ANSWER:

Anticlockwise MOMENT = 40 × (50 – 10)

= 1600 dyne cm

Clockwise moment = 20 × (90 – 50)

= 800 dyne cm.

Since anticlockwise moment is greater than the clockwise moment. So, for equilibrium suspend the 40gf away from 50 cm mark.

Then, 1600 = 800 + 40x

⇒ 40x = 800



The 40 g has to be suspended at (50 + 20) = 70 cm.

Answer:

CORRECT OPTION is (B)400 kg m/s, 800 kg m/s

Explanation:

We know that,

In the given case,

Mass = m = 100kg

Initial velocity = u = 4 m/s

FINAL velocity = v = 8 m/s

Initial momentum = Mass * Initial velocity

p = mu

p = 100 * 4

p = 400 kg m/s

Final momentum = Mass * Final velocity

p = mv

p = 100 * 8

p = 800 kg m/s

HEY FRIEND PLEASE CLICK on it and CHECK

Answer:

The weight of the water present is 24.8 g

Explanation:

LET the mass of steam CONDENSED be m.

The heat released by steam is sum of heat released while condensing form stem to ice and heat released while TEMPERATURE is dropped from 100°C to 90°C.  

So,

Q₁  = (m×L) + (m×(100−90)×1)

⇒ Q₁ = 540 m + 10 m

⇒ Q₁ = 550 m

Heat absorbed by 22 g of water to increase its temperature from 20°C to 90°C is :

Q₂ = 22 × (90−20) × 1

⇒ Q₂ = 1540 cal

Equating the two heats,

m = 1540/550

⇒ m = 2.8 g

So,

Total mass = 22+2.8

⇒ Total Mass = 24.8 g

Answer

• Magnitude of DISPLACEMENT of the farmer at end of 2 metre 20 seconds from its initial position is 14.14 m

Given

• A farmer moves along the boundary of a square field of side 10 metre in 40 seconds

To Find

• The magnitude of displacement of the farmer at end of 2 min 20 seconds from its initial position​

Concept Used

Displacement : It is defined as the shortest DISTANCE b/w two points , i.e., final and initial points .

Solution

Side of the square field , s = 10 m

⇒ Perimeter , P = 4s

⇒ P = 4 × 10

⇒ P = 40 m

So farmer moves through the boundary of square field in 40 s .

⇒ 40 m ⇔ 40 s

⇒ 1 m = 1 s

Here , Farmer takes 2 min and 20 s totally to move .

⇒ Total time , t = 2 min + 20 s

⇒ t = 2 ( 60 ) s + 20 s

⇒ t = 120 s + 20 s

⇒ t = 140 s

Since farmer moves a meter per second .

So , distance covered in 140 s = 140 m

Now , No. of rotations completed by Farmer = Total distance / Perimeter

⇒ 140 / 40

⇒ 14 / 4

⇒ 3.5 rounds

For 3 complete rounds displacement is zero . Since closed path .

From attachment ,

For half ROUND STARTING from A Farmer will be at C .

So , apply Pythagoras theorem for finding displacement , d.

⇒ d² = 10² + 10²

⇒ d² = 100 + 100

⇒ d² = 200

⇒ d = 10√2 m

⇒ d = 14.14 m

So , Magnitude of displacement off the farmer at end of 2 metre 20 seconds from its initial position is 14.14 m
