A 100.0 mL sample of 1.020 M HCl is mixed with a 50.0 mL sample of 2.040 M NaOH in a Styrofoam cup. If both solutions were initi
I am Lyosha [343]

Answer:

t_2 = 33.793

Explanation:

Given data:

0.1 L HCl × 1.020 mol/L = 0.102 mol HCL

0.05 L NaOH × 2.040 mol/L = 0.102 mol NaOH

NaOH + HCl \rightarrow  H_2O + NaCl

0.102 mol HCl /1 mol HCl × 1 mol H2O = 0.102 mol H2O

0.102 mol H2O / 1 mol H2O × 57000 J = 5814 J

V(t ) = V_1+V_2 = 100 + 50 = 150 mL

M(t)=150*1=150 g

we know that heat energy is given as

Q = mc(t_2 - t_1)

where c is specific heat

total energy released is = 57 \times 0.102 = 5.814 kJ

5814 = 150 \times 4.184 \times (t_2 - 24.53)

t_2 = 33.793

An apple is initially sitting on the bottom shelf of a pantry. A hungry physics student picks up the apple to eat it, but change
andre [41]

Answer:

Zero

Explanation:

Work done is given by multiplying force and distance moved. The distance is moved both positive and negative and it's equal distance. Since force used is the same hence work

W=F*d+ (F*-d)=0

Therefore, total work done is zero

Two parallel-plate capacitors have the same plate area, but the plate gap in capacitor 1 is twice as big as capacitor 2. If capa
-BARSIC- [3]

Answer:

Capacitance of the second capacitor = 2C

Explanation:

\texttt{Capacitance, C}=\frac{\varepsilon_0A}{d}

Where A is the area, d is the gap between plates and ε₀ is the dielectric constant.

Let C₁ be the capacitance of first capacitor with area A₁ and gap between plates d₁.

We have    

              \texttt{Capacitance, C}_1=\frac{\varepsilon_0A_1}{d_1}=C

Similarly for capacitor 2

               \texttt{Capacitance, C}_2=\frac{\varepsilon_0A_2}{d_2}=\frac{\varepsilon_0A_1}{\frac{d_1}{2}}=2\times \frac{\varepsilon_0A_1}{d_1}=2C

Capacitance of the second capacitor = 2C

A carbon fiber car bumper is hit by another car with the stress of 106,483 Pa. If carbon fiber has a Young's modulus of 228 x 10
hoa [83]

Answer:

Stress = 4.67 * 10^-7 N/m²

Explanation:

Young's modulus of the material = Stress/Strain

Given

Young's modulus  = 228 x 10^9 Pa

Stress =  106,483 Pa

Required

Strain

From the formula;

Strain = Stress/Young modulus

Strain =  106,483 /228 x 10^9

Stress = 4.67 * 10^-7 N/m²
