The answer to this question would be: F1/F2=2
Gravitational force is directly related to the mass of the object but inversely related to the quadratic of the distance to the object. In this case, the planet2 has twice the mass and twice the distance. Then, the ratio of the gravitational force compared to planet1 should be:
F1/F2
(GMm/r^2)/(GM*2m/2r^2)
(m/r^2)/(2m/4r^2)
1/(1/2)= 2
Answer:
454,320 joules
Explanation:
The work done on an object is equal to its change in kinetic energy: Change in KE = F × d.
Plug the values for F and d into the formula and solve:
Change in KE = 2,524 × 180
= 454,320 joules
The roller coaster gains 454,320 joules of energy from the work done on it by the chain.
The answer is A. <span> the state and local authorities. :) </span>
Answer:
T = 273 + (-50) = 273 – 50 = 223 K
R = 188.82 J / kg K for CO2
Density (Martian Atmosphere) = P / RT = 900 / 188.92 x 223 = 900 / 42129.16 = 0.0213 kg /
T = 273 +18 = 291 K, R = 287 J / kg k (for air) P = 101.6 k Pa = 101600 Pa
Density (Earth Atmosphere) = P / RT = 101600 / 287 x 291 = 1.216 kg /
