Doctor suggest a lens of power -0.5D to a person, Calculate focal length of lens, name the types of lens.​

Answer»

Answer:

it is a concave LENS, because power, radius of CURVATURE , and focal length of concave lens MEASURED in negative form.

Explanation:

we know that,

Power = 1/f(in METERS)

What is black hole and what is inside it?gd mrng! ​

Answer»

Answer:

A black hole is a tremendous amount of matter crammed into a very small — in fact, ZERO — amount of space. The RESULT is a powerful gravitational pull, from which not EVEN light can escape — and, therefore, we have no information or insight as to what life is like inside.

a ball moving with momentum of 5kgm /sec strikes against a wall at an angle of 45 degree and is reflected at the same angle. Calculate the change in momentum​

Answer»

Given :-

<P>
  • P = 5kgm/s
  • Θ = 45°

_____________________________________

From the figure given above, there is no change in perpendicular component and cancel each other.

The initial momentum along the x - axis,

\bf\green{P = P \cos \: Θ }

The final momentum along the x-axis,

\bf\green{P{f}=  - P \cosΘ}

So, change in momentum

\bf\green{∆ \: P = Pf - Pi }  \:  \:  \:  \:   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \\ \bf\green{∆ \: P =  - 2P \cosΘ}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \\ \bf\green{∆ \: P =  - 2 \times 5  \times  \cos45°} \\ \bf\green{∆ \: P =   - 7.071kgm/s} \:  \:  \:  \:

Change in momentum is -7.071 kgm/s

Find the distance and displacement of a particle which ismove a circular path when in complete3/4 part of thecircle. Radius of circle is 28.​

Answer»

ANSWER:

perimeter of circle is =2r

perimeter of circle is = 2× 3.14×28 =175.84

primeter of a circle is 175.84

1 - \frac{3}{4}   =  \frac{1}{4}

displacement \:  =  \sqrt{ {r}^{2} } +  {r}^{2}

complete root r2 +r2

displacement =  \sqrt{2 {r}^{2} }

displacement = 2r

displacement = 2 \times 28 = 56

distance =3/4 ×2r

distance = 3r/2 = 131.88

The Graph given shows the positions of a body art different times.Calculate the Speed of the body as it moves from:(i) A to B(ii) B to C, and(iii) C to D​

Answer»

\Large{\bf{\green{\mathfrak{\dag{\underline{\underline{Given:-}}}}}}}

  • Graph shows the POSITIONS of a body at different times.

\Large{\bf{\orange{\mathfrak{\dag{\underline{\underline{To \: Find:-}}}}}}}

  • Speed of the body,

  • (i) A to B

  • (ii) B to C

\Large{\bf{\red{\mathfrak{\dag{\underline{\underline{Solution:-}}}}}}}

We know that,

\boxed{\pink{\sf Speed \: = \: \dfrac{Distance}{Time}}}

First let's take,

  • A to B

  • Distance covered from A to B =

  • Final distance covered - intial start =

  • 3 - 0 = 3cm

  • Time taken =

  • Final time taken taken - starting time =

  • 5 - 0 = 5s

  • Speed =

  • \sf Speed \: = \: \dfrac{3}{5}

THEREFORE,

  • \boxed{\purple{\textsf{Speed from A to B = 0.6 cm/s.}}}

Second let's take,

  • B to C

  • Distance covered from B to C =

  • Final distance covered - initial start =

  • 3 - 3 = 0cm

This implies that,

  • Body is at rest.

  • Time taken =

  • Final time taken - starting time =

  • 7 - 5 = 2s

  • Speed =

  • Since, distance i.e numerator is 0.

Therefore,

  • \boxed{\purple{\textsf{Speed from B to C = 0 m/s i.e at rest.}}}

Third let's take,

  • C to D

  • Distance covered from A to B =
  • Final distance covered - intial start =

  • 7 - 3 = 4cm

  • Time taken =

  • Final time taken taken - starting time =

  • 9 - 7 = 2s

  • Speed =

  • \sf Speed \: = \: \dfrac{4}{2}

Therefore,

  • \boxed{\purple{\textsf{Speed from C to D = 2 cm/s.}}}

Finally,

  • Speed from A to B = 0.6 cm/s.

  • Speed from B to C = 0 cm/s.

  • Speed from C to D = 2 cm/s.

20. The electronic configuration of an atom 'X' is 1s22s22p63s1. write the symbol of the ion formed by the atom and type of bond it may form? ​

Answer»

<P>Answer:

The energy of atomic orbitals increases as the PRINCIPAL quantum number, n, increases. In any atom with two or more electrons, the repulsion between the electrons makes energies of subshells with different values of l differ so that the energy of the orbitals increases within a shell in the order s < p < d < F. Figure 1 depicts how these two trends in increasing energy relate. The 1s ORBITAL at the bottom of the diagram is the orbital with electrons of lowest energy. The energy increases as we move up to the 2s and then 2p, 3s, and 3p orbitals, showing that the increasing n value has more influence on energy than the increasing l value for small atoms. However, this pattern does not hold for larger atoms. The 3d orbital is higher in energy than the 4s orbital. Such overlaps continue to OCCUR frequently as we move up the chart.
