A microscope has an objective lens with a focal length of 14.0mm . A small object is placed 0.80mm beyond the focal point of the
Nikolay [14]

Answer:

A. 260 mm

B. - 18

C. 175

Explanation:

A

The expression for the lens equation is

\frac{1}{f} = \frac{1}{u} + \frac{1}{v}

\frac{1}{14.0mm} = \frac{1}{14.80 mm} + \frac{1}{v}

\frac{1}{v} = \frac{1}{14.0} - \frac{1}{14.80}

v = 259 mm

   = 260 mm or 26 cm (to 2 s.f)

On being introduced to the laws of thermodynamics, a student retorted, “When the brakes of a moving car are applied, the kinetic
inn [45]

Answer:

No, not at all. This kinetic energy of car is converted/lost in the form of sound and heat under the tyre when driver apply brakes.

Explanation:

This law states that energy can neither be created nor destroyed but it changes from one form to the other.

In this case reduction of kinetic energy of car does not contradict the law but it changes into heat and sound energy. When driver apply brakes we hear the sound of Tyre due to friction with the road. The tyre become hot too.

So it is not in contradiction to the law of conservation of energy (First Law of Thermodynamics).

Please mark branliest if you are satisfied with the answer. Thanking you in anticipation.
