Answer:
a= 0.2m/s²
Explanation:
Fnet = ma
20 = 100a (divide both sides by 100)
a = 0.2m/s²
Answer:
A solid (s) magnesium strip or ribbon is added to hydrochloric acid, an aqueous solution (aq) . The reaction produces aqueous magnesium chloride and gaseous (g) hydrogen gas, which as you can see bubbles out of solution.
Answer: if this is true or false, then this is false, something that is cold has slow moving particles, fast moving ones generate heat which will make it warm, this object has potential energy not kinetic.
The International Bureau of Weights and Measures is the society that scientist form to bring about one universal system of measurements.
<u>Explanation:</u>
Every theoretical assumptions should be proved experimentally and for that we need a specific system to measure or quantify parameters used in those experiments or the outcome results variables.
The measurements of length should be done by measuring them in meters only and not by liters. The physical properties of every materials should have a particular way of measuring them and this is decided by the International Bureau of Weights and Measures.
They also decide the units of each measurements and the standardization of each units and weights are also done by this society.
