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>
Answer:
Explanation:
Aquifers are groundwater reservoirs often tapped by wells. Water: Water is pretty darn important for living things.
It would change the way that it was written as a formula
Answer:
The earliest time that life forms first appeared on Earth is at least 3.77 billion years ago, possibly as early as 4.28 billion years, or even 4.5 billion years; not long after the oceans formed 4.41 billion years ago, and after the formation of the Earth 4.54 billion years ago.
Explanation:
Explanation:
Silent mutations occur when the change of a single DNA nucleotide within a protein-coding portion of a gene does not affect the sequence of amino acids that make up the gene's protein.
