Explain the law of motion needed to solve this problem and then solve it. On Planet Zorg, a 30 kg barbell can be lifted by only
vladimir2022 [97]
Law of Motion says that every object that moves uniformly tends to stay in that state unless a force is applied to it. Force is equal to the mass of that object multiplied by its acceleration:
F = m × a 
The unit of force is N = kg * m/s².

Q1: T<span>he acceleration of gravity on Planet Zorg is unknown:
a = ?

</span>We know:
F = 180 N
<span>m = 30 kg
</span><span>
Since F = m </span>× a, then:
a = F/m
a = 180 N/30kg
a = 180 kg*m/s² / 30 kg
a = 6 m/s².
So, the acceleration of gravity on Planet Zorg is <span>6 m/s².

Q2: Force needed to change the motion of the object on the Earth is unknown:
F = ?

We know:
a = 9.8 </span><span>m/s²
m = 30 kg

If F = m </span>× a, then:
F = 30 kg × 9.8 m/s²
F = 294 N
So, f<span>orce needed to change the motion of the object on the Earth is 294 N.</span>

When women are in labor, the uterus contracts more and more strongly by the actions of a peptide hormone messenger. This scenari
zheka24 [161]

Answer:

The correct answer is -  a positive feedback loop

Explanation:

Oxytocin is a peptide hormone that is released during labor in women which contracts the uterus and n increase of the oxytocin causes more release of oxytocin hormone to increase the contraction more strongly.

Oxytocin shows a positive feedback loop as its release leads to more of the oxytocin release by stimulates its more release. Most of the hormones show negative feedback release.
