The two conducting rails in the drawing are tilted upwards so they each make an angle of 30.0° with respect to the ground. The v
dolphi86 [110]

Answer:

The current flows through the rod is 14.9 A.

Explanation:

Given that,

Magnetic field = 0.045 T

Mass of aluminum rod  = 0.19 kg

Length = 1.6 m

Angle = 30.0°

We need to calculate the force

Using resolving force

F\cos\theta=mg\sin\theta

F=mg\tan\theta

Put the value into the formula

F=0.19\times9.8\times\tan30

F=1.075\ N

We need to calculate the current flows through the rod

Using formula of magnetic force

F=iLB

i=\dfrac{F}{LB}

Put the value into the formula

i=\dfrac{1.075}{1.6\times0.045}

i=14.9\ A

Hence, The current flows through the rod is 14.9 A.

The two lenses in a microscope are separated by 19.5 cm, and the focal length of the eyepiece lens is 2.75 cm.
Naya [18.7K]

Answer:

Explanation:

a )  If the image of this object is viewed with the eyepiece adjusted for minimum eyestrain (image at the far point of the eye) , the image from object lens must have been formed at the focus of eye lens . So the objective image must have been formed at 19.5 - 2.75 = 16.75 cm from the object lens.

b ) Let the object distance be u

For object lens

v = 16.75 cm , f = .35 cm

1/v - 1/u = 1/f

1/16.75  - 1/u = 1/ .35

.0597 - 1/u = 2.857

1/u = - 2.7973

u = .3575 cm

c ) Angular magnification

= \frac{v_o}{u_o} \times\frac{D}{f_e}

v₀ and u₀ are image and object distance for object lens , D = 25 cm and f_e is focal length of eye lens

= (16.75 / .3575) x( 25 / 2.75)

= 46.85 x 9.09

= 426
