Answer:
Newton's 2nd Law says the acceleration of an object depends on its <u>mass </u>and the amount of <u>net force</u> acting on it.
Explanation:
Definition of acceleration:
The acceleration is rate of change of velocity of an object with respect to time.
Formula:
a = Δv/Δt
a = acceleration
Δv = change in velocity
Δt = change in time
Units:
The unit of acceleration is m.s⁻².
Acceleration can also be determine through following formula,
F = m × a
a = F/m
This is the newton's second law:
"The acceleration of an object depends on its <u>mass </u>and the amount of <u>net force</u> acting on it"
The acceleration is depend directly on the force while inversely on the mass.
Sulfur will float, and iron will sink because each will retain its properties.
“Iron will float, and sulfur will sink because each will lose its properties” is <em>incorrect</em>. A substance will lose its properties only if it reacts to form a new substance.
“Both will float because they are physically mixed” is <em>incorrect</em>. The substances in a mixture retain their properties.
“Both will float because they react chemically” is <em>incorrect</em>. Iron and sulfur do not react at room temperature. Even if they did, the iron sulfide would sink.
1 liter= 1,000,000 microliters
20 mL= 20,000 microliter
I hope this helped ;)))
