10 A 50 g copper mass is heated by placing it in a boiling water at 100°C. It is then placed in a 35g of copper calorimeter containing 120 g of water at 20°C. The final temperature of
the mass and water is 23°C. what is the specific heat capacity of copper? (Take specific
heat capacity of water = 4200 JKg K-) Ans:404 JKg 'K-​

whichever one it is, it's definitely not one that you included on the list you provided.

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

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
