Answer:
Mitosis is a type of cell division in which a parent cell divides into two identical daughter cells, each with the same number and kind of chromosomes as the parent cell.
When a parent cell divides more times than usual during mitosis, the division of chromosomes between the chromosomes would not be proper. For example, a daughter cell may end up with one chromosome less than the parent cell. This ultimately results in genetic disorders.
Batteries convert chemical energy into electrical energy. It is able to store electrical energy in the form of chemical energy.
Have you ever seen the two different sides of a battery? One side is often labelled with a positive sign, and the other with a negative sign. Inside the battery are four cells where two processes take place. One process uses electrons, and the other creates electrons. When the electrons flow, it creates electricity.
Drums convert mechanical energy into sound energy.
When a musician bangs his/her drumstick on the drum, the motion makes a sound. This movement turned motion into sound.
Answer: option d. gives the percentage of water molecules in the air.
Explanation:
Answer: a) 5 x 10^5 kg/s b) 444 MW
Explanation:
Kinetic energy per unit mass Ke is
Ke = V^2 / 2
Ke = 3^2 / 2 = 4.5 J/kg = 0.0045 kJ/kg
Now potential energy per unit mass Pe is
Pe = g x z = 9.8 x 90 = 882.9 J/kg = 0.8829 kJ/kg
The total mechanical energy of the River per unit mass e = Ke + Pe = 0.0045 + 0.8829 = 0.88744 J/kg
M = P x V = 1000 x 500 = 5 x 10^5 kg/s
b) power generation potential of the entire river at the location Wmax = Emech = M x Emech = 500,000 x 0.88744 = 444,000kW = 444MW
