Ok I’m figuring this one out
The negative impact of the hydroelectric dam is local drought and massive flood by dam breakage.
The hydroelectric dam is the local water storage body that is used to convert the energy of the water to electrical energy. The plants are a huge source of electricity.
<h3>What is the dam's negative impact?</h3>
The dam is prepared in order to collect the local water in the bodies for the production of electricity. The collection of water required a larger force and pressure-bearing ability, thus dams are constructed with high-quality material.
The dams provide hydroelectricity, but the collection of water has been caused by the local drought conditions in the area. The dam breakage leads to massive floods as well.

Average speed (aka average velocity) is the change in displacement (distance) over the chance in time.
The average velocity of the baseball is 15 meters/sec
In a closed system, heat should be conserved which means that the heat produced in the calorimeter is equal to the heat released by the combustion reaction. We calculate as follows:
Heat of the combustion reaction = mC(T2-T1)
= 1 (1.50) (41-21)
= 30 kJ
14.285 % is the answer maybe but I am not sure
