If size of an image is 10 cm and the magnification produced by a mirror is +1, what will be the size of object?

olya-2409 [2.1K]

Answer:

h = 10 cm

Explanation:

The magnification produced by a mirror is given by :

$m=\dfrac{h'}{h}$

h' is the image size and h is the object size

We have, h = 10 cm, m = +1

So,

$m=\dfrac{h'}{h}\\\\h=\dfrac{10}{1}\\\\h=10\ cm$

So, the size off the object is same as that of the size of the image i.e. 10 cm.

The formulas used to analyze the horizontal and vertical motion of projectiles launched at an angle invlove and use of which fun

Anastaziya [24]

Answer:

Explanation:

The formula to analyze motion in the vertical (or y) dimension is

$A_y=Asin\theta$ which says that the motion in the y-dimension is equal to the magnitude of the A vector times the sin of the angle.

The formula to analyze motion in the horizontal (or x) dimension is

$A_x=Acos\theta$ which says that the motion in the x-dimension is equal t the mignitude of the A vector times the cosine of the angle.

Many times this is used to find the upwards velocity and the horizontal velocity when an overall velocity is given with an angle of inclination.

A magnet in the form of a cylindrical rod has a length of 5.51 cm and a diameter of 0.865 cm. It has a uniform magnetization of

andriy [413]

Answer:

Magnetic dipole moment will be $15.51\times 10^{-3}J/T$

Explanation:

We have given length of the cylinder , that is h = 5.51 cm = 0.051 m

And diameter of the cylinder d = 0.865 cm

So radius $r=\frac{d}{2}=\frac{0.865}{2}=0.4325cm=0.4325\times 10^{-2}m$

So volume of cylinder $V=\pi r^2h=3.14\times (0.4325\times 10^{-2})^2\times 0.051=3\times 10^{-6}m^3$

It is given there is uniform magnetization of $M=5.17\times 10^3A/m$

We have to fond the dipole moment

Dipole moment is equal to $\mu =MV$ , here M is magnetization and V is volume

So $\mu =MV=5.17\times 10^3\times 3\times 10^{-6}=15.51\times 10^{-3}J/T$
