andate reebacPrint A bag filled with lead shots is dropped from a height of h 36.1 m. The total mass of the bag is m 890.0 the lead shots, after the bag hits the ground? The specific heat of lead is c - g. What is the increase in the temperature of 130 J/kqK.
When a manganese bar of mass m is dropped through a height difference Δh, its potential energy changes by the amount mgΔh, where g is the acceleration of gravity, equal to 9.81 m s-2. Suppose that when the bar hits the ground, all that energy is converted to heat, increasing the temperature of the bar. If the specific heat capacity of the material in the bar is 0.479 J K-1 g-1, calculate the height from which the bar must be...
An object of mass m is dropped from height h above a planet of mass M and radius R. Find an expression for the object's speed as it hits the ground. Express your answer in terms of the variables m, M, h, R and appropriate constants.
When a palladium bar of mass mis dropped through a height difference Ah, its potential energy changes by the amount mgah, where g is the acceleration of gravity, equal to 9.81 ms. Suppose that when the bar hits the ground, all that energy is converted to heat, increasing the temperature of the bar. If the specific heat capacity of the material in the bar is 0.244 K g calculate the height from which the bar must be dropped to increase...
A ball of mass 81 kg is dropped from a height of 22 m. What is the height at which the velocity is exactly half of the final velocity with which it hits the ground?
1 A173.0g lead ball at 155°C is dropped into a calorimeter cup containing 210 g of water at 16.0°c. After equilibrium is reached, the temperature of water is increased to 18.2°C. What is the heat capacity of calorimeter? Assume that calorimeter and water are initially at the same temperature. (Specific heat of water is 4186 J/kg. C and specific heat of lead is 128 J/kg.C) 2. An unknown metal sample of 54 g at 108°C is dropped into a calorimeter...
