3505.	A motorboat starts from rest and morewith uniform acceleration. If it attainsthe velocity of 25 m/s in l0s calculatethe acceleration and the distancetravelled in that time
Answer» Answer Acceleration , a = 2.5 m/s² DISTANCE travelled , s = 125 m Given A MOTORBOAT STARTS from rest and more with UNIFORM acceleration.

A motorboat starts from rest and morewith uniform acceleration. If it attainsthe velocity of 25 m/s in l0s calculatethe acceleration and the distancetravelled in that time

Answer»

Answer

Acceleration , a = 2.5 m/s²
DISTANCE travelled , s = 125 m

Given

A MOTORBOAT STARTS from rest and more with UNIFORM acceleration. If it attains the velocity of 25 m/s in 10 s

To Find

The Acceleration and distance travelled in that time

Concept Used

We need to apply equations of motion .

v = u + at
s = ut + ¹/₂ at²
v² - u² = 2as

Solution

$\rm Initial\ velocity,\; u=0\ m/s \;\;[ \; \bf Since\ starts\ from\ rest \;]\\\\\rm Final\ velocity\ ,v=25\ m/s\\\\\rm Time\ ,t=10\ s\\\\\rm Acceleration,a=?\ m/s^2\\\\\rm Distance,s=?\ m$

$\rm Apply\ first\ equation\ of\ motion.\\\\\implies \rm v=u+at\\\\\implies \rm 25=0+a(10)\\\\\implies \rm 25=10a\\\\\implies \rm a=2.5\ m/s^2\\\\\rm Now\ apply\ third\ equation\ of\ motion\ .\\\\\implies \rm v^2-u^2=2as\\\\\implies \rm 25^2-0^2=2(2.5)s\\\\\implies \rm 625=5\ s\\\\\implies \rm s=125\ m$

3519.	Explain, with the help of a diagram, how convection plays a role in the formation of land breeze and sea breeze.
Answer» Sea Breeze: In the morning, due to HEATING effects of the sun, the land becomes hotter MUCH faster as COMPARED to the sea. As a result, the air over the land becomes warmer as compared to the air over the sea. Warm air (over land) being lighter moves upwards due to convection. Cool air from the sea moves in towards the land to fill the empty space. This is called SEA BREEZE. Land Breeze: In the night, the land becomes cooler much faster as compared to the sea. As a result, air over the sea still REMAINS more hot as compared to the air over the land. Hot air (over sea) being lighter moves AFTERWARDS due to convection. Cool air from the land moves in towards the sea to fill the empty space. This is called LAND BREEZE. Hope It Helps.

Sea Breeze:

In the morning, due to HEATING effects of the sun, the land becomes hotter MUCH faster as COMPARED to the sea.

As a result, the air over the land becomes warmer as compared to the air over the sea.

Warm air (over land) being lighter moves upwards due to convection. Cool air from the sea moves in towards the land to fill the empty space.

This is called SEA BREEZE.

Land Breeze:

In the night, the land becomes cooler much faster as compared to the sea.

As a result, air over the sea still REMAINS more hot as compared to the air over the land.

Hot air (over sea) being lighter moves AFTERWARDS due to convection. Cool air from the land moves in towards the sea to fill the empty space.

$\sf{p(MSD) = \{(p + 1)(VSD) \}}$

$\sf{ = > 1 \: VSD = \dfrac{p(MSD)}{p + 1} }$

$\sf{ = > 1 \: VSD = \dfrac{pk}{p + 1} }$

Let least count be LC

$\sf{LC = 1 \: MSD - 1 \: VSD}$

$\sf{ = > LC = k - \dfrac{pk}{p + 1} }$

$\sf{ = > LC = k \bigg(1 - \dfrac{p}{p + 1} \bigg)}$

$\sf{ = > LC = \dfrac{k}{p + 1} }$

So, FINAL answer is:

$\red{ \boxed{ \blue{ \large{ \rm{ LC = \dfrac{k}{p + 1} }}}}}$

3543.	Draw the circuit diagram of a half waverectifier. Explain its working. What is thefrequency of ripple in its output?
Answer» Answer: Single-phase circuits or multi-phase CIRCUIT comes under the rectifier circuits. For domestic applications single-phase low POWER rectifier circuits are used and industrial HVDC applications require three-phase rectification. The most important application of a PN junction diode is rectification and it is the process of converting AC to DC. Explanation: a single-phase HALF-wave rectifier, either negative or positive half of the AC voltage flows, while the other half of the AC voltage is blocked. Hence the OUTPUT receives only one half of the AC wave. A single diode is required for a single-phase half-wave rectification and three diodes for a three-phase supply. Half wave rectifier produces more amount of ripple content than full-wave RECTIFIERS and to eliminate the harmonics it requires much more filtering.
