A fixed container containing an ideal gas is heated. The pressure of the gas increases because:_________

According to the National Electric Code (NEC) section 426.20(A), an embedded deicing unit of the resistance type shall not exceed 120 watts/ft2 of the heated area.

This limits the amount of power that an embedded deicing unit of the resistance type can use to melt snow and ice on a surface. This ensures that the unit does not overheat or create a fire hazard.

It's important to note that this limit applies to the total power used by the embedded deicing unit and not just the heating element. Other factors like the type of material, the environment, and the design can also affect the performance and safety of the deicing unit.

It's recommended to consult with local code officials or a licensed professional to determine the specific requirements and limitations that apply to your project.

The required number of circles is 83.33.

Scale ratio, S = 10:1

Maximum discharge of reservoir, Q = 200 m³/s

Maximum discharge of model, q = 0.1 m³/s

Time measured by model, t = 1 hour

Time measured in a circle, T = ?

We can use the following equation to relate the discharges, lengths, areas, and times of the reservoir and the model:

Q₁/Q₂ = (L₁/L₂)² × (A₁/A₂) × (t₁/t₂)

where Q₁ and Q₂ are the discharges, L₁ and L₂ are the lengths, A₁ and A₂ are the areas, and t₁ and t₂ are the times.

In the given problem:

L₁/L₂ = 10/1 (scale ratio)

A₁/A₂ = 1 (as the shapes are similar)

Q₁ = 200 m³/s

Q₂ = 0.1 m³/s

t₁ = 1 hour

Therefore,

200/0.1 = (10/1)² × 1 × (1/t₂)

Simplifying the equation, we get:

2000 = 100 × (1/t₂)

Solving for t₂, we find:

t₂ = 1/2000 hour

Now, we need to find out how many hours are in a circle. In a circle, the time period is 24 hours, i.e., T = 24 hours.

So, the number of circles in 1 hour is 1/24. Therefore, the number of circles in 1/2000 hour is:

(1/24) × (1/(1/2000)) = (1/24) × (2000) = 83.33

Thus, 1 hour is approximately equal to 83.33 circles.

Hence, the required number of circles is approximately 83.33.

Answer:

I mean they have the same amount of velocity

Explanation:

F = k |q1| |q2| / r^2

k = 9 * 10^9

q1 = - 2.5 C

q2 = 2 C

r = 100

r^2 = (10^2)^2 = 10^4

F = (9*10^9) * ( 2.5 ) ( 2) / ( 100)^2

F = 45* 10^9 / 10^4

F = 45 * 10^9 * 10 ^ -4 = 45 * 10^5 N

F = 45 * 10 ^ 5 N

Answer:

his acceleration rate is -0.00186 m/s²

Explanation:

Given;

initial position of the car, x₀ = 100 miles = 160, 900 m ( 1 mile = 1609 m)

time of motion, t₀ = 60 minutes = 60 mins x 60 s = 3,600 s

final position of the car, x₁ = 150 miles = 241,350 m

time of motion, t₁ = 100 minutes = 100 mins x 60 s = 6,000 s

The initial velocity is calculated as;

u = 160, 900 m / 3,600 s

u = 44.694 m/s

The final velocity is calculated as;

v = 241,350 m / 6,000 s

v = 40.225 m/s

The acceleration is calculated as;

\(a = \frac{\Delta V}{\Delta t} = \frac{v- u}{t_1 - t_ 0} = \frac{40.225 - 44.694}{6000-3600} = -0.00186 \ m/s^2\\\\\)

Therefore, his acceleration rate is -0.00186 m/s²

Answer:

Yes, when dealing with electricity as long as there is an input source there is always built up energy waiting to be used also known as kinetic energy. The fan is not spinning but if it were turned on it would spin instantaneously.

The current delivered by the battery in the circuit is \( \frac{V}{R_{\text{eq}}} \), where \( V \) is the voltage of the battery and \( R_{\text{eq}} \) is the equivalent resistance of the circuit.

To find the equivalent resistance, we can use the formula for resistors in series. Since all the resistors have the same resistance \( r = 820 \, \Omega \), the equivalent resistance can be calculated as \( R_{\text{eq}} = nr \), where \( n \) is the number of resistors connected in series.

Resistors connected in series add up to create an equivalent resistance that is the sum of individual resistances. In this circuit, since all resistors have the same resistance, we can simply multiply the resistance by the number of resistors.

Equivalent resistance represents the total resistance of a circuit when multiple resistors are combined. It determines how much current will flow through the circuit when a voltage is applied.

Answer:

I = 0.75 A

Explanation:

The question is not to calculate the resistance, but to calculate the current. (The resistance is already given by the value of 2 Ohm).

U = I * R

I = U / R

with U = 1.5 V and R = 2 Ohm

I = 1.5 / 2

I = 0.75 A

Answer:

The total kinetic energy of the car can be divided into two parts: translational kinetic energy, due to the car's motion as a whole, and rotational kinetic energy, due to the rotation of the wheels about their axles.

The translational kinetic energy of the car is given by:

KE_translational = (1/2)mv^2

where m is the mass of the car and v is its speed.

The rotational kinetic energy of each wheel can be calculated as:

KE_rotational = (1/2)Iω^2

where I is the moment of inertia of a wheel and ω is its angular velocity.

The moment of inertia of a uniform disk is given by:

I = (1/2)mr^2

where m is the mass of the disk and r is its radius.

The mass of each wheel is given as 12 kg, so the moment of inertia of each wheel is:

I = (1/2)(12 kg)(0.5 m)^2 = 1.5 kg·m^2

Assuming that the wheels are rolling without slipping, the angular velocity of each wheel can be related to the speed of the car by:

v = rω

where r is the radius of the wheel.

Solving for ω, we get:

ω = v/r

Substituting this expression into the equation for KE_rotational, we get:

KE_rotational = (1/2)(1.5 kg·m^2)(v/r)^2

Simplifying, we get:

KE_rotational = (3/8)mv^2

So the rotational kinetic energy of each wheel is (3/8) of the translational kinetic energy of the car.

The total rotational kinetic energy of all four wheels is therefore:

KE_total_rotational = 4 KE_rotational = (3/2)mv^2

The total kinetic energy of the car is:

KE_total = KE_translational + KE_total_rotational = (5/2)mv^2

So the fraction of the total kinetic energy of the car that is due to the rotation of the wheels about their axles is:

KE_total_rotational / KE_total = (3/5) = 0.6

Therefore, 60% of the car's total kinetic energy is due to the rotation of the wheels about their axles.

Answer:

electromagnetic waves can travel through a vacuum where as mechanical waves have to have a medium to travel

Explanation:

Answer: A is the correct answer :)

Explanation:

Explanation:

The potential energy of an object has the following formula

         Potential energy = mgh

      where m = mass of the object

                   g = acceleration due to gravity

                   h = height of the object

This means that the potential energy of an object depends upon its mass, acceleration due to gravity, and height.

In the given situation we have a bucket full of water. If the mass and acceleration due to gravity are not changed, the only way the potential energy can be decreased is by reducing the height of the bucket full of water.

This can be done by: -

         (i) Lifting the bucket full of water in such a way that you

             decrease its height as compared to the bench.

        (ii) Put the bucket full of water on a stool whose height is

            lower than the bench.

Answer:

1.By decreasing it's contents- this decreases the weight of the bucket thus decreasing the potential energy of the bucket.

2.By decreasing the height of the bench we have decreased the amount of potential energy stored in the bucket

The influence of salinity, temperature and physiological development on habitat choice by juvenile salmon is poorly understood.

Answer:

Below

Explanation:

It is likely that changes in salinity can affect the population of juvenile salmon in a number of ways. For example, if the salinity of the water increases, it can lead to increased stress on the fish and make it more difficult for them to survive.

This can lead to a decrease in the population of juvenile salmon. On the other hand, if the salinity decreases, it can make it easier for the fish to survive and potentially lead to an increase in the population.

It is important to note, however, that the exact response of the population to changes in salinity will depend on a variety of factors, such as the species of salmon, the specific environment in which they are living, and the magnitude of the change in salinity.

Force of the ball against the bat

Explanation:

Newton's third law of motion states that for every action, there is an equal and opposite reaction. When a player hits a ball with a bat, the force the player exerted on the ball through the bat gave the ball a push force in the forward direction. This is an action force. Now that an action has been initiated, there must be a reaction according to Newton's third law of motion. The magnitude of the force on the ball equals the magnitude of the force on the bat. The direction of the force on the ball is opposite to the direction of the force on the ball. The ball will give the bat an equal and opposite force trying to push the bat backward by resisting the impact of the bat. This is the reaction. The ball will only move if the applied force is able to overcome the resisting force by the bat

Where;

The normal force is less than the 10 N

Since we are given a box weight that is  10 N  tilted at 45⁰, so the formula we refer  from the figure to for calculating the normal force is:

N=mg⋅cos θ , where mg is the weight of the  box and θ is the angle at which the box is shifted.

The flatter the incline to be,  the normal force becomes greater. The littler an angle gets to be making the greater the esteem of cosine gets to be, and along these lines the greater the normal force becomes.

So, we get that the normal force will be

= 10 cos 45 (Since the value of mg  is 10 N and θ = 45⁰)
