Proponents of astrology claim that the positions of the planets at the time of a baby's birth will affect the life of that person in important ways. Some assert that this effect is due to gravity. Examine this claim with Newton's law of gravity. Calculate the maximum force exerted on the baby by the planet Mars and compare that with the force of gravity exerted by the mass of the doctor's head as she delivers the baby. Assume Mars is at its closest approach to Earth at the time. You will need to estimate the mass of a newborn, as well as the mass and distance between the doctor's head and the baby.

1) Determine the distance from the Earth to Mars in meters

2) Calculate the maximum force exerted on the baby by the mass of the doctor's head as she delivers the baby.

3) Calculate the maximum force exerted on the baby by the planet Mars.

i did try to but i still didn't understand it that's why i reposted it

You have to make some assumptions to come up with numbers. First of all, the closest possible approach of Mars to the Earth is 35 million miles or, 5.63*10^10 meters.

You need the mass of Mars. That is 6.42*10^23 kg.

Assume the doctor's head mass is 4 kg and the baby's mass is 4kg, and the separation of the doctor's head is 0.5 meter during delivery.

You will have to look up the value of Newton's universal gravity constant G and crank out some numbers to get the actual forces. The ratio of the doctor's head force to the Mars force will be
(4/6.42*10^23)*(5.63*10^10/0.5)^2 = 0.079

So the gravitational influence of Mars is greater than that of the doctor in this situation, but that does not prove astrology has an important influence.

thank you!

To address this claim using Newton's law of gravity, we need to calculate the maximum force exerted on the baby by the planet Mars and compare it with the force of gravity exerted by the mass of the doctor's head.

1) Determine the distance from the Earth to Mars in meters:
The average distance from Earth to Mars is approximately 225 million km. Since we need the distance in meters, we can convert this distance to meters by multiplying it by 1,000,000. Therefore:
Distance = 225,000,000 km * 1,000,000 m/km = 2.25 * 10^14 meters

2) Calculate the maximum force exerted on the baby by the mass of the doctor's head:
To calculate the force, we need to know the mass of the doctor's head and the distance between the doctor's head and the baby. Let's assume the mass of the doctor's head is 5 kg, and the distance between the doctor's head and the baby is 0.5 meters. Therefore:
Force = (Mass of the doctor's head) * (Acceleration due to gravity)
= (5 kg) * (9.8 m/s^2)
= 49 N

3) Calculate the maximum force exerted on the baby by the planet Mars:
To calculate the force exerted by Mars on the baby, we need to use Newton's law of gravity. The formula for the gravitational force between two objects is given by:
Force = (G * Mass of Mars * Mass of the baby) / Distance^2

The mass of Mars is approximately 6.39 x 10^23 kg. To estimate the mass of a newborn, we can assume it to be around 3 kg. Substituting the values, we get:
Force = (G * 6.39 x 10^23 kg * 3 kg) / (2.25 x 10^14 m)^2

Here, G is the gravitational constant, which is approximately 6.67 x 10^(-11) N(m/kg)^2.

Now, plug in the values and calculate the force exerted by Mars on the baby.

After obtaining both the forces, you can compare them to determine if the force exerted by the doctor's head is larger than the force exerted by Mars, or vice versa. This comparison will provide insight into the relative influences of gravity from these two sources on the baby during delivery.
