you are attempting to create a standing wave with n = 7 in a pipe .50m in length and filled with air. the top of the pipe is open to the ait and the bottom of the pipe is barely submerged in water and thus closed. draw the diagram for this standing wave with the proper nodes and antinodes for this open- closed pipe. what is the frequency?

Answers

Answer 1

The top of the pipe is open to the air and the bottom of the pipe is barely submerged in water and thus closed is 1200.5Hz

[tex]Wavelength =[/tex] λ = [tex]\frac{4L}{7}[/tex]

[tex]Frequency =[/tex] v× 1/λ = 343 ×[tex]\frac{1}{4l/7}[/tex]

[tex]f[/tex] = [tex]\frac{7*343}{4L}[/tex] = [tex]\frac{7*343}{4*0.5}[/tex] = [tex]f = 1200.5Hz[/tex]

In physics, the wavelength is the spatial length of a periodic wave—the distance over which the wave's form repeats. it is the space between consecutive corresponding factors of the same section on the wave, consisting of adjoining crests, troughs, or 0 crossings, and is a characteristic of both visiting waves and standing waves, in addition to other spatial wave patterns. The inverse of the wavelength is known as the spatial frequency. Wavelength is generally particular via the Greek letter lambda (λ). The time period wavelength is likewise once in a while applied to modulated waves, and to the sinusoidal envelopes of modulated waves or waves shaped by means of interference of several sinusoids.

Assuming a sinusoidal wave transferring at a hard and fast wave velocity, the wavelength is inversely proportional to the frequency of the wave: waves with better frequencies have shorter wavelengths, and lower frequencies have longer wavelengths.

hen a boat sails from salt water to fresh water, the boat will float A) lower in the water. B) higher in the water. C) at the same water level.

Answers

A boat that transitions from salt to fresh water will float at a lower level in the water. due to the fact that fresh water is less buoyant than salt water. The boat will therefore flow less in fresh water.

The force that makes things float is known as buoyant force. It is the force applied to a solid object that is partially or completely submerged in a liquid. The pressure differences occurring on the opposing surfaces of an object submerged in a static fluid are what cause buoyancy. Additionally called the buoyant force. It is pretty inevitable that an object's bottom will always be deeper in a fluid than its top, which is why there is a buoyant force.

a volleyball hit into the air has an nitial speed of 10. meters per second. which vector best represents the angle above the horizintal tha the bal should be hit to remain in the air for the greatest amount of time

Answers

The greatest amount of time is going to be achieved when the volleyball is hit with its maximum velocity and that's his maximum vertical component.

In the area has an initial speed of 10 m/s, vector pressure represents the angle above the horizontal, that the ball should be hit to remain there for the greatest amount of time. So the greatest amount of time is going to be achieved when the volleyball is hit with its maximum velocity. And that's his maximum vertical component. And that's going to happen only when the angle is 90° because the entire velocity is on the vertical component. So, this is the vertical component of the velocity that determines the time of flight.When a body is launched in projectile motion making an angle  with the horizontal, its initial velocity has both horizontal and vertical components.The vertical component of the body describes the influence of velocity in displacing the component vertically.

With the advent of modern physics about 100 years later, it was recognized that light can indeed exhibit behavior characteristic of both waves and particles. We have demonstrated that it exhibits the same behavior as extended to molecules .

The amplitude of an oscillating system is the magnitude of change in the oscillating variable with each oscillation. Sound waves in air, for example, are oscillations in atmospheric pressure, and their amplitudes are proportional to the pressure change during one oscillation.

When a wave travels through a medium, it loses energy as it moves. As the distance between the wave and its source grows, it spreads out over a larger and larger area. As the wave spreads through the medium, it loses energy and its amplitude decreases.

In this case, at the point of equilibrium, the cart and the skater will have maximum kinetic energy. By dropping the same bag, the energy is reduced. The amplitude of an oscillating pendulum decreases with time because of friction due to air

a 2100-lb rear-wheel-drive tractor carries a 900-lb load of gravel centered at point l. the tractor starts from rest and accelerates forward at 2.6 ft/s2.

Answers

The net reaction of force on each of fore wheels = 113.5 N

What is force ?

In physics, a force is an effect that can modify the velocity of an object. A mass-containing object can alter its velocity, or as a result of a force, accelerate. One way to think of force is as a push or pull. Due to the fact that it has both a magnitude and a direction, a force is a vector quantity.

Answers

The highlighted artery has two terminal branches are Basilic vein.

The basilic vein travels from the palm of your hand up your arm, passing by the side of your pinky and ulna (a long bone that runs from your elbow to your finger). Due to its proximity to the skin's surface, the basilic vein is regarded as superficial. The inner arm frequently exhibits it. The dorsal venous network's ulnar region is where the basilic vein first appears. The vena mediana cubiti connects to it at the anterior surface just below the elbow as it ascends the basilic vein of the forearm, which goes up the posterior surface of the ulnar side of the forearm.

Answers

His apparent weight will be the greatest when the elevator accelerating upward.

What is accelaration?

acceleration is the rate of to the  change of the velocity of an object with respect by  time.

When a person stand in an elevator moving upwards, he feels heavier because the elevator's floor presses harder on his feet, and the scale will show a higher reading than when the elevator is at rest.

According to Newton's second law

R = mg + ma

where;

R is the reading of the scale = apparent weight of the person

mg is the normal weight of the person

ma is the upward force acting on the person

Therefore, his apparent weight will be the greatest when the elevator is accelerating upward

Saturn’s rings look bright because __________


light from the Sun reflects off the material inthe rings
the material in the rings is hot and createsits own light
light from Saturn reflects off the material inthe rings

Answers

The reason why Saturn's rings appear bright is because sunlight reflects off the ring material.

Because the ice particles in Saturn's rings scatter and reflect sunlight, the rings appear dazzling. Astronomers have long known that when Earth is directly between Saturn and the sun, Saturn's rings reflect sunlight with the greatest intensity. When light reflects off flat, polished surfaces (like a mirror or a pond) in a specific direction, it might appear exceptionally bright. The rings' actual nature becomes clear upon closer inspection. A mix of factors, such as gravity and collisions between the ring particles themselves, account for the rings' appearance of uniformity. Although the planets appear to be perfectly spherical, their spin causes them all to slightly bulge around the equator. The Saturnian ring system is the largest ring system in the Solar System. They are made up of innumerable tiny particles that orbit Saturn and range in size from micrometres to meters. With the exception of a small amount of stony material, the ring particles are virtually exclusively comprised of water ice.

The acceleration due to gravity at a distance r = 2RM from the center of Mars will be 0.933 m/s².

What is acceleration?

In mechanics, acceleration is the rate of change of an object's velocity with respect to time. Acceleration is a vector quantity (as long as it has magnitude and direction). The direction of an object's acceleration is given by the direction of the net force acting on that object. As described by Newton's second law, the magnitude of an object's acceleration is the combined effect of two causes. ) The mass of this object is inversely proportional to the mass of the object, depending on the material the object was made from.

The SI unit of acceleration is meters per second square.
