Answer:
19.642 cm
Explanation:
f₁ = Focal length of first lens = 11 cm
f₂ = Focal length of second lens = -25 cm
Combined focal length formula
Combined focal length is 19.642 cm

for an approximate result, multiply the energy value by 6.242e+18
Answer:
Explanation:
Given ; P1 = 100 kPa, T1 = 30°C, T2 = 90°C, P2 = 200 kPa, V1 = 350 m/s
From energy conservation at inlet and outlet
h1 + (1/2)v1² = h2 + (1/2)v2²
CpT1 + (1/2)v1² = CpT2 + (1/2)v2²
.718(90-30) x 103= 0.5x (350²-v2²)
velocity at the exit of a diffuser ; V2=190.63m/s
Atoms found in nature are either stable or unstable. An atom is stable if the forces among the particles that makeup the nucleus are balanced. An atom is unstable (radioactive) if these forces are unbalanced; if the nucleus has an excess of internal energy. Instability of an atom's nucleus may result from an excess of either neutrons or protons. Ccredits: internet source
Answer:
Average force exerted by the water on the blades is 1024 N
Explanation:
As we know that the force due to water jet is given by
here we know that
so here we will have
Average force exerted by the water on the blades is 1024 N
