Answer:
True
Explanation:
On the Mohs hardness scale, Quartz is a 7, therefore it should be able to scratch through any minerals numbered 1 through 6
Answer:
, where m is the mass of the pendulum
Explanation:
As we know that mechanical energy is the sum of kinetic energy and potential energy.
Since the Pendulum at its highest point has zero velocity, its kinetic energy at this point is equal to zero.
Thus, here in this mechanical energy will be equal to the potential energy only.
Potential energy is equal to the product of gravity constant, mass of the body and the height of the pendulum
Thus,
Hence,
Answer:
Your body has different kinds of cells. Though they might look different under a microscope, most cells have chemical and structural features in common. In humans there are about 200 different types of cells and within this cells there are about 20 different types of structures or organelles.
