Answer:
6m/s
Explanation:
Data obtained from the question include:
Mass = 0.5kg
Momentum = 3 kg.m/s
Velocity =.?
Momentum is simply the product of mass and velocity as shown by the equation below:
Momentum = Mass x Velocity
Velocity = Momentum /mass
Velocity = 3kg.m/s / 0.5kg
Velocity = 6m/s
Therefore, the velocity of the ball is 6m/s
If these are you choices:
(1) Both the solid and the liquid are good conductors.
(2) Both the solid and the liquid are poor conductors.
(3) The solid is a good conductor, and the liquid is a poor conductor.
(4) The solid is a poor conductor, and the liquid is a good conductor.
Then the answer is number 4. This is because ionic compound conducts electricity when it is dissolved in water.
Answer:
there are 9 orbitals in third shell of a atom
formula to calculate is n²
where n - no of shell
orbitals on axial are 6
pH is a symbolic representation of:
and for water we now that:
that means the text give us the information to calculate the concentration of protons and therefore the concentration of ions OH-:
therefore the concentration of OH- can be calculated:
but they are not asking about the concetration of OH- they ask about concentration of Ba(OH)2 and for that we need to know the disolution stechiometry
Whic mean the concentration of Ba(OH)2 is half the concentration of OH-:
