2 disadvantages would be damage to Marine life and hydroelectric plants are very expensive.If they plant is not stable and breaks it can cause flash floods and property damage.2 advantages would be that they do not emit any carbon emmissions.Some cities cannot build hydroelectric power plants because the stream does not have that kind of pressure .so really it matters greatly on where the dam would be placed. but sunny places like arizonasolar plant would be great
I hope this help
Answer:
Deceleration of 0.075m/s²
Explanation:
Given parameters:
Initial velocity = 5m/s
Time = 40s
Final velocity = 2m/s
Unknown:
The jogger's acceleration = ?
Solution:
To solve this problem, we use;
a = 
a is the acceleration
v is the final velocity
u is the initial velocity
t is the time taken
a = 
= - 0.075m/s²
D. thermometer. The warmer it gets, the more energy the particles gain and the more they move and 'expand', rising up the thermometer.
Answer: Heat
Explanation: Heat is a form of energy, and it is exchanged between bodys when they are not at the same temperature.
Heat is transferred from the body with higher temperature to the one with lower tempertature, this is so that in time they end up being at the same temperature.
This means that the one with lower temperature is the one who absorbs the heat, and the one with higher temperature transfer it.
