N a circuit, when the two conductors leading from the power source touch metal-to-metal, this is called a _____ circuit

Answers

Answer 1

In a circuit, when the two conductors leading from the power source touch metal-to-metal, this is called a short circuit

Types of short circuit

There are two types of short circuits, short-to-power and short-to-ground, where electricity takes an unintentional shortcut without going through the intended sensor or actuator.

Short to ground - When there is a short to ground, it refers to the current flowing from the circuit to the car body. Wires can tear and strip their insulation, contacting the body or engine. A short path to ground can result in blown fuses, malfunctioning lights or motors, or “missing” sensors. For example, a scuffed wire might be short to ground, which could cause the headlight fuse to blow, protecting the circuit from overheating, but killing the headlights. Short power - In a wire harness, with many circuits in close proximity, there is a possibility of a short power fault. In this case, wires that are wound or cut can interconnect with each other, allowing current to flow where it is not intended. For example, someone installing an aftermarket device might push a screw through a wire harness, accidentally puncturing and "connecting" some of the wires. Turning on the headlights might send current into the horn, or hitting the brakes might illuminate the taillights.

A standing wave is set up in a pipe with both ends open. The frequency of its first harmonic is 300 Hz. What is the length of the pipe? Take the speed of sound to be 340 m s–1. Give your answer in meters

Answers

When the frequency of a standing wave set up in a pipe (with both ends open) first harmonic is 300 Hz, the length of pipe is 0.567 metres.

Therefore the answer is 0.567 m.

The speed of sound in air is approximately 340 m/s, and the wavelength of the first harmonic of a standing wave in an open pipe is twice the length of the pipe. Therefore, if the frequency of the first harmonic is 300 Hz, the wavelength can be calculated as:

wavelength = speed of sound / frequency

wavelength = (340 m/s) / (300 Hz)

The length of the pipe can be calculated as half the wavelength:

L = wavelength/2

L = (340 m/s) / (2×300 Hz)

L ≈ 0.567 m

So the length of the pipe is 0.68 m

How will you explain the effect of the absorption and release of heat on the kinetic energy and arrangement of particles of matter?

Answers

According to the kinetic theory of matter, changes in heat energy allow for phase transitions between solids, liquids, and gases.

When something is heated, the particles inside move faster and have more energy. When an object warms up, its atoms and molecules gain kinetic energy. When something is heated, its constituent atoms or molecules accelerate in their motion. Matter's kinetic energy can be quickly and easily increased.

When an object warms up, its atoms and molecules gain kinetic energy. The atomic or molecular motions of matter increase with temperature. Lifting a particle's kinetic energy is a breeze. When a substance absorbs heat, the inter-particle bonds in it weaken and break, resulting in a phase transition. If the particles aren't moving faster, there can't be any more heat.

If Deon runs directly into Chuck, who has a total mass of 120 kilograms and is standing still, what is the momentum of the Deon-Chuck system after the collision? Assume momentum is conserved.

Answers

The law of conservation of momentum states that the momentum of a system is equal and conserved before and after collision. Therefore, the final momentum of the system is 513 kgm/s.

What is the law of conservation of momentum?

The law of conservation of momentum states that, for two or more bodies which are present in an isolated system that are acting upon each other, their total momentum remains constant in the system unless an external force is applied on them. The expression for conservation of momentum is:

m₁ u₁ + m₂u₂ = m₁v₁ + m₂v₂

where, m₁ = mass of one object,

m₂ = mass of another object,

u₁ and u₂ are the initial velocities of objects,

v₁ and v₂ are the final velocities of objects.

Here, m₁ = 95kg, m₂ = 120kg

u₁ = 5.4m/s, u₂ = 0m/s (at rest)

m₁ u₁ + m₂u₂ = m₁v₁ + m₂v₂

95 × 5.4 + 120 × 0 = 95 × v₁ + 120 × v₂

513 + 0 = 95 × v₁ + 120 × v₂

Momentum before collision = Momentum after collision

Therefore, the momentum after collision is 513 kgm/s.

With no friction, you can use the relationship between potential and kinetic energy to predict the speed of the car at the bottom of this hill from its starting height. To do this start by setting the kinetic and potential energy equations equal to one another. K= U

1/2mv^2 = mhm


a. Use algebra to solver for the speed. V=


b. With the no friction, does the final speed depend on the mass of the car?


c. With no friction, does the final speed depend on the steepness of the hill?


d. What is the final speed of the car if the height of the hill is 55 cm (. 55m)?

Answers

A) Using algebra, the required speed V=(2gh)1/2

B)  With the no friction, the final speed does not  depend on the mass of the car.

C) With no friction, the final speed does depend on the steepness of the hill.

D) The final speed of the car if the height of the hill is 55 cm is 3.569 m/s.

Given that there is no friction considered. Thus, the total energy of the system can be considered as conserved.

Thus, sum of kinetic and potential energy will be constant.

K = U

mu 2   = mgh ......................................(1)

m = mass of object

v = speed of object

g = acceleration due to gravity = 9.8 m/s2

h = height of object with respect to a reference position

Thus for an object at a height from ground, will have its potential energy converted to kinetic energy during it's descent.

(A) from (1)

mv2 = 2mgh

Thus,   v2 = 2gh

            v = (2gh)1/2

this, is the velocity of an object from conservation of energy.

(B) with no friction, the enrgy is taken to be conserved. from the answer of (A), we know,

v = (2gh)1/2.

clearly this equation doesn't depend on mass.

thus, final speed doesn't depend on the mass.

(C) Given height of hill , h = 65cm = 0.65 m

from (1),    v = (2gh)1/2.

the potential energy of car at the hill top = mgh

this potential energy gets entirely converted to kinetic energy at the bottom of hill due to conservation of energy. Thus

v = (2 x 9.8 x 0.65)1/2

   =  3.569 m/s

Thus, the final velocity of the car is 3.569 m/s

Answers

Due to the surface makeup and the product that spilled, Downhill/Downwind is the direction most hazardous materials will spread based on their viscosity.

The viscosity of a fluid (liquid or gas) is its resistance to a change in form or movement of neighbouring sections relative to one another. Viscosity signifies resistance to flow. The SI unit is poiseiulle (PI).

It relates to the colloquial sense of "thickness" in liquids: syrup, for example, has a higher viscosity than water. The strength of the compensatory force is related to the viscosity of the fluid in a tube with a constant rate of flow.

In general, viscosity is affected by the condition of a fluid, such as temperature, pressure, and rate of deformation. However, in certain circumstances, the reliance on some of these features is minor. The viscosity of a Newtonian fluid, for example, does not vary appreciably with the rate of deformation. Only at very low temperatures is zero viscosity (no resistance to shear stress) observed in superfluids; otherwise, the second law of thermodynamics requires all fluids to have positive viscosity.

A 63.0-kg sprinter starts a race with an acceleration of 3.20 m/s2. If the sprinter from the previous problem accelerates at that rate for 20.0 m, and then maintains that velocity for the remainder of the 100.0-m dash, what will be his time for the race

Answers

At his current velocity the sprinter will complete the 100.0-m dash in 28.53 s.

What is velocity?

Velocity is a vector quantity that describes the rate of change of an object's position. It is a measure of how fast an object is moving and in what direction. Velocity is measured in units of meters per second (m/s) or miles per hour (mph) and is often represented by the symbol "v".

We can use the equations of motion to calculate the time for the sprinter to complete the race.

First, we can use the equation:

v = u + at

to find the final velocity of the sprinter after accelerating for 20.0 m. Here, u is the initial velocity (which is 0 m/s since the sprinter is at rest at the start of the race), a is the acceleration of 3.20 m/s^2, and t is the time it takes for the sprinter to accelerate for 20.0 m.

v = 0 + (3.20 m/s^2)(t)

We know that the sprinter accelerates for 20.0 m, so we can use the equation:

s = ut + 1/2at^2

to find the time t:

20.0 m = (0 m/s)(t) + 1/2(3.20 m/s^2)(t^2)

t^2 = (20.0 m) * 2 / (3.20 m/s^2) = 12.5

t = sqrt(12.5) = 3.53 s

So the time it takes for the sprinter to accelerate for 20.0 m is 3.53 s.

Next, we can use the equation:

v = d/t

to find the time it takes for the sprinter to cover the remaining 80.0 m of the race at his final velocity. Here, d is the remaining distance of 80.0 m and v is the final velocity found before.

t = d/v = 80.0 m / (3.20 m/s) = 25.0 s

So the time it takes for the sprinter to cover the remaining 80.0 m of the race at his final velocity is 25.0 s

So the total time for the race is the sum of the time it takes to accelerate and the time it takes to cover the remaining distance at a constant velocity:

t = 3.53 s + 25.0 s = 28.53 s

Hence, at his current velocity the sprinter will complete the 100.0-m dash in 28.53 s.

A nonsense mutation is also known as base substitution which results in a stop codon in such a position from where there was not one before, which causes the premature termination of protein synthesis and, more than likely, a complete loss of function in the finished protein.

Simply put, molecules move more quickly as kinetic energy rises. Nevertheless, molecules change phases when potential energy rises. The molecule changes phases as a result of an increase in potential energy.

In a phase change, matter moves from one state to another either by gaining energy through heat and entering a more energetic state, or by losing energy through heat and entering a state with lower energy.

The energy supplied during phase change is only used to separate the molecules; none of it is used to boost the kinetic energy of the molecules. Therefore, since the molecules' kinetic energy is constant, its temperature won't increase.

How do you think William Blake felt about child labor in London during the Industrial Revolution Both the volume and the surface area for three different cells were measured. These values are listed in the following table. Using data from the table above, select the best explanation for why that cell will be able to eliminate waste most efficiently? Cell 2, since it has the highest ratio of surface area to volume, which facilitates the exchange of materials between a cell and its environment Cell 1, since it has the smallest volume and wilt not produce as much waste as the other cells. Cell 3, since it has the largest surface area, which will enable it to eliminate all of its wastes efficiently. Cell 3, because it is big enough to allow wastes to easily diffuse through the plasma membrane.
