Three rods AB,BC and BD made of the same materical and having the same area of cross section have been joined as shown is the The ends A,C and D are held at temperatures 20^(@)C Cand 80^(@)C respectively If each rod is of same length then find the temperature at the junction B of the three rods .

A ball is thrown upwards with a speed of 20m/s from the ground. Another ball is dropped from rest from a building 80m high at the same time (i) Find the difference in their height after they have fallen for 2s? (ii) If the balls are along the same line of motion, when will they colide?

places A and B are 80km apart from each other on a highway.A car starts from A and other from B at the same time.If they move in the same direction,they meet in 8 hours and if they move in opposite directions,they meet in 1 hour and 20 minutes.Find the speed of the cars.

Shaurya and Arjit take a straight route to the same terminal point and travel with constant speeds. At the initial moment, the positions of the two and the terminal point form an equilateral triangle. When Arjit covered a distance of 80 km, the triangle become right-angled. When Arjit was at a distance of 120 km from the terminal point, the Shaurya arrived at the point. Find the distance between them at the initial moment assuming that there are integral distances throughout the movements described.

A speaks the truth in 75% cases and B speaks truth in 80% cases.Find the percentage that they both agree on the same fact.

In the circuit shown all live resistors have the same volue 200 oms and each cell has an emf 3 volts. Find the open circuit voltage and the short circuit current for the terminals A and B.

In the circuit given as Fig. 14.7, Boojho observed that copper is deposited on the electrode connected to the negative terminal of the battery. Paheli tried to repeat the same experiment. But she could find only one copper plate. Therefore she took a carbon rod as negative electrode. Will copper be still deposited on the carbon rod? Explain your answer.
