Answer:
Force, F = 68.93 pounds
Step-by-step explanation:
Given that,
Mass of the astronaut, m = 80.70 kg
Acceleration due to gravity on Mars, 
The force acting on him is given by using second law of motion as :


F = 306.66 N
Since, 1 newton = 0.224 pound
F = 306.66 N = 68.93 pounds
So, 68.93 pounds force she exerts on the martian surface. Hence, this is the required solution.
X = 30 because the ratio of 27/45 = .6 so 18/.6 is 30
She can expect to pick a black marble 125 times
It is B bc the slope would be 2/1 witch equals 2
