Answer:
Nuclear energy has some advantages over traditional methods of producing electricity. It has little impact on air quality and is more efficient than traditional methods of producing electricity. It does, however, use a nonrenewable resource, uranium. Uranium must be mined just like coal, which does have detrimental effects on the environment. Nuclear power plants also produce radioactive waste, which leads to difficulties in storage. Also, nuclear power plants use large amounts of water and can contribute to thermal pollution.

Explanation:
Answer:
3.75m/s²
Explanation:
g= GM/r²
For planet 1
= GM/r² (i)
= 15m/s²
for planet 2
radius= 2*r= 2r
g= GM/r
= GM/(2r)²
= GM/4r²
= GM/r² *1/4
from (i)
= *1/4
= 15/4
= 3.75m/s²
Answer:
80 cm
Explanation:
the given condition is closed-end air column. The wavelength is four times the length of the air column for the standing wave pattern for the first harmonic.
The required wavelength of the standing wave pattern is
=
Answer:
Speed
Explanation:
If a vehicle hit any other object then its speed will slow down or some time the vehicle will stop its depends on the force exerted by other object on the vehicle.
The change in speed of vehicle is due to momentum because momentum is always conserved. So to conserve the momentum the speed of the vehicle decreases because after hitting the overall mass is increases.
Answer:
Vehicle
Explanation:
This is referring to mechanism that heat the object.
lithospheric theory
plate tectonics theory
nebular theory
Answer:
C. Plate tectonics theory
Explanation:
According to the plate tectonics theory outer layer of earth is divided into seven major and some minor plates. And these plates form convergent,divergent and transverse boundaries. So the Pacific ring of fire, subduction zone, continental drift are evidences of plate tectonics theory. Earthquakes and volcanic eruption are also explained by plate tectonics theory.
