3.On a rough horizontal floor, a block is moving with uniform velocity on applying a force of 10 N horizontally. The frictional force acting on the block is ?

ANSWER

10 N

As the block moves in uniform velocity, the acceleration is 0

so F-f = ma

since a=0

Therefor the frictional force acting on it will be

F= f which is equal to 10N

4.

4.

By closing the eyes and gently pressing them by our palms, some specks of brilliant light are seen. How this sensation is got when there is no light entering the eyes?

ANSWERThe pressure on the eye causes activation of retinal ganglion cells and their depolarisation. This results in “phosphene light”. These are the result of biophotonemission of cells in various parts of the visual system.

5.

At what temperature does the Celsius and the Fahrenheit scale read the same ?

ANSWERThe formulas for converting between degree Celsius and degree Fahrenheit are:

°F = (°C * 9/5) + 32°C = (°F - 32) * 5/9

To find the temperature when both are equal, we use an old algebra trick and just set ºF = ºC and solve one of the equations.

°C = (°C * 9/5) + 32°C - (°C * 9/5) = 32-4/5 * °C = 32°C = -32 * 5/4°C = -40

°F = (°F * 9/5) + 32°F - (°F * 9/5) = 32-4/5 * °F = 32°F = -32 * 5/4°F = -40

So the temperature when both the Celsius and Fahrenheit scales are the same is -40 degrees.

6.Uro-hydrosis is a cooling mechanism. Several species of storks and NewWorld vultures exhibit this behaviour. The term is also used to describe the analogous behavior in seals that cool themselves while basking by uro-hydrosis .

What exactly is Uro-hydrosis ?
