This question is related to density where 16.7 kW power is used.
<h3>What is Density?</h3>Density is defined as mas per unit volume. It is denoted by ρ
We know the density of water is 1000kg/m³.
The given volume is 10m³. we have to find the mass. i.e. 10000 kg.
We know that
Mass = Density x Volume
Mass = 1000kg/ m³ x 10m³ = 10000kg.
Here, We know that work against gravity is mgh.
So, 10000 kg x 10 m/s² x 50m = 5000000J.
But only one fifth of its energy is used.
5000000 / 5 = 1000000
Now we have the work done and time, so lets solve power.
Power=work done /time
1000000/60sec.
Power =16666.67 or 16.7kW

Answer:
t= 25.04 s
Explanation:
Given that
Initial angular speed ,ωi= 26 rad/s
Angular acceleration ,α=0.43 rad/s²
We know that kinetic energy of the wheel given as
I=Mass monent of inertia
ω=Angular speed
If kinetic energy is two time then the final angular speed
We know that
t= 25.04 s
After 25.04 s then kinetic energy will become two times of the initial kinetic energy.
Answer:
F₀ /k .
Explanation:
Force is variable
F=F₀
kinetic energy = work done by force
= ∫ F dx
= ∫F₀ dx
= F₀ / -k
E = F₀ / -k
= -F₀ /(k )
For maximum E , should be minimum ,
is minimum for x = 0
maximum value of E = F₀ /k .
