Answer: The final velocity of both man and hokey puck will be 0.056 m/s.
Explanation: We are given 2 objects and are undergoing collision. The final velocity of both the objects is same. To calculate the final velocity, we will use the principle of conservation of momentum.
This principle states that when the objects that are colliding makes up a system, then the total momentum will remain constant if no external force is applied on it.
Sum of Initial momentum of two objects = Sum of Final momentum of the two objects
Mathematically,
...(1)
where,
are the mass, initial velocity and final velocity of the first object.
are the mass, initial velocity and final velocity of the second object.
Here, man and hockey puck are moving together after the collision, so their final velocities will be same.
Putting values in equation 1, we get:
The final velocity of man and hockey puck is 0.056 m/s.
Answer:
SN1 = a stepwise loss of a leaving group to form a carbocation followed by nucleophilic attack
Explanation:
Since 2-methyl-2-butanol is tertiary alcohol, the first step will be loss of leaving group to form a 3° carbocation which is very stable and favours SN1, followed by attack of nucleophile

Answer:
3.1% is the fraction of the sample after 28650 years
Explanation:
The isotope decay follows the equation:
Ln[A] = -kt + Ln[A]₀
<em>Where [A] could be taken as fraction of isotope after time t, k is decay constant and [A]₀ is initial fraction of the isotope = 1</em>
<em />
k could be obtained from Half-Life as follows:
K = Ln 2 / Half-life
K = ln 2 / 5730 years
K = 1.2097x10⁻⁴ years⁻¹
Replacing in isotope decay equation:
Ln[A] = -1.2097x10⁻⁴ years⁻¹*28650 years + Ln[1]
Ln[A] = -3.4657
[A] = 0.0313 =
<h3>3.1% is the fraction of the sample after 28650 years</h3>
