The current flowing through each wire is the experiment's independent variable because it is the one that the experimenter is actively manipulating and controlling.

The resistance is influenced by the wire's thickness, so the thicker the wire, the lower the resistance. Because less water can flow through a narrower pipe in a given length, there is more resistance in a narrower pipe.

Due to the alloy composition of nichrome wire, its resistance is quite high. Because of this, it generates a lot of heat when current flows through it, making it extremely hot to the touch.

The electric field strength at a distance of 1.20 m on the x-axis is -1.5 × 10⁴ N/C.

To find the electric field strength at a distance 1.20 m on the x-axis, we can use Coulomb's law:

\($$F=k\frac{q_1q_2}{r^2}$$\)

where F is the force between two charges, q1 and q2 are the magnitudes of the charges, r is the distance between the charges, and k is the Coulomb constant.For a single point charge q located at the origin of the x-axis, the electric field E at a distance r is given by:

\($$E=\frac{kq}{r^2}$$\)  where k is the Coulomb constant.

So, let's calculate the electric field due to each charge separately and then add them up:

For the +2.0 C charge at x = 0, the electric field at a distance of 1.20 m is:\($$E_1=\frac{kq_1}{r^2}=\frac{(9\times10^9)(2.0)}{(1.2)^2}N/C$$\)

For the -3.0 C charge at x = 0.40 m, the electric field at a distance of 1.20 m is:

\($$E_2=\frac{kq_2}{r^2}\)

\(=\frac{(9\times10^9)(-3.0)}{(1.20-0.40)^2}N/C$$\)

The negative sign indicates that the direction of the electric field is opposite to that of the positive charge at x = 0.

To find the net electric field, we add the two electric fields\(:$$E_{net}=E_1+E_2$$\)

Substituting the values of E1 and E2:

\($$E_{net}=\frac{(9\times10^9)(2.0)}{(1.2)^2}-\frac{(9\times10^9)(3.0)}{(0.8)^2}N/C$$E\)

net comes out to be -1.5×10⁴ N/C.

Therefore, the electric field strength at a distance of 1.20 m on the x-axis is -1.5 × 10⁴ N/C.

The rock takes 8.16s to return to its release point. Given that the elastic band provides a speed of 40m/s to the rock in 10 cm stretch.

Initial speed of the rock, u = 40m/s

Final position of the rock s = 0m taking the release point as reference. The rock takes 8.16s to return to its release point. Given that the elastic band provides a speed of 40m/s to the rock in 10 cm stretch.

Nuclear energy is a useful source of power but has disadvantages. The disadvantage of nuclear energy is it produces dangerous waste.

Initial speed of the rock, u = 40m/s

Final position of the rock s = 0m taking the release point as reference

From the second equation of motion:

solving above we get:

t = 0s or t = 8.16s,  t =0  seconds is neglected since it represents the initial position which is the same as the final position at t = 8.16s

So, the rock takes 8.16 seconds to return to the release point.

Answer:

La velocidad media es 5 \(\frac{km}{h}\), que equivale a 1.389 \(\frac{m}{s}\)

Explanation:

La velocidad es una magnitud física que expresa la relación entre el espacio recorrido por un objeto y el tiempo empleado para ello.

La velocidad media relaciona el cambio de la posición con el tiempo empleado en efectuar dicho cambio. Por lo que se calcula como la distancia recorrida por un objeto dividido por el tiempo transcurrido:

\(velocidad=\frac{distancia}{tiempo}\)

The Mpemba effect is the name given to the assertion that it is quicker to cool water to a given temperature when the initial temperature is higher.

Marie Curie was a polish-french physicist and chemist who conducted pioneering research on radioactivity.

The duration it take by the boat to cross the river is 25 s.

To solve this question, we will first use Pythagorean theorem to find the width of the river.  Pythagorean theorem is given as:
\({a^2} + {b^2} = {c^2}\)

where a and b are the lengths of the legs of the triangle, and c is the length of the hypotenuse, which is the distance the boat travels.
Now, from the information given, we know that the width of the river (a) is 0.20 km = 200 m, the speed of the river (b) is 3.0 m/s and the speed of the boat (c) is 8.0 m/s.
Using Pythagorean theorem:
{a^2} + {b^2} = {c^2}{200^2} + {3^2} = {c^2} 40000 + 9 = {c^2}{c^2} = 40009
Taking the square root of both sides:
c = 200.02 m
Now that we know the length of the hypotenuse, we can find how long it takes the boat to cross the river. Time (t) is given by the formula:
\(t = d/v\) where d is the distance traveled and v is the velocity (speed).
For the boat, the distance traveled is the length of the hypotenuse, which is c = 200.02 m. Therefore:
\(t = d/v\)

\(t = 200.02 m / 8.0 m/s\)

t = 25.0025 s ≈ 25 s

Therefore, the answer is (c) 25 s.

Answer:

When several resistors are connected in series, the total resistance equals the sum of the individual resistors. In series combination, the current is same through each resistor.

1)   V=  60 volt

Total resistance R = R₁ + R₂

                              = 20 + 10

                              = 30 Ω

2) Ohms law states that,

           \(\sf I =\dfrac{V}{R}\\\\\\I = \dfrac{60}{30}\\\\I = 2 \ A\)

3) Voltage around 10 Ω resistor,

          V₂ = I R₂

             = 2 * 10

              = 20 volt

___________________________________________________

4) Total current = 1 A

5) Total voltage = 8 volt

6) Voltage around R₁ is V₁

              R₁ = 2 Ω  ; I = 1 A

              V₁ = IR₁

                   = 1 * 2

                   = 2 volt

7) Resistance 2:

        Total resistance = R

        Total voltage = V = 8 volt

        Total current = I = 1 A

                  \(\sf R = \dfrac{V}{I}\\\\\\ R = \dfrac{8}{1}\\\\\)

                  R = 8 Ω

               R₁ + R₂ = 8 Ω

                2 + R₂ = 8

                      R₂  = 8 - 2

                      R₂ = 6 Ω

8)Voltage around R₂:

                  \(\sf V_2 = IR_2\\\\V_2 = 1*6\\\\\)

                  V₂ = 6 volt

9) Total R = 8 Ω

_________________________________________________

10) Total V = 12 volt

11)  Total R = 8 + 8

                 = 16 Ω

12) Total current I,

                \(\sf I = \dfrac{V}{R}\\\\I = \dfrac{12}{16}\\\\I = 0.75 \ A\)

13) Voltage at each resistor:

           V₁ = I*R₁

               = 0.75 * 8

               = 6 volt

         V₂ = I*R₂

              = 0.75 * 8

             = 6 volt

_______________________________________________________

     14) Total R =   40 + 20

                       = 60 Ω  

15) To find V₁, first find total voltage.

           I = 2 A ;  R = 60 Ω  

           V = IR    

              = 2 * 60

               = 120 V

        V₁ + V₂  =V

        V₁ + 80 = 120

                V₁ = 120 - 80

                 V₁ = 40 volt

Given that

speed u=4*10^6 m/s

electric field E=4*10^3 N/c

distance b/w the plates d=2 cm

basing on the concept of the electrostatices

now we find the acceleration b/w the plates  to find the horizontal distance traveled by the electron when it hits the plate.

acceleration a=qE/m=\(1.6*10^{-19}*4*10^3/9.1*10^{-31} =0.7*10^{15}\)=\(7*10^{14}\) m/s

now we find the horizontal distance traveled by electrons hit the plates

horizontal distance

\(X=u[2y/a]^{1/2}\)

=\(4*10^6[2*2*10^{-2}/7*10^{14}]^{1/2}\)

=\(3*10^{-2}\)= 3 cm

The electron would need to attain a speed of at least \(2.813*10^7 m/s\)

Data;

The distance of the electron from the center of the sphere  = (1 + 1)mm = 2mm.

\(2mm = 2.0*10^-3m\)

Using centrifugal force of attraction and coulomb's law, we can determine the speed which the electron needs.

\(\frac{mV^2}{R}=\frac{Kq_1q_2}{r^2}\\ K = \frac{1}{4\pi \epsilon } \\ V^2 = \frac{q_1R\\}{4\pi \epsilon \ m r} \\v = \sqrt{\frac{1.0*10^-^9*1.602*10^-^1^9}{4\pi \epsilon *9.1*10^-^3^1*2.0*10^_3} } \\\)
