Answer:
b
Step-by-step explanation:
Mars radius = 3,393 km
Mars Mass = 6.42 x 10^23 kg
Earth Radius = <span>6,371</span><span> km
Earth Mass = </span><span>5.97237×10<span>^24kg
Gravity is directly proportional to mass and
Gravity is inversely proportional to the square of the distance.
So, we can come up with this equation:
Force = Mass / radius^2
Force Earth = 5.97237 x 10^24 / 6,371^2
Force = </span></span><span>1.471 x 10^17
Force Mars = 6.42 x 10^23 / 3,393^2
Force = 5.577 x 10^16
Earth's gravity vs Mars' Gravity = </span>1.471 x 10^17 / <span><span>5.577 x 10^16
</span>= 2.64
Earth has 2.64 times the gravitational attraction that Mars has.
</span>So, you would weigh 834 / 2.64 =
316 Newtons on Mars.
Answer: 256
Step-by-step explanation:
So first we find the change
45 to 15=45-15=30
change is 30
rate of change=(change)/(original)
original=45
change=30
30/45=10/15=2/3=0.66666666=66%
rate of change is 66.66%
