What is the chloroplast structure?

The structure of these organelles is as follows,

Chloroplasts are limited by an outer membrane and an inner one.

In between the two membranes, there is a space left called intermembrane space.

In the interior of the inner membrane, there is another space known the stroma.

Within the stroma, there is the third system of membranes, known as thylakoids.

Thylakoids are disk-shaped structures limited by a membrane, and in their interior, there is a space named thylakoid space.

These structures are arranged as piles, receiving the name of grana. Grana connects by a larger thylakoid membrane.

The photosynthetic pigments are placed in the thylakoids, where occurs light-dependent reactions.

According to this description, the membrane that forms a compartment inside the stroma is the thylakoid membrane.

A car with a mass of 1,324 kilograms, traveling at a speed of 20 meters/second, crashes into a wall and stops. What is the kinetic energy after this perfectly inelastic collision?

Answers

The kinetic energy of a car with a mass of 1,324 kilograms, traveling at a speed of 20 meters seconds is 264800J.

How to calculate kinetic energy?

The kinetic energy of a moving car can be calculated using the following formula:

K.E = ½ × m × v²

Where;

K.E = kinetic energym = mass v = velocity

K.E = ½ × 1324 × 20²

K.E = 264800J
