 by multiplying it by 1000

0.029 × 1000 = 29 cm^3

Density = mass/volume

Substitute the mass and volume into the formula

Density = 20/29

Density = 0.6896 g/cm3

Therefore, the density of the frog is 0.69 g/cm^3 approximately

Answer:

B

Explanation:

heating increases the temperature, increase in temperature increases number of collisions hence increases pressure,volume still remains because there is no addition

Heating increases the temperature, increase in temperature increases the number of collisions hence increasing pressure, volume still remains because there is no addition

The answer is option B.

Due to the fact the frequency of collisions depends on the temperature, A is virtually now not steady. Instead, A will increase slightly with temperature as the extended kinetic energy of molecules at higher temperatures reasons them to move barely faster and for that reason go through more collisions consistent with unit time.

The extent of the fuel consequently turns large because the temperature of the fuel will increase. As the number of gas particles increases, the frequency of collisions with the partitions of the box ought to grow.

Answer:

0.72 atm

Explanation:

Given that the atmospheric pressure on a mountain is 550 mmHg.

Where 1 atm is equal to 760 mmHg.

To Convert millimetre mercury (mmHg) into atmospheric pressure units (atm) , divide the magnitude of pressure by 760. That is,

Pressure = 550/760

Pressure = 0.724 atm

Therefore, pressure in atm is 0.72 atm in two significant figures

Answer:

80.08 km/h

Explanation:

Given that Black Panther ran 567.6 km to the east in 23 hours

Velocity = distance covered/time

Substitute the distance covered and time into the formula

Velocity = 567.6/23

Velocity = 24.68 km/h

then turned around and ran 221.8 km to the west in 1.2 hours.

Velocity = 221.8/1.2

Velocity = 184.83 km/h

What was his average velocity during the trip in km/h ?

Average velocity = (V + U)/2

Since the two velocity are opposite to each other, the average velocity will be:

Average velocity = (-24.68 + 184.83)/2

Average velocity = 160.15/2

Average velocity = 80.08 km/h

Therefore, his average velocity during the trip is 80.08 km/h

Answer:

Electrical breakdown.

Explanation:

When two conductors are relatively close enough, and have a very large voltage between them, it can lead to a Dielectric breakdown. A dielectric breakdown occurs when an insulator is subjected to a high enough voltage, suddenly becomes an electrical conductor and electric current flows through it. The air between the conductors is the insulator that breaks down, leading to an electrical discharge arc to flow between the two conductors. This electrical breakdown can cause catastrophic failure of electrical equipment, and fire hazards.

Answer:

Inertia.

Explanation:

You are moving with a speed of 1 m/s. You are carrying a tray and the ball is at rest in the tray. You stops and the ball rolls off the tray. Whenever you starts moving with a speed of 1 m/s and when ball is at rest, due to inertia of motion the ball comes in motion. But when you stops, the ball is still in motion due to its inertia.

Hence, due to inertia the ball roll off the tray.

Explicación:

La energía cinética es la energía que posee un cuerpo en virtud de su movimiento. Sea la masa del cuerpo m, su velocidad v.

Energía cinética = 1/2 mv²

Parámetros dados

masa del coche = 500 kg

velocidad = 100 km / h

La velocidad debe estar en m / s según la unidad internacional estándar. Al convertir;

100 km / h = 100 * 1000/3600 m / s

100 km / h = 27,8 m / s

velocidad del cuerpo = 27,8 m / s

Necesario

Energía cinética del coche = 1/2 * 500 * 27,8²

Energía cinética del automóvil = 1/2 * 500 * 771.6

Energía cinética del automóvil = 1/2 * 385,801.28

Energía cinética del automóvil = 192,900.64 Julios

Por lo tanto, la energía cinética del automóvil es 192,900.64 julios.

Answer:

The pulling force F is 200 N

Explanation:

We note that the tension in a rope between two or three blocks is given by the relation;

Where we have;

m₁ → T₁ → m₂ → T₂ → m₃ → F

[tex]T_1 = \dfrac{m_1}{m_1 + m_2 + m_3} \times F[/tex]

[tex]T_2 = \dfrac{m_1 + m_2}{m_1 + m_2 + m_3} \times F[/tex]

m₁ = 2 kg

m₂ = 4 kg

m₃ = 4 kg

T₂ = 120 N

Therefore, by substitution, gives;

2 kg → T₁ → 4 kg → 120 N → 4 kg → F

[tex]120 \ N = \dfrac{2 \ kg + 4 \ kg}{2 \ kg+ 4 \ kg+ 4 \ kg} \times F = \dfrac{6 \ kg}{10 \ kg} \times F[/tex]

F = 120 N × (10 kg)/(6 kg) = 200 N

The pulling force F = 200 N.

Answer:

80 kmh

Explanation:

IDK lol i just divided it by 2 because he drove 80 kilometres in one hour

Answer:

80kmph

Explanation:

speed = d/t

d= distance

t= time

s=160/2

s=80kmph

Given : We have given sets of speed 5.0 m/s, -10.0 m/s, 520.0 cm/s, 18.0 cm/s ,2.0 cm/s .

To Find : Order the given speed from fastest to lowest .

Solution :

First of all we have to convert all the given speed in same units .

We know , 1 m = 100 cm .

Therefore , speed in units cm/s is :

500 cm/s , -1000 cm/s , 520 cm/s , 18 cm/s , 2 cm/s .

We know , that -ve and +ve sign only indicates the direction .

So , comparing their magnitude , we get the order as :

-1000 cm/s , 520 cm/s , 500 cm/s , 18 cm/s , 2 cm/s .

Hence , this is the required solution .

Answer:

a) y = 103.21 m

b) t = 4.6 s

Explanation:

a) The height at which the balls was is given by:

[tex] V_{f}^{2} = V_{0}^{2} - 2g(y_{f} - y_{0}) [/tex]

Where:

[tex]y_{f}[/tex]: is the final height = 0

[tex]y_{0}[/tex]: is the initial height =?

[tex]V_{f}[/tex]: is the final velocity = 45 m/s

[tex]V_{0}[/tex]: is the initial velocity = 0 (is held at rest

g: is the gravity = 9.81 m/s²          

Hence, the height is:

[tex] y_{0} = \frac{V_{f}^{2}}{2g} = \frac{(45 m/s)^{2}}{2*9.81 m/s^{2}} = 103.21 m [/tex]

b) The time before the ball hit the ground is:

[tex] V_{f} = V_{0} - g*t [/tex]

[tex] t = -\frac{V_{f}}{g} = -\frac{- 45 m/s}{9.81 m/s^{2}} = 4.6 s [/tex]

Therefore, 4.6 seconds passed before the ball hit the ground.

I hope it helps you!
