Explanation:
Given that,
Position of the particle at t = 0,
Velocity of the particle at t = 0
Acceleration of the particle,
Solution,
(a) Let v is the velocity at t = 10 s. Using the equation of kinematics as :
(b) Let y' is the position at t = 1 s. Again using second equation of kinematics as :
(c) Magnitude of y',
|y'| = 21.69 meters
Direction of the y',
Hence, this is the required solution.
Explanation:
We start by using the conservation law of energy:
or
Simplifying the above equation, we get
We can rewrite this as
Note that the expression inside the parenthesis is simply the acceleration due to gravity so we can write
where is the launch velocity.
(a)
Electronic configuration is given as follows:
Since, this is the electronic configuration of ion with+3 that means 3 electrons are removed. On adding the 3 electrons, the electronic configuration of neutral atom can be obtained.
Thus, electronic configuration of neutral atom is .
The atomic number of Kr is 36, thus, total number of electrons become 36+6=42.
This corresponds to element: molybdenum. Thus, the tripositive atom will be .
(b) The given electronic configuration is .
The atomic number of Kr is 36, thus, total number of electrons become 36+4=40.
This corresponds to element zirconium, represented by symbol Zr.
