Answer: Option (d) is the correct answer.

Explanation:

In an electric circuit, when we press the switch or button then the circuit becomes complete. Then first of all current starts to flow from the energy source which might be a battery or cell etc.

Then the current reaches to the buzzer and hence, it makes a sound. After that, the current moves towards the battery or cell by completing its path.

Thus, we can conclude that the electric charges move from the energy source through the buzzer and back to the energy source.

The atmosphere has many roles, including:
monitta
There are five layers of the atmosphere and these are; troposphere, stratosphere, mesosphere, thermosphere and exosphere. The first layer, troposphere, is where we are able to do most of our activities. This is where we can see the formation of clouds, the production of rain, hail, snow and other weather phenomenon. Also, this layer is where the greatest amount of air pressure because most of the molecules of air are in this area. Like us, air has also mass and the pressure is brought down by the earth’s gravity causing an increase in weight exerted on you as you descend lower into the atmosphere. So, as you enter into the other layers of atmosphere above the troposphere, the air pressure starts to decrease. <span>Below the atmosphere is the hydrosphere. This is where all liquid forms are located. And since the seawater has a greater mass than air, it has the greatest pressure. </span>

If you push on the wall with a force of 400 N, what is the magnitude of the force at the wall exerts on you?
Inessa05 [86]

Answer:

400 N

Explanation:

Due to action-Reaction, the wall pushes back on the person with a force of equal magnitude and in opposite direction to the force exerted by the person.

So the magnitude must be also 400 N.

An ethernet cable is 3.80 m long and has a mass of 0.210 kg. A transverse pulse is produced by plucking one end of the taut cabl
Tasya [4]

Answer:

T=94.54N

Explanation:

The tension in a cable is given by:

T=\mu v^2(1)

Where \mu is the mass density of the cable and v is the speed of the cable's pulse. These values are defined as:

\mu=\frac{m}{L}(2)\\v=\frac{d}{t}

The pulse makes four trips down and back along the cable, so d=4(2L)

v=\frac{8L}{t}(3)

Replacing (2) and (3) in (1), we calculate the tension in the cable:

T=\frac{m}{L}(\frac{8L}{t})^2\\T=\frac{64mL}{t^2}\\T=\frac{64(0.21kg(3.80m))}{(0.735s)^2}\\T=94.54N
