What is a light how it will work |
|
Answer» They make LIGHT by passing electricity through a very thin WIRE filament so it gets incredibly hot. Excited atoms INSIDE the hot filament turn the electrical energy passing through them into light you can SEE by constantly giving off photons. When we make light by heating things, that's CALLED incandescencemark as brainlist |

Fill in the blank 1)____ in direction of the force 2) the rate of change in velocityis _____ 3) the rate of change of _______ is directly 4) F= Ma valid for _______ 5) Impluse is _____ |
|
Answer» Isaac Newton's First Law of MOTION states, "A body at rest will remain at rest, and a body in motion will remain in motion unless it is acted upon by an EXTERNAL force." What, then, happens to a body when an external force is applied to it? That situation is DESCRIBED by Newton's Second Law of Motion. According to NASA, this law states, "Force is equal to the change in momentum PER change in time. For a constant mass, force equals mass times acceleration." This is written in mathematical form as F = maF is force, m is mass and a is acceleration. The math behind this is quite simple. If you double the force, you double the acceleration, but if you double the mass, you cut the acceleration in half. |

a body moves from rest with a uniform acceleration of 470 cm in 6 seconds find its final velocity after 15 seconds |
|
Answer» tion:Given :INITIAL velocity (U) = 0 m/s.Distance (s) = 470 TIME (t) = 6 secs.To find:Acceleration (a) =?Velocity after 15. sec Solution :We will use third equation of motion here;s = ut + 1/2 at²→ 270. 0 * 6+1/2 * a * 6 * 6→ 470 =. 36/2 a→ 36 a = 940⇒a= 940/36 ⇒a= 26 m/ s Now,We will use first equation of motion here;After 15 secs.V = u+ at v. = 0+ 26 * 15 v= 390 v= 390 m/s Hence,The final velocity acquired by the car is 390 m/s hope it helps you |
