Hydrogen gas is harmless to your feet so since you don’t need protection against it that seems the best answer.
Answer:
Four fundamental forces are gravitational, electromagnetic, strong, and weak.
Explanation:
The gravitational and electromagnetic interactions, which produce significant long-range forces whose effects can be seen directly in everyday life and the strong and weak interactions, which produce forces at minuscule, subatomic distances and govern nuclear interactions.
Ill save you all the math steps, but here is the answer! <span>102.25m I took that physics exam 3 days ago! So if you need the steps just ask Ill insert them in!</span>
Weight equals mass times gravitational acceleration=400N, so mass=400/9.8=41kg approx.
The pet store would be the reference point because it is where he started and it will not move. Hope this helped.
