Answer:

use own words!!!

Explanation: Velocity increases as more water is added to rivers via tributary rivers. This means that less of the water is in contact with the bed of the river and the mouth so there is less energy used to overcome friction. Hence rivers flow progressively faster on their journey downstream.

How much gravitational potential energy does a 7.3 kg rock have if it is sitting on the edge of a cliff that is 12 m high?

nordsb [41]

Answer:

The given data provided in the question is as follows:

Mass (m) = 7.3 kg

Height (h) = 12 m

Gravitational acceleration (g) = 9.8m/s²

We have given to find out the gravitational potential energy produced i.e

Gravitational potential energy (GPE) = ?

The standard formula for calculating GPE is given by,

$\mapsto\tt{m \times g \times h}$

$\mapsto\tt{7.3 \times 9.8 \times 12}$

$\mapsto\tt{71.54 \times 12}$

$\mapsto\tt{858.48}$

Thus, the value of gravitational potential energy is 858.48 J
