how much heat transfer (in j) occurs from a system if its internal energy decreased by 300 j while it was doing 16.0 j of work? (enter the magnitude.)

Answers

Answer 1

The system released 134 J of energy into the surrounding while doing 16 J of work.

What is energy ?

The ability to exert a force that causes an item to move is what is meant by the definition of energy as the "power to accomplish work."

We use thermodynamics principles in this situation. There are already obtained relationships for intense properties like internal energy (U), heat transfer (Q), and work (W) that were based on differential equations. The formula is

ΔU = Q + W

But since these factors depend on their signs, we must remember to take them into account. Van Ness, Smith, and Abbott assert that declining has a negative sign convention. If work is being done ON the system, the sign is positive; however, if work is being done BY the system, the sign is negative. in this instance,

ΔU = -150 J

W = -16 J

Then , we can determine Q as follows

- 150 J = Q - 16 J

Q = - 134 J

Thus 134 J of heat of released by the system into the surroundings.

Answers

An outdoor thermometer ~sterl1l temperature of 40 f. five minutes after it is brought into a room where the temperature is 70 f. the thermometer registers 60 of. In 8.15 min it will register 65 f.

The physical concept of temperature indicates in numerical form how hot or cold something is. A thermometer is used to determine temperature. Thermometers are calibrated using a variety of temperature scales, which historically defined distinct reference points and thermometric substances. The most popular scales are the Celsius scale, sometimes known as centigrade, with the unit symbol °C, the Fahrenheit scale (°F), and the Kelvin scale (K), with the latter being mostly used for scientific purposes. One of the seven base units in the International System of Units is the kelvin (SI). The lowest temperature on the thermodynamic temperature scale is absolute zero, or 0 kelvin, or 273.15 °C. The third law of thermodynamics acknowledges that it cannot actually be reached experimentally but can only be very closely approached. At that temperature, it would be difficult to produce heat from a body. All areas of natural science, including physics, chemistry, Earth science, astronomy, biology, ecology, material science, metallurgy, mechanical engineering, geography, and most aspects of daily life, depend on temperature. These fields include medicine, biology, ecology, and most other branches of science.

xif 54 j of work is needed to stretch a spring from 10 cm to 16 cm and another 90 j is needed to stretch it from 16 cm to 22 cm, what is the natural length (in cm) of the spring? cm

Answers

the natural length (in cm) of the spring is 4 cm

Calculation :

Let a = natural length of string from given data

54 = k/2(16-a)² - k/2(10-a)²

108 = k[256 + a² - 32a - 100 - a² + 200]

108 = k[156 - 12a]

9 = k[39 - 3a]   ------ 1

90 = k/2(22-a)² - k/2(16-a)²

90 = k(114 - 6a)

15 = k(19 - a) --------2

solving eqn 1 and 2

15/9 = (19k - ka)/(13k - ka)

15/9 = (19- a) / (13 - a)

24 = 6a

a = 4 cm

the natural length (in cm) of the spring is 4 cm.

In a game of tug-of-war, two teams pull on opposite directions of a rope and there are two
important forces. If Newton's 3rd Law says the forces are equal, explain how it is possible to
win tug-of-war.

Answers

This phenomenon of motion in physics can be explained in the following manner,

In a tug-of-war the rope is pulled by the two competing teams simultaneously, each using an equal amount of force. The rope is pulled with equal force by both teams thanks to Newton's third law. If one team pushes harder, the other team will follow suit.

The power with which the teams press the ground determines whether one team wins or loses. The team that pushes the floor harder gets pushed back with identical intensity by the ground, causing them to stand up straight without losing their equilibrium.

As a result, the power by which the team pushes the floor determines who wins and who loses.

At point A
The height = h₁ = r

The height = h₂ = 0
The velocity = v₂

(0.5 × m × 0²) + (m × g × r) = (0.5 × m × v₂²) + (m × g × 0)

Answers

Yes, it is possible for a particle to be found within the barrier while undergoing tunneling.

This phenomenon is known as quantum tunneling. Quantum tunneling occurs when a particle tunnels through a barrier that is normally too high to be crossed by the particle's kinetic energy. This occurs due to the wave-like nature of particles, which allows them to go through barriers that are otherwise impenetrable.

The wave-like nature of particles allows them to penetrate the barrier, often with a probability greater than zero.

Electromagnetic radiation that can be seen by the human eye is known as light or visible light. Typically, visible light is characterized as having wavelengths between 400 and 700 nanometers (nm), or frequencies between 750 and 420 terahertz, which fall between the longer-wavelength infrared and the shorter-wavelength ultraviolet (with shorter wavelengths). The term "light" in physics can be used to more broadly describe electromagnetic radiation of any wavelength, whether or not it is visible. Gamma rays, X-rays, microwaves, and radio waves are all forms of light in this sense. Intensity, illumination, propagation direction, frequency or wavelength spectrum, and polarization are the four main characteristics of light. One of the fundamental constants of nature is its speed in a vacuum, which is 299 792 458 meters per second (m/s). The wavelength of EMR affects how it behaves. While lower frequencies have longer wavelengths, higher frequencies have shorter ones.

The differential gravitational force that one body exerts on opposite sides of another body is called gravitational torque.

Gravitational torque is a measure of the rotational force exerted by a gravitational field on an object. It is equal to the product of the gravitational force and the lever arm (the distance between the point of application of the force and the axis of rotation).

For example, consider a satellite orbiting a planet. The satellite experiences a gravitational force from the planet, which acts to pull it toward the planet. However, this gravitational force is not uniform over the surface of the satellite.

The side of the satellite closest to the planet experiences a stronger gravitational force than the side furthest from the planet. This differential gravitational force creates a gravitational torque on the satellite, which causes it to rotate about its axis.

What is an example of resistance?

Consider the scenario of a person navigating a busy market and encountering difficulty moving from one business to another to better understand resistance. Undoubtedly, this circumstance is comparable to a particle trying to pass through a wire.

What factors affect resistance?

An electrical conductor's resistance is determined by its length, resistivity, and cross-sectional area. The relationship between conductance and resistivity must be understood; the more conductive that anything is, the less resisting it is.

How does changing the frequency affect the wave speed

Answers

Answer:

Explanation:

Changing the frequency or amplitude of the waves will not change the wave speed, since those are not changes to the properties of the medium.

Answer:

Changing the frequency or amplitude of the waves will not change the wave speed

Explanation:

a 1.5 kg block is sliding on a frictionless surface with a speed of 12 m/s when it crashes into a horizontal spring. the spring has a spring contstant of 2100 n/m. how far will the spring be compressed wehn the box's speed has been reduced to exactly half its speed?

Answers

The spring's compressed length before halting frictionless  is therefore 0.40m.

(m2) (s–1) (s–1)

2 N kg m s2 (kg m-1) Take a test. 5. Scalars: mass, distance, and the labour required to extend the spring out of its equilibrium position are stored as elastic potential energy; vectors: displacement, velocity, acceleration, and force; The work required to extend the spring away from equilibrium is equal to the change in kinetic energy of the box. The spring is extended until the box stops moving; hence, the box's final kinetic energy is zero. The elastic potential energy used to compress the spring can be equated to the initial kinetic energy of the box to find the expression to compute the compressed distance using the law of conservation of energy frictionless.
