Explanation:Given :Height (h) = 10 mFinal velocity (v) = 0 m/sAcceleration due to gravity (g) = -9.8 m/s²To FIND :It's velocity & Time taken to reach MAXIMUM height. Solution :We KNOW,Height = Distance => 10 m = Distance => Distance = 10 mApplying 3rd equation of motion,v² = u² + 2gs=> 0² = u² + 2 × -9.8 × 10=> -u² = -196=> u² = 196=> u = 14 m/sApplying 1ST equation of motion,v = u + at=> 0 = 14 + -9.8 × t=> -14 = -9.8t=> 14 = 9.8t=> t = 14/9.8=> t = 1.43 sHence :It's velocity & Time taken to reach maximum height is 1.43 s.

Hooke's law states that WITHIN the elastic LIMIT, stress is directly PROPORTIONAL to STRAIN. THUS, Stress = A strainStress = M strain. ∴M=stressstrain. The constant of proportionality (m) is called the modulus of elasticity.

rent Transformer ( C.T. ), is a type of “INSTRUMENT transformer” that is designed to produce an alternating current in its secondary winding which is proportional to the current being MEASURED in its primary. Current transformers reduce high voltage currents to a much lower value and provide a convenient way of safely monitoring the actual electrical current flowing in an AC transmission line using a STANDARD ammeter. The principal of operation of a basic current transformer is slightly different from that of an ordinary voltage transformer.typical current transformerTypical Current TransformerUnlike the voltage or power transformer looked at previously, the current transformer consists of only one or very few turns as its primary winding. This primary winding can be of either a single flat turn, a coil of heavy duty wire wrapped around the core or just a conductor or bus bar placed through a central hole as shown.Due to this type of arrangement, the current transformer is often referred too as a “SERIES transformer” as the primary winding, which never has more than a very few turns, is in series with the current carrying conductor supplying a load.The secondary winding however, may have a large number of coil turns wound on a laminated core of low-loss magnetic material. This core has a large cross-sectional area so that the magnetic flux density created is low using much smaller cross-sectional area wire, depending upon how much the current must be stepped down as it tries to output a constant current, independent of the connected load.The secondary winding will supply a current into either a short circuit, in the form of an ammeter, or into a resistive load until the voltage induced in the secondary is big enough to saturate the core or cause failure from excessive voltage breakdown.Unlike a voltage transformer, the primary current of a current transformer is not dependent of the secondary load current but instead is controlled by an external load. The secondary current is usually rated at a standard 1 Ampere or 5 Amperes for larger primary current ratings.There are THREE basic types of current

In physics, a gravitational field is a MODEL used to EXPLAIN the influences that a massive body extends into the space around itself, producing a force on another massive body. THUS, a gravitational field is used to explain gravitational phenomena, and is MEASURED in newtons per kilogram

tion:Magnetic Field Due To Current Carrying ConductorCurrent is generally defined as the rate of flow of charge. We already know that STATIONARY CHARGES produce an electric field which is proportional to the magnitude of the charge. The same PRINCIPLE can be applied here, MOVING charges produce magnetic fields which are proportional to the current and hence a current carrying conductor produces magnetic effect around it. This magnetic field is generally attributed to the sub-atomic particles in the conductor, for e.g. the moving electrons in the atomic orbitals.A magnetic field has both magnitude and direction. Hence, it is a vector quantity and is denoted by B (in the diagram given below). Magnetic field due to a current-carrying conductor depends on the current in the conductor and distance of the point from the conductor. The direction of the magnetic field is perpendicular to the wire. If you wrap your right hand’s fingers around the wire with your thumb pointing in the direction of the current, then the direction in which the fingers would curl will give the direction of the magnetic field.Hope it helps...PLS mark me as Brainliest And give thanks

There are actually three, Kepler’s laws that is, of planetary motion: 1) every PLANET’s orbit is an ellipse with the Sun at a focus; 2) a line joining the Sun and a planet SWEEPS out equal AREAS in equal TIMES; and 3) the square of a planet’s orbital PERIOD is proportional to the cube of the semi-major axis of its orbit. As it’s the third which is most often used, Kepler’s law usually means Kepler’s third law (of planetary motion).

tion:A common TYPE of short circuit occurs when the POSITIVE and NEGATIVE terminals of a BATTERY are connected with a low-resistance conductor, like a wire. With a low resistance in the connection, a high CURRENT will flow, causing the delivery of a large amount of energy in a short period of time.

al energy is the energy POSSESSED by the body by virtue of its POSITION or configuration.Consider a body of mass m at a height 'h' from the ground.The amount of WORK DONE to raise this body to this height h against the force of GRAVITY:W=F×h where F is the force of gravity .W=mgh

b=0Explanation:Vector  a  is PERPENDICULAR to vector  b  if their dot product,  a⋅b  is  0 .This is because  a⋅b  is defined as  |a||b|cos(θ)  where  θ  is the angle between  a  and  b .That is, it is the product of their magnitudes and the cosine of the angle between them. Of course, if the angle is  90∘ , then  cos(90∘)=0  and so  a⋅b  will  be 0 PLZ mark me as a BRAINLIST. Have a NICE day.Hope my answer helped

Explanation:In this method, speed variation is accomplished by MEANS of a variable resistance INSERTED in series with the shunt field. An increase in controlling resistances reduces the field CURRENT with a REDUCTION in flux and an increase in speed. This method of speed control is INDEPENDENT of load on the motor.

Mass is a measure of the amount of matter in an object. ... Mass is USUALLY measured in GRAMS (g) or KILOGRAMS (kg). Velocity is defined as the rate change of DISPLACEMENT per unit TIME. Speed in a specific direction is also known as velocity. Velocity is equal to displacement divided by time.

EnergyIn physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a GIVEN mass from rest to its STATED velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its SPEED changes.Potential EnergyPotential energy, stored energy that DEPENDS upon the relative position of various parts of a system. A spring has more potential energy when it is compressed or stretched. A steel ball has more potential energy raised above the ground than it has after falling to Earth.

Temperature difference in any situation results from energy flow into a system or energy flow from a system to surroundings. The former leads to heating, whereas latter leads to cooling of an object.NEWTON’s Law of Cooling states that the RATE of temperature of the body is proportional to the difference between the temperature of the body and that of the surrounding medium. This statement leads to the classic equation of exponential decline over time which can be applied to many phenomena in science and engineering, INCLUDING the discharge of a capacitor and the decay in radioactivity.Newton's Law of Cooling is useful for studying water heating because it can TELL us how fast the hot water in PIPES cools off. A practical application is that it can tell us how fast a water heater cools down if you turn off the breaker when you go on vacation.Suppose that a body with initial temperature T1°C, is allowed to cool in air which is maintained at a constant temperature T2°C.Let the temperature of the body be T°C at time t.Then by Newton’s Law of Cooling,

What do you MEAN by that QUESTION I can't UNDERSTAND

In a fibre, the refractive index of core and cladding depends on wavelength. Each PROPAGATING wavelength "sees" a different refractive index. Therefore those different wavelengths in each pulse will TRAVEL at slightly different speeds, which CAUSES distortion LEADING to pulse broadening in TIME.
