Question

which has more mass, a kilogram of feathers or a kilogram of iron?○ neither - they have the same mass○ the iron○ the feathers4multiple choice 20 pointsthe acceleration of gravity on earth is about $10\\,m/s^2$. if i have a mass of 35 kg, what is my weight on earth?○ 45 n○ 25 n○ 350 n5multiple choice 20 pointsyou are standing on the earth. which object is exerting a gravitational pull?○ the earth○ you and the earth○ you

Explanation:

Step1: Analyze mass comparison

Both are 1 kilogram, so mass is equal.

Step2: Calculate weight using $W=mg$

Given $m=35\ \text{kg}$, $g=10\ \text{m/s}^2$.
$W = 35 \times 10 = 350\ \text{N}$

Step3: Apply Newton's third law

Gravitational pull is mutual between two objects.

Answer:

1. neither - they have the same mass
2. 350 N
3. you and the earth
