if i weigh 100 lbs on earth how much would i weigh on halley's comet?
Were you really assigned this problem or are you just curious?
You need to know both the size of the solid head of the comet (the only place where you could stand), and its mass. The head is not spherical, having an oblong dimension of about 15 x 8 km. The mass is M = 2.2*10^14 kg. Because it is not spherical, your weight will depend upon where you are standing.
For an approximate value of your weight there, in Newtons
use a mean radius of R = 5500 m and the formula
W = G*M*m/R^2
where G is the universal constant of gravity, 6.67x10^-11 N*m^2/kg^2.
m = 45.5 kg is your own mass.
W = 0.022 Newtons
That is about 0.005 lb or 0.08 oz
If you weigh 100 pounds on earth how much would you weigh on halleys comet?
how would standing on a comet affect a person from earths weight and also our comets shooting star or do they just look like shooting star from far away.
Well, let me put it this way: Halley's Comet is known for being quite swift, so maybe it would make you feel lighter from all the speedy excitement! But in terms of actual weight, it's important to note that Halley's Comet doesn't have a solid surface to stand on like Earth does. It's mostly made up of icy dust and gas, so determining your weight there might be a bit tricky. However, if you're feeling adventurous, you could consider packing a space suit and figuring it out for yourself—I'd call that weighing yourself in style!
To determine how much you would weigh on Halley's Comet, we need to consider its gravitational force. Halley's Comet has a significantly smaller mass than Earth, which means its gravitational force is much weaker.
First, let's find out the gravitational acceleration on Halley's Comet. We can do this by using the formula:
g = G * (M / r^2),
where:
g is the gravitational acceleration,
G is the gravitational constant (approximately 6.67430 × 10^-11 N m^2/kg^2),
M is the mass of Halley's Comet, and
r is the distance from the center of Halley's Comet.
The mass of Halley's Comet is estimated to be around 2.2 × 10^14 kg, and its radius is about 5 km (or 5,000 meters). Let's calculate the gravitational acceleration:
g = (6.67430 × 10^-11 N m^2/kg^2) * (2.2 × 10^14 kg) / (5000 m)^2
After calculating, we find that the gravitational acceleration on Halley's Comet is approximately 0.001 m/s^2.
Now, let's determine your weight on Halley's Comet. Weight is calculated by multiplying your mass by the gravitational acceleration. Assuming your mass remains constant at 100 lbs (approximately 45.36 kg), we can calculate your weight:
Weight = mass * gravitational acceleration
Weight = 45.36 kg * 0.001 m/s^2
Therefore, your weight on Halley's Comet would be approximately 0.04536 N or 0.01 pounds. Keep in mind that this weight is greatly reduced due to the weak gravitational pull of Halley's Comet.
