Answer:
Radial force component of force = 37.68 N
Explanation:
By Newton's 2 nd law of motion,
F = ma
F = 3.0 N, m = 0.5 Kg, a (Linear Acceleration ) = ?
3 = 0.5 a
a = 6
Now, a = 6 , r = 2.5 m ,α(angular acceleration ) = ?
a = r α
6= 2.5 α
hence α = 2.4 rad/
we know that,
Radial force component of force =
since m =0.5 kg, r =2.5 m w =5.49 rad/sec
Radial force component of force = = 37.68 N
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
Refractive Index is a ratio of two similar physical quantity which is dimension less
refractive index = sin I / sin r
therefore it doesn't have a unit.
Answer:
no poop comes out from your but
Explanation:
Explanation:
Momentum before = momentum after
m₁ u₁ + m₂ u₂ = m₁ v₁ + m₂ v₂
(50.0 kg) (0 m/s) + (12.0 kg) (0 m/s) = (50.0 kg) (2.0 m/s) + (12.0 kg) v
v = -8.33 m/s
