Planck's constant. A physical constant adopted in 2011 by the CGPM.
Answer:
The correct answer is dissolving and the end product is a solution.
Explanation:
Solubility is an property of a substance to get dissolved into another. When a substance, termed as solute, dissolves in another substance, termed as solvent, we get a solution.
Larger molecules of the solute breaks because of weak covalent bonds between their molecules and pairs up with the smaller molecules of the solvent and thus dissolves in it. Not all elements can serve solutes or solvents as some have strong forces that bind them together. For example sugar is a solute in water but oil is not soluble in water.
The distance for both Parts A and B are given in the question.
A balloon drifts 140m toward the west in 45s.
The wind suddenly changes and the balloon flies 90m toward the east in the next 25s.
To find the total distance, we can just add.
140 + 90 = 230m
Best of Luck!
Answer:
The Dimension of mass is [F T v⁻¹] and Dimension of energy is [F T v]
Explanation:
(i) We know that,
Force = mass × acceleration
= mass × velocity/time
⇒ mass = force × time ÷ velocity
or. [mass] = [force] [time] ÷ [velocity]
= [F] [T] ÷ [v]
∴ [mass] = [F T v⁻¹]
(ii) Dimensions of energy are same as the dimensions of kinetic energy
∴ Energy = [ ½mv²] = [m] [v]²
= [F T v⁻¹] [v]²
Energy = [F T v]
Thus, The Dimension of mass is <u>[F T v⁻¹]</u> and Dimension of energy is <u>[F T v]</u>

By definition we have that momentum is the product of the mass of the object by the velocity of the object. In other words:
p = m * v
Both objects have the same speed because they reach the ground at the same time.
However, object a is heavier than object b. The weight of the objects is:
a = 2m
b = m
Therefore the momentum of a and b is
pa = 2mv
pb = mv
Object a has the greatest momentum
Answer
pa> pb
2mv> mv
