It would be a) 2 electrons
Answer:
7.5 m
Explanation:
k = Spring constant = 180 N/m
x = Displacement of spring = 14 cm
m = Mass of projectile = 0.024 kg
a = g = Acceleration due to gravity = 
s = Displacement of projectile
v = Final velocity = 0
u = Initial velocity
The potential energy of the spring will be equal to the kinetic energy of the object


The maximum height reached above the initial position is 7.5 m
Answer:
The Executive Branch and if there is a different answer I would say The Congress and the President
When the ball on a spring is replaced by a smaller ball with half the mass : The period decrease by 29%
<h3>Calculate the Period </h3>
We will apply the formula below to calculate period
T =
where :
T₁ / T₂ =
where m₂ = m₁ / 2
Therefore :
T₂ =
= 0.71 T
Hence we can conclude that the period will decrease by 29% ( i.e 100 - 71 ).
