Projectile Motion - one question.

AI Thread Summary
The discussion focuses on a projectile motion problem involving a diver who jumps off a platform at a speed of 7 m/s and lands in the water after 1.5 seconds. The calculated horizontal distance from the takeoff point is 10.5 meters, while the height of the diving platform is determined to be approximately 11.02 meters. The equations used include X = Vot for horizontal distance and h = 1/2 gt^2 for vertical height. There is a slight discrepancy in the height calculation, with one participant arriving at 11.03 meters. The solutions provided are generally consistent with the physics of projectile motion.

X= Vot I get same answer 10.5

h = 1/2 gt^2 I get 11.03
 
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
Thread 'Correct statement about a reservoir with an outlet pipe'
The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
