Ingenuity is a small robotic helicopter deployed to Mars that is planned to make the first rotor-powered flight on any planet beyond Earth. Ingenuity's total mass is 1.8 kg.

The gravitational field strength on Mars is 3.7 N/kg. The gravitational field strength on Earth is 10 N/kg.

What is the difference in gravitational potential energy for the helicopter on Mars compared to Earth for when it is lifted by 10 meters?

Explain how you solved this.

=====================================

explanation

the graph has a slope of 1/3 because each time you move up 1, you go to the right 3. so, slope = rise/run = 1/3. we can cross choice a off the list since we want a slope of 3, rather than 1/3.

the first table shown has a slope of -3. this is because the rise is -6 and the run is 2, so slope = rise/run = -6/2 = -3. note how x increases by 2 each time (run) and y drops by 6 each time (rise). choice b can be eliminated.

the second table has a slope of 3. each time x goes up by 1, the y values increase by 3. slope = rise/run = 3/1 = 3. alternatively you can use the slope formula to prove that the slope is 3 here. use any two rows of values to generate the two points. choice c is one of the answers

the third table also has a slope of 3. let's use the slope formula to prove as such. i'm going to use the first two rows of the table. so i'll use the two points (2,1) and (5,10)

m = slope

m = (y2-y1)/(x2-x1)

m = (10-1)/(5-2)

m = 9/3

m = 3 so we get a slope of 3

choice d is the other answer

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm

not sure but it may be b, as i said i'm not sure.
