Monday, 26 October, 20xx.

Diary,

I am so confused and baffled that I need to share my feelings with you. I am sure you will understand me because everybody else at home has stopped to do so. I do reasonably well at academics, but now my mother wants me to top in all SUBJECTS. If I so much as open my mouth to tell her something, dad shuts me up and calls me immature and irresponsible. My elder sister adds fuel to fire by calling me disobedient as I do not run errands for her. My brother keeps teasing me to build muscles LIKE he does by going to the gym. I do not know how to please all of them! I am upset and unhappy. So, I have decided to find a solution: I will try and follow what my PARENTS say to the best of my ability; then I will reason with them that I too am undergoing all the changes of adolescence. I am bound to be REBELLIOUS to a certain extent, but will promise never to insult or hurt any family member. let us see how it goes, wish me luck! BYE,

A mirror forms a real image equal to the size of the object. If focal length of mirror is 10 cmthen the object position from pole of the mirror is(A) 10 cm(8) 20 cm(C) 30 cm W (D) 40 cmD40​

Answer»

Answer:

20 cm

Explanation:

If the object SIZE and the image size are equal, then the object is on the centre of CURVATURE.

we know that

f = r/2

then,

r = 2 f

so, 2 X 10 = 20 cm

What is the relation between wave length and radius of curvature​

Answer»

EXPLANATION:

The distance from the pole to the center of CURVATURE is called (no SURPRISE, I hope) the radius of curvature (r). The distance from the pole to the focal point is called the focal LENGTH (f). The focal length of a SPHERICAL mirror is then approximately half its radius of curvature.

In Ohm's experiment to measure resistance different observation of unknown resistance are 4.12ohm, 4.08ohm,4.22ohmand 4.14ohm .Find average absolute error, relative error and percentage error.​

Answer»

Answer:

Absolute error = 0.02, 0.06, 0.08 and 0.00

Relative error = 9.66 \TIMES 10^{-3}9.66×10

−3

Percentage errror = 9.67%

Explanation:

Absolute error: It is defined as difference between mean VALUE and GIVEN individual value.

Given R₁=4.12, R₂=4.08, R₃=4.22,R₄=4.14

Mean value of all resistance=

R_{mean}R

mean

=(R₁+R₂+R₃+R₄)/4=(4.12+4.08+4.22+4.14)/4

R_{mean}=4.14R

=4.14

Absolute error,

ΔR₁= R_{mean}-R_{1}R

=4.14-4.12=0.02

ΔR₂= R_{mean}-R_{2}R

ΔR₄= R_{mean}-R_{4}R

Relative error:It is the RATIO of absolute mean error and given individual mean value.

ΔR_{mean}R

Relative error = ΔR_{mean}R

/R_{mean}R

mean

=0.04/4.14=9.66\times10^{-3}9.66×10

Percentage error = when relative error is expressed in terms of percentage then percentage error is defined.

Percentage error = (ΔR_{mean}R

Usha swims in a90m long.She covers 180m in one mine minute by swimming from one end to the other and back along the same straight path . find the average and speed velocity of Usha​

Answer»

Distance = 180 m

Time = 1 min = 60sec

Average speed = TOTAL distance covered / total time TAKEN

= 180m / 60 sec

= 3m/s

Displacement = 0m/s ( as usha COME back along the same path so, the intial and final position is same )

Average VELOCITY = displacement/ time

= 0m / 60 s  

= 0m/s

Discuss the law of friction derive the expression for coefficient in terms of angle of repose​

Answer»

ANSWER:

An easy way to measure the coefficient of static friction is to PLACE two objects together and then tilt them until the TOP one slides. The angle at which one object starts to slip on the other is directly RELATED to the coefficient.

When the two objects are horizontal there is no frictional force. As the objects are slowly tilted, the force of static friction must increase from zero to counteract the component of the force of gravity that acts along the interface.

Eventually, as the angle increases, that component of the force of gravity exceeds the maximum value of the force of static friction, and the top object slides off.

How does the angle at which this occurs relate to the coefficient of static friction?

Take the limiting case, the angle reached just before the BLOCK begins to slide, and draw the free-body diagram.

Mass atforce required in acceleration 4kg mass at 5m/s^2 and 3kgmass at 7m/s^2 will be​

Answer»

\bigstar Question

Force REQUIRED in accelerating

  • 4 kg mass at 5 m/s²
  • 3 kg mass at 7 m/s²

\bigstar Solution

We know that

\red{\rm \longrightarrow F=ma}

Here

  • F = force
  • m = mass
  • a = acceleration

Units

  • F = Newton (N)
  • m = KILOGRAM (kg)
  • a = metres/second square (m/s²)

According to the question

We are asked to find force

Therefore

We must find "F"

From the GIVEN question

  • 4 kg mass at 5 m/s²

Hence

  • m = 4 kg
  • a = 5 m/s²

Substituting the values

We get

\rm \longrightarrow F_{1}=4 \times 5 \ N

Therefore

\rm \longrightarrow F_{1}=20 \ N

Similarly

From the given question

  • 3 kg mass at 7 m/s²

Hence

  • m = 3 kg
  • a = 7 m/s²

Substituting the values

We get

\rm \longrightarrow F_{2}=3 \times 7 \ N

Therefore

\rm \longrightarrow F_{2}=21 \ N

Hence

Required forces are

\rm \longrightarrow F_{1}=20 \ N

\rm \longrightarrow F_{2}=21 \ N

A battery of emf 12 V and internal resistance 3 ohm is connected to a resistor. If the current in the circuit is 0.5 A, a. Calculate resistance of resistor. b. Calculate terminal voltage of the battery when the circuit is closed. c. What is the maximum current that can be drawn from the cell. ​

Answer»

Answer:

Explanation:

Given: A BATTERY of emf 10V and internal resistance 3Ω is connected to a resistor. The current in the circuit is 0.5A

To FIND the terminal voltage of the battery when the circuit is closed

Solution:  

Emf of the battery, E=10V

Internal resistance of the battery, r=3Ω

Current in the circuit, I=0.5A

Resistance of the resistor = R

The RELATION for current using OHM's law is,

I=  E/R+r

⟹R+r=  E/I

​⟹R+r=  10/0.5

⟹R=20−3=17Ω

Terminal voltage of the resistor = V

According to Ohm's Law,

V=IR

⟹V=0.5×17

⟹V=8.5V

Therefore, the resistance of the resistor is 17Ω and the terminal voltage is 8.5V

Hope it will be helpful
