-(2)/(3)\cdot12(3)/(8)=-(2)/(3)\cdot(12\cdot8+3)/(8)=-(2)/(3)\cdot(99)/(8)\n\n=-(1)/(1)\cdot(33)/(4)=\boxed{-(33)/(4)}=-(32+1)/(4)=\boxed{-8(1)/(4)}

where G is a constant and M is the mass of the earth. Calculate the work done by the force of gravity on a particle of mass m as it moves radially from 7500 km to 9400 km from the center of the earth.

Answers

Answer:

-2.0213* 10^(-7)GMm\text{ J}

Step-by-step explanation:

Since, the force of gravity is,

F = -(GMm)/(r^2)

Where,

G = gravitational constant,

M = mass of earth,

m = mass of the particle,

r = distance of particle from centre of the earth,

∵ 7500 km = 7.5* 10^6 meters

9400 km = 9.4* 10^6 meters

Thus, work done by the force of gravity,

W=\int_(7.5* 10^6)^(9.4* 10^6)F. dr

=-\int_(7.5* 10^6)^(9.4* 10^6)(GMm)/(r^2)dr

=GMm[(1)/(r)]_(7.5* 10^6)^(9.4* 10^6)

=GMm((1)/(9.4* 10^6)-(1)/(7.5* 10^6))

=GMm((7.5-9.4)/(9.4* 10^6))

=-GMm((1.9)/(9.4* 10^6))

\approx -2.0213* 10^(-7)GMm\text{ J}

Where,

G = 6.67408* 10^(-11) \text{ }m^3 kg^(-1) s^(-2)

M=5.972* 10^24 \text{ kg}

A physics lab group was conducting an experiment to determine the length of a spring when different objects of varying weight were hung from it. After testing ten different objects, the group calculated the following linear regression where x is the weight of the object in ounces and h(x) is the length of the spring in centimeters: h(x)= 2.3x+15.5. What does y-intercept of this equation indicate about the relationship between object weight and the length of the spring?1) When there is no object on the spring, its length is 2.3 cm2) When there is no object on the spring, its length 15.5 cm3) For every ounce of weight, the spring length increases by 2.3 cm4) For every ounce of weight, the spring length increases by 1535 cm
