5. Meteors, or “SHOOTING stars,” are pieces of space rock that enter Earth’s atmosphere and burn up. As they burn, they look like streaks of light. During a meteor shower, many meteors enter the atmosphere at once. The Leonid meteor shower happens every November, when Earth passes through an area in space with many rocky bits.6. Asteroids are rocky objects primarily FOUND in the asteroid belt, a region of the SOLAR system that lies more than 2 ½ times as far from the Sun as Earth does, between the ORBITS of Mars and Jupiter. These objects are sometimes CALLED minor planets or planetoids.

-INITIAL Velocity of Train = u = 88.1 Km/h = 24.4 ms-¹Final velocity of train = v = 160 Km/h = 44.4 ms-¹Acceleration of Train = a = 0.25 ms-²Using First Equation of MOTION,v - u = at44.4 - 24.4 = 0.25tt = 20/0.25 t = 80 s Again,DISTANCE traveled,S = ut + 1/2 at²S = (24.4)(80) + 1/2(0.25)(80)(80)S = 1952 + 800S = 2752 mFinding distance traveled USING THIRD equation of Motion,v² - u² = 2aS(44.4)² - (24.4)² = 2(0.25)S1971.36 - 595.36 = 0.5SS = 1376/0.5S = 2752 m Hence,Distance travelled = S = 2752 m

The VALENCE ELECTRONS of an atom are responsible for and take part in chemical change. The valance electrons determinethe combining capacity or the valency OFTHE atom. The number of electrons in atom that actually take part in a chemical reaction is KNOWN as the valency of theelement.

I HOPE it HELPS in your ANSWER

s:Demerits of dobereiner's triads system: - This system fails because it does not hold good for all the elements DISCOVERED TILL date time. Merits:The only advantage of Dobereiner's research was that it made chemists look at elements in terms of GROUPS of elements with similar CHEMICAL and physical properties.

yes SPEED of SOUND DECREASE with INCREASING TEMPERATURE

When electric current is passed through a filament, it glows with bright light due to heating but doesn't happen in another wire. ... Filament has HIGH melting point (3400 degree C) and high resistance. As the filament POSSESSES high resistance, it converts electrical ENERGY into HEAT andlight energy.

b. U = v + gtExplanation:this equation is not for FREELY FALLING BODY and others equation are equation of freely falling body

istivity of a MATERIAL depends on its nature and the temperature of the conductor, but not on its shape and size. A good conductor has LESS resistivity. On the other HAND, a bad conductor or insulator has high resistivity. The LENGTH of wire - INCREASING the length increases the resistance.

Block and tackleA block and tackle or only tackle is a SYSTEM of TWO or more pulleys with a rope or cable threaded between them, usually used to LIFT heavy loads.The pulleys are assembled to form blocks and then blocks are paired so that one is fixed and one moves with the load.please follow me so that I can HELP you with other subjects also

tion:Answer: Voltmeter is the device connected in PARALLEL to a device in a CIRCUIT because it has high resistance.

Explanation:We know v = K GARB where K is a DIMENSIONLESS constant. [v] = [garb] [L T −1] = [(LT −2)a Lb] If we equate the POWERS on both sides we get  a+b = 1 -1 = -2a On solving we get a= ½ and b = ½ Therefore, v α (gr)1/2 So v2/rg is dimensionless.

lum is a body suspended from a fixed support so that it swings freely back and forth under the influence of gravity. When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a RESTORING force due to gravity that will accelerate it back toward the equilibrium position. When released, the restoring force acting on the pendulum's mass causes it to oscillate about the equilibrium position, swinging it back and forth. The mathematics of pendulums are in general quite complicated. Simplifying ASSUMPTIONS can be made, which in the case of a simple pendulum allow the equations of motion to be solved analytically for small-angle oscillations.Simple gravity pendulum EditAnimation of a pendulum showing the velocity and acceleration vectors.A simple gravity pendulum[1] is an idealized mathematical model of a real pendulum.[2][3][4] This is a weight (or bob) on the end of a massless cord suspended from a pivot, without friction. SINCE in this model there is no frictional energy loss, when given an initial displacement it will swing back and forth at a constant amplitude. The model is based on these assumptionsThe rod or cord on which the bob swings is massless, inextensible and always remains taut;The bob is a point mass;Motion occurs only in two dimensions, i.e. the bob does not trace an ELLIPSE but an arc.The motion does not lose energy to friction or air resistance.The gravitational FIELD is uniform.The support does not move.The differential equation which represents the motion of a simple pendulum is{\displaystyle {\frac {d^{2}\theta }{dt^{2}}}+{\frac {g}{\ell }}\sin \theta =0}{\displaystyle {\frac {d^{2}\theta }{dt^{2}}}+{\frac {g}{\ell }}\sin \theta =0} Eq. 1where g is acceleration due to gravity, l is the length of the pendulum, and θ is the angular displacement.

-Given:INITIAL Velocity (u) = 0 m/s ( the scooter starts from rest)Final Velocity (V) = 36 km/h1 km/h = 5/18 m/s→ v = 36 * 5/18→ v = 10 m/sTime TAKEN (t) = 10 sWe know that,acceleration (a) = (v - u) / t→ a = (10 - 0) / 10→ a = 10/10→ a = 1 m/s²Therefore, the acceleration of the scooter is 1 m/s².Additional Information:-Acceleration:Acceleration is the rate of change of Velocity with respect to time.a = Final velocity - initial Velocity/timeIt's S.I unit is m/s² and C.G.S unit is cm/s².It is a vector QUANTITY (has both DIRECTION and magnitude).It depends on two physical quantities Velocity, time.

Best current guess SUGGESTS that the GRAVITATIONAL and ELECTRICAL FORCES arise from symmetry breaking in a cosmological superforce sometime soon after the big bang. However, it may be that geometry (gravity) and the other forces are separate phenomenon.hope this is useful,please mark me as brainelist
