A 5 kg book falls from a shelf. If it lands at a speed of 5.7 m/s, from what height did it fall?
Pachacha [2.7K]

Answer:

57m

Explanation:

speed = 5.7m/s

or 57/10 m/s

so definitely the time taken will be 10 secs

so speed = distance/time taken

5.7= distance/10

distance = 5.7× 10

Distance = 57m

Which one of the following statements accurately describes a characteristic of adolescence?
Yuliya22 [10]

Hi!


Answer D would be the best option.


During the period of adolescence, which is generally between 13-19, the individual goes through a transitional period which is characterized by changes in emotional, physical and mental capacities.

These changes consequently result in the adolescents' desire to be more independent, and to govern their lives as how they deem more fitting, which results in the rebellious nature in the individual.

The other options include characteristics that MAY be seen in individuals, but is not a defining characteristic of adolescence and is not very common.


Hope this helps.

Calculate the electric field at the center of a square
pantera1 [17]

Answer:

E_y=1175510.2\ N.C^{-1}

The Magnitude of electric field is in the upward direction as shown directly towards the charge q_1.

Explanation:

Given:

  • side of a square, a=52.5\ cm
  • charge on one corner of the square, q_1=+45\times 10^{-6}\ C
  • charge on the remaining 3 corners of the square,q_2=q_3=q_4=-27\times 10^{-6}\ C

<u>Distance of the center from each corners</u>=\frac{1}{2} \times diagonals

diagonal=\sqrt{52.5^2+52.5^2}

diagonal=74.25\cm=0.7425\ m

∴Distance of center from corners, b=0.3712\ m

Now, electric field due to charges is given as:

E=\frac{1}{4\pi\epsilon_0}\times \frac{q}{b^2}

<u>For charge q_1 we have the field lines emerging out of the charge since it is positively charged:</u>

E_1=9\times 10^9\times \frac{45\times 10^{-6}}{0.3712^2}

  • E_1=2938775.5\ N.C^{-1}

<u>Force by each of the charges at the remaining corners:</u>

E_2=E_3=E_4=9\times 10^9\times \frac{27\times 10^{-6}}{0.3712^2}

  • E_2=E_3=E_4=1763265.3\ N.C^{-1}

<u> Now, net electric field in the vertical direction:</u>

E_y=E_1-E_4

E_y=1175510.2\ N.C^{-1}

<u>Now, net electric field in the horizontal direction:</u>

E_y=E_2-E_3

E_y=0\ N.C^{-1}

So the Magnitude of electric field is in the upward direction as shown directly towards the charge q_1.

An object acted on by a constant force F moves from point 1 to point 2 and back again. The work done by the force F in this roun
aksik [14]

Answer:

F is non-conservative.

If F were conservative no work would be done in moving back to the original point.       F dot S = W     if the net distance is zero the work done is zero for a conservative force
