Find the equivalent resistance of this circuit.​

[tex]R_{eq(23)} = \left(\dfrac 1{R_2} + \dfrac{1}{R_3}\right)^{-1}\\\\\\~~~~~~~~~= \left( \dfrac 1{200} + \dfrac 1{300} \right)^{-1}\\\\~~~~~~~~~=\left( \dfrac{5}{600} \right)^{-1}\\\\\\~~~~~~~~~=\dfrac{600}5\\\\\\~~~~~~~~~= 120~ \Omega[/tex]

Step-by-step explanation :

Here we have to calculate the equivalent resistance of the parallel combination between R2 and R3.

As we know that,

>> 1/Rp = (1/200) + (1/300)

>> 1/Rp = (300 + 200 / 600)

>> 1/Rp = 500 / 600

>> 1/Rp = 5 / 6

>> Rp = 6 / 5

>> Rp = 1.2Ω

Therefore,

In earlier washing machine, the electrical energy is converted in rotational kinetic energy. Now a days, in washing machine, the electrical energy is converted in kinetic energy then the mechanical energy is converted into heat energy. In modern machines, we can wash and dry the clothes.

The currrent flowing the circuit with the given voltage and resistance is 0.25 Ampere.

Option A) 0.25A is the correct answer.

Ohm’s law states that "the potential difference between two points is directly proportional to the current flowing through the resistance.

It is expressed as;

V = I × R

Where V is the voltage or potential difference, potential difference, I is the current and R is the resistance.

Given that;

We substitute our given values into the expression above.

V = I × R

9.0V = I × 36.0Ω

I = 9.0V / 36.0Ω

I = 0.25A

Therefore, the currrent flowing the circuit with the given voltage and resistance is 0.25 Ampere.

Option A) 0.25A is the correct answer.

Scientist in the laboratory create uniform electric field.

PART A: The electric field in rocket frame is  (0,0,  6.0 × 10 ⁵).

PART B: The magnetic field in the rocket frame is  7.3 × 10⁻⁶ j∧  .

The electric field whose strength is not changing with respect to time is called uniform magnetic field.

The electric field is 6.0 × 10 ⁵ k^v/m and the magnetic field is zero.

E' = E + (V×B)

    = 6.0 × 10 ⁵ + (1.1 × 10⁶ × 0)

E' = 6.0 × 10 ⁵ k∧

(Ex , Ey, Ez) = (0,0,  6.0 × 10 ⁵)

The new magnetic field is represented as

B' = B - 1 /c²(v × E)

A passenger experiences centripetal acceleration when there is circular motion around a center. The centripetal acceleration is 3 m/s².

The centripetal acceleration is the acceleration acting when a body is moving on a circular path. It is acted towards the center of the path. Centripetal acceleration is the product of the square of angular speed and radius of path.

a =ω²r

Given the radius of path r is 12 m and angular speed ω is 0.50 rad/s².

The resulting centripetal acceleration is

a = (0.50)²×12

a = 3 m/s²

Thus, the centripetal acceleration is 3 m/s².

The moment of inertia of the tetrahedron will be 435.75,Moment of inertia is found by the application of integration.

The sum of the products of the mass of each particle in the body with the square of its distance from the axis of rotation expresses a body's tendency to resist angular acceleration.

The moment of inertia  of a tetrahedron of constant density is found as;

[tex]\rm I_Z = \int\limits^a_b {dz} \, dv \\\\ dv=dxdy\\\\ I_Z = \int_0^9 \int_0^{8-\frac{8x}{9}} \int_0^{5-\frac{5x}{9} -\frac{5x}{8} }(x^2+y^2)dzdy[/tex]

After applying the limit, we get the answer is;

Hubbles' law is applicated on galaxies. The galaxy which is 1000 Mly distant from us has the speed 20000 km/s.

Hubble's law is defined as the galaxies are moving away from Earth at speeds proportional to their distance.

Hubble's law is written as

v = H₀d

Here v is the recession velocity of a galaxy located a distance d away from us, and H₀ is Hubble's constant.

Suppose H₀ = 20 km/s/Mly.

1 parsec = 3.08 ₓ 10¹⁶ m

1 M parsec = 3.08 ₓ 10²² m

The speed v of the galaxy is

v = 20 ₓ 1000

v = 20000 km/s

Thus, the galaxy which is 1000 Mly distant from us has the speed 20000 km/s.

k.e = ?

solution

k.e=p.e

so p.e=MGH

p.e=MGH

=3kg*9.8m/S2*12m
