You (in the x' frame) are moving with v = +5 m/s with respect to the x frame. if your initial position in each frame is om, what are the positions in each frame after 3 s have passed? x: -15 m x': 15 m answer 1: - 15 m answer 2: 15 m

Selma made a diagram to compare convection and radiation. which label belongs in the area marked x? must involve temperature differences between substances or objects only occurs when molecules are in direct contact involves the movement of fluids based on density differences can occur where there is little or no matter

Matter is needed to transfer thermal energy bya. conductionb. convectionc. radiation d. both a & b.

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?
