Answer:
the active region is bound by cutoff region and saturation or power dissipation region.
Explanation:
Answer:
Electric current, I = 4.08 A
Explanation:
We have,
Power of vacuum cleaner is 500 W
Resistance of vacuum cleaner is 30 ohms
It is required to find the current flowing through the vacuum cleaner. It can be calculated using the definition of power delivered. Its formula is given by :

I is electric current

So, the electric current flowing through the vacuum cleaner is 4.08 A.
Answer:
Shear resistance of a inclined stirrup is given by
Vᵇ = Asb(0.95*Fy)(cos α - sin α*cotβ) ((d-d')/sᵇ)
Explanation:
The shear resistance is checked in accordance with BS8110: Part 1, section 3.5.5. Shear resistance of a inclined stirrup is given by
Vᵇ = Asb(0.95*Fy)(cos α - sin α*cotβ) ((d-d')/sᵇ)
where,
Vᵇ=design shear resistance of inclined bars
Asb=cros-sectional area of the inclined bars
Fy=characteristics strength of the stirrups
α=angle between the inclined bars and the axis of the beam
β=angle between the compression strut of inclined bars and the axis of the beam
sᵇ=spacing of the inclined bars
d= effective depth and d'=effective depth minus cover to reinforcement
The shear stress is given by
v=V/bd
where V is the shear force due to ultimate loads. If v is shear stress
Answer:
The magnitude of the acceleration ae of the earth due to the gravitational pull of the moon is
Explanation:
By Newton's gravitational law, the magnitude of the gravitational force between two objects is:
(1)
With G the gravitational constant, M the mass of earth, m the mass of the moon and r the distance between the moon and the earth, a quick search on physics books or internet websites give us the values:




Using those values on (1)


Now, by Newton's second Law we can find the acceleration of earth ae due moon's pull:
