Answer:
20N
Explanation:
Given parameters:
Force(N) Acceleration(m/s²)
10 0.2
? 0.4
Unknown:
The force applied when the acceleration is 0.4m/s²
Solution:
From newton's second law of motion;
Force = mass x acceleration
Since we are using the same box, let us find the mass of the box;
Force = mass x acceleration
10 = mass x 0.2
mass = = 50kg
Now,
The force in the second instance will be;
Force = 50 x 0.4 = 20N
Answer:
The answer is
<h2>1.45 g/mL</h2>Explanation:
The density of a substance can be found by using the formula
From the question
mass of material = 5.01 g
volume = 3.46 mL
The density of the material is
We have the final answer as
<h3>1.45 g/mL</h3>Hope this helps you
