Scientists have found that the long slow sound produced by blue whales is almost consistently a B pitch at 16.0 Hz. The wavelength of this note is 97.5 m. How long would it take for this sound from a blue whale of scientists that is tracking them from 11 km away?

The answer is 7.1 s I just don't know how to get it :/

NO LINKS ISTGGGG

Answers

Answer:

Explanation:

The frequency is 16.0 Hz. That means that 16 of these waves can pass a single point in 1 second. We are given frequency and wavelength. The equation that relates them is

[tex]f=\frac{v}{\lambda}[/tex] where f is frequency, v is velocity, and λ is wavelength. Putting all this together:

[tex]16.0=\frac{v}{97.5}[/tex] and solving for velocity,

v = 16.0(97.5) so

v = 1560 m/s. This wave can travel 1560 meters in a single second!!! Now that we know this velocity, we can use it in a proportion to find our unknown, which is how long, t, it will take to hear this sound 11000m away. (11 km is 11000m):

[tex]\frac{1560m}{1s}=\frac{11000}{t}[/tex] and cross multiply to get

1560t = 11000 so

t = 7.1 seconds

Una niña tira de un carrito por medio de una soga. Si realiza una fuerza de 10 N qué forma un ángulo de 30° con la dirección de desplazamiento. ¿Qué trabajo hace al desplazar 300cm?

Answers

Answer:

El trabajo realizado por la niña es 25.9 J.

Explanation:

El trabajo ue hace la niña viene dado por:

[tex] W = |F|*|d|*cos(\theta) [/tex]    

En donde:

F: es la fuerza realizada = 10 N

A ball of mass .5 kg is dropped from rest from a height of 7 meters. What is its speed just before it hits the ground.

Answers

Answer:

Explanation:

Kinematic equation: Final velocity^2 = Initial velocity^2 + 2*acceleration*displacement

As the ball is dropped from rest, initial velocity = 0.

Acceleration = gravity = 9.8m/s^2

Displacement = 7m

So velocity just before it hits ground

= sqrt( 2*9.8*7)

= 11.71m/s

If you were testing materials to see whether they conduct electricity using a circuit and bulbs, what variable would you be changing?

A. The strength of the battery
B. The number of bulbs
C. The material
D. The time it takes the electricity to complete the circuit

Answers

Answer: C. The material

Explanation:

In order to check whether a material conducts electricity, the first thing to do would be to design a circuit. Connect a positive wire to the batteries and then another wire from the battery to the bulb and then a wire from the bulb as well.

Then bring different materials to test for conductivity by connecting the wires to the material. If the bulb lights then it is a conductor and if it doesn't the material is not a conductor. The material is therefore the changing variable.

A cable car is being pulled up a mountain at 7.5 meters per second. Usually, the car takes 120 seconds to move all the way up the mountain. If its velocity stays constant, how much time will it take the cable car to move 39 meters?

Answers

Answer:

5.2 s

Explanation:

From the question given above, the following data were obtained:

Velocity = 7.5 m/s

Displacement = 39 m up

Time =?

The time taken for the cable cab to get to 39 m can be obtained as follow:

Velocity = Displacement / Time

7.5 = 39 / time

Cross multiply

7.5 × time = 39

Divide both side by 7.5

Time = 39 / 7.5

Time = 5.2 s

Thus, the time taken for the cable cab to get to 39 m up is 5.2 s

Two people are pulling straight down on ropes attached to a wheel. The wheel has a radius of 2.42 m. One person pulls in a clockwise direction with a force of 43.2 N at the end of the wheel, while the other pulls in a counterclockwise direction with a force of 67.8 N only .522 m from the center of the wheel. What is the net torque on the wheel?

Answers

Answer:

69.2 Nm

Explanation:

Since torque, τ = Fd where F = force and d = distance of force from center of wheel.

The torque due to the clockwise force F' = 43.2 N at a distance d' = radius of wheel = 2.42 m (since it is at the end of the wheel) is τ' = F'd' = 43.2 N × 2.42 m = 104.544 Nm. Since this force is counterclockwise, the torque is positive. So, τ' = 104.544 Nm

The torque due to the force F" = 67.8 N at a distance d" = 0.522 m from center of wheel is τ" = F"d" = 67.8 N × 0.522 m = 35.3916 Nm. Since this force is counterclockwise, the torque is negative. So, τ" = -35.3916 Nm

The net torque on the wheel  τ =  τ' +  τ"

= 104.544 Nm + (-35.3916 Nm)

= 104.544 Nm - 35.3916 Nm

= 69.1524 Nm

≅ 69.2 Nm

Una persona pesa 700 N al nivel del mar. ¿Cuándo sube a un avión a

Answers

Answer:

The weight of the person decreases.

Explanation:

Weight of person at sea level = 700 N

height = 10000m

We know that the weight is given by product of mass and the acceleration due to gravity.

The acceleration due to gravity at height is given by

[tex]g' =g\times \left ( \frac{R}{R+h} \right )^2[/tex]

Where, R is the radius of earth and h is the height.

Now, as we go on heights , the acceleration due to gravity decreases, so the weight also decreases as we go on heights.

Which substance would require the most heat to produce a temperature change liquid water or gaseous water vapor?

Answers

Answer:

Notice that for all substances, the heat of vaporization is substantially higher than the heat of fusion. Much more energy is required to change the state from a liquid to a gas than from a solid to a liquid.

Gaseous water would require the most heat to produce a temperature change.

What is meant by intermolecular force ?

Intermolecular force is defined as the force of attraction existing between the neighboring molecules in a container that holds the together.

Here,

Evaporation is the process of conversion of liquid water into gaseous water vapor.

Condensation is the process of conversion of gaseous water vapor into liquid water.

Condensation occurs under higher temperature than that of evaporation. Condensation requires more temperature because the energy for separating the molecules in the gaseous state is comparatively higher. In order to convert the gaseous state into liquid state, it requires a greater intermolecular forces so that the gaseous molecules are brought more closer. The intermolecular force needed for the process of evaporation is lesser when compared to condensation. So, the heat required in evaporation is comparatively less.

Hence,

Gaseous water would require the most heat to produce a temperature change.

According to the question, the train stopped for 3 seconds. So the correct option is D.

What is a motion map?

The one-dimensional plots or graphs are constructed from a position line. It is a horizontal line, along which the position of an object can be indicated, while also indicating its acceleration and velocity.

Arrows are used for marking acceleration and velocity and the direction of these arrows marks the direction of the acceleration or the velocity. The size of the arrow is used to represent the magnitude of the velocity or the acceleration.

Thus, to observe the position, acceleration and velocity of an object in motion, a motion map is used.

Velocity and acceleration vector quantities have magnitude as well as direction. Velocity and acceleration are functions of displacement which is the distance covered in a particular direction. Unlike speed which is a function of distance. Distance just measures the distance covered.

Therefore, according to the question, the correct option is D.

You convince a member of the maintenance crew to mount the support for a simple pendulum at the top of the stack and you suspend a 1.00 kg mass that just misses the ground at its lowest point from the pendulum cord. If the period of the pendulum is 18.7 s, determine the height of the smokestack. 8455.69 Incorrect: Your answer is incorrect. What factors influence the period of a simple pendulum

Answers

Answer:

a. 86.80 m

b. i. The mass of the bob

ii. The length of the pendulum

Explanation:

a. Determine the height of the smokestack.

Using T = 2π√(L/g) where T = period of pendulum = 18.7 s, L = length of pendulum = height of smokestack and g = acceleration due to gravity = 9.8 m/s².

So, making L subject of the formula, we have

T = 2π√(L/g)

T/2π = √(L/g)

squaring both sides, we have

(T/2π)² = L/g

L = (T/2π)²g

Substituting the values of the variables into the equation, we have

L = (T/2π)²g

L = (18.7 s/2π)²(9.8 m/s²)

L = (2.976 s)²(9.8 m/s²)

L = 8.857 s² × 9.8 m/s²

L = 86.796 m

L ≅ 86.80 m

b. What factors influence the period of a simple pendulum

The factors that influence the period of a simple pendulum are

Give your answer as a number.

Answers

Answer:

F = 124 N

Explanation:

Given that,

The mass of bicycle and the rider, m = 12 kg + 50 kg = 62 kg

Acceleration of system, a = 2 m/s²

We need to find the force required to accelerate the system. We know that,

Answers

Answer:

The electromotive force is the voltage measured across the cell terminals when "NO" current is being drawn. That is why electromotive forces are used in Wheatstone Bridges which measure the resistance of an external object.

Just measuring the voltage across a cell does not give one the true EMF because current drawn from the cell will cause a reduction of voltage of I * R where R is the internal resistance of the cell.

Answers

Answer:

Explanation:

Refer to the pic below that I attached as we talk through these answers.

The amplitude is shown as the height from the top of one wave (called the crest) to the midline. If the whole vertical height from crest to trough is 32 cm, then the amplitude is half of that at

A = 16 cm

The wavelength, or λ, is the horizontal distance from crest to crest or trough to trough. Therefore, our wavelength is 48 cm + 48 cm which is

λ = 96 cm

The speed of the wave is the same thing as the velocity of the wave which can be found in the equation

[tex]f=\frac{v}{\lambda}[/tex] where f is the frequency of the wave and lambda is the wavelength. Filling in:
