All cells are surrounded by a Cell Membrane
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:
1.) true
2.) False
Explanation:
1.) it does keep the prices inside the cell.
2.) proteins and phospholipids make up most of the membrane.
Hope this helps!
The answer would be A.
hope this helped :)
