Answer:

Correct answer: vₓ = 30V , i₀ = 5A

Explanation:

You first calculate the equivalent resistance of the parallel connection of two resistances of 12 and 6 ohms.

1/ Re₁ = 1/12 + 1/6 = (12 + 6) / (12 · 6) => 1/Re₁ = 18/72 => 1/Re₁ = 1/4 =>

Re₁ = 4Ω

then you calculate the equivalent resistance of a series connection of two resistances of 8 and Re₁ = 4Ω

Re₂ = Re₁ + 8 = 4 + 8 = 12Ω

then you calculate the electric current according to Oh's law

i₀ = vc / Re₂ = 60 / 12 = 5A

at the end you calculate the voltage drop vₓ on the resistor of 6Ω

vₓ = i₀ · 6Ω = 5A · 6Ω = 30V

. Two identical blocks, each of mass M, are connected by a massless string over a pulley of radius R and moment of inertia I. Th

Dima020 [189]

The angular acceleration of a pulley is described under the equation,

$\theta = (0.5) \alpha t^2$

So things clearing,

$\alpha = \frac{ 2\theta}{t^2}$

b) For point B it is necessary to make a sum of Forces,

$\sum F=0$

In this way,

$Mg - T_1 = Ma$

$T_1 = Mg - Ma$ (1)

For block 2, we have the following relationship,

$T_2 = Ma$ (2)

So,

$T_1 - T_2 = I \frac{a}{R}$ (3)

Substituting (1) and (2) in (3)

$Mg - Ma - Ma = I \frac{a}{R}$

So,

$a = \frac{2\theta R}{t^2}$

<em>**Note that</em> $\alpha R = a$

c) For this point we need to use (1)

$T1 = Mg - Ma = Mg - \frac{M^2\theta R}{t^2}$

using (2)

$RT_2=RT_1-I\alpha$

$T_2= \frac{RM(g-\frac{2\theta R}{t^2})-I\frac{2\theta}{t^2}}{R}$

$T_2=\frac{RMgt^2-2R^2M\theta-2t\theta}{Rt^2}$

The speed of light ________ when light goes through glass.

Gala2k [10]

What happens when the light hits the glass depends on what it was in before it hit the glass.

WHILE it's in the glass, the speed of light doesn't change.

What is the mass of a liquid having a density of 1.50 g/ml and a volume of 3.5 liters?

PIT_PIT [208]

We know the formula for density = Mass/ volume

So Mass, M = Volume * Density

Volume = 3.5 L= 0.0035 $m^3$

Density = 1.50 g/ml = 1500 $kg/m^3$

Mass, M = 0.0035*1500 = 5.25 kg

So mass of liquid having density 1.50 g/ml and volume 3.5 liters is 5.25 kg.
