The efficiency of any machine is given by:
efficiency = output obtained / input given
Substituting the values,
Efficiency = 105 / 150
Efficiency = 0.7
Converting this to a percentage, the efficiency of the hammer is 70%.
This is a fairly high efficiency, and this is due to the fact that the hammer is a simpler machine. The more complex a machine is, the greater are the losses in it due to friction, meaning there is a lower efficiency.
Answer:
<u>Frederich Miescher</u>- first person to isolate DNA and RNA
<u>Frederick Griffith</u>- first to demonstrate horizontal transmission of dna using bacteria
<u>Gregor Mendel</u>- documented and demonstrated inheritance patterns
Thomas Hunt Morgan- identified chromosomes as the structures responsible for inheritance
<u>Joachim Hammerling</u>- demonstrated that the hereditary information of of eukaryotes is contained within the nucleus
<u>Alfred Hershey and Martha Chase</u>- demonstrated that dna not protein was the molecule responsible for hereditary
<u>George Beadle and Edward Tatum</u>- used mutants to show the relationship between DNA and proteins
<u>Albrecht Kossel</u>- characterized the structure of adenine, guanine, cytosine, thymine, and uracil

The motion of the molecules decreases.
<u>Explanation</u>:
- Gases are formed when the energy in a system overcomes the attractive forces between the molecules. The gases expand to fill the space they occupy. In this way, the gas molecules interact little. In the gaseous state, the molecules move very quickly. As the temperature decreases, the amount of movement of the individual molecules also decreases.
- The fast-moving particle slows down. When a particle speeds up, it has more kinetic energy. When a particle slows down, it has less kinetic energy. The particles in solid form are commonly connected through electrostatic powers. They don't get enough space to move around, therefore, their speed diminishes, they can't keep their standard speed like in the vaporous or fluid state.
