A ray of lights travels from water to glass, then the ray of light |
|
Answer» tion:What happens is that light slows down when it passes from the less dense air into the denser GLASS or water. This SLOWING down of the ray of light also CAUSES the ray of light to change direction. It is the change in the speed of the light that causes REFRACTION. |

If a wire of resistance 1 ohm is stretched to double it's lenght then the resistance will become please answer me the perfect answer |
|
Answer» 4ohmExplanation:The point here to understand is when we STRETCH a wire we increase is its length and as the volume of the wire is kept constant, so the area of the cross-section of the wire has to be now EXACTLY half of the initial value.Now let us say the original length of wire is '1',the area of cross-section of the wire is 'A' and the RESISTIVITY of the wire is 'P', then ACC. to the formula for resistanceR=P*(I/A)Now after stretching the wire,Length=2*l Area=A/2So the NEW resistanceR'=P*[21/(A/2)]R'=4*[P*(I/A)]R'=4RSo the new resistance is 4 times the initial resistance. |

The initial velocity of a free falling object is_ . |
|
Answer» Free-Falling Objects | Boundless Physics Equations. The best WAY to see the basic features of motion involving gravity is to start by considering straight up and down motion with no air resistance or FRICTION. This means that if the object is dropped, we KNOW the INITIAL velocity is ZERO. Once the object is in motion, the object is in free-fall. |

By using thin cotton tthread how will you find the length of a curved line |
|
Answer» Since the scale is a straight and it is very hard to bend it for getting the correct measurement of the curve line. Thus we need MUCH more flexible MEASURING thing to measure the curve line. So, a non-stretchable string or a THREAD is used to measure the length of curved line. Hence, both the ASSERTION and reason STATEMENT are correct and reason explains the assertion very well.

|
Answer» hlo mate here's your answer Explanation:FORCEForce cannot be seen, heard, or tasted. Only its effects can be felt or seen. The various effects of force are:1. It can move a body initially at rest.2. It can bring a moving body to rest.3. It can change the direction of a moving body.4. It can change the speed of a moving body.5. It can change the shape of a body.6. It can change the size of a body.Let us take an example of a football lying in a field (fig – A). When a player HITS the ball, it STARTS moving, i.e., it starts moving only when we apply force. Thus, force can move a body initially at rest.Now, if the goalkeeper catches the moving ball (fig – B), then it comes to rest. The goalkeeper applies a force to stop the moving ball. Hence, we can say that force can bring a moving body to rest.If ANOTHER player kicks the moving ball in the opposite direction (fig – C), then it starts moving in the directiontowards which it is kicked i.e. the direction of the football changes. The player applies force on the football to change its direction. Hence, force can change the direction of a moving body. ALSO, if the player hits the ball hard, then the NET speed of the ball will also change. Hence, the speed of a moving body can be changed by applying force.I HOPE IT HELPS YOU PLZ MARK AS BRAINLIST OK |

Calculate the velocity of a body of mass 2kg when it is at a height of 5m. falling freely from the height of 10m. |
|
Answer» Mass - 2 kgHeight = 15 mGravity - 10 m/s²Initial Momentum :Since the Ball is in rest, the initial velocity of the ball will be 0 m / s. Hence we know that,Initial Momentum = Mass * Initial Velocity ( U ) => Initial Momentum = 2 kg * 0 m / s = 0 kg . m / sFinal Velocity ( v ) = √ ( 2gh )Final Velocity = √ ( 2 * 10 * 15 )Final Velocity = √ 300 => 10√3 m / sHence Final Momentum = Mass * Final Velocity ( v )=> Final Momentum = 2 * 10 √ 3 => Final Momentum = 20 √ 3 kg . m / sHope my answer HELPED :-)EXPLANATION: please mark me briliant please f |
