It is becomes difficult to walk on a slippery road due to low friction. ... We can not fix nail in the wood or wall if there is no friction. ... A horse can not pull a cart unless friction furnishes him a secure Foothold. We can write on a paper or on a board.
Answer:
31.6 m/s
Explanation:
Mass is conserved, so the mass flow at the outlet of the pump equals the mass flow at the nozzle.
m₁ = m₂
ρQ₁ = ρQ₂
Q₁ = Q₂
v₁A₁ = v₂A₂
v₁ πd₁²/4 = v₂ πd₂²/4
v₁ d₁² = v₂ d₂²
Now use Bernoulli equation:
P₁ + ½ ρ v₁² + ρgh₁ = P₂ + ½ ρ v₂² + ρgh₂
Since h₁ = 0 and P₂ = 0:
P₁ + ½ ρ v₁² = ½ ρ v₂² + ρgh₂
Writing v₁ in terms of v₂:
P₁ + ½ ρ (v₂ d₂²/d₁²)² = ½ ρ v₂² + ρgh₂
P₁ + ½ ρ (d₂/d₁)⁴ v₂² = ½ ρ v₂² + ρgh₂
P₁ − ρgh₂ = ½ ρ (1 − (d₂/d₁)⁴) v₂²
Plugging in values:
579,160 Pa − (1000 kg/m³)(9.8 m/s²)(15 m) = ½ (1000 kg/m³) (1 − (1.99 in / 3.28 in)⁴) v₂²
v₂ = 31.6 m/s
Answer:
Stacked - Cell
Explanation:
DRAM is an acronym that means Dynamic Random access memory. It is a type of random access semiconductor memory that stores it's data in a memory cell where a tiny capacitor and a transistor are.
A Trench Capacitor, or otherwise called Deep Trench Capacitor(DTC). They can store only between 4 mb and 256 mb
Stacked Cells occur when individual batteries are stacked together, to achieve a higher voltage and or Power. They can store up to 1 GB of data.
Planar Capacitor, unlike stacked cells and trench capacitors, can only store data of not more than 1 mb. Planar Capacitor happens to be the smallest out of the three.
From the above explanation, it is obvious that Stacked Cells is the answer.
Answer:
B. There is more room for the air to spread out
