Answer:
1. -Hydropower plants capture the energy of falling water to generate electricity
-a turbine converts the kinetic energy of falling water into mechanical energy.
- a generator converts the mechanical energy from the turbine into electrical energy.
2. In the case of a wind-electric turbine, the turbine blades are designed to capture the kinetic energy in wind. The rest is nearly identical to a hydroelectric setup: When the turbine blades capture wind energy and start moving, they spin a shaft that leads from the hub of the rotor to a generator.
Explanation:
hope this kinda helped.
Q=McDeltaT
Q=731g×1.00cal/g°c×(83°c-35°c)
Q=35088cal
therefore, their are 35088 calories are required to heat up 731g of water.
Glacier is apart of the cryospehere. cryospere is made up of ice
Sulphuric acid (H2SO2) is a dibasic acid. It generated H+ ions when dissolved in water. In order to neutralize an acid, a base containing hydroxy ion (OH-) will be required.
NaOH, Ca(OH)2, KOH, etc. can be used to neutralize H2SO4.
If NaOH is used as a base, following reaction is initiated.
2NaOH + H2SO4 → Na2SO4 + H2O
(base) (acid) (salt)
Density requires at least two things. In this case we would need volume of the object in addition to the mass. Density is equal to the mass divided by volume p = V/m
