Time= 20 minutes= 20*60=1200 s
Charge=current*time=12*1200=14400 C
Answer:
A. Chemical change
Explanation:
When vinegar and baking soda are first mixed together, hydrogen ions in the vinegar react with the sodium and bicarbonate ions in the baking soda. The result of this initial reaction is two new chemicals: carbonic acid and sodium acetate.
1. radiation
2. convection
3. condunction
Answer:
The viscosity of a liquid is a measure of its resistance to flow. Water, gasoline, and other liquids that flow freely have a low viscosity. Honey, syrup, motor oil, and other liquids that do not flow freely, like those shown in Figure 1, have higher viscosities. We can measure viscosity by measuring the rate at which a metal ball falls through a liquid (the ball falls more slowly through a more viscous liquid) or by measuring the rate at which a liquid flows through a narrow tube (more viscous liquids flow more slowly).
Hello,
This is true. Net force can be calculated using the equation F = ma, where f is net force, m is mass, and a is acceleration. Simply multiply mass and acceleration to obtain the net force being exerted on the object.
True
Hope this helps!
