Identify the metal by their colour |
|
Answer» Most bronze is an alloy of copper and tin, but ARCHITECTURAL bronze actually has a small amount of lead in it. Bronze has a DARK coppery color and gets a GREEN oxide over a period of TIME. bronze's melting point is 850-1000°C (1562-1832°F) depending on how much of each metal is in it. Bronze is nonferrous. Because bronze is an alloy densities vary. Bronze vibrates like a bell when HIT. |

What is watt?????? |
|
Answer» The WATT is a unit of power or radiant flux. In the International System of Units, it is defined as a derived unit of 1 kg⋅m²⋅s⁻³ or, EQUIVALENTLY, 1 joule per second. It is used to QUANTIFY the rate of ENERGY transfer. The watt is named after James Watt, an 18th-century Scottish inventor. SI base units: kg⋅m2⋅s−3 |

give the experiment of current carrying rod ab experience of force perpendicular to its length and the magnetic field |
|
Answer» A current carrying conductor PLACED in a magnetic field experiences a force. If the direction of the field and that of current are mutually perpendicular to each other, then the force acting on the conductor will be perpendicular to both and that can be determined USING the FLEMING’s left-hand rule. When current establishes in the conductor, it gets DISPLACED which VERIFIES the existence of a force on the conductor. Explanation: |

Explain the measurement of masses |
| Answer» MASS is both a property of a physical body and a measure of its resistance to acceleration (rate of CHANGE of velocity with respect to time) when a net force is applied. An object's mass also DETERMINES the strength of its gravitational attraction to other bodies. The SI base UNIT of mass is the kilogram (kg).Explanation:hope it helps | |

Define ampere, potential difference, electric flux, specific resistance, junction and loop. |
|
Answer» One ampere can be defined as the unit of electric current and that is EQUAL to the flow of one coulomb of charges per second.Potential difference is the difference of electrical potential between TWO points.Electric flux, property of an electric field that may be thought of as the number of electric lines of force (or electric field lines) that INTERSECT a given area. Electric field lines are considered to originate on POSITIVE electric charges and to terminate on negative charges.Electrical resistivity is a fundamental property of a material that measures how STRONGLY it resists electric current. Its inverse, called electrical conductivity.Junction is a point where at least three circuit paths meet.A loop is any closed path going through circuit elements.HOPE ITS HELPFUL |

Decay rate for a certain mass of a radioactive substance measured at different times varies with time as shown in fig.countrate at `t=8` hr will be? |
| Answer» RADIOACTIVE decay is the loss of elementary particles from an UNSTABLE nucleus, ultimately changing the unstable element into another more stable element. There are five types of radioactive decay: alpha emission, beta emission, positron emission, electron capture, and GAMMA emission. Each type of decay emits a specific particle which CHANGES the type of product PRODUCED. The number of protons and neutrons found in the daughter nuclei (the nuclei produced from the decay) are determined by the type of decay or emission that the original element goes through. | |
