1. becuase it is so hot that it could tan or be used to keep warm.
Answer:
ans:
tenson(T) = 20 N
acceleration (a) = 2.86 m/s
Explanation:
T + mg = Mg
T = Mg - mg
T = g( M - m )
T = 10× ( 7-5 )
T = 20 N
again;
T = 20
Ma = 20
a = 20 / 7
= 2.86 m/s
Answer:
v₂ = 306.12 m/s
Explanation:
We know that the volume flow rate of the water or any in-compressible liquid remains constant throughout motion. Therefore, from continuity equation, we know that:
A₁v₁ = A₂v₂
where,
A₁ = Area of entrance pipe = πd₁²/4 = π(0.016 m)²/4 = 0.0002 m²
v₁ = entrance velocity = 3 m/s
A₂ = Area of nozzle = πd₂²/4 = π(0.005 m)²/4 = 0.0000196 m²
v₂ = exit velocity = ?
Therefore,
(0.0002 m²)(3 m/s) = (0.0000196 m²)v₂
v₂ = (0.006 m³/s)/(0.0000196 m²)
<u>v₂ = 306.12 m/s</u>
