HELP PLEASE ILL MARK BRAINLIEST Mr. Newton proposed that F = (G Mearth Mobjet) / r2 where F=Force, G=Universal Gravitational Constant, Mearth = mass of the earth, Mobjet = mass of any object attracted by the earth, r = radius (or distance) between the two mass centers.

But Mr. Newton also proposed that F = m a where F= Force, m=Massobject, and a = acceleration (in the case of when Force is also equal to a Weight, a = acceleration due to gravity).

If we equate the two formulas: m· a = F = (G· Mearth ·Mobjet) / r2

Where m = Massobject we get:

Mobject · a = (G· Mearth ·Mobjet) / r2 or agravity = (G· Mearth) / r2

find the Universal Gravitational Constant (in metric units), the mass of the earth (in kg), and the radius of the earth in m (meters) and use those values to calculate agravity.

Which of the following statements is correct in hour our immune system responds to a potential pathogen? a. the adapted immune system will call on the innate immune system to destroy the pathogen. b. b cells will start reading the antigen code immediately and call t cells to assist in destroying the pathogen. c. the skin will be the first line of defense, and then the many phagocytes in the bloodstream will attempt to consume the possible pathogen. d. the t-cells in the adapted immune systems are the first to recognize the pathogen vaccines are weakened forms of disease causing microorganisms, which are given to patients to prevent disease. after the vaccine is administered, the immune system responds by creating a(n) to recognize the a. antigen, antibody b. antibody, antigen c. antibody, antibiotic d. antibiotic, antibody
