The force F needed to keep the block at equilibrium in given figure is (pulley and string aremassless)(1)Mg/5(2)Mg/4(3)Mg/2(4)Mg/3 |
|
Answer» 1) Let the TENSION in the STRING be 'T' . Since, net force along the string is 0. => F-T=0 => F=T 2) Now, Tension is constant along the string . => Tension on both SIDES of pulley is 'T'. We need, to find the VALUE of 'F' to KEEP the system in equilibrium . => Net force on pulley must be 0. => 2T-Mg = 0 => T = mg/2. Hence, the value of F=T=Mg/2. |

An object of mass 500g is raised to a height of 25mm above the ground. What will be the potential energy stored in it? (g= 10m/s2) |
|
Answer» Answer is C.Potential energy is energy stored in an object. This energy has the potential to do work. Gravity gives potential energy to an object. This potential energy is a result of gravity pulling downwards. The gravitational constant, G, is the acceleration of an object due to gravity. This acceleration is about 10 METERS per second on earth. The FORMULA for potential energy due to gravity is PE = mgh. As the object GETS closer to the ground, its potential energy decreases while its kinetic energy increases. In this case, a body of mass 5 kg kept at a height of 10 m. So the potential energy is given as 5 * 10 *10 = 500 J.Hence, the potential energy of a body of mass 5 kg kept at a height of 10 m is 500 J.Explanation:have a great day |

Why do stars appear twinkling....???? |
|
Answer» As LIGHT from a STAR races through our atmosphere, it bounces and bumps through the different layers, bending the light before you see it. Since the hot and COLD layers of AIR keep moving, the bending of the light changes too, which causes the star's appearance to wobble or twinkle |

Please send me the Notes of class 9 ● physics ☆{motion }and ☆{force and the law of motion} |
|
Answer» In physics, motion is the phenomenon in which an object changes its POSITION over time. Motion is mathematically described in terms of DISPLACEMENT, distance, velocity, acceleration, speed, and time.Explanation:What are Newton's laws of motion? Newton's laws of motion relate an object's motion to the forces acting on it. In the FIRST LAW, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. |
