One watt is equal to which of these values?

Physics

gregori [183]3 years ago
7 0

Answer:

Correct option: 1 joule/second

Explanation:

The Watt is the unit of measure of power of the International System of Units, it is represented by the letter W in uppercase, it owes its name to the Scottish James Watt.

The watt is a unit of power that equals 1 joule per second (1J / s). Or the work of moving a mass of 1 kilogram, a distance of 1 meter in a second of time. Hence the equivalence since force by distance is work and time divided by power. A horsepower equals 775 W. Expressed in units used in electricity, one watt is the electrical power produced by a potential difference of 1 volt and an electric current of 1 ampere (1 voltampere).

Explain the difference between rotation and revolution. Then use these terms to explain how earth
natima [27]

Answer:

The difference between rotations and revolutions is , when an object turns around an internal axis (like the Earth turns around its axis) it is called a rotation. When an object circles an external axis (like the Earth circles the sun) it is called a revolution.

Explanation:

While rotation means spinning around its own axis, revolution means to move around another object. Taking the example of the Earth, which rotates 366 times to complete one revolution around the Sun.

Black_prince [1.1K]

Answer:

None of the animals are from the same species

Explanation:

The exact question is as follows :

Given -

Felis catus

Sylvilagus audubonii

Parus inornatus

Euarctos americanus

Check out the list of scientific names. These names all represent animals. These are all animals but they cannot reproduce to produce fertile offspring with each other.

To find - What conclusion can be drawn from the past statement?

Solution -

The conclusion we can made from past statement is that - None of the animals are from the same species

Reason -

When two members of the same species reproduce, they produce fertile offspring.

According to the scientific names of the animals, there are different genus and species names.

The strength of the electric field at a certain distance from a point charge is represented by e. What is the strength of the el
Masteriza [31]

Answer:

At twice the distance, the strength of the field is e/4

Explanation:

F = the strength of an electric field.

F is inversely proportional to the squared distance from the point charge.

mathematically,

F = k(e/d²)

hence, if d is doubled,keeping other forms constant

F = e/4,

A piano tuner stretches a steel piano wire with a tension of 800 N. The steel wire is 0.400 m long and has a mass of 3.00 g. Wha
stepan [7]

Answer:

408.25 Hz.

Explanation:

The fundamental frequency of a stretched string is given as

f' = 1/2L√(T/m') .................... Equation 1

Note: The a steel piano wire is a string

Where f' = fundamental frequency of the wire, L = length of the wire, T = tension on the wire, m' = mass per unit length of the wire.

Given: L = 0.4 m, T = 800 N,

Also,

m' = m/L where m = mass of the steel wire = 3.00 g = 3/1000 = 0.003 kg.

L = 0.4 m

m' = 0.003/0.4 = 0.0075 kg/m.

Substituting into equation 1

f' = 1/(2×0.4)[√(800/0.0075)]

f' = 1/0.8[√(106666.67)]

f' = 326.599/0.8

f' = 408.25 Hz.

Hence the frequency of the fundamental mode of vibration = 408.25 Hz.
