Please help me. None of the above is the correct answer and I need urgent help. Thanks a lot!!!
Average mass of 1 person = 80 kg
No. of persons = 3.0 million = 10^6
mass of the total person, M = 80 x 10^6 kg
mass of the eagle, m = 5.5 kg
Distance between the group of people and the eagle, R = 270 m
Gravitational force between the group of people and the eagle,
F = G*M*m / R^2
where, G = Universal gravitational constant = 6.674 x 10^-11 m^2 / kg^2
Therefore,
F = (6.674 x 10^-11 x 80 x 10^6 x 5.5) / 270^2
= 4.028 x 10^-2 x 10^-5
= 0.4028 x 10^-6 N = 0.4028

Problem 1. (1 point) A steel ball weighing 128 pounds is suspended from a spring. This stretches the spring 178 feet. The ball is started in motion from the equilibrium position with a downward velocity of 6 feet per second. The air resistance (in pounds) of the moving ball numerically equals times its velocity (in feet per second)...

You may want to reference (Pages 744 - 750) Section 17.5 while completing this problem. Part A From the value K; = 1.2 x 10 for Ni(NH3 )e2+, calculate the concentration of NH, required to just dissolve 0.024 mol of NiC204 (Ksp = 4 x 10-19) in 1.00 L of solution. (Hint: You can neglect the hydrolysis of C,0, because the solution will be quite basic.) Express your answer using two significant figures. VOAD ?...

Part 4 Some studies have shown that physical activity has many benefits for mental health. The director of health care planning in a local hospital thinks that if he introduced exercise based therapy for people admitted with depression, this may reduce hospital costs by reducing the likelihood of these patients being re- admitted to the hospital. However, before introducing exercise based therapy for all patients with depression he wanted...
