Answer:
Potential energy is energy due to an object's height above the ground.
Potential energy = mass x gravity x height
Kinetic energy is energy due to the motion of the object.
Kinetic energy = 1/2 x mass x velocity²
Answer:
⇒D_AB= 1.21×10^(-9)
Explanation:
Wike chang equation is given as:

Where
D_AB= diffusivity of chlorine in water
Φ= 2.26 for water as solvent
ν= 0.0484 for chlorine as solute
M_B = Molecular weight of water
τ= temperature=289 K
μ= viscosity = 1.1×10^{-3}
Now putting these values in the above equation we get

⇒D_AB= 1.21×10^(-9)
Answer:
2
Explanation:
#1 is incorrect as there is no upward force that would balance the 5 N downward force
#3 is incorrect 2 is less than 5 = net force downward of 3 N
#4 is incorrect 5 is greater than three = 2 N net force going to the left and 2N going up
Iron, or Fe, is the only element here. The rest are alloys. I hope this helps!
