Answer:
Stellar black holes form when the center of a very massive star collapses in upon itself.
Answer:
Explanation:
Let the sphere is uniformly charge to radius "r" and due to this charged sphere the electric potential on its surface is given as
now we can say that
now electric potential is given as
now work done to bring a small charge from infinite to the surface of this sphere is given as
here we know that
now the total energy of the sphere is given as
Answer:
<em>The answer is B</em>
Explanation:
<em>I got this from study island</em>
If you are stationary, but in/on a moving vehicle/object you can be at rest and moving at then same time.
<u>Explanation</u>:
- A particle, when viewed from a given frame of reference, cannot be both at rest and in motion. However, in one frame of reference, a particle can be in motion whereas in another frame of reference the particle is in motion.
- For example, if you are seated in a plane, the plane is stationary in that reference frame and the Earth moves under it, but in the reference frame of the Earth, the plane is moving concerning the Earth. When you are standing still on Earth, in your frame of reference, the Earth is stationary, and the Sun and stars move around the Earth.
- However, in the frame of reference of the center of our solar system, the Earth orbits the Sun and the Sun are perturb slightly by the rest of the planets, but the rest of the galaxy orbits our solar system. Of course, in rest from our Galaxy, our solar system orbits a giant black hole at its center.
<span>Correct Answer: D) 6CO2 + 6H20 → C6H12O6 + 6O2</span>
The reactants are Carbon Dioxide (CO2) and Water (H2O) and the products are Glucose (C6H12O6) and Oxygen gas (O2).
In a balanced chemical equation, the number of atoms of each element are same on both left and right hand side of the equation.
In the given options, option D gives the balanced chemical equation and mentions the reactants and products on correct sides of the equation. So the correct answer is Option D
