Answer:
A total = 0.04 m²
Explanation:
given data
mass = 75 kg
area = 0.05 m²
pressure = 3 kPa
solution
pressure when human walking on ground
p = .................1
p =
p = 14.715 kPa
and
when walk on snow got extra pressure
P total = p + p (extra) ................2
P total = 14.715 + 3 = 17.715 kPa
and
total pressure is also
p total =
A total =
A total = 0.04 m²
Answer:
Rf=470 ohms R1=10ohms, Schmatic is attached
Explanation:
For non-inverting amplifiers
Gain= 1+(Rf/R1)
480=1+(Rf/R1)
470=Rf/R1
if Rf=470Ω and R1=10Ω
then,
47=47
Answer:
Option A
Explanation:
As per the article "Time Travel Is A Fun Science Fiction Story But Could It Be Real?" the gravitational field is a representation of curving space and time. As the gravity becomes strong, the space-time get more curved and hence the time gets slower.
Hence, option A is correct
Answer:
v₂ = 1.25 m/s
Explanation:
given,
inlet velocity, v₁ = 5 ft/s
inlet Area = A = 10 ft²
outlet velocity, v₂ = ?
outlet Area = 4 A
= 4 x 10 = 40 ft²
Using continuity equation
A₁ v₁ = A₂ v₂
10 v₁ = 40 v₂
v₂ = 1.25 m/s
Hence, the exit velocity of the water through the duct is equal to 1.25 m/s.
