Answer:

Grounded ( neutral)

Explanation:

In electrical works there are usually safety measures which needs to be specially adhered to.

We have to take into perspective the dangers associated with the open neutral (grounded conductor) which is the main treason why NEC 300.13(B) does not permit the continuity of the grounded(neutral) conductor to depend on a receptacle.

Answer:

3.mechanical is the answer

Mechanical energy is missing in the windmill energy transformation.

Wind> Mechanical> Electrical. Hence option (3) is correct.

The process of using the wind to produce mechanical or electrical energy is known as wind power or wind energy. The kinetic energy of the wind is transformed into mechanical power by wind turbines. This mechanical energy can be used to particular activities (such pumping water or grinding grain) or can be transformed into electricity by a generator.

When the project size is created to match the energy requirements of the load while simultaneously monetizing economies of scale and equipment track record, wind turbine economics are maximized. A modest turbine (usually less than 10 kW) that can produce the amount of electricity needed by a residence for daily operation is needed for residential onsite energy consumption.

Answer:

Sorensen invented the insulated sleeve to fit around a standard paper coffee cup saving millions of coffee drinkers from burns. The sleeve was called the Java Jacket for which he obtained patent protection. Java Jacket, Inc. was incorporated in 1993 by Inventor Sorensen with an investment of just $20,000.Oct 8, 2013

Answer:

Housed in the same building as Vincent van Gogh’s “The Starry Night” and Andy Warhol’s “Campbell’s Soup Cans” is a simple paper coffee cup sleeve. It can be found not in the café at New York’s Museum of Modern Art (MoMA), but rather in the museum’s collections alongside renowned works of art worth millions. But it would be wrong to consider it out of place; the genius of the coffee cup sleeves makes it a million-dollar object as well.

For many, the morning ritual wouldn’t be complete without standing in line at a nearby coffee shop, placing an order with a frazzled cashier managing the A.M. rush and watching the barista pour the coffee, slap a slid on top of the cup and slip a cardboard sleeve over it. It’s a simple and logical ritual, but without that sleeve, what would have happened to our to-go coffee culture? In 2005, MoMA paid tribute to this ingenious design defining the modern American coffee tradition when it acquired a standard coffee cup sleeve for the exhibit “SAFE: Design Takes on Risk,” which featured products that were created to protect. The sleeve takes pride of place at MoMA, alongside Post-It notes, Bic pens and Band-Aids in a collection called “Humble Masterpieces.”

Explanation:

Heat is defined as a form of energy due to temperature difference. Heat is also a measure of the total internal energy of a body.

Heat  has the following effects;

1) Heat causes change of state of a body

2)  Heat changes the temperature of a body

3) Heat causes expansion of a body

4) Heat may alter certain physical properties of a body such as electrical conductivity, density etc

5) Heat causes a change in the pressure and volume of a body

6) Heat may lead to the emission of electrons from metals(thermionic emission)

Answer:

  R = 0.14  Ω

Explanation:

The resistance of a metal is given by the relation

         R = [tex]\rho \frac{L}{A}[/tex]

where ρ the resistivity is 5.6 10-8 Ω m, they also give the length and the cross section (area)

Let's reduce the magnitudes to the SI system

        L = 200cm (1m / 100cm) = 2.00m

        A = 8.0 10⁻⁷ m²

let's calculate

       R = 5.6 10⁻⁸  [tex]\frac{2.00}{8.0 \ 10^{-7} }[/tex]

       R = 1.4 10⁻¹ Ω

       R = 0.14  Ω

Answer: 288 m

Explanation: 288 m is the correct answer because the question states that the ball is thrown at 96 m every second, and our question tells us that the ball travels 3 seconds. This means we have to multiply 96 x 3 = 288 m.

Answer:

7.5s

Explanation:

Given parameters:

Velocity  = 30m/s

Deceleration  = 4m/s²

Unknown:

Time it takes for the car to come to complete rest  = ?

Solution:

 To solve this problem, we use the kinematics expression below:

        v  = u + at

 Since this is a deceleration

         v  = u - at

v is the final velocity

u is the initial velocity

a is the acceleration

t is the time taken

         v - u  = -at

         0  - 30  = -4 x t

              -30  = -4t

               t  = 7.5s

Answer:

Glass is denser than air, so a light ray passing from air into glass slows down. If the ray meets the boundary at an angle to the normal , it bends towards the normal. The reverse is also true. A light ray speeds up as it passes from glass into air, and bends away from the normal by the same angle.

Explanation:

Answer:

a = 7.5 [m/s²]

Explanation:

To solve this type of problem we must remember Newton's second law, which tells us that the sum of forces on a body is equal to the product of mass by acceleration.

∑F = m*a

where:

∑F = sum of forces [N]

m = mass = 0.1 [kg]

a = acceleration [m/s²]

Now replacing:

[tex]0.9-0.15=0.1*a\\a=7.5 [m/s^{2} ][/tex]

[tex]ke = \frac{1}{2} m{v}^{2} \\ = \frac{1}{2} (600)( {40}^{2} ) \\ = 300 \times 800 = 240000 = 240kjoule[/tex]

Answer:

Workdone = 3000Nm

Explanation:

Given the following data;

Force, F = 1000 N

Distance, d = 30 m

We know that workdone is given by the formula;

Workdone = force * distance

Substituting into the equation, we have;

Workdone = 1000 * 30

Workdone = 3000Nm
