The diagram below shows the before and after image of a cannon-cannonball system. Initially, the cannon-cannonball system are combined as a single mass at a resting position. After collision, the cannon and cannonball are separated, each having their own velocities.
the 24.6 kg cannonball leaves the 1696.5 kg cannon at a velocity of 184.2 m/s, what is the magnitude of the recoil velocity of the cannon?

Rank the torques on the five doors shown in the figure above from least to greatest. note that the magnitude of all the forces is the same

What produces light and all other electromagnetic waves? a) the photoelectric phenomena b) heated metals c) charged particles d) radioactive samples (pls explain if you can : )

Solar cell a produces 100 joules of energy, when a light source is shown on it for 3 minutes. solar cell b produces 200 joules of energy when the same light source is shown on it for 5 minutes. which solar cell works better? a) solar cell b, because it produces more energy. b) solar cell b, because it generates more power. c) solar cell a, because it produces energy quicker. d) solar cell a, because it generates a greater wattage. eliminate
