A copper container of mass 84 g contains 84 g of water at 10 °C.46 g of water at 100 °C is mixed with the water in the copper container. What is the final temperature of the water?
(Specific heat capacity of water
= 4 200 J kg- °C, specific heat
capacity of copper = 400 J kg-1 °C-))

A 10 °C
30 °C
B 20 °C
D 40 °C

multiply 2kg by latent heat of vap

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
