Take its downward acceleration to be 10 ms-2 . - Physics Cbse class 11 1 AnswerSuppose your writing desk is tilted a little. A book kept on it starts sliding down. Show the direction of frictional force acting on it. cbse-class8-physics-20151 AnswerAn archer stretches her bow while taking aim at the target. She then releases the arrow, which begins to move towards the target. Based on this information fill up the gaps in the following statements using the following terms. cbse-class8-physics-20151 AnswerA bulb in a staircase has two switches, one switch being at the ground floor and the other one at the first floor. The bulb can be turned ON and also can be turned OFF by any one of the switches irrespective of the state of the other switch. 1 AnswerName the forces acting on a plastic bucket containing water held above ground level in your hand. Discuss why the forces acting on the bucket do not bring a change in its state of motion. cbse-class8-physics-20152 AnswerExplain why sliding friction is less than static friction. cbse-class8-physics-20151 AnswerWe had Constructed the RCC Building both Ground and First Floor of length 265 Feet without Expansion Joint What will happened?1 AnswerA room is 4 m long and 3 m 50 cm wide.
