Answer:
Pitch. The sound an article makes changes relying upon how quick it is vibrating. At the point when an item vibrates rapidly, sharp sounds are heard. Low-pitched sounds come from things that vibrate all the more gradually.
Explanation:
Formulas you need for this problem:
F= mass•acceleration
KE= mass•velocity^/2
Acceleration= final velocity-intial velocity/time
time= distance/speed
t= 97.5\10= 9.75 seconds
Acc= 10-20/9.75= -1.03 m/s/s
These are the answers :)
F=650•-1.03= -669.5N
KE= 650•100/2= 32,500J or 32.5KJ
Answer:
Force = 22508.86 N
Explanation:
Given:
Area of the window, A = 2.02 m²
Air pressure inside the house, P₁ = 1.02 atm
External air pressure, P₂ = 0.910 atm
Now, The difference in the pressure, ΔP = P₁ - P₂ = 1.02 - 0.910 = 0.11 atm
or
ΔP = 0.11 atm × (101300 Pa / 1 atm )
ΔP = 11143 Pascals
Now,
the Force is given as:
Force = Pressure × area
on substituting the values, we get
Force = 11143 Pa × 2.02 m²
or
Force = 22508.86 N
