The amount of potential energy possessed by an elevated object is equal to
Sedbober [7]

Answer:

Potential energy of the object will be equal to mgh

Explanation:

Let the mass of the object is m

Acceleration due to gravity is gm/sec^2

Let the object is released from height h

We have to find the potential energy

Potential energy is of an object released from height h is equal to

U=mgh, here m is mass, g is acceleration due to gravity and h is height from which object is released.

A hiker determines the length of a lake by listening for the echo of her shout reflected by a cliff at the far end of the lake.
ArbitrLikvidat [17]

Answer:

L = 499 m

Explanation:

  • If we assume that the speed of sound is constant, that travels along a straight line, and that the echo is instantaneous, we can find the total distance travelled by the sound, as follows, just applying the definition of average velocity:

       \Delta x = v_{s} * t = 343 m/s* 2.91 s = 998 m

  • If we assume that the time needed to reach to the cliff, is the same used for the return travel, the length of the lake will be exactly half of the total distance calculated:

        l_{lake} = \frac{\Delta x}{2} = \frac{998m}{2} = 499 m

  • The length of the lake is 499 m.
