Answer:
def theRoundTrip(movement):
x=0
y=0
for i in movement:
if i not in ["U","L","D","R"]:
print("bad input")
return
if i=="U":
y+=1
if i=="L":
x-=1
if i=="D":
y-=1
if i=="R":
x+=1
return x==0 and y==0
Answer:
atomic radius R = 0.157 nm
metal atomic weight = 72.27 g/mol
Explanation:
given data
parameters a = 0.413 nm
parameters b = 0.665 nm
parameters c = 0.876 nm
atomic packing factor = 0.536
density = 3.99 g/cm³
to find out
atomic radius and atomic weight
solution
we apply here atomic packing factor (x) that is
atomic packing factor (x) =
..................1
put here value we get
atomic packing factor =
R = 
R = 
atomic radius R = 0.157 nm
and
now we get here metal atomic weight that is
metal atomic weight =
....................2
metal atomic weight =
metal atomic weight = 72.27 g/mol
