Answer:
mineral
Explanation:
Limestone is a sedimentary rock . Chemically it belongs to carbonate group and its chemical formula is CaCO3. Its major component are calcite and aragonite
It is formed by the skeletal remains of marine like coral and molluscs. It
Calcite is a mineral with its chemical formula as calcium carbonate(CaCO3). It can be mostly found in igneous, metamorphic and sedimentary rock. calcite is one of the component of limestone.
Now we can easily deduce the analogy.
Just like limestone is a type of rock . Calcite is type of mineral.
Answer:
1. True.
2. False.
Explanation:
In Science, energy can be defined as the ability of an object or body to do work. The various forms of energy are solar energy, electrical energy, chemical energy, thermal energy, wind energy, nuclear energy etc.
The Law of Conservation of Energy states that energy cannot be destroyed but can only be transformed or converted from one form to another.
An electromagnet can be defined as a soft metal core such as iron that is surrounded by a coil of wire and is magnetized through the passage of an electric current.
The energy conversion or transformation forms in an electromagnet is described below;
1. True: The energy transformation in an electromagnet is from chemical to electrical to electromagnetic waves.
2. False: The energy transformation in an electromagnet is mechanical energy to electrical energy to chemical energy. Actually, it is from chemical energy to electrical energy and lastly electromagnetic energy (mechanical).
Show the importance of education in advancing a more equal society I believe.
