How did stanley miller’s experiment in 1953 influence scientific thinking about the origin of life?
a.
it showed that radiometric dating could be used to accurately determine the age of fossils.
b.
it proved that the atmosphere of the early earth contained ammonia and methane.
c.
it proved that organisms could evolve by the process of natural selection.
d.
it showed that the chemicals of life could form in the conditions found on the early earth.

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.

Suppose an objects initial velocity is 10m/s and it’s final velocity is 4 m/s. mass is constant. what can best be concluded about the object based in the work-energy theorem

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
