Answer:
3 m/s²
Explanation:
Acceleration is calculated as :
a= Δv/ t
where ;
Δv = change in velocity
Δv = 45 - 0 = 45 m/s
t= 15 s
a= 45 /15
a= 3 m/s²
Answer:
the difference in pressure between the inside and outside of the droplets is 538 Pa
Explanation:
given data
temperature = 68 °F
average diameter = 200 µm
to find out
what is the difference in pressure between the inside and outside of the droplets
solution
we know here surface tension of carbon tetra chloride at 68 °F is get from table 1.6 physical properties of liquid that is
σ = 2.69 × N/m
so average radius = = 100 µm = 100 × m
now here we know relation between pressure difference and surface tension
so we can derive difference pressure as
2π×σ×r = Δp×π×r² .....................1
here r is radius and Δp pressure difference and σ surface tension
Δp =
put here value
Δp =
Δp = 538
so the difference in pressure between the inside and outside of the droplets is 538 Pa
Answer:
hello your question is poorly written hence I will give you a general answer
answer :
Hence the opening price = 140 - ( 14 * 3 )
= 140 - 42 = 98.00
Explanation:
To determine the opening price we will subtract or add the percentage Increase or decrease of the Dow Jones from the Final price of the Dow Jones
Lets assume :
Dow Jones Increased by 30 %
Dow Jones final price = 140
Hence the opening price = 140 - ( 14 * 3 )
= 140 - 42 = 98.00
Answer:
Kinetic energy is what makes the object move. Many rides use the transfer of potential energy to kinetic energy to move along the track. When the roller coaster moves downwards, kinetic energy is generated. The maximum kinetic energy generated is when the roller coaster is at the bottom of the track.
