Answer:
, 
Explanation:
From the question we are told that
The initial velocity of the arcade ball is 
The time taken by the ball to enter the basket is 
Generally the x -component of the initial velocity is
=>
Generally the y -component of the initial velocity is
=> 
Generally the distance x is mathematically represented as

=>
=>
Generally from kinematic equation the distance y is mathematically represented as

=>

Answer:
All of teh above except A
Explanation:
Gravitational field strength (GFS) on earth =10 N/kg
Weight = GFS x mass
W = 10 x 7
W = 70N
70N = 15.74 pounds
The answer is; non-metals have a high ionization energy
This means that it would take more energy to dislodge an electron from the valence orbital than it would take to do the same to a metal atom. Therefore it would be easier to share electrons for non-metals while it would be easier to lose an electron for metals to reach a stable electron configuration.
The frequency for a fundamental pipe is given as:
f = v/4L
L is equal to the length of the pipe
Since L = Lo/2 where Lo is the original length of the pipe, the
new frequency would be:
f = (v/4)/(Lo/2)
f = 2 (v/4Lo)
Since v/4Lo = fo, therefore:
f = 2 fo
