Answer» ANSWER: HEY mate... Explanation: Net force, F 2=82+62 N F2=100 N and hence, F= 10N ACCELERATION, a = F/m= 10/5= 2m/s2 If the net force F makes an angle BETA(b) with the horizontal, then the acceleration will ALSO make an angle beta (b) with the horizontal . this is because the acceleration is always in the direction of force. Tan b =6/8 =3/4 = 0.75 Hence, b = tan-1(0.75)= 36.9o *Hope* *this* *helps* uh!❤️

6.

Please answer.... anybody

Answer»

ANSWER:

HEY mate...

Explanation:

Net force, F 2=82+62 N

F2=100 N and hence, F= 10N

ACCELERATION, a = F/m= 10/5= 2m/s2

If the net force F makes an angle BETA(b) with the horizontal, then the acceleration will ALSO make an angle beta (b) with the horizontal . this is because the acceleration is always in the direction of force.

Tan b =6/8 =3/4 = 0.75

Hence, b = tan-1(0.75)= 36.9o

Hope this helps uh!❤️

Answer» The current through the galvanometer is 1.071 A. Explanation: Given that, AB = 2 Ω BC=4Ω CD = 4 Ω DA = 8Ω Galvanometer resistance = 10 Ω Potential difference between A and C = 5 V We need to calculate the potential difference Using KIRCHHOFF's current law at node B $\dfrac{v_{1}-5}{2}+\dfrac{v_{2}-v_{1}}{10}-\dfrac{v_{1}}{4}=0$ $3v_{1}+2v_{2}=50$ ....(I) Using Kirchhoff's law at node D $\dfrac{v_{2}-5}{8}+\dfrac{v_{1}-v_{2}}{10}-\dfrac{v_{2}}{4}=0$ $-9v_{2}+4v_{1}=25$ .....(II) From EQUATION (I) and (II) $35v_{2}=125$ $v_{2}=\dfrac{125}{35}$ $v_{2}=3.57\ V$ Put the VALUE of v₂ in to the equation (I) $3v_{1}+2\times3.57=50$ $v_{1}=\dfrac{50-2\times3.57}{3}$ $v_{1}=14.28\ V$ We need to calculate the current through the galvanometer Using formula of ohm's law $I=\dfrac{V_{2}-v_{1}}{10}$ Put the value into the formula $I=\dfrac{14.28-3.57}{10}$ $I=1.071\ A$ Hence, The current through the galvanometer is 1.071 A.

The four arms ABCD of a Wheatstones network have the following resistances: AB = 2 Ω, BC=4 Ω, CD= 4 Ω and DA= 8 Ω. A galvanometer of resistance 10 Ω is connected between B and D. Find the current through the galvanometer, when the potential difference between A and C is 5 V.

Answer»

The current through the galvanometer is 1.071 A.

Explanation:

Given that,

AB = 2 Ω

BC=4Ω

CD = 4 Ω

DA = 8Ω

Galvanometer resistance = 10 Ω

Potential difference between A and C = 5 V

We need to calculate the potential difference

Using KIRCHHOFF's current law at node B

$\dfrac{v_{1}-5}{2}+\dfrac{v_{2}-v_{1}}{10}-\dfrac{v_{1}}{4}=0$

$3v_{1}+2v_{2}=50$ ....(I)

Using Kirchhoff's law at node D

$\dfrac{v_{2}-5}{8}+\dfrac{v_{1}-v_{2}}{10}-\dfrac{v_{2}}{4}=0$

$-9v_{2}+4v_{1}=25$ .....(II)

From EQUATION (I) and (II)

$35v_{2}=125$

$v_{2}=\dfrac{125}{35}$

$v_{2}=3.57\ V$

Put the VALUE of v₂ in to the equation (I)

$3v_{1}+2\times3.57=50$

$v_{1}=\dfrac{50-2\times3.57}{3}$

$v_{1}=14.28\ V$

We need to calculate the current through the galvanometer

Using formula of ohm's law

$I=\dfrac{V_{2}-v_{1}}{10}$

Put the value into the formula

$I=\dfrac{14.28-3.57}{10}$

$I=1.071\ A$

Hence, The current through the galvanometer is 1.071 A.

40.	What is image? What is the difference between virtual image and real image?
Answer» Answer: An IMAGE may be defined as that point, where the light rays coming from an object meet or APPEARS to meet after reflection or REFRACTION. A real image is formed when the rays of light after reflection or refraction actually meet at some point whereas a virtual image is formed when the rays of light after reflection or refraction APPEAR to meet at a point. Real image is inverted and virtual is erect.. HOPE IT'S HELPFUL...

What is image? What is the difference between virtual image and real image?

Answer»

Answer:

An IMAGE may be defined as that point, where the light rays coming from an object meet or APPEARS to meet after reflection or REFRACTION.

A real image is formed when the rays of light after reflection or refraction actually meet at some point whereas a virtual image is formed when the rays of light after reflection or refraction APPEAR to meet at a point.

Real image is inverted and virtual is erect..
