Answer:
the time between successive meridian transits of the sum at a particular place
The subatomic particles found in the area surrounding the nucleus of an atom are called electrons.
Answer:
physical quantity
Explanation:
All quantity in term of which laws of physics are described and can be measured is called physical quantity
Since the greatest number in the given electron configuration of the atom is 4, it means that the element is found in the fourth energy level. The number of electrons found in the valence shell is 2+10+6 = 18. From this answer and using the periodic table, we can see that the atom is that of Krypton (Kr).
consider the motion in vertical direction
v = initial velocity in the vertical direction = ?
v' = final velocity in the vertical direction at the highest point = 0 m/s
a = acceleration due to gravity = - 9.8 m/s²
h = maximum height = 12.2 m
Using the kinematics equation
v'² = v² + 2 a h
0² = v² + 2 (- 9.8) (12.2)
v = 15.5 m/s
let assume that velocity of launch be v₀
θ = angle of launch = 13
vertical component of the velocity of launch is given as
v = v₀ Sinθ
15.5 = v₀ Sin13
v₀ = 69 m/s
