Answer:

D. Battery

During the oxidation-reduction(redox) reaction, there is always flow of electrons from one point to another. The electrons are then converted to power through the battery which converts chemical energy to electrical energy. If there is zero flow of electrons then there will also be zero power.

Answer:

D. A battery.

Explanation:

A battery cell refers to a single anode and cathode separated by electrolyte used to produce a voltage and current. It is typically an electrolytic cell.

An electrolytic cell is an electrochemical cell that drives a non-spontaneous redox reaction through the application of electrical energy. They are often used to decompose chemical compounds, in a process called electrolysis.

The anode which is positive electrode undergoes oxidation i.e loss of electrons while the cathode(negative) undergoes reduction that is, accept electrons.

Describe You toss a ball to someone one meter away. Then you toss it to someone four meters away. How does your throw change?
krek1111 [17]

We have that the Throw has changed in distance the ball has traveled and the Force applied in trowing the ball and Possibly the time of travel

From the Question we are told that

You toss a ball to someone one meter away

You toss it to someone four meters away

Generally

When you toss toss a ball to someone one meter away and You toss it to someone four meters away the are  things that have changed

  • Force
  • Distance

Therefore

The Throw has changed in distance the ball has traveled and the Force applied in trowing the ball and Possibly the time of travel

. A non-uniform positive line charge of length 2 m is put along the x-axis as shown in the figure, where x​0​=1.5 m. The linear
PilotLPTM [1.2K]

Answer:

E = 7.2*10^{10}N/C

Explanation:

The differential electric field dE due to differential charge dQ at distance x from the origin is

dE = k\dfrac{dQ}{x^2}

but since dQ = \lambda dx = 4x^2dx we have

dE = k\dfrac{4x^2dx}{x^2}

dE = 4k\: dx

integrating this from x_0 to x_0+L we get

$E = \int^{x_0+L}_{x_0} {4k} \, dx $

E = 4k[(x_0+L)-x_0]

E =4kL

putting in k = 9*10^9Nm^2/C^2 and L =2m we get

\boxed{E = 7.2*10^{10}N/C.}

A sound wave of wavelength 0.682 m and velocity 325 m/s is produced for 0.500 s. what is the frequency
Naya [18.7K]
Recall that given the velocity and wavelength, frequency can be computed as

frequency =  \frac{speed}{wavelength}
Substituting the given values, we have
frequency =  \frac{325 m/s}{0.682 m}  \\ frequency = 477 Hz

Answer: 477 Hz
