४.खालील प्रश्नांची २५ ते ३० शब्दांत उत्तरे लिहा(१) लोकसभेचे सदस्य कसे निवडले जातात ?​

Answer»

रिक निवडणुकाद्वारे लोकसभेच्या सदस्यांची निवड केली जाते. लोकसभेच्या निवडणुका या दर पाच वर्षांनी होतात.लोकसभा निवडणुकीसाठी भौगोलिक मतदारसंघाची आखणी करण्यात येते.काहीवेळा पाच वर्षांची मुदत संपण्यापूर्वीच निवडणुका घेण्याची वेळ येऊ शकते.पाच वर्षांचा कालावधी पूर्ण होण्याआधी ज्या निवडणुका घ्याव्या लागतात त्यांना मध्यावधी निवडणुका म्हणून संबोधले जाते. अनेक वेळा अनेक कारणांनी मुदतीच्या आधी लोकसभा विसर्जित झाल्याची बरीच उदाहरणे आहेत. मात्र असे अपवादात्मकच आहे.

Explain the term "friction"​

Answer»

Friction is the resistance to motion of one OBJECT MOVING relative to another. It is not a fundamental force, like GRAVITY or electromagnetism. Instead, SCIENTISTS believe it is the result of the electromagnetic ATTRACTION between charged particles in two touching surfaces.

Explain inter locking of friction

Answer»

Friction is a result of interlocking. Every object has some IRREGULARITIES or roughness on its surface. when two different surfaces come in contact , their irregularities GO into each other and they INTERLOCK. THEREFORE, thefrictional force will be greater in case of rough surface than smooth surface.

A stone tied to the end of the string 80cm long is whirled in a horizontal circle with a constant speed. If the stone makes 14 revolutions in 25s . what is the magnitude and direction of acceleration of the stone.

Answer»

Length of string = 80CM= 0.8mStone makes 14 revolution in 25 sectherefore, Stone makes 14/25 revolution in 1 secfrequency= 14/25 sec^-1 We knowAngular SPEED (ω) = 2π×frequency=2π×14/25=28π/25 rad/secNow ACCELERATION(a) =ω²rwhere r is the radius { length of the string }Acceleration =0.8 × {28π/25}²= 9.91 m/s²Explanation:Hope this helps

The force acting vertically upward and has tendency of forcing the body to move up ​

Answer»

re two FORCES acting UPON the PERSON. The force of gravity exerts a downward force. The floor exerts an upward force. Since these two forces are of equal MAGNITUDE and in OPPOSITE directions, they balance each other.air resistance is an upward force exerted on falling objects. -Air resistance is not the same for all objects. ... The greatest velocity a falling object reaches is called its terminal velocity. Terminal velocity is reached when the force of air resistance equals the weight of the object.

•List the material required to verifyeffect ofroughness on frictionalforce​

Answer»

The relationship between normal force and friction force for a finger contacting a SURFACE was examined, and also the effect of surface roughness, using a finger friction rig. To investigate the normal force–friction force relationship 12 materials were used: 3 metals, 5 plastics and 4 elastomers. Forty tests were carried out across a range of loads, for each material. The roughness tests were run on three metals (brass, steel and aluminium), with a range of surface roughness. The deformation of the finger was also monitored in the normal force tests using a high-speed video camera.The finger tested, reached a maximum area of contact at a low load: 1 N. Therefore, for forces above 1 N, the main friction mechanism was adhesion. The plateau in contact area and dominance of adhesion resulted in a linear relationship between normal force and friction force, for all loads above 1 N.The roughness tests showed that at a low surface roughness the finger dominates the interaction, so little difference is seen between materials and roughness. However, as the roughness increases the friction increases LINEARLY, up to a point. At this point the friction does not vary as the WIDTH and height of the surface ridges are increased.

1. What happens when light travels fromdenser to rarer medium?​

Answer»

When light travels from a denser medium to a rarer medium, it bends away from the normal, as illustrated to the left. This BEHAVIOR follows from Snell's Law. As you saw before, the larger ANGLE MUST be in the medium having the LOWER index of refraction.
