V = IR
I = V/R
I = 12/6
I = 2 amps
Answer:
He is incorrect. Dissolving salt in water and evaporation of the water are both physical changes. The reappearance of salt is evidence that the change was reversible by a physical change, so it could not be a chemical change.
<span>There are several main pieces of evidence that support the Big Bang theory.
One is the fact that the universe is expanding, proven with something
called red shift. The second is something called cosmic microwave
background radiation. The third is the abundance of different elements
in the universe.

Answer:
Explanation:
If we assume the balloon to be a constant pressure device and the gas filling it to be ideal.
pV = nRT
p, n and R are all constants so
V is directly proportional to T (which must be in Kelvins)
1.8/1.5 = (T + 273)/(25 + 273)
T = 84.6
T = 85°C
Distance is measurable velocity is the speed of something and acceleration is the capacity to gain speed within a short amout of time
EXAMPLES
distance how far utah is from california
velocity the time it take you to run home
acceleration is like how soon a car reaches 25 mph
