Hydroelectric energy

Explanation:

In a dam area, the most likely energy resource would be an hydro-electric energy source.

Here the dammed water is used to produce electricity by forcing turbines to rotate.

  • Hydroelectric power stations are sited near huge water bodies especially a dam.
  • The moving water is used to drive heavy turbines that been designed to move electricity.
  • An area with huge amount of water has immense potential to generate hydroelectric power.

when uranium-238 decays, it emits 8alphas particles and 6 beta particles before finally becoming the stable daughter product. wh
sladkih [1.3K]

<u>Answer</u>:

When Uranium-238 decays, it emits 8 Alpha particles and 6 beta particles before finally becoming the stable daughter product. The atomic number and mass number of the daughter product ​is 92 and 234 respectively.

<u>Explanation</u>:

In the process of decay of Uranium-238, it emits alpha particles, and the resultant product is Thorium-234, which turns into Protactinium-234, and this Protactinium-234 undergoes the beta decay to form the Uranium-234.

As per the question, a stable daughter product is created after the emission of alpha and beta particles, this implies that Uranium-234 is a stable product after the decay of Uranium-238. Therefore, the atomic number is 92 (number of protons) and the mass number is 234 (protons+neutrons) which is also the element of the naming.

Why do tropical zones have a hot and humid climate year round and polar zones have a cold climate year round?
Ivenika [448]
Tropical places are hot because the humidity coming from the moisture of the plants and water are heated by the sun on the top layer of the tropical zone. The climate varies little in rain forest. There are five layers in the tropic trees so it's so thick that barely any light come through. This is also why vines grow up the trees so they can reach the sunlight to get nutrients. Also, the tropics are near the equator and that also causes the heat. The polars are cold because they barely get any sun heat to melt the snow or warm it up. The polars are melting due to certain chemicals and gasses in the atmosphere. also known as global warming. Hope that was helpful!

The way of transferring heat in that warm air rises in daytime is__.
Lunna [17]

Answer:

Option (3)

Explanation:

In a region where the temperature is high, the air gets heated up. As a result of which the air becomes warm and less dense and rises up into the atmosphere forming a low pressure zone. This air when rises up, it experiences a cooler temperature and gets cooled. This cooling allows the air mass to become dense and starts condensing. It then precipitates in the form of rainfall. This motion of air particles in the atmosphere forms a convection, that is similar to the one that forms in the mantle layer of the earth.

Thus, the warm air transfers heat forming convections.

Hence, the correct answer is option (3).
