Answer:
All of them are examples of potential energy.
Explanation:
All of the following are examples of potential energy EXCEPT Imbalance in electrical charges of molecules across a cell membrane. O Both: chemical bond (C-H) in fatty acids AND concentration gradient. O Chemical bond (C-H) in fatty acids. O Concentration gradient. O All of them are examples of potential energy.
Answer:
Explanation:
given wave = 8.5 x 10⁻³ cos ( 172 x - 2730t )
here wave no k = 172
angular frequency ω = 2730
velocity of wave on the string
a )
v = ω / k
= 2730 / 172
= 15.87 m/s
time taken to travel full length
= 1.2 / 15.87
= 75.6 x 10⁻³ s
b )
For velocity of wave on the wire the formula is
T is tension and m is mass per unit length of wire
m = .0121 / ( 9.8 x 1.2 )
= 1.03 x 10⁻³ kg / m
15.87 =
W = .259 N
c ) wavelength λ = 2π / k
= 2 x 3.14 / 172
= .0182 m
no of wave length
n = 1.2 / .0182
= 66 approx .

Answer:
The energy loss due to friction is 9465 J.
Explanation:
The given data :-
Mass of roller (m) = 500 kg.
The speed of roller coaster at height 27 m = 5.6 m/s.
Initial height of roller( h ) = 27 m.
The speed of roller coaster at bottom = 22 m/s.
Initial energy of roller at a height 27 m.
E₁ = K.E + P.E
E₁ = = = 7840 + 132435
E₁ = 140,275 J
The energy of roller at a height 2 m.
E₂ = K.E + P.E
E₂ = = = 121000 + 9810
E₂ = 130,810 J
The energy loss due to friction = E₁ - E₂ = 140,275 - 130,810 = 9465 J.
Answer:
The Graph Shows World Disasters.
Answer Pt.2:
As we all can see the tornado's Have the highest ratings of natural disasters, Hurricane's happen the next most, Landslide's happen less often, Wildfires also happen less often whereas Earthquakes nearly never happen, they are very rare to the world.
