A player moves along the boundary of a square ground of side 50m in 200 sec.The magnitude of displacement of the farmer at the end of 11 min 40 sec from his initial position is​

Answer»

Explanation:50 √2  m is the displacement of the player at the end of 11  MINUTES 40 seconds Explanation: Square GROUND of 50 m  sides => perimeter = 4 * 50 = 200 m one round is completed in 200 Sec => Hence speed = 1 m/s DISTANCE Covered in 11 min 40 secs = 700 sec    = 700 m 700 = 200 + 200 + 200 + 100 Hence he has moved 100 m from initial position 50 m on one SIDE  and 50 m at right angle Hence Distance of final position from initial position =  √50² + 50² = 50√2 50 √2  m is the displacement of the player at the end of 11  minutes 40 seconds Learn more: A car travels from stop A to stop B with a speed of 30 km/h and then moves

4) A stone dropped from the top of a well reaches the surface of water in 2 econds, find the velocity of stone while it touches the surface of water,​

Answer»

Here INITIAL velocity (u) = 58.8 m/sFinal velocity (V) = 0 (as it comes to rest on TOUCHING the ground)Time (t) = 6 secondsWe KNOW v = u - at0 = 58.8 - a × 6⇒6a=58.8⇒a= 658.8 ∴a=9.8m/s 2 ∴ The value of acceleration due to GRAVITY = 9.8 m/s 2

Alloys like manganin or constantan are used for making potentiometer wire because it has high _______ and low value of _________co-efficient of resistance. * 1 pointResistance, tempratureResistivity, temperatureTemperature, resistanceTemperature, resistivity​

Answer»

tion:(a) The resistivity of copper wire is very low. The connections are made of thick copper wires to minimize the resistance of CONNECTING wires. Because the connection resistance have not been accounted in the FORMULA, (v Resistance is inversely PROPORTIONAL to cross-sectional area, so thick wire has low resistance).(b) The balance point is obtained in the middle of the meter bridge wire so as to increase the SENSITIVITY of the meter bridge and there by no deflection in the galvanometer.(c) Alloys, such as manganin or constantan are used for making meter bridge wire due to their low temperature coefficient of resistance and high resistivity. Due to which the resistance of the wire does not change with increase in temperature of the wire due to flow of current.Given: A resistance ofRΩ draws current from a potentiometer. The potentiometer has a total resistance R 0 Ω. A voltage V is supplied to the potentiometer.To find an expression for the voltage across R when the sliding contact is in the middle of the potentiometer.Solution:Total resistance is given by,

समान्तर में संयोजित दो प्रतिरोधों R, व R,के लिए, इनके तुल्य प्रतिरोध में सापेक्षिक त्रुटि है (जहाँ R, = (10.0 + 0.1) तथाR,%3D (20.04 0.4)2)(1) 0.08(2) 0.05(3)0.01(4) 0.04​

Answer»

जब दो या दो से अधिक प्रतिरोधों को इस प्रकार से संयोजित किया जाए की प्रत्येक प्रतिरोध में विद्युत धारा का मान एकसमान हो तो इस प्रकार के प्रतिरोधों के संयोजन को श्रेणी क्रम संयोजन कहते है।इस प्रकार के संयोजन में प्रतिरोध का दूसरा सिरा अगले प्रतिरोध के पहले सिरे से जुड़ा रहता है और इसी प्रकार दूसरे प्रतिरोध का दूसरा सिरा तीसरे प्रतिरोध के पहले सिरे से जुड़ा रहता है जैसा चित्र में दिखाया गया है।चित्रानुसार 3 प्रतिरोध R1 , R2 , R3 है ये तीनो श्रेणीक्रम में जुड़े हुए है , तीनो प्रतिरोधों में समान मान की धारा I प्रवाहित हो रही है , तीनो प्रतिरोधों पर विभवांतर V1 , V2 , V3 है। V1 , V2 , V3 का मान ओम के नियम से निकाल सकते है।V1 = IR1V2 = IR2V3 = IR3चूँकि परिपथ में आरोपित कुल विभवांतर Vs है।Vs = V1 + V2 + V3V1 , V2 , V3 का मान रखने परVs = IR1 + IR2 + IR3Vs = I (R1 + R2 + R3)चूँकि हम जानते है की Vs = I RVS का मान ऊपर समीकरण में रखने परI R = I (R1 + R2 + R3)अतःR = R1 + R2 + R3यहाँ R को श्रेणी क्रम में प्रतिरोधों का तुल्य या कुल प्रतिरोध कहते है , यहाँ हमने देखा की श्रेणीक्रम में तुल्य प्रतिरोध का मान सभी प्रतिरोधों के योग के बराबर प्राप्त होता है।नोट : हमने 3 प्रतिरोध लेकर इसको समझा है , लेकिन 3 से अधिक प्रतिरोध होने पर भी ये ही निष्कर्ष इसी प्रकार निकाला जा सकता है।

A solid body weights 2n in air .its relative density is 8.how much will the body weight if places in water? please give the correct ans with explanation ​

Answer»

96NExplanation:Given that,Weight of body in air = 100 N Buoyant force = Weight of liquid displaced Volume of water displaced = 400 cc² DENSITY of water = 1g/cm³ In this case,ρ= m/V m=ρ×V m=1×400 m=400g. We know that,The weight of water displaced isW=m×gW= 2/5 × 9.8W=3.92NNow, weight of the OBJECT in waterW=100−3.92W=96.08W=96N.Hence, the weight of object in water is 96 N.Please MARK it as brainliest .!!!!

1. How to study the anomalous behaviour of water by using Hope's Apparatus?​

Answer»

The anomalous behaviour of water can be studied with Hope's apparatus.In Hope's apparatus, a flat bowl is attached to a cylindrical container.There is provision to attach thermometers above and below the flat bowl on the cylindrical container.Water is filled in the mixture of ice and SALT is put in the flat bowl.Initially both temperature T1 and T2 are identical but as TIME passes, temperature T1 of water in the lower part of the cylinder decreases fast while temperature T2 of water in the upper part of the cylinder decreases comparatively SLOWLY.However, once the temperature T1 of the lower part reaches 4°C, it remains ALMOST stable at the temperature.T2 decreases slowly to 4°C.Thereafter, since T2 starts changing rapidly, it records 0°C first and after that the lower temperature T1 records 0°C temperature.The point of intersection of the TWO curves shows the temperature of maximum density.The behaviour of water between it's temperature from 0°C to 4°C is called anomalous behaviour of water.

The resistance of a conductor is 27Ω. If it is cut into three equal parts and connected in parallel, then its total resistance is​

Answer»

In this CASE, a wire of uniform thickness with a RESISTANCE of 27 is cut into three equal pieces and they are joined in parallel. As we know that the resistance is DIRECTLY proportional to the length of the wire, R∝L, so when the wire is cut into 3, the resistance of the cut wire is reduced to one third of the total resistance. That is, the resistance of each cut wire becomes 27/3= 9 ohms.Now, when these 3 wires are connected in a parallel connection, the total resistance is given as 91+91+91=0.3331=3ohms.Hence, the total resistance is now 3 ohms only.Explanation: MARK as brainliest bro
