Answer:
mparing this value with the weight of the vehicle we see W₂> 1.6 10⁴ N
therefore the woman can lift the car
Explanation:
For this exercise on Pascal's principle, we use that the pressure in every incompressible liquid is the same
P₁ = P₂
the press is defined by
P = F / A
for the woman's side
the area of a circle is
A = π D₁² / 4
P₁ = W (4 /π d₁²)
for the car side
A₂ =π d₂²
P₂ = W₂ (4 /π d₂²)
we substitute in the first equation
W (4 /π d₁²) = W₂ 4 /π d₂²)
W / d₁² = W₂ / D₂²
W₂ = (d₂ / d₁)² W
the weight of the woman is
W = mg
we calculate
W₂ = (24/3)₂ 50 9.8
W₂ = 3,136 10⁴ N
when comparing this value with the weight of the vehicle we see
W₂> 1.6 10⁴ N
therefore the woman can lift the car
I think it is first but don’t take my word for it
Answer:
Tբ = (C₁T₁ + C₂T₂)/(C₁ + C₂) = (C₁T₁)/(C₁ + C₂) + (C₂T₂)/(C₁ + C₂)
Explanation:
Let's Assume that T₁ > T₂, this means that, T₁ > Tբ > T₂
The zeroth law of thermodynamics explains that two bodies in thermal equilibrium will eventually end up with the same final body temperature.
Heat lost by body 1 = Heat gained by body 2
C₁ (T₁ - Tբ) = C₂ (Tբ - T₂)
C₁T₁ - C₁Tբ = C₂Tբ - C₂T₂
C₁Tբ + C₂Tբ = C₁T₁ + C₂T₂
Tբ(C₁ + C₂) = C₁T₁ + C₂T₂
Tբ = (C₁T₁ + C₂T₂)/(C₁ + C₂)
Tբ = (C₁T₁)/(C₁ + C₂) + (C₂T₂)/(C₁ + C₂)
Answer:
2.75 m/s^2
Explanation:
The airplane's acceleration on the runway was 2.75 m/s^2
We can find the acceleration by using the equation: a = (v-u)/t
where a is acceleration, v is final velocity, u is initial velocity, and t is time.
In this case, v is 71 m/s, u is 0 m/s, and t is 26.1 s Therefore: a = (71-0)/26.1
a = 2.75 m/s^2
Answer: Food Chain and Food Web. Food chain is a linear sequence of organisms which starts from producer organisms and ends with decomposer species. Food web is a connection of multiple food chains.
