Calculate the magnitude of the electric field at the location of given that the square is 6.05 cm on a side.
Serggg [28]

The term “electric field” refers to the physical field that surrounds electrically charged particles and acts to either attract or repel all other charged particles in the field (also known as an E-field).

It can also refer to the physical field surrounding a system of charged particles. Electric fields are composed of electric charges and time-varying electric currents.

Both electric and magnetic fields are manifestations of the electromagnetic field, one of the four fundamental interactions (sometimes known as forces) of nature.

Electrical technology makes use of electric fields, which are significant in many branches of physics.

For instance, in atomic physics and chemistry, the electric field acts as an attractive force to hold atoms’ atomic nuclei and electrons together. It is also the force that causes atoms to chemically link together to form molecules.

Professional Application: A 30,000-kg freight car is coasting at 0.850 m/s with negligible friction under a hopper that dumps 11
Nataliya [291]

Answer:

0.182 m/s

Explanation:

m1 = 30,000 kg, m2 = 110,000 kg, u1 = 0.85 m/s

let the velocity of loaded freight car is v

Use the conservation of momentum

m1 x u1 + m2 x 0 = (m1 + m2) x v

30,000 x 0.85 = (30,000 + 110,000) x v

v = 0.182 m/s

Convert 3.5 km/hr to m/s
Nastasia [14]

Answer:

0.972222........

Explanation:

1. Convert km/h to m/h by multiplying by 1000

2. Divide by 60 so that you have 58.3333... meters per minute

3. Divide by 60 again so now you have 0.972222... m/s

A 28 kg mass suspends from a light rope 18 m long & is held to one side by the horizontal force, F, as shown below.
frutty [35]

Answer: 215.15 N

Explanation:

If we draw a free body diagram of the mass we will have the following:

\sum{F_{x}}=-Tcos\theta + F=0 (1)

\sum{F_{y}}=Tsin\theta - mg=0 (2)

Where T is the tension force of the rope, m=28 kg the mass, g=9.8 m/s^{2} the acceleration due gravity and mg is the weight.

On the other hand, we can calculate \theta as follows:

cos\theta=\frac{s}{l}

\theta=cos^{-1}(\frac{s}{l})

Where s=11.1 m and l=18 m

\theta=cos^{-1}(\frac{11.1 m}{18 m})

\theta=51.9\° (3)

Now, we firstly need to find T from (2):

T=\frac{mg}{sin\theta} (4)

T=\frac{(28 kg)(9.8 m/s^{2})}{sin(51.9\°)}

T=348.69 N (5)

Substituting (5) in (1):

F=Tcos\theta (6)

F=348.69 N cos(51.9\°)

Finally:

F=215.15 N

Complete the sentence to describe conduction, convection, and radiation. Conduction, convection, and radiation are ways by which
Nutka1998 [239]

Explanation :

Conduction : Conduction is the transfer of heat due to collision between the molecules in the substance.

It is the way of energy transferred in the solid.

Convection : When  air is heated and then travels away from the source that means air caries the heat along.

it is called convection.

It is the way of energy transferred in the air and liquid.

Radiation : radiation generate from the emission of electromagnetic wave.

electromagnetic wave carry the energy away from the source which is emitting the radiation.

It is the way of energy transferred in the vacuum.
