Answers

A knock sensor is used where voltage is created by exerting force on a crystal.

What is a force?

A force is a pushing or pulling that an object feels as a consequence of engaging with another thing. Every time two objects contact, a force is applied to everything in the system. When the interaction is finished, the force is no more sensed by the two objects. Forces are merely interactions; they do not exist in isolation.

what does a sensor do and what are some examples?

A sensor is a tool that collects physical information from its surroundings and transforms it into information that can be used by either a machine or a human to understand. Most sensors (which transform the data into electronic data) are electronic, but some are simpler, such as a glass thermometer that displays visual data.

how much heat (in kj) is required to warm 15.0 g of ice, initially at to steam at . the heat capacity of ice is , and that of steam is .

Answers

The ice must be warmed with 4.719 kJ of heat.

How do you calculate heat to melt ice?Let's have a look at the energy required to melt one kilogramme of ice at absolute zero to create one kilogramme of water at absolute zero. We determine that Q = mLf = (1.0 kg)(334 kJ/kg) = 334 kJ is the energy required to melt a kilogramme of ice using the equation for a change in temperature and the value for water from Table 1.The quantity of heat energy required to transform materials from a solid to a liquid is known as the heat of fusion (melting.)The heat of fusion calculation formula is q = mHf.2090 Joules/kg C is the specific heat of ice.

Given data :

The mass of ice is, m = 10.0 g.The initial temperature is, T = - 10 degree Celsius.The final temperature is, T' = 110.0 degree Celsius.The heat capacity of ice is, c = 2.09 J/g C.The heat capacity of steam is, c' = 2.01 J/g C.

When ice absorbs heat, the conversion takes place from ice to water (liquid) and from the liquid to steam at 110 degree Celsius. So,

The amount of heat absorbed is given as,

Q = m[c(T' - T) + c'T']

Q = 10 [ 2.09 ( 110 - ( -10) + ( 2.01 x 110) ]

Q = 4719 J

Convert in kJ as,

Q = 4719/1000

Q = 4.719 kJ

Thus, we can conclude that the amount of heat required to warm the ice is 4.719 kJ.

According to the socioemotional selectivity theory, recently retired joyce will likely seek familiar social contacts that reinforce all of these except: Joy

What is socioemotional selectivity theory?

The Socio-Emotional Selectivity Theory (SST; developed by psychologist Laura L. Carstensen at Stanford University) is a lifelong motivational theory. According to this theory, as time spans shorten, as usually happens with age, people become increasingly selective and invest more resources in emotionally meaningful goals and activities. Changes in motivation also affect cognitive processing. Aging is associated with a relative preference for positive information over negative information among people who have formed rewarding relationships. This selective narrowing of social interactions maximizes positive emotional experiences and minimizes age-related emotional risks for individuals. According to this theory, older adults systematically strengthen their social networks to ensure that available social partners meet their emotional needs.

This theory also focuses on the types of motivations individuals seek to achieve. Knowledge-related goals cover knowledge acquisition, career planning, building new social relationships, and other endeavors that will yield results in the future. Emotion-related goals are aimed at regulating emotions, seeking emotionally satisfying interactions with social partners, and other pursuits whose benefits are currently realizable.

Answers

Assuming a wavelength of 500 nm for light in air, the minimum film thickness required is 83.9 nm.

How do you calculate destructive interference?

refractive index of polystyrene; η_p = 1.49

Refractive index of fablite; η_f = 2.409

The wavelength of light in air is 500nm.

To answer this question, we know that light is first reflected twice.

Once from the top coating layer and once from the contact between the coating and the polystyrene material.

The additional path of light in the coating is 2t, but the path difference is 2tp. Therefore, the minimum required film thickness is given by the formula used in destructive interference, namely 2tη_p = λ/2.

t = λ/2 * 1/2η_p

t = λ/(4η_p)

t = 500/(4 * 1.49)

t = 83.9 nm

So, assuming a wavelength of 500 nanometers for light in air, the minimum required film thickness is: 83.9 nanometers

q is the amount of charge,

v is the velocity of charge

F is the amount of force

B is the amount of magnetic field and

sinθ is the angle made by the charge with the plane of magnetic field.

Since charge is moving perpendicularly to the field, therefore value of sinθ=1

Now, F=qvBsinθ

Answers

The heat lost by one object is equal to the heat gained by the other.

What is heat?
heat is the energy that moves from one body to another when temperatures are different. Heat flows from the hotter to the colder body when two bodies with various temperatures are brought together. Usually, but not always, this energy transfer results in a rise in the temperature of a colder body and a fall in the temperature of a hotter body. By transitioning from one physical state (as well as phase) to another, such as from a phase from solid to liquid (melting), from the a solid to the a vapour (sublimation), from the a liquid to a vapour (boiling), either from one solid form to another, a substance can absorb heat without increasing in temperature.

This is because of the law of conservation of energy, which states that energy cannot be created or destroyed. As a result, the temperature of both objects will change until they reach the same equilibrium temperature. This is known as the law of thermal equilibrium, which states that the temperature of any two objects in thermal contact will eventually reach the same temperature.

(a) The frictional force acting on the 19 kg mass is 120.45 N.

(b) The largest angle that the incline can have so that the mass does not slide the incline is  39⁰.

What is the frictional force acting on the 19 kg mass?

The frictional force acting on the 19 kg mass is calculated by applying Newton's second law of motion as follows;

F = μFn

where;

μ is the coefficient of static frictionFn is the normal force on the 19 kg mass

The normal force on the 19 kg mass is calculated as follows;

Fn = mg cosθ

where;

θ is the angle of inclination of the planeg is acceleration due to gravity = 9.8 m/s²

F = μmg cosθ

F = 0.81 x 19 x 9.8 x cos(37)

F = 120.45 N

The largest angle that the incline can have so that the mass does not slide the incline is calculated as follows;

the net force on the block must be equal to zero

∑F(net) = 0

parallel force - force of friction = 0

mg sinθ - μmg cosθ = 0

mg sinθ = μmg cosθ

sinθ = = μ cosθ

μ = sinθ/cosθ

μ = tanθ

θ = arc tan(μ)

θ =  arc tan(0.81)

θ = 39⁰

a solid cylinder has a mass of 5 kg and a radius of 30 cm. a torque of 40 nm is applied to the cylinder. what will be its angular acceleration?

Answers

A solid cylinder has a mass of 5 kg and a radius of 30 cm. a torque of 40 Nm is applied to the cylinder, then its angular acceleration 177.77 m/s^2.

Torque is a measure of the force that can cause an object to rotate about an axis. Just as force is what causes an object to accelerate in linear kinematics, torque is what causes an object to acquire angular acceleration. Angular acceleration is a quantitative expression of the change in angular velocity per unit time.

Let T be the torque, I be the Inertia and a be the angular acceleration.

In the angular form of Newton's second law, rotational inertia replaces mass and torque (tau) replaces force. The relationship between angular acceleration and torque is true when an object's rotational inertia is constant.

F​ = ma

T= I x a (1)

and I = 1/2 x M x R^2

I = 1/2 x 5 x (0.3)^2 Kgm^2

According to equation 1

a = T/I

a= 40/0.225 = 177.777 m/s^2.

Therefore, angular acceleration is 177.77 m/s^2.

serenity asks carlos what conditions are needed to observe interference of waves from two sources. which responses are correct? (select all that apply.)

Answers

The sources of the waves must be coherent, which means they emit identical waves with a constant phase difference. The waves should be monochromatic - they should be of a single wavelength.

What is interference of waves ?

In physics, interference is the overall result of two or more wave trains travelling in parallel or converging directions. At each place impacted by many waves, the effect is that of adding the individual wave amplitudes.

Interference comes in two flavours positive interference and destructive interference. Additionally, when wave amplitudes reinforce one another and cause an increase in wave amplitude, constructive interference occurs.

a certain kind of glass has an index of refraction of 1.650 for blue light of wavelength 430 nm and an index of 1.615 for red light of wavelength 680 nm. if a beam containing these two colors is incident at an angle of 30.00° on a piece of this glass, what is the angle between the two beams inside the glass?

Answers

The angle between the two beams inside the glass is 0.38⁰.

What is the angle between the two beams inside the glass?

The angle between the two beams inside the glass is calculated by applying the following formula.

Let the angle of refraction of the red light = θ₁

Let the angle of refraction of the blue light = θ₂

The difference in the angle of refraction of the red light and the blue light is calculated as;

Δθ = θ₁ - θ₂

Δθ = arc sin(sinθ₁ / n₁) - arc sin(sinθ₂/n₂)

where;

n₁ is the refractive index of the red light n₂ is the refractive index of the blue light

Δθ = arc sin(sin30 / 1.615) - arc sin(sin30/1.650)

Δθ =  0.376⁰

Δθ  ≈ 0.38⁰

A proton and an electron are placed in an electric field. Which undergoes the lesser acceleration?.

Answers

An Electron will undergoes the lesser acceleration

What is Proton and Electron ?

An electron is a negatively charged particle of equivalent magnitude to a proton, which is positively charged. Therefore, they will feel the same amount of electric force when exposed to an electric field. As a result, the relationship between acceleration and mass will be inverse. An electron will accelerate more quickly than a proton because an electron has a lower mass.

Due to their opposite polarity, an electron and a proton are attracted to one another by an electrical force of equal strength when they are placed in an electric field. However, because of their opposing charges, the force will act in the opposite direction.
