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
exerting a force of 180 N. What is the acceleration of gravity on Planet Zorg? Predict how the motion of this object would change if on Earth. Please help. I have no idea how to do this.
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>
There are two genes here represented different alleles (Yy & Ss). According to Mendelian law, the principle of independent assortment applies to mean each allele has equal chances of ending up in a gamete. Therefore each gamete can have either allele of the two genes as shown in the punnet square. The combinations of the offspring are therefore numerous.
