Answer:
C. Chemical energy
Explanation:
The different types of energy listed in this question are:
A) Electrical energy: it is the energy related to the flow of electrical charges (current)
B) Nuclear energy: it is the energy contained in the nuclei of the atoms, and released during nuclear reactions
C) Chemical energy: it is the energy contained in the bonds between molecules, and it is released during chemical reactions
D) Thermal energy: it is the energy associated with the motion of molecules
Photosynthesis is the process that plants use to transform the light energy (coming from the Sun) into chemical energy. In fact, in this process, plants absorb CO2 (from the atmosphere) and solar energy (from the light), and they convert them into sugars (glucose) and oxygen. Therefore, the initial energy coming as solar energy is converted into energy of the bonds of the molecules of glucose (so, chemical energy).
So, the correct option is C).
Birds exhibit mainly internal development.
Answer:
The ratio of moment of inertia of larger sphere to that of smaller sphere = 4
Explanation:
The moment of inertia of solid sphere is given by I = 2/5MR² where M = mass of sphere and R = radius of sphere.
Radius of smaller sphere = D/2
Radius of larger sphere = 2D/2 = D.
Moment of inertia of smaller sphere I₁ = 2/5M × D²/4 = MD²/10
Moment of inertia of larger sphere I₂ = 2/5M × D² = 2MD²/5
The ratio of moment of inertia of larger sphere to that of smaller sphere = I₂/I₁ = 2MD²/5 ÷ MD²/10 = 10 × 2/5 = 4
Answer: An object at rest has no kinetic energy, but it may have potential energy resulting from its location or structure.
Explanation: To find the answer, we need to know more about the kinetic and potential energies.
<h3>What is kinetic energy of a body?</h3>
- Kinetic energy is a form of mechanical energy possessed by a body by virtue of its motion.
- Kinetic energy of a body of mass m moving with a velocity v is given by,
<h3>What is potential energy?</h3>
- Potential energy is a form of mechanical energy possessed by a body by virtue of its position in the field or configuration.
- PE is always associated with a conservative force.
- There cannot be potential energy due to frictional or viscous forces.
Thus, we can conclude that, an object at rest has no kinetic energy, but it may have potential energy resulting from its location or structure.
