Question

3. The drawing below shows a space buggy on the surface of Mars.





























The weight of the buggy was 105 N on Earth and 40 N on Mars.



a. Why was the weight of the buggy less on Mars than on Earth?



b. The buggy uses solar panels to generate electrical energy.

The solar panels generate less electrical energy on Mars than on Earth. Give a reason why?



c. The weight of the buggy was 40 N on Mars. When the buggy landed on Mars it rested on an area of 0.025 m2.Calculate the pressure exerted by the buggy on the surface of Mars. Give the unit.​

Answer 1

Answer:

a. it is because the difference of the gravitational pull in compare to earth

the gravity of mars is less as w = mass*gravity

b.it is happening due to the distance of sun from earth is less and the distance is greater of sun from mars so the closer the object is to sun the more energy it will create

c.

Pressure = Force / Area

Pressure = 40N / .025 m^2

Pressure = 1600 Newtons per Square Meter

Explanation:

Answer 2

(a) Since Mars has less mass the earth, the surface gravity on Mars is less than the surface gravity on Earth. The surface gravity on Mars is only about 38% of the surface so if you weigh 100 pounds on earth, you would weigh only 38 Pounds on Mars.
