A massless spring (K=800 N/m), attached with a mass (500g) is completely immersed in 1 kg of water. The springs is stretched by 2cm and released so that it starts vibrating. What would be the order of magnitude of the change in the temperature of water when the vibratioins stop completely ? (Assume that the water container and spring receive negligible heat and specific heat of mass =400 J/ kg K, specific heat of water =4184 J/kg K)
A mass of 1kg is hanged through a spring. The spring is stretched through 1cm. What is the energy stared in spring?
A spring with one end attached to a mass and the other to a right support is stretched and released
A spring is stretched by 5cm by a force 10N. The time period of the oscillations when a mass of 2Kg is suspended by it is
When a mass m is hung on a spring, the spring stretched by 6 cm. If the loaded spring is pulled downward a little and released, then the period of vibration of the system will be
Two blocks of masses m_(1) and m_(2) are connected by a massless spring and placed on smooth surface. The spring initially stretched and released. Then :
What is the water equivalent of a substance of mass 2 kg and specific heat capacity 2.4 J g^(-1) K^(-1) ?
Certain amount of heat is given to 100 g of copper to increase its temperature by 21^@C . If same amount of heat is given to 50 g of water, then the rise in its temperature is (specific heat capacity of copper = 400 J kg^(-1) K^(-1) and that for water = 4200 J kg^(-1) K^(-1))
When a mass M is attached to the spring of force constant k , then the spring stretches by . If the mass oscillates with amplitude l , what will be maximum potential energy stored in the spring
Find the increase in mass when 1 kg of water is heated from 0^@C to 100^@C . Specific heat capacity of water = 4200 J kg^(-1) K^(-1) .
