a spiral spring is compressed by 0.2m calculate the energy stored in the spring if the force contact is 400Nm-1​

Describe different biomes. what are some adaptations that organisms (plants or animals) must have to live in each biome?

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?

Argon, neon, and xenon are examples of
