Answer:
They are able to balance torques due to gravity.

Explanation:
When two friends of different masses will balance themselves on see saw then at equilibrium position the see saw will remain horizontal
This condition will be torque equilibrium position where the see saw will not rotate
Here we can say

here we know that force is due to weight of two friends
and their positions are different with respect to the lever about which see saw is rotating
since both friends are of different weight so they will balance themselves are different positions as per above equation
Answer:
1:knowledge of the structure of DNA
2:an understanding of hemoglobin
4:ground fault circuit interrupters
7:aerogel
Explanation:
Answer:
The nervous and endocrine systems exert the ultimate control over homeostasis because they coordinate the functions of the body's systems.
Explanation:
Answer:
The correct answer is the second option
Explanation:
The formula in question (for gravitational force) is provided below
F = G.m₁.m₂/r²
Where
F = force of gravity
G = gravity constant (6.674 × 10⁻¹¹ m.kg⁻¹.s⁻²)
m₁ and m₂ = are the masses of the objects
r² = distance between the centers of the two objects
From the above, <u>it can be deduced that m₁ and m₂ are masses and hence can only be positive. Positives multiplied together only gives positive, thus the second option is correct.</u>
You would benefit from your own handled problem because you solved a problem you had.
i’m pretty sure that’s it, going off the info i had.
