18m/s Explanation:initial VELOCITY =2M/'s , time = 2 's , g= -10 m/'s then using FORMULA v=u-at we GET v=18 m/s

It is a input power.Explanation:Because it transforms the power and acts as a input power.The there is energy loss the TOTAL energy is CONSERVED .Some par t is used to transforms the power and some part to HEAT the TRANSFORMER.

hope it helps .plz ASK if u have any DOUBT ND report if its not satisfactory

If you have ever awakened drenched in sweat, you might wonder: Why do we get sweaty in our sleep? If it occurs repeatedly, it MAY be ASSOCIATED with other medical conditions and may require further evaluation. It also may mean different THINGS in children and even in women going through menopause. Discover some of the reasons why we get sweaty in sleep.

lysis is that PROCESS in which substances or COMPOUNDS breaks into simpler charged entities or IONS when we PASSED ELECTRIC current through it.Thank you❤ ^_^

It's ANSWER is 1/3 HOPE HELP .....

tion:this is because sand particles are very loosely BOUND in COMPARISON to concrete particles. In fact concrete particles are attached to each other but sand particles are not. This decreases the reaction force being applied by the surface of sand and it CAUSES the particles to move away on stepping on it.However the concrete remains TOGETHER and this ALLOWS it to exert a force enough to support the weight of the person, and hence the person is able to walk on it.Also the concrete particles cannot move apart as they are bonded with each other.

tion:The main FUNCTION of the earth WIRE is to conduct the LEAKING current from the electrical appliance to the ground . It is conected to the outer metallic body of the appliance . It is necessary to earth metallic appliances , as it protects the user from electric shocks by TRANSFERRING the current to the earth.

tion:heavier OBJECTS fall faster than lighter objects only in the presence of air. Newton illustrated this in his "Feather and Coin" EXPERIMENT. only difference can be due to the surface area of the OBJECT, more surface area ENCOUNTERS more air resistance resulting in less SPEED.

tion:Radio waves do not FOLLOW a straight line because of BLOCKING objects in its PATH.

i m SORRY for my writing .if u CANT UNDERSTAND FOLLOW me i will TEXT u

tan alpha is ROOT 3 F2 -f1 = 10N EXPLANATION:SEE attached ans

work on both AC and DC. Unlike OLD INCANDESCENT LAMPS, CFLs and LED lamps will not operate on DC as they are FITTED with an inbuilt circuitry that rectifies AC to DC. But sufficiently HIGH DC voltage will lead to permanent failure of operation of the device.

nt carrying CONDUCTOR produces a magnetic field AROUND it which INTERACTS with the magnetic field in which it is held. Thus, it experiences a FORCE. Direction of this force depends upon the direction of current and the magnetic field.

zeroExplanation:an IDEAL FLUID is INCOMPRESSIBLE

t flows from the positive (+ve) terminal of the battery to the NEGATIVE (-ve). This is called conventional current flow. The problem is, electrons are NEGATIVELY charged, so they WANT to get away from the -ve and GO to the +ve. So if electrons are going left to right, you say that the current is going right to left (how confusing is that!)"

a region of marked thinning of the ozone layer in HIGH latitudes, chiefly in winter, attributed to the chemical action of CFCs and other atmospheric pollutants. The resulting INCREASE in ultraviolet LIGHT at GROUND level gives rise to an increased risk of SKIN cancer.

pulling a Band-Aid off, it is better to pull it fast. Your skin will REMAIN at rest due to inertia and the force pulls the Band-Aid off. 2)A car that is moving will continue even if you switch the engine off. 3)If a ball is on a slanted surface and you let go, gravity will make it ROLL down the slope. It has inertia and if there is a level area at the bottom of the slope, it will continue moving. 4)When entering a building through a rotating door, inertia will allow the door to hit you in the back if you don't get out of the way. 5)If you are rolling a cart with something on top and you hit something that MAKES the cart stop, what is on top may fall off. 6)It is harder to stop a big vehicle, like a bus, than a smaller vehicle, like a motorcycle. There is more inertia with the bigger object. 7)A concussion occurs because your brain is still moving while the outside skull is stopped. This is what causes the injury. 8)Space probes are launched to get past the Earth's atmosphere. Then they coast due to inertia. 9)If you are on a TRAIN and the train is moving at a constant speed, a toy tossed into the air will go straight up and then come down. This is because the toy has inertia like the train and you.10)One's body movement to the side when a car makes a sharp turn. 11)Tightening of seat BELTS in a car when it stops quickly. 12)A ball rolling down a hill will continue to roll unless friction or another force stops it.

ng with a CONSTANT speed: When the passenger in a train moving with a constant speed TOSSES a coin, the coin will fall back to the spot where it was tossed from as if the train was stationary. Because the coin is also moving with constant speed along with the train. 2. Accelerating: When the train is accelerating it changes its speed (increases),on the other hand the coin still moves with the same speed as before .So when the coin is tossed, by the time the coin reach back the train would have moved ahead and so the coin will fall behind the spot from where it was tossed. 3. Negatively accelerating: If the train was slowing down (or moving with negative acceleration) .On TOSSING, the coin would land ahead of the spot from where it was tossed. Because the coin moves with the same speed while the train slows down.

H=6.53m and R=45.24mExplanation:H=maximum HEIGHT And R=horizontal RANGE

if its KICKED at 30 with vertical MEANS angle with horizontal is 60.x COMPONENT of velocity never changes and is given 20.do 20=ucostheta20=ucos60therefore U = 40 .now u have u and theta just put the values and get the ans..max HEIGHT u^2 sin^2theta/2grange u^2 × 2sintheta cos theta/g

The ANGULAR displacement is defined as the ANGLE through which an object MOVES on a circular PATH. It is the angle, in radians, between the initial and final positions.

v' = v/2Explanation:By using the 3rd equation:2as=v^2 - u^2Since u=0So according to the question V= -/2aD ........ (1) Now LET v' be the VELOCITY when it COVER DISTANCE D/4So v'= -/2aD/4 = -/ aD/2 Now COMPARING it with the first equationv' = v/2Hope this helps

tion:as we know angular MOMENTUM =mvr( where r is the position vector) THUS when the sphere is rotating about its axis there is no effect on linear VELOCITY, REMEMBER angular velocity is not constant, and angular momentum will not change

d be POSSIBLE as the first PENDULUM WENT the SECOND ONE will also
