V, (Р 1. A balloon containing 600 cm? of air at a pressure of 0,828 kPa escapes from a child's hand in a shopping centre. It rises and when it reaches the roof, the volume has increased to 700 cm3. Calculat the pressure on the balloon at this height. (assume that the temperature in the shopping centre remains constant). Answer .P, Vi Pq Vz 496,8 P2 (100) 10,8281Pa) (600) = P2 (100)
P2 = 0,70 kPa

2. Calculate the temperature of in the shopping centre if the girl pumped 0,2 moles of air into the balloon. Convert the temperature into °C

2.22/3.33 points | previous answers tamucolphysmechl1 4.pre.002. ask your teacher my notes question part points submissions used on a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 2.40 m/s. (a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
