While spending the summer on your uncle's horse farm, you spend a week apprenticing with his farrier (a person who makes and fits horseshoes). you observe the way he cools a shoe after pounding the hot, pliable shoe into the correct size and shape. suppose a 850 g iron horseshoe is taken from the farrier's fire, shaped, and at a temperature of 650°c, dropped into a 20.0 l bucket of water at 10.0°c. what is the final temperature of the water after the horseshoe and water arrive at equilibrium? neglect any heating of the bucket and any water that is boiled away as the hot iron enters the water. assume the specific heat of iron is 460 j/(kg·k).

The roller coaster from problem #1 then tops a second hill at 15.0 m/s, how high is the second hill? 91.5 m 79.2 m 80.0 m 68.5 m

According to newton's second law, when the same force is applied to two objects of different masses, a the object with greater mass will experience a great acceleration, and the object with less mass will experience an even greater acceleration, b. the object with greater mass will experience a smaller acceleration, and the object with less mass will experience a greater acceleration, c. the object with greater mass will experience a greater acceleration, and the object with less mass will experience a smaller acceleration, d. the object with greater mass will experience a small acceleration, and the object with less mass will experience an even smaller acceleration.

An object has a weight of 500 on earth what is the mass of this object
