They provide information about the pasts of the animal and plants.
The phrase that energy stays conserved in an energy transformation is based on the fact that energy can not be created or destroyed. Example, in a simple pendulum, the bob does a to-fro motion. When the bob goes up it becomes stationary for a second and then comes down at some speed. Here the potential energy of the bob at the highest point undergoes transformation into kinetic energy at motion. Due to the fact that energy is conserved it keeps on performing the oscillatory motion.
Answer:
Momentum of truck = 85000 kgm/s
Of car = 56400 kgm/s
Total is 141400kgm/s.
Explanation:
Momentum = mass X velocity
I think it’s B, just a guess but I need points I am a small child and I am not smart
While examining a cell under transmission electron microscope, it is observed that the high density of ribosomes present in the cytoplasm produces large amounts or protein molecules. Ribosome contains rRNA and proteins. rRNA directs the catalytic process of protein synthesis.
The messenger RNA or mRNA that have the coding sequences exits from the nucleus and enters the ribosome and gets translated to form proteins. The transfer RNA or tRNA relocates amino acids from nucleus to the ribosome.
