In the combo circuit diagrammed, R1 = 19.2 Ω, R2 = 20.7 Ω, and R3 = 25.8 Ω. Find the equivalent resistance of the circuit.

Answers

Answer:

Equivalent resistance: 13.589 Ω

Explanation:

R series = R1 + R2 + R3 ...

[tex]\frac{1}{R_{eq} } = \frac{1}{R1} +\frac{1}{R2} +\frac{1}{R3} ...[/tex]

Find the equivalent resistance of the right branch of the circuit:

[tex]R_{eq} = R_{2} +R_{3} \\R_{eq} = 20.7 + 25.8 = 46.5 ohms[/tex]

[tex]\frac{1}{R_{eq} } = \frac{1}{19.2} +\frac{1}{46.5}\\\\\frac{1}{R_{eq} } = 0.0735887097\\\\R_{eq} = 13.5890411[/tex]

300cm3 of O₂ will be collected over water at a temperature of 25°c and 1atm (101325 NM-2) What will be the volume of dry oxygen at S.T.P? (water pressure at 25c is 16630M²)

Answers

The volume of the gas is calculated as 1827.87cm^3

Data;

Initial volume (v1) = 300cm^3Initial Pressure (p1) = 1atm = 101325 NM^-2Final Volume = ?Final Pressure (P2) = 16630NM^-2

Boyle's Law

To find the final volume of oxygen, we have to use Boyle's law which states that the volume of a gas is inversely proportional to the pressure of the gas provided that temperature remains constant.

v ∝ 1/p

[tex]v = \frac{k}{p} \\k = pv\\p_1 v_1 = p_2 v_2[/tex]

Let's substitute the values into the equation and solve.

[tex]p_1v_1 = p_2v_2\\101325*300 = 16630 * v_2\\30397500 = 16630v_2\\v_2 = \frac{30397500}{16630} \\v_2 = 1827.87cm^3[/tex]

The volume of the gas is calculated as 1827.87cm^3

the bottom of the loop. What is the acceleration the bucket will experience at the top of the loop?

Answers

Answer:

Let T + m g = m v^2 / R      

At the top of the loop T can be zero and the force of gravity provides the necessary centripetal force

A. Jane and Matt look like their mother.


B. Only a father can pass on the color of eyes.


C. Hair type is not passed down from parent to child.


D. Jan and Matt inherited eye color from their mother.

Answers

Traits are the expression of alleles combination in a genotype, and depend on the inherited alleles and the inheritance pattern. Option D. Jane can say that she and Matt inherited eye color from their mother.  

How are traits inherited?

Traits are the expression of the allelic combination in a genotype. The expressed phenotype will depend on the alleles inherited from each parent and the inheritance pattern.

According to the segregation principle, alleles separate during gamete formation. And during fertilization, two gametes from different parents merge to produce a zygote.

Each gamete carries one of the parental alleles. During fertilization occurs a combination of alleles that will express a phenotype.

Traits inheritance do not depend on each other, they are inherited by separate.

In the exposed example, eye color and hair type expression depend on the combination of the alleles in each genotype. And each trait is independently inherited from the other one.

A lever is used to lift a heavy weight. The length of the input arm of the lever is 3 m, the length of output arm is 1 m.


What is the mechanical advantage of the lever?

A.) 3

B.) 0.33

C.) 1

Answers

The mechanical advantage of the lever is 3 and the right option is A.) 3.

What is mechanical advantage?

Mechanical advantage can be defined as the ratio of load to effort in a machine.

To calculate the mechanical advantage of the lever, we use the formula below.

Formula

M.A = y/x................ Equation 1

Where:

M.A = mechanical advantage of the levery = distance moved by effort (input arm)x = distance moved by load (output arm)

From the question,

Given:

y = 3 mx = 1 m

Substitute these values into equation 1

M.A = 3/1 M.A = 3.

Hence, The mechanical advantage of the lever is 3 and the right option is A.) 3.

A train has a final velocity of 110 km/h. It accelerated for 36 s at 0.50 m/s2 . What was its initial velocity

Answers

The initial velocity of the train  is 12.56 m/s.

Initial velocity

The initial velocity of the train can be determined by using the first kinematic equation as shown below;

v = u + at

u = v - at

where;

v is the final velocity = 110 km/h = 30.56 m/su is the initial velocity

u = 30.56 - (36 x 0.5)

u = 12.56 m/s

Thus, the initial velocity of the train  is 12.56 m/s.

What is the power output?

Can someone explain me, please!

Answers

Answer:

  2.38 mW

Explanation:

Power is work per unit time. Work is the product of force and distance. That means ...

  [tex]\text{power}=\dfrac{\text{force}\times\text{distance}}{\text{time}}=\text{force}\times\dfrac{\text{distance}}{\text{time}}\\\\\text{power}=\text{force}\times\text{velocity}[/tex]

Using the given values of force and velocity, the tadpole's power output is ...

  P = (0.028 N)(0.085 m/s) = 0.00238 W = 2.38 mW

The tadpole's power output is about 2.38 mW.

What percentage of the initial potential energy has been converted into heat instead of
kinetic energy?

Answers

The percentage of the initial potential energy that has been converted into heat is 18.07%.

What is potential energy?

Potential energy can be defined as the energy of a body due to its position in the gravitational field.

To calculate the percentage of the initial potential energy that has been converted into heat, we use the formula below.

Formula:

H(%) = [(P.E-K.E)/P.E]100............... Equation 1

Where:

H = Energy converted to heatP.E = Potential energyK.E = Kinetic energy.

But,

P.E = mgh........... Equation 2

From the diagram,

m = mass = 0.5 kgh = 7 cm = 0.07 mg = 9.8 m/s²

Substitute these values above into equation 2

P.E = (0.5×9.8×0.07) P.E = 0.343 J

Also From the diagram,

K.E = 0.281 J.

Substitute these values into equation 1

H(%) = [(0.343-0.281)/0.343]100H(%) = 18.07%.

Hence, the percentage of the initial potential energy that has been converted into heat is 18.07%.
