Solve the
potential energy at point B
PE = mgh
Where m is
the mass
G is the
acceleration due to gravity 9.8 m/s2
H is the height
PE = ( 1.5
kg) ( 9.8 m/s2) (0.5 m)
PE = 7.35 J
Solve the
velocity using the
KE = 0.5mv^2
Where ke is
the kinetic energy
M is the
mass
V is the
velocity
Since all
energy is converted to KE
So KE = PE
7.35 = 0.53(1.5)
v^2
V = 3.13 m/s

Answer:
The sneeze centre sends signals to the parts of your body that need to work together to help you sneeze. Your chest muscles, diaphragm, abdominals, vocal cords and the muscles in the back of your throat all work together to help you expel the irritant. Muscular, immune, nervous, respiratory.
Explanation:
To ensure that the drinking
water for the public is safe, the Safe Drinking Water Act (SDWA) is
promulgated. The EPA is required to set standards for drinking water quality
