A certain machine can output 50 Joules (J) of energy when 100 J of energy are input. If the amount of friction experienced by th
Dmitriy789 [7]

Explanation:

D) 75 J

Energy is neither related nor destroyed- it's simply converted to different forms. Forces are vectors with both mass and acceleration; they are interactions that have the ability to change an object's motion. As objects move, their potential energy (apprx 100 J) is converted to kinetic energy. However, friction a resistive force, which is formed from the conversion of an object's kinetic energy into heat energy, as two surfaces move along each other.

With the reduction of friction, the energy output should increase, as less energy is lost as heat. Thus, the output should be 75 J.

Tems11 [23]

Answer:

If radioactive deoxythymidine triphosphate (dTTP) is added to a culture of rapidly growing bacterial cells,  you will find the greatest concentration of radioactivity in the Nucleoid.

Explanation:

Deoxythymidine triphosphate (dTTP); is one of the four nucleoside triphosphates that are used in the in vivo synthesis of DNA. Unlike the other deoxyribonucleoside triphosphates, thymidine triphosphate does not always contain the "deoxy" prefix in its name
