The mass that must be added is 0.628 kg
Explanation:
The period of a mass-spring system is given by
where
m is the mass
k is the spring constant
For the initial mass-spring system in the problem, we have
m = 0.500 kg
T = 1.36 s
Solving for k, we find the spring constant:
In the second part, we want the period of the same system to be
T = 2.04 s
Therefore, the mass on the spring in this case must be
Therefore, the mass that must be added is

Answer:14 s
Explanation:
Given
Velocity of ant is 0.1 m/s in a direction 
if it has traveled 1 m perpendicular to the edge of the sidewalk
i.e. from diagram
A is correct according to below calculation.
m₁v₀₁+m₂v₀₂=m₁v₁+m₂v₂
((m₁v₀₁+m₂v₀₂)-m₁v₁)/m₂=v₂
v₂=((.5*12-.75*16)+(.5*21.6))/.75
v₂=6.4 m/s

Explanation:
1. Indeed, many health experts often recommend that when children reach the age of adolescents (between ages 10 and 19) they should eat a variety of foods daily in other to have enough energy and nutrients needed for development.
2. Having regular meals (mornings, afternoon, and evenings) has for long been encouraged by medical professionals in other to provide the body its fuel.
3. Some skin problems have long been associated with too much consumption of sweets and desserts since these products often contain sugars, and excess processed sugar intake is said to increase acne and eczema.
