Calculate the value of the current through the point. I=Q/t = 1C/20s = .05C/s= .05 A x10^-3 C = 50mA 2.A total charge of 2.5 × 10-3 C passes a point every 40 seconds. Calculate the value of the current through the point. I=Q/t =0.0025C/40s= 6.25 C/s = 6.25 A 4.A total charge of 50 × 10-3 C passes a point

We will look closely at the problem of induction‚ and 20th century philosopher Karl Popper’s solution to this problem‚ and

In chapter 11‚ we learned about DNA and Genes (11.1DNA: The Molecule of Heredity; 11.2From DNA to Protein; 11.3Genetic changes). DNA (deoxyribonucleic acid)‚ which is in a shape called a double helix‚ developed its name from the simple sugar in DNA (deoxyribose). The phosphate group is composed of one atom of phosphorus surrounded by four oxygen atoms. A nitrogen base is a carbon ring structure that contains one or more atoms of nitrogen. Next to cover is DNA replication in which enzyme breaks

Chapter 11 Questions to be graded: 5. Were the experimental and control groups similar in their type of feeding? Provide a rationale for your answer. Answer: Yes the experimental and control groups are similar in their feeding type because 40.6% in the experimental group decided to breast-feed‚ and 41.7% in the control group decided to breast-feed‚ that’s only 1.1% difference. 53.1% of the experimental group bottle-fed while 50.0% of the control group bottle-fed‚ a small 3.1% difference.
