a wire of length l and a resistance r is streached so that length is double and area of cross section halved. how will (a) resistance change, (b) resistivity change

Answer»

ANSWER:

The resistance will be 4 TIMES i.e. 4r and resistivity will be same.

Explanation:

R∝l

R∝1/A

At a certain instant (t = 0) the motorcyclist is due south of the car and is at a distanceof 50m from the car. The shortest distance between the motorcyclist and the car is and the time afterWhich they are nearest to each other after t=0(1) 10 m, 180 (2) 20 m, 10(3) 20 m, 164. (4) 40 m, 1 s.
Answer» Answer: 30m and 1.6sec Explanation: if "t" is the time at that point where the car is moving south DUE east. TAKING distnce moved towards south by car and motorciclist as 20t and 15t Then by using pythagoras theorem, distance, x=d^2=(50-20t)^2 - 15t^2 THUS, differentiating with respect to time t dx/dt = -40(50-20t) - 450t Now, to check maxima and minima - since in the question MINIMUM distance is asked hence the dedifferentiation must be >0 d^2x/dt^2 = 1250t As t cannot be 0 hence >0 thus it is minima thus least distance exists. Now to calculate time t, dx/dt=0 On solving we get, 1250t = 2000 t=1.6sec Now, on putting the value of t in the equation we get x=900 So, d^2=900 shortest DIST d= 30 m

Answer»

Answer:

30m and 1.6sec

Explanation:

if "t" is the time at that point where the car is moving south DUE east.

TAKING distnce moved towards south by car and motorciclist as 20t and 15t

Then by using pythagoras theorem,

distance, x=d^2=(50-20t)^2 - 15t^2

THUS, differentiating with respect to time t

dx/dt = -40(50-20t) - 450t

Now, to check maxima and minima -

since in the question MINIMUM distance is asked hence the dedifferentiation

must be >0

d^2x/dt^2 = 1250t

As t cannot be 0 hence >0 thus it is minima thus least distance exists.

Now to calculate time t,

dx/dt=0

On solving we get,

1250t = 2000

t=1.6sec

Now, on putting the value of t in the equation we get x=900

So, d^2=900

shortest DIST d= 30 m

48.	If y=a-b then percentage error in a and b are 2%&3%. Find maximum % error in y if a=5m and b=3m
Answer» Answer: 9.5% EXPLANATION: If y=a-B then percentage error in a and b are 2%&3%. FIND maximum % error in y if a=5m and b=3m a = 5 ± 2% => a = 5 ± (2/100)5 => a = 5 ± 0.1 b = 3 ± 3% => b = 3 ± (3/100)3 => b = 3 ± 0.09 Y = a - b => y = (5 ± 0.1) - (3 ± 0.09) => y = 2 ± 0.19 maximum % error in y = (0.19/2)100 = 9.5%*

If y=a-b then percentage error in a and b are 2%&3%. Find maximum % error in y if a=5m and b=3m

Answer»

Answer:

9.5%

EXPLANATION:

If y=a-B then percentage error in a and b are 2%&3%. FIND maximum % error in y if a=5m and b=3m

a = 5 ± 2%

=> a = 5 ± (2/100)*5

=> a = 5 ± 0.1

b = 3 ± 3%

=> b = 3 ± (3/100)*3

=> b = 3 ± 0.09

Y = a - b

=> y = (5 ± 0.1) - (3 ± 0.09)

=> y = 2 ± 0.19

maximum % error in y = (0.19/2)*100 = 9.5%

50.	Write an activity to distinguish between balanced and unbalanced force
Answer» Answer: Explanation: Balanced force IMPLIES the force which does not change the object’s state of motion. On the contrary, unbalanced forces are the ONE that results in the change in object’s state of motion. Have you ever observed that whenever you want to move an object, it is either pushed or pulled? In physics, the motion exerted (push or pull) to the object, is termed as force, which ARISES due to the object’s interaction with another one. It is capable of changing the object’s magnitude of velocity, the direction of motion and even the shape and size of the object. Force takes place in pairs; they can be balanced or unbalanced. As we LOOK around ourselves, there are many instances where we can find the occurrences of these two forces. This article excerpt makes an attempt to clear the basic differences between balanced and unbalanced forces. Plzark it as BRAINALIST...
