Answer:
Citric
Explanation:
Citric and acetic acids are naturally found in foods and can be safe to eat.
Answer:
v = 40 m / s
Explanation:
Let's use the expressions for accelerated motion
v = v₀ + a t
where vo is the initial velocity, at the acceleration and t is the time.
as the body starts from rest its initial velocity is zero
v = 0 + at
let's calculate
v = 8 5
v = 40 m / s
Explanation:
A molecule can be made up from same or different elements. Whereas a compound will have different atoms.
Therefore, the difference between a molecule and a compound is that a compound is made up of atoms from different elements.
For example, 
is a molecule and NaCl is a compound.
And a chemical change creates a new substance.
Answer:
Explanation:
When coefficient of friction is approximately zero then we have
here we know that
R = 30 m
now when friction coefficient is 0.30 then we have
now we have
Answer:
Diffusion
Explanation:
Diffusion can be defined as the mixing of different gases by random molecular motion and with frequent collisions.
It is a process whereby gas particles move from an area of higher concentration to an area of lower concentration due to constant random motion.
This would cause the gases to mix up gradually and then form an homogeneous mixture.
