In salty water ions are produced by the salt

here salt is NaCl

so it will break in Na⁺ and Cl⁻

They carry the current

Na⁺ moves towards cathode and Cl⁻ moves towards anode

So current is carrying by ions which are Na⁺ and Cl⁻

You walk 20 m north then 30 m west for a total timer four minutes what is the magnitude of your average velocity in (m/s)
Shalnov [3]

Answer:

The average velocity is 0.15 m/s

Explanation:

Use the definition of average velocity as the distance traveled divided the time it took.

Since the movement was on the plane from the origin (0, 0) to the point (-30, 20) corresponding to 30 m west and 20 m north, we calculate the distance using the distance between two points on the plane:

distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} = \sqrt{(-30)^2+20^2} =\sqrt{1300} \approx 36.06\,\,m

Then the magnitude of the average velocity can be estimated via the quotient between distance divided time, but since the units required are meters per second, we first convert the four minute time into seconds: 4 * 60 = 240 seconds.

Then the average velocity becomes:

v_{ave}=\frac{distance}{time} =\frac{36.06}{240} =0.15\,\,m/s

Is a battery a resistor
-Dominant- [34]
A battery is a real-life voltage source. A battery can be thought of as a perfect voltage source with a small resistor (called internal resistance) in series. ... The terminal voltage equals the emf minus the voltage drop across the internal resistance (current of the external circuit times the internal resistance.)

A 40.0 -kg box initially at rest is pushed 5.00 m along a rough, horizontal floor with a constant applied horizontal force of 13
Irina18 [472]

The work done by the gravitational force = 0

Given the mass of the box = 40 kg

The box is initially at rest.

Distance moved by the applied force = 5m

Force applied = 130 N

Co-efficient of friction between the box and floor = 0.3

The box is moved only in the horizontal direction by the applied force.

Gravitational force is applied in a direction perpendicular to the applied force. hence it doesn't do any work on the box.

Therefore, the work done by the gravitational force is zero.

A hockey player applies an average force of 80.0 N to a
denpristay [2]

Answer:

Impulse =  8.0Ns

Explanation:

Given

Force = 80.0N

Mass = 0.25kg

Time = 0.10s

Required

Determine the impulse

The impulse is calculated as follows:

Impulse =  Force * Time

Substitute values for Force and Time

Impulse =  80.0N * 0.10s

Impulse =  8.0Ns

<em>Hence, the impulse experienced is 8.0Ns</em>
