The molar mass is 352.77g/mol
(I) kinetic energy of the boy when he hits the ground =potential energy
I. e ½mv²=mgh where g is 10ms-²
m=34kg, g=10ms² , h=3m
=34×10×3
=1020j
(i i) v²=u²+2gh
v²=0²+2×10×3
= 60
v=sqrt of 60
Answer:
Yes
Explanation:
Scientists using the latest microscopic technology have found they can move individual atoms around a surface at will, a breakthrough that could have profound implications in the ultra-small world of electronics and even in industry
