Planet Estimated Mass of Planet (10²³ kg)
W=6.4
X =3.3
Y= 59.7
Z= 48.7
Assuming these planets were similar in radius, which planet would an object weigh the most? (1 point)
A. on planet W
B. on planet Z
C. on planet Y
D. on planet X
To determine which planet an object would weigh the most, we need to find the planet with the highest mass. Looking at the given estimated masses of the planets:
W = 6.4 * 10^23 kg
X = 3.3 * 10^23 kg
Y = 59.7 * 10^23 kg
Z = 48.7 * 10^23 kg
Out of these options, planet Y has the highest estimated mass, 59.7 * 10^23 kg. Therefore, an object would weigh the most on planet Y.
Thus, the correct answer is C. on planet Y.
To determine which planet an object would weigh the most, we need to compare the gravitational forces exerted by each planet. The gravitational force can be calculated using the formula:
F = (G * m1 * m2) / r^2
where F is the gravitational force, G is the gravitational constant (approximately 6.674 x 10^-11 m^3 kg^-1 s^-2), m1 and m2 are the masses of the two objects, and r is the distance between the two objects (in this case, the radius of each planet).
Since the radii of the planets are assumed to be similar, we can ignore the distance factor and focus solely on the masses. Comparing the masses (given in 10^23 kg):
W = 6.4
X = 3.3
Y = 59.7
Z = 48.7
The planet with the highest mass, therefore exerting the strongest gravitational force, is planet Y, with an estimated mass of 59.7 x 10^23 kg.
Therefore, the correct answer is:
C. on planet Y
To determine which planet an object would weigh the most on, you need to compare the surface gravity of each planet. The surface gravity of a planet is determined by its mass and radius.
The formula for surface gravity is:
g = G * (M / R^2)
Where:
- g is the surface gravity
- G is the gravitational constant (approximately 6.674 x 10^-11 N m^2 / kg^2)
- M is the mass of the planet
- R is the radius of the planet
Since we are assuming that the radii of all the planets are similar, we can disregard the radius and only compare the masses.
Calculating the surface gravity for each planet:
Planet W:
gW = G * (MW / RW^2)
Planet X:
gX = G * (MX / RX^2)
Planet Y:
gY = G * (MY / RY^2)
Planet Z:
gZ = G * (MZ / RZ^2)
Comparing the masses given:
MW = 6.4 * 10^23 kg
MX = 3.3 * 10^23 kg
MY = 59.7 * 10^23 kg
MZ = 48.7 * 10^23 kg
Since all the planets have the same radius, we don't need to consider it for this comparison.
Now, substitute the known values into the equations for surface gravity and compare the results:
gW = G * (6.4 * 10^23 kg / RW^2)
gX = G * (3.3 * 10^23 kg / RX^2)
gY = G * (59.7 * 10^23 kg / RY^2)
gZ = G * (48.7 * 10^23 kg / RZ^2)
Since we don't have the specific values for the radii (RW, RX, RY, RZ), we cannot calculate the exact surface gravity for each planet. Therefore, without additional information, we cannot determine which planet an object would weigh the most on.
