Two particles are separated by 0.38 m and have charges of -6.25 x 10-9C and 2.91 x 10-°C. Use Coulomb's law to predict the force between the
particles if the distance is doubled. The equation for Coulomb's law is
F kanga, and the constant, k, equals 9.00 x 109 Nm2/C2.
A. -2.83 x 10-7N
B. 2.83 x 10-7 N
C. -1.13 x 10-6N
O D. 1.13 x 10-6N

it's unlikely a majority of a large population would agree on issues

hope this : )

answer: - b cells

explanation: -

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.

it would lead to upper respiratory infections and pneumonia.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
