An AC non motor-generator arc welder on an individual circuit has a nameplate primary current of 100A and a duty cycle of 70%. The branch circuit conductors must be a minimum size ___ AWG THHN copper.

Answer:

D. Velocity

Explanation:

It is velocity because inertia doesn't have any movement, friction is the resistance that one surface or object encounters when moving over to another, and mass is a large body of matter with no definite shape.Velocity means the speed of something given direction which explains the question

Explanation:

centripetal force is a force that makes a body follow a curved path. for example, twirling,a lasso, cream seperator etc.

A force that causes an objectmoving in a circular path to move out and away from the centres of it's path is centrifugal force. for example,drifting, banked roads, washing machine etc.

Circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. for example, stirring batter, stone tied to a string etc

Answer:

0.4 g/cm^3

Explanation:

The density of an object can be found using the following formula.

d= m/v

where m is the mass and v is the volume.

The mass of the metal is 6 grams and the volume is 15 centimeters^3

m=6 g

v= 15 cm^3

Substitute these into the formula.

d= 6 g/ 15 cm^3

Divide 6 g by 15 cm^3 (6/15=0.4)

d= 0.4 g/ cm^3

The density of the metal is 0.4 grams per cubic centimeter.

Density = (mass) / (volume)

Density = (6 g) / (15 cm³)

Density = (6/15) (g/cm³)

Density = 0.4 g/cm³

This 'metal' has less than half the density of water, and it floats on water !  It cannot be of Earthly origin, and must have been dropped here by aliens.

Either that, or else the metal has been hammered and stretched and beaten out and shaped so that it has an artificially large volume ... something like the way sailing ships are made out of thick plates of steel.

Answer:

the height of the potential energy is 3,200 J

Explanation:

The computation of the kinetic energy is shown below:

Kinetic energy = 1 ÷ 2 × mass × velocity^2

= 1 ÷ 2 × 4 kg × 40 m/s^2

= 3,200 J

Hence the height of the potential energy is 3,200 J

At an atomic level, electrostatics is responsible for most of the physical phenomena that we encounter in our everyday life. Every object we see around us, such as chairs, buildings, and people, are made up of atoms, and every atom has electrons that are negatively charged, protons that are positively charged, and neutrons that have no charge.

Electrostatics is the study of electric charges at rest and of the forces and fields associated with these charges. Electrons are held in atoms by the attraction of the positive nucleus for the negative charge of the electrons. This attraction is known as electrostatic force. The protons in the nucleus are also held together by electrostatic forces, which are much stronger than those that bind electrons to the nucleus.
The forces between charged objects are governed by Coulomb's Law. This law states that the force between two charged objects is proportional to the product of their charges and inversely proportional to the square of the distance between them. If the charges have the same sign, the force is repulsive; if they have opposite signs, the force is attractive.
Electrostatic forces play an important role in many physical phenomena, such as the attraction of dust particles to a TV screen, and the Van de Graaff generator, which uses electrostatic forces to build up very high voltages.

Answer:

h = 35857 km

Explanation:

A geosynchronous orbit can be defined as circular orbit which lies on the Earth's equatorial plane and follows the direction of the Earth's rotation in a period that's equal to the Earth's rotational period and thereby appearing motionless, at a fixed position in the sky relative to the ground observers.

We are given;

Radius of earth(R) = 6.37 x 10^(6) m

Mass of earth (Me) = 5.97 x 10^(24) kg

Gravitational constant = 6.67 × 10^(-11) m³/kg.s²

The earth has a rotational period of 24 hours per day. This gives in seconds

T = 24 × 60 × 60

T = 86400 s

Let's make the height of the orbit from Earth's surface to be h

Also, let ω be the uniform angular velocity in rad/s with which the satellite rotates in the geosynchronous orbit

Now, equating the centripetal force with the gravitational force gives us;

mω²(R + h) = G•Me•m/(R + h)²

m will cancel out. Also ω can be written as 2π/T

Thus,we now have;

(R + h) = ∛(G•Me•T²/(4π²))

Plugging in the relevant values, we have;

(R + h) = ∛(6.67 × 10^(-11) × 5.97 x 10^(24) × 86400²/(4π²))

(R + h) = 42227 Km

Since R = 6.37 x 10^(6)m = 6370 km

Thus;. h = 42227 - 6370 = 35857 km

Answer:

The friction between the crate and the floor is the same amount as your pushing force when you push a crate across a level floor at constant velocity.

Explanation:

Remember that the force produced by two surfaces coming into contact and sliding against one another is frictional force. This is expressed by the direct relationship between frictional force and normal force.

f=μN

Where

f = frictional force

µ = coefficient of friction

N = Normal force

By dry friction, two solid surfaces in touch are opposed to one another's relative lateral motion. Dry friction is further separated into kinetic friction between moving surfaces and static friction (sometimes known as "stiction") between non-moving surfaces. Additionally, dry friction is typically caused by the interaction of surface characteristics, particularly rough surfaces.

Answer:

117.88m

Explanation:

We can use the formula [ s = ut + 1/2at^2 ] to solve this problem.

We know that constant acceleration is a = 9/8m/a^2, the initial velocity is 0,  and the height is 87 so the only variable we need to solve for is "t".

87 = 0t + 1/2(9.8)(t^2)

t = √174/9.8

t = 4.21s

Now multiply the time by the speed given.

28m/s * 4.21s = 117.88m

The system described by the transfer function G(s) = -co² s² + 2a + w², with a damping ratio of 1.3 and a natural frequency of 0.5, has an overdamped unit step response. So, the correct option is (E)

The transfer function of the system is given as G(s) = -co² s² + 2a + w², where co represents the damping ratio, a represents an arbitrary constant, and w represents the natural frequency of the system. We are given that the natural frequency is 0.5 and the damping ratio is 1.3.

To determine the type of unit step response, we need to analyze the damping ratio (co) in relation to the critical damping value (co_critical).

The critical damping ratio (co_critical) is defined as the value where the system is on the threshold between being overdamped and underdamped. It is given by the formula co_critical = 2 * sqrt(a * w²).

In our case, the natural frequency (w) is 0.5, so we can calculate co_critical as follows: co_critical = 2 * sqrt(a * 0.5²).

Since the damping ratio (co) is given as 1.3, we can compare it with co_critical to determine the type of unit step response.

If co > co_critical, the system is considered overdamped (Option E).

If co = co_critical, the system is considered critically damped (Option D).

If co < co_critical, the system is considered underdamped (Option C).

Based on the given values, we can determine that the system is overdamped (Option E) because the damping ratio (1.3) is greater than the critical damping ratio.

(The more gallons of milk you have is the thing that changes the whole outcome, which is the amount of milk that can be poured out)

Therefore, the inductance will increase by a factor of 4.

The inductance of a solenoid is given by the equation L = (μ0 * N^2 * A * l) / l, where N is the number of turns, A is the cross-sectional area, and l is the length of the solenoid.

If you double the number of turns and double the length of a solenoid, the inductance will increase by a factor of 4.

This can be seen by plugging in the new values into the formula:

L' = (μ0 * (2N)^2 * A * 2l) / 2l

By Using Euler's method with two steps, we can find the approximate value of Y(2) is 2.125. , where Y is the solution of the initial value problem dy/dx = x - y, and Y(1) = 3.

Euler's method is defined as a numerical technique which is  used to approximate solutions into ordinary differential equations. The method includes dividing the interval of interest into smaller steps and thereafter approximating the solution at each step by using the derivative of the function.

In this case, we are given the initial value problem dy/dx = x - y, with the initial condition Y(1) = 3. To approximate Y(2) using Euler's method with two steps, we will divide the interval [1, 2] into two equal steps.

Step 1:

We start with the initial condition Y(1) = 3. Using the differential equation dy/dx = x - y, we can approximate the value of Y at the midpoint of the interval [1, 2].

Using the step size h = (2 - 1) / 2 = 0.5, we can calculate Y(1.5) as follows:

Y(1.5) ≈ Y(1) + h × (x - y) = 3 + 0.5 × (1.5 - 3) = 3 + 0.5 × (-1.5) = 2.25

Step 2:

Now, using the value of Y(1.5) as the new approximation, we calculate Y(2) using the same process:

Y(2) ≈ Y(1.5) + h × (x - y) = 2.25 + 0.5 × (2 - 2.25) = 2.25 + 0.5 × (-0.25) = 2.125

Thus,  by using Euler's method with two steps, the approximate value of Y(2) is 2.125.

In this experiment, time represents the variable that is independent and graphed on the horizontal axis.

The period of the pendulum does not depend on the mass of the sphere, only on the length of the chord. Two pendulums with different masses but the same length have the same period. Two pendulums of different lengths have different periods with the pendulum with the longer string having a longer period.

For small deflections of less than 15 degrees, the pendulum experiences simple harmonic oscillations. This means that its restoring force is directly proportional to its deflection. A simple pendulum is called a simple pendulum. The longer the pendulum is, the longer it will take to travel the distance it swings from side to side. The period of a pendulum is the time it takes for the weight to swing and return to its original position so it means a longer period.

If the pressure has changed, it indicates that there has been a change in the number of molecules in the system. An increase in pressure suggests an increase in the number of molecules, while a decrease in pressure suggests a decrease in the number of molecules.

When the number of molecules in a system increases, there is a higher frequency of molecular collisions with the container walls. This increased collision rate leads to a greater force exerted on the walls per unit area, resulting in an increase in pressure.

Conversely, if the number of molecules in the system decreases, there are fewer collisions with the container walls, leading to a lower frequency of collisions and a decrease in pressure.

The specific heat of the china dish is 0.20 cal/g°C.

Mass of the serving bowl (m) = 248.0 g

Initial temperature of the china dish (t1) = ?

Final temperature of the china dish (t2) = 65.5°C

Difference in temperature (Δt) = 65.5°C - t1 = 65.5°C

Heat absorbed by the china dish (Q) = 1.5 kcal

The formula for specific heat is,Q = m × c × Δt

where, Q = Heat absorbed by the china dish

m = Mass of the serving bowl

Δt = Difference in temperature

c = Specific heat of the china dish

Now, let's substitute the values in the formula,1.5 kcal = 248.0 g × c × (65.5°C - t1)

We know,1 calorie = 4.18 joules

1 kcal = 1000 calories= 1000 × 4.18 joules= 4180 joules

Therefore,1.5 kcal = 4180 × 1.5 joules= 6270 joules

Thus, we can rewrite the above equation as:

6270 J = 248.0 g × c × (65.5°C - t1)

The units of c are J/g°C.

Therefore, the specific heat of the china dish is calculated by dividing both sides of the equation by the product of the mass and the difference in temperature.

c = 6270 J / (248.0 g × 65.5°C - t1)

c = 0.20 J / g°C (rounded to two decimal places)

Therefore, the specific heat of the china dish is 0.20 cal/g°C.
