An object with a mass of 2.0 kg has a force of 5.0 newtons applied to it. What is the resulting acceleration of the object?

The speed of sound in the pipe is 150m/s and that found to be enhanced when air column is 150 mm long.

a two-pronged metal tool used for tuning musical instruments and determining standard pitch that produces a set tone when struck.

ΔL = 150mm => 0.15m = λ/2

               =>  λ = 2 x 0.15 => 0.3 m

The velocity of sound => frequency x wavelength

                                         500hz x 0.3 m  => 150m/s

The length of a tuning fork's prongs determines the pitch it produces. Each fork has a stamp that says the note it makes (for example, A) and the frequency in Hertz (e.g. 440 Hz). Higher pitch (frequency) noises are produced by shorter prongs than by longer prongs.

Explanation:

a) Two other forces that act on thee sled are the weight of the daughter and the drag force

b) The drag force slows down the sled while the weight presses it down.

We know that motion is the result of the action of unbalanced forces. From the Newton's third law, we know that if the forces that are acting on an object are balanced that the object is not going to move from its state of rest.

In this case, we are told that a  father pushes his daughter and son on a sled down a hill. The fact that the led is moving is due to the fact that there are forces that are acting on the sled.

The forces that are acting on the sled apart  from the force that was applied in pushing the sled is the drag force and the weight of the son.

The drag force would determine how fast that the sled would move because it acts in opposition to the forward force and tries to slow down the sled as it is moving. The weight of the son does press the sled downwards.

The density of a fish is controlled by the expansion and contraction of its air sacs while the density of a submarine is controlled by ballast tanks. It was emphasized earlier that buoyant forces does not equal an objects weight but does equal the weight of displaced water.

The three most fundamental characteristics of an object are mass, volume, and density. Volume indicates something's size, mass indicates how heavy it is, and density is calculated as mass divided by volume. Although you deal with mass and volume on a daily basis, the concept of density is less clear-cut and requires careful consideration.

Mass divided by density equals volume; and. Volume times density equals mass. A liquid's density is a gauge of how heavy it is relative to the amount being measured. The liquid that weighs heavier is more dense if you weigh two liquids with similar volumes or amounts.

The relationship between a substance's mass and the amount of space it occupies is known as its density (volume). The density of a substance is determined by the mass, size, and arrangement of its atoms.

Explanation:

The length of the pendulum on the Moon with a period of 1.0 s is approximately 0.0163 meters.

On the Moon, which has one-sixth of Earth's gravity, the length of a pendulum with a period of 1.0 s can be determined using the formula for the period of a pendulum:

T = 2π√(L/g)

Where T is the period, L is the length of the pendulum, and g is the acceleration due to gravity.

Given that the period of the pendulum on the Moon is 1.0 s and the Moon has one-sixth of Earth's gravity, we can substitute these values into the formula and solve for L:

1.0 = 2π√(L/(1/6g))

Simplifying the equation, we can multiply both sides by (1/6g):

\(1.0 * (1/6g) = 2π√L1/6g = 2π√L\)
Now, let's square both sides to get rid of the square root:

\((1/6g)^2 = (2π√L)^21/(6g)^2 = (2π)^2L1/(36g^2) = 4π^2L\)
Simplifying further:

\(L = 1/(4π^2(36g^2))L = 1/(144π^2g^2)L ≈ 0.0163 m\)

Therefore, the length of the pendulum with a period of 1.0 s on the Moon, which has one-sixth of Earth's gravity, is approximately 0.0163 meters.

If the pulling is done parallel to the floor with constant velocity, then the box is in equilibrium. In particular, the weight and normal force cancel, so that

n = 38 N

The friction force is proportional to the normal force by a factor of 0.27, so that

f = 0.27 (38 N) ≈ 10.3 N

and so the answer is D.

Starting from rest on a circular track with a radius of 300 m and a constant tangential acceleration of 0.75 m/s², the car will travel a distance of approximately 0.2119 meters or 21.19 centimeters in 0.75 seconds.

To determine the distance traveled and the time elapsed by the car starting from rest on a circular track with a radius of 300 m and a constant tangential acceleration of 0.75 m/s², we can use the equations of circular motion.

The tangential acceleration is the rate of change of tangential velocity. Since the car starts from rest, its initial tangential velocity is zero (v₀ = 0).

Using the equation:

v = v₀ + at

where v is the final tangential velocity, v₀ is the initial tangential velocity, a is the tangential acceleration, and t is the time, we can solve for v:

v = 0 + (0.75 m/s²) * t

v = 0.75t m/s

The tangential velocity is related to the angular velocity (ω) and the radius (r) of the circular track:

v = ωr

Substituting the values:

0.75t = ω * 300

Since the car starts from rest, the initial angular velocity (ω₀) is zero. So, we have:

ω = ω₀ + αt

ω = 0 + (0.75 m/s²) * t

ω = 0.75t rad/s

We can now substitute the value of ω into the equation:

0.75t = (0.75t) * 300

Simplifying the equation gives:

0.75t = 225t

t = 0.75 seconds

The time elapsed is 0.75 seconds.

To calculate the distance traveled (s), we can use the equation:

s = v₀t + (1/2)at²

Since the initial velocity (v₀) is zero, the equation becomes:

s = (1/2)at²

s = (1/2)(0.75 m/s²)(0.75 s)²

s = (1/2)(0.75 m/s²)(0.5625 s²)

s = 0.2119 meters or approximately 21.19 centimeters

Therefore, the car travels a distance of approximately 0.2119 meters or 21.19 centimeters.

The amount of matter, in kilograms, that must be converted to energy to yield 1.0 gigajoule is 1.11 x 10⁻⁴ kg.

To determine the amount of matter, in kilograms, that must be converted to energy to yield 1.0 gigajoule, we can make use of the famous equation by Einstein, E=mc²,

where E represents energy, m represents mass and c represents the speed of light which is approximately 299,792,458 meters per second.

To calculate the amount of matter that needs to be converted to energy, we need to rearrange the formula to make m the subject:

m = E / c²

where E = 1.0 gigajoule

= 1.0 x 10⁹ Jc

= 299,792,458 m/s

Putting these values into the formula, we have:

m = 1.0 x 10⁹ J / (299,792,458 m/s)²

= 1.0 x 10⁹ J / 8.987551787 × 10¹⁶ m²/s²

= 1.112 x 10⁻⁷ kg

Since the answer is in kilograms, we can express it in scientific notation as 1.112 x 10⁻⁴ kg, or rounded off to three significant figures as 1.11 x 10⁻⁴ kg. Therefore, the amount of matter, in kilograms, that must be converted to energy to yield 1.0 gigajoule is 1.11 x 10⁻⁴ kg.

What does a hurricane mean in simple terms?

A hurricane is defined as a tropical storm with sustained winds of 74 mph or more. A storm's eye typically measures 20 to 30 miles in width and can reach distances of 400 miles. Storms may be dangerous because of their heavy downpours, strong gusts, and storm surges.

Where do storms usually begin?

Near the tropics, in the Caribbean, or in the waters around the Cape Verdean islands of West Africa, hurricanes start to form. Surface water that is relatively warm quickly evaporates before condensing to create clouds in the sky.

The color of visible light that would have the least energy is red. On the other hand, the color of visible light that would have the most energy is violet.

This is because red light has the longest wavelength and the lowest frequency out of all the colors in the visible spectrum. Violet light has the shortest wavelength and the highest frequency out of all the colors in the visible spectrum.

This relationship between wavelength, frequency, and energy can be explained by the relationship between electromagnetic waves and energy. All electromagnetic waves, including visible light, have a certain amount of energy that is proportional to their frequency. The higher the frequency, the more energy the wave has.

This relationship can also be seen in the electromagnetic spectrum, where higher energy waves (such as X-rays and gamma rays) have shorter wavelengths and higher frequencies, while lower energy waves (such as radio waves) have longer wavelengths and lower frequencies.
