To create friction, we need ________surfaces. |
|
Answer» Increasing the area of surfaces that are touching also increases the FRICTION between them. That's why you can't SLIDE as far across ice with SHOES as you can on the thin blades of skates. The greater SURFACE area of the soles of the shoes cause more friction and slow you down. Heavier objects also have more friction. I hope it will help you army keep smiling have a NICE day |

2. Find out the magnitude of force actingon a box when 1000 J of work is done todisplace it by 5 m. |
Answer» GIVEN :-Work done by the force = 1000 J The DISPLACEMENT of the box = 5 m To Find :-The magnitude of force acting on a box. Analysis :-Here we are given with the work done and the displacement of the body. In order to find the force applied substitute the given VALUES such that, work done is equal to the force applied MULTIPLIED by the displacement. Solution :-We know that,
Using the formula, Given that, Work done (w) = 1000 J Displacement (s) = 5 m Substituting their values, ⇒ w = f × s ⇒ 1000 = f × 5 ⇒ f = w/s ⇒ f = 1000/5 ⇒ f = 200 N Therefore, the magnitude of force acting on a box is 200 N. |

The length of a straight line is measured a number of times by a number of observers. The following are the resultsof these measurements. Decide precision and accuracy. Actual length = 3.785 cm ± 0.001 cm Ist set of measurements 3.8 Cm, 3.9 cm, 3.7 cm2nd set of measurements 3.478 cm, 3.479 cm, 3.478 cm, 3.478 cm, 3.479 cm3rd set of measurements 3.55 cm, 3.65cm, 3.45 cm, 3.35 cm4th set of measurements 3.784 cm, 3.785 cm, 3.784 cm, 3.785 cm, 3.784 cm |
Answer» Answer :Frist set of MEASUREMENTS are accurate because it is close to the actual VALUE and it is not precise. Second set of measurements are not accurate and it is most precise because the readings are reproducible. Third set of measurements are NEITHER accurate nor precise. Fourth set of measurements are accurate as well as precise The accuracy of a measurement is a measure of how close the measured value is to the true value of the QUANTITY. Precision tells us to what resolution or limit the quantity is measured. |

Why does light ray gets refracted? |
|
Answer» Answer: Light refracts whenever it travels at an ANGLE into a substance with a DIFFERENT refractive index (optical density). This change of direction is caused by a change in speed. For example, when light travels from AIR into WATER, it slows down, causing it to continue to travel at a different angle or direction. |

Draw the graphical representation of virginal wave high frequency and low frequency waves |
|
Answer» Explanation: The STRING along which the waves traveled in the examples in CHAPTER 23 may be referred to as the medium along which the waves were propagated. It is a one-dimensional medium, but waves are frequently propagated through two- and three-dimensional MEDIA. If we strike a block of wood, we suddenly displace and compress the wood in the immediate vicinity of the point of impact. Two sorts of waves thereupon spread out in all directions from that point: transverse waves for which the particle motion is at RIGHT angles to the direction of travel or propagation of the wave, and longitudinal waves, involving particle motions along the direction of propagation, and so involving density variations. |

When you spread iron fillings near a bar magnet, they do not get attracted equally towards different parts of the magnet. Can you explain this unequal distribution of iron fillings around the magnet? |
|
Answer» Answer: this is because the magnet field of magnets are STRONGEST at the poles. That is why most of the iron FILLINGS will GET ATTRACTED to the ends of the magnets and only a LITTLE will get attracted to the center of the magnet. |
