Before mitosis, the chromosomes are copied. They then coil up, and each chromosome looks like a letter X in the nucleus of the cell. The chromosomes now consist of two sister chromatids. Mitosis separates these chromatids, so that each new cell has a copy of every chromosome
Answer:
Explanation:
As we know that moment of force is given as
now we have
now from above formula we have
here we know that
so we have
Approximately 150-200 species.
When heat energy is transferred from direct contact between a warm and a cold object , it is known as heat transfer by conduction.
In conduction, the heat transfer takes place within an object or between two objects in contact until the temperature becomes uniform. this kind of heat transfer continues until the temperature at two ends between which the heat transfer take place , becomes equal. Heat transfer takes place from point at high temperature to point at lower temperature.
Answer:
4.62 s
Explanation:
We are given that
Initial angular speed,
Substitute the values
Hence, the wheel takes 4.62 s to come to rest.
