606.	Plz answer it fast gain the ponts
Answer» Answer: We are GIVEN 3 resistors each of resistance 6 Ω. Equivalent resistance of resistors in series is more than the individual resistance of each resistor while equivalent resistance of resistance in parallel is less than the individual resistance of each resistor. (i) To get an equivalent resistance of 9 Ω, atleast one six ohm resistor should be connected in series with the other resistors. Since, R eq =R 1 +R 2 9=6+R 2 R 2 =3 Ω ⟹R 2 <6 Ω Connecting the remaining two resistors in parallel will yield an equivalent resistance of 3 Ω. Hence, the first figure shows the configuration of resistors to get equivalent resistor of 9 Ω. (ii) To get an equivalent resistance of 9 Ω, no six ohm resistor should be connected in series with the other resistors. LET one of the branches have only one 6 Ω resistor. Since, R eq 1 = R 1 1 + R 2 1 9 1 = 6 1 + R 2 1 R 2 =12 Ω Connecting the remaining two resistors in series will yield an equivalent resistance of 12 Ω. Hence, the second figure shows the configuration of resistors to get equivalent resistor of 4 Ω. solution

Hence, the first figure shows the configuration of resistors to get equivalent resistor of 9 Ω.

(ii)

To get an equivalent resistance of 9 Ω, no six ohm resistor should be connected in series with the other resistors.

Answer» ANSWER: Correct Question :- A 20 cm long SPANNER is used to open a rusted nut of a motorcycle by applying a minimum force of 60 N. CALCULATE the moment produced. Given :- A 20 cm long spanner is used to open a rusted nut of a motorcycle by applying a minimum force of 60 N. To Find :- What is the moment produced. FORMULA Used :- $\clubsuit$ Moment Formula : $\mapsto \sf\boxed{\bold{\pink{Moment =\: F \times d}}}$ where, F = Force d = Distance Solution :- First, we have to convert distance cm to m : $\implies \sf Distance =\: 20\: cm$ $\implies \sf Distance =\: \dfrac{2\cancel{0}}{10\cancel{0}}\: m$ $\implies \sf Distance =\: \dfrac{2}{10}\: m$ $\implies \sf\bold{\red{Distance =\: 0.2\: m}}$ Now, we have to find the moment produced : Given : Force = 60 N Distance = 0.2 m According to the question by using the formula we get, $\longrightarrow \sf Moment =\: 60 \times 0.2$ $\longrightarrow \sf Moment =\: 60 \times \dfrac{2}{10}$ $\longrightarrow \sf Moment =\: \dfrac{12\cancel{0}}{1\cancel{0}}$ $\longrightarrow \sf Moment =\: \dfrac{12}{1}$ $\longrightarrow \sf\bold{\red{Moment =\: 12\: Nm}}$ ${\small{\bold{\underline{\therefore\: The\: moment\: produced\: is\: 12\: Nm\:.}}}}$

7. A 20 cm long spanner is used to open a rusted nut of a motorcycle by applying an ette of OON. Calculate the moment produced Ans: 12Nm. please send me the solving steps

Answer»

ANSWER:

Correct Question :-

A 20 cm long SPANNER is used to open a rusted nut of a motorcycle by applying a minimum force of 60 N. CALCULATE the moment produced.

Given :-

A 20 cm long spanner is used to open a rusted nut of a motorcycle by applying a minimum force of 60 N.

To Find :-

What is the moment produced.

FORMULA Used :-

$\clubsuit$ Moment Formula :

$\mapsto \sf\boxed{\bold{\pink{Moment =\: F \times d}}}$

where,

F = Force
d = Distance

Solution :-

First, we have to convert distance cm to m :

$\implies \sf Distance =\: 20\: cm$

$\implies \sf Distance =\: \dfrac{2\cancel{0}}{10\cancel{0}}\: m$

$\implies \sf Distance =\: \dfrac{2}{10}\: m$

$\implies \sf\bold{\red{Distance =\: 0.2\: m}}$

Now, we have to find the moment produced :

Given :

Force = 60 N
Distance = 0.2 m

According to the question by using the formula we get,

$\longrightarrow \sf Moment =\: 60 \times 0.2$

$\longrightarrow \sf Moment =\: 60 \times \dfrac{2}{10}$

$\longrightarrow \sf Moment =\: \dfrac{12\cancel{0}}{1\cancel{0}}$

$\longrightarrow \sf Moment =\: \dfrac{12}{1}$

$\longrightarrow \sf\bold{\red{Moment =\: 12\: Nm}}$

${\small{\bold{\underline{\therefore\: The\: moment\: produced\: is\: 12\: Nm\:.}}}}$
