What is power, work and energy?​

Answer»

wer is the rate at which work is done. Because work is energy transfer, power is also the rate at which energy is expended. A 60-W light bulb, for example, expends 60 J of energy per SECOND. Great power means a large amount of work or energy developed in a short time.WorkWork, in physics, measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is APPLIED in the direction of the displacement. EnergyEnergy, in physics, the capacity for doing work. It may exist in potential, kinetic, THERMAL, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another. hope it helps...have a good day...mark as brainliest...follow me...

Show that the motion of one projectile as seen from another projectile will always be a straight line motion. ........... with full explanation..........​

Answer»

Ua and Ub are the initial velocities of two projectiles and ‘’x’’ and ‘’y’’ are consider as direction. So components of relative velocities in both directions will be, Therefore relative velocities between these two projectiles will be, In this case RESULTANT VELOCITY will be constant and it will make an ANGLE with HORIZONTAL axis. Therefore motion of one projectile when viewed from other projectile will be a straight line motion.

A light body is projected with a velocity 00i+20j+20 k) ms. Wind blows alongX-axis with an acceleration of 2.5 ms. IfY-axis is vertical then the speed of particleafter 2 second will be (g 10 m )(A) 25 ms (B) 10/5 ms(0) 30 m(D) None of these​

Answer»

Option (D) None of theseExplanation:GivenVelocity of the body = Acceleration of the wind in the X direction = 2.5 m/s^2Since the wind will be blowing opposite to the motionTherefore, it will be negativeor, After 2 seconds the component of the velocity in the x direction will bev = u + at   (USING FIRST EQUATION of motion)v = 0 - 2.5 × 2or v = -5 m/sAlso the acceleration DUE to gravity will be acting in the y-directionTherefore, velocity in y-direction after 2 secondsv'= u'-gt v'= 20 - 10 × 2or, v' = 0Therefore the velocity vector after 2 seconds will beSpeed of the particle m/s

I Ohm's law in detail ​

Answer»

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage ACROSS the two points. Introducing the constant of proportionality, the resistance, one arrives at the usual mathematical EQUATION that describes this relationship:    I = V/R where I is the current through the conductor in units of amperes, V is the voltage measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms. More specifically, Ohm's law states that the R in this relation is constant, INDEPENDENT of the current. Ohm's law is an empirical relation which accurately describes the conductivity of the vast majority of electrically conductive materials over many orders of magnitude of current. However some materials do not obey Ohm's law, these are called non-ohmic.The law was named after the German physicist Georg Ohm, who, in a treatise published in 1827, described measurements of applied voltage and current through simple electrical circuits containing various lengths of wire. Ohm explained his experimental results by a slightly more complex equation than the MODERN form above.In physics, the term Ohm's law is also used to refer to various generalizations of the law; for example the vector form of the law used in electromagnetics and material science:    J = σ E , where J is the current density at a given location in a resistive material, E is the electric FIELD at that location, and σ (sigma) is a material-dependent parameter called the conductivity. This reformulation of Ohm's law is due to Gustav Kirchhoff.

Why can't we see clearly though fog? Name the phenomenon responsible for it.

Answer»

Because the light is not going straight from any OBJECT into your eye. Even WORSE: the path that each photon of light TAKES through fog is different. That is why we can not form an image through fog even though much of the light passes through.The process that changes the direction of the light in fog is called “scattering”. The minuscule droplets of water in fog are scattering the light. The direction of the scattering is determined by the path of the light through the droplet. They are very SMALL, and if they move only a little bit, the light is SCATTERED in a radically different direction. And since the drops are moving around all the time there is no consistent pattern.

17. A bicycle moves with a constant velocity of 5 km/h for 10 minutes and then decelerates at the rate1 km/h”, till it stops. Find the total distance coveredby the bicycle.​

Answer»

Total distance covered by the car = 13.3 kmStep by step explanations :Given that, A bicycle moves with a constant velocity of 5 km/hfor 10 minuteshere, Initial velocity of the bicycle = 5 km/htime taken = 10 miniutes = 10/60 h= 1/6 HWE know that in a constant velocity acceleration is 0so, S = ut + ½ at²S = 5(1/6)S = 5/6 km now BRAKES are applied so final velocity = 0 m/sgiven acceleration = -1 km/h²now we have, Initial velocity(u) = 5 km/hfinal velocity(v) = 0 km/hacceleration(a) = -1 km/hv² = u² + 2as(0)² = 5² + 2(-1)s-2s = -25S = 25/2now total distance covered by the bicycle = 5/6 + 25/2(10 + 150)/12= 160/12= 13.3 km so, Total distance covered by the car = 13.3 km
