Explanation: → At FIRST FIND the height above the ground at which STONE is STOPPED.H1 max = ut + 1/2gt²H1 = 0 + 1/2×9.8× 5×5H1= 122.5mNow ,It is given in question that srone stopped after 3sec(Vertical direction travelled in 3sec)=H2= 0+1/2×9.8×3×3H2= 44.1mRemaning distance= (122.5-44.1)=78.4mNow,78.4 = ut+1/2×9.8×t²78.4=0+4.9t²t= 4secTotal time taken =[4+3]=7sec✓✓Happy to HELP!:)

car turns, ACCELERATION is produced.So, initial velocity due north (U)=10 m/sFinal velocity EAST (V)=10 m/sTime interval (t)=10 sFollowing vectors:- √10²+10²=√200=10√2 m/s=change in velocitySo, acceleration (a)=v-u/t=10√2/10=√2 m/sSo, average acceleration is equal to √2 m/s

lify LET SAYA =  Xi   => Magnitude of Vector A = XThen resultant Vector C =  4j  mPerpendicular to one of vector with magnitude 4mVector B = Vector C  - Vector A=> B =  4j - XiMagnitude of B = √(4² + X²)sum of the magnitude of TWO VECTORS is 8m=> X + √(4² + X²) = 8=> √(16 + X²)  = 8 - XSquaring both sides16 + X² = 64 + X² - 16X=> 16X = 48=> X = 3Vector A = 3i   => Magnitude = 3Vector B = -3i + 4j  => Magnitude = √(-3)² + 4² = 5Vector C = 4jMagnitude of two vector = 3 & 5Please mark as brainliest answer

ection of a good source of energy depends on the following FACTORS:It should be POLLUTION free.It should be economical.3.It should be EASILY accessible.It should not be difficult to transport energy from there.It should not PRODUCE RADIOACTIVE waste.It should have a high calorific value.

tion:if a body COVERED equal DISTANCE in equal interval of time in a specified DIRECTION it BUDDY shape to moving with uniform velocity

Nm2/C is the SI UNIT for ELECTRIC FLUX !

cceleration is constant, so we use the equation for constant accelerationVf = Vi + aT   ⁻⁻⁻⁻⁻⁻⁻⁻⁻  (1)Where Vi is the initial velocity            Vf the final velocity            a is acceleration            T is time takenGiven values are Vi = 3I - 8jVf = 2I + 4jT = 4 SECA = ?Putting these values in equation (1), we get(2i + 4j) = (3i - 8j) + a (4)4 a = (2i + 4j) - (3i - 8j)4 a = (2i - 3i) + (4j + 8j)4 a = -i + 12ja = -1/4 i + 3 j This is the REQUIRED acceleration.Hope it helps.

tion:Sound is produced when SOMETHING vibrates. The vibrating body causes the medium (water, air, etc.) around it to vibrate. Vibrations in air are called traveling longitudinal WAVES, which we can HEAR. Sound waves consist of AREAS of high and low pressure called COMPRESSIONS and rarefactions, respectively.

magnetic PROPULSION (EMP), is the principle of accelerating an object by the utilization of a flowing electrical current and magnetic FIELDS. The electrical current is USED to either create an OPPOSING magnetic field, or to charge a field, which can then be repelled.

owing of bulb is a physical change.When an electric CURRENT is PASSED through the filament of a bulb, the filament starts glowing and the glow stops as soon as the current is cut off. The chemical composition of the tungsten filament does not change on application of current.Burning of candle is both a physical change as well as a chemical change. Candle is MADE up of a solid block of wax with a wick embedded in it.1) Physical ChangeWhen candle is lit, the heat of the flame melts the solid wax to liquid wax. This signifies a physical change from solid state to liquid state.2) Chemical ChangeThe wax acts as a fuel when we light the candle and is basically a chemical substance called carbon. The carbon combines with oxygen to form ANOTHER chemical substance called carbon dioxide. Also the unburnt carbon is deposited as BLACK substance called soot. This signifies a chemical change.

Hey MATE COMPLETE your question FIRST properly.....where are the options....???hope u understand.....

this is because of ACTION REACTION LAW

size of the atom were ENLARGED to the tip of the sharp PIN, how large WOULD the height of the Mount EVEREST be ---- ${{10}^{10}}$m

e bullet strikes, its HIGH velocity and small frontal cross-section means that it will exert large stresses in any object it hits. This usually results in it penetrating any soft object, such as flesh. The ENERGY is then DISSIPATED in the wound track FORMED by the passage of the bullet. See terminal ballistics for a fuller discussion of these effects.due to the transfer of energy the target BECOMES hotIf this helps so pls mark my answer as brainliest and thank it ........

and R2 be the two resistances. When they are in PARALLEL, resultant RESISTANCE Rp is given by1/Rp = 1/R1 + 1/R2Rp = R1R2/(R1 + R2)2 = R1R2/(R1 + R2)2(R1 + R2) = R1R2When they are in series effective resistance Rs = R1 + R29 = R1 + R2 ⇒ R2 = 9 - R12 x 9 = R1 R2          = R1 (9 - R1)          = 9R1 - R12.18 = 9R1 - R12.R12 - 9R1 + 18 = 0Solve this quadratic equation. You will get R1 = (9 ± √(81 - 4 x 1 x 18))/2      = (9 ± √9)/2      =  (9 ± 3)/2R1 = 3 ohm or 6 ohmIf R1 = 3 ohm, R2 = 6 ohm and vice versa.
