A 12.58 kg block is slid from a height of 9.16 m down a friction-less incline. It comes to a flat surface and crosses a 5.89 m strip of sandpaper with a coefficient of friction of 0.32. After passing over the sandpaper, the block is traveling on a friction-
less surface again. How fast is the block traveling?

sonar - device which is used to find the submit submarines, sankalp ship. sonar waves consists of a transmitter and detector which are installed in the observation centre on board of a ship. the ultrasonic waves are sent into the sea at high frequency about 1000 khz in all direction.

explanation:

wind is defined by the direction it blows from.   for example, a wind blowing from north to south is called a northerly wind.

connect the batteries in series and hope

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
