Question

In a compound atoms of element 'Y' form
C.C.P. lattice and those of element 'X' occupy
2/3rd of tetrahedral voids. The formula of the
compound will be
1) X,Y 2) X,Y 3) X,Y. 4) X,Y
2-3​

Answer 1

Answer:

a particle is projected up with speed 50 m/s

u = 50 m/s (upward)

g = 10 m/s² (downward)

time of motion, t = 2u / g = 2×50/10 = 10s

maximum height achieved:

h_{max}=\frac{u^2}{2g}=\frac{50^2}{2 \times 10} = \frac{2500}{20}=125\ mh
