At the peak of its flight ALL the energy given to the rocket is potential energy (its velocity is zero) and that is calculated as mgh So Energy given to rocket = mgh Energy expended by engine = F x D (D= height where engine stops) Energy 'lost' to drag is the difference between the two values. please if this helped mark it as the brainiest answer.
A soccer ball would keep moving forever without physics, because without force to act upon the soccer ball, it could, or will not be able to stop the acceleration. And force is a factor in physics.
Explanation:
Given that,
Diameter = 10 cm
Distance = 2 m
Speed 
Speed 
Pressure in main pipe 
(I). We need to calculate the diameter
Using equation of continuity
(II). We need to calculate the pressure the gauge pressure
Using Bernoulli equation
(III). If it is possible to carry water to a faucet 17 m above ground,
Using Bernoulli equation
Here, 
Put the value in the equation
Hence, This is required solution.
<span>You could easily define it this way. This would be valid. But for most of history it was unclear when a baby was conceived, so it would be silly for someone to say their baby was 9 months old when it was actually born at only 8.5 months. Days of conception similarly would not be a good substitute for birthdays because no one would know them. Then in general it was much easier to mark someone's age as when they came into the world as an independent being, and this tradition is far too entrenched (and simple and easy to handle and universal for people in poor countries etc) to think we would at all gain from now finding exactly the date of conception and counting age from that point.</span>
Answer:
ΔS = 7.618 J/K
Explanation:
The entropy change associated to an isothermal process is:
ΔS = 
We can calculate Q (heat) how:
Q = nRTln(
)
Where Vf = 2.5v
Vi = v
R = 8.314J/mol.k (Constant of ideal gases)
n: Number of moles = 1 mol
Then
Q = nRTln(2.5)
ΔS = 
ΔS = (1)(8.314)ln(2.5)
ΔS = 7.618 J/K
