I can think of 2 off the top of my head first is friction and second is gravity
Answer:
the answer is mechanical energy
Explanation:
A water wheel converts the kinetic energy of moving or falling water into mechanical energy. This mechanical energy is used for powering the mill.Water wheels have wooden or metal wheels that have buckets or blades attached around them. They are placed in a river or lake. The force of the water rotates the wheel. As the wheel moves, it turns an axle attached horizontally to the wheel. The axle in turn moves the system of gears that operate the functioning of mills. Waterwheels were used for preparing fiber and crushing ore.
Answer:
lets set the ratio -A/HA as R:
pH = pKa + log(R,10) => pKa + log10(R)
pH = 5.5
pKa = 4.76
R => 10^(pH - 4.76)
10^(pH - 4.76) => 5.4954
Given R (-A/HA) a number bigger than 1, then the concentration of -A is bigger than HA
Explanation:
Answer:
2.1 x 10¹²ng
Explanation:
Mass of the calcium carbonate given is:
2.1kg
We need to take this mass to nanogram, ng.
Since :
1000g = 1kg
10⁹g = 1ng
So;
1kg = 1000 x 10⁹ = 10¹²ng
So;
2.1kg will give;
Since
1kg gives 10¹²ng
2.1kg will give 2.1 x 10¹²ng
