Answer:
42) 76
b)70
Explanation:
52) because you don't want to confuse different units. one ex)1cm is 1/ 100 of a meter
55) 1 km=1,000 meters
b) 10 decimterers = 1 meter
56)The SI standard for length is the meter the standard for volume is the cubic decimeter
ex) 1cm³=1mL
57) The two scales are the same. but there are no negative temperatures in Kelvin. 0 Kelvin is the lowest temperature possible.
0 Kelvin= -274.5 Celsius
This follows Boyles law which relates pressure and volume. The law states that pressure is inversely proportional to volume at a constant temperature.
PV = k
where k is a constant.
At two instances ;
P1V1 = P2V2
where parameters for the 1st instance is on the left and parameters for the second instance is on the right.
37.5 kPa x 41.3 L = 13.8 kPa x V2
V2 = 37.5 x 41.3 / 13.8
V2 = 112.23 L
At the new pressure gas will take up a volume of 112.23 L
I know calcium helps with the generation of APs as well as sodium and potassium. I would have to say sodium-potassium pumps, but I could be incorrect.
Kinetic energy=Ek
Ek=(1/2)mv²
Ek=480 J
v=8 m/s
mass=?
Ek=(1/2)mv²
480 J=(1/2)m(8 m/s)²
480 J=(32 m²/s²) m
m=(480 J)/(32 m²/s²)=15 kg
answer: the mass of the object is 15 kilograms.
Answer:
See below
Explanation:
When a strip of zinc metal is placed into a blue solution of copper(II) nitrate, a reaction immediately begins as the zinc strip begins to darken. If left in the solution for a longer period of time, the zinc will gradually decay due to oxidation to zinc ions.
