Answer:
A. 1.50
Explanation:
9.01 x 1023 molecules* 1 mol/ 6.022×1023 molecules= 1.49618067087 moles
Rounded would be 1.50
Answer:
A
Explanation:
It is correct please I hope it helps! :)
Highest height : Potential energy = high | Kinetic energy = low
Lower height: kinetic Potential energy = low | Kinetic energy = high
*Remember it by when its higher thats when it has "high potential" :)*
if your serious about this question then it is 5
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
