True. Being an electrical engineer, you learn very quickly that current will take All paths of resistance. But, the higher the resistance the lower the voltage. So, if a high resistance is shorted and the current flows through the short, there will be some small voltage across it, so some small amount of current will still flow through the high resistance.
Alexandria became the center for Hellenistic scholarship and culture. It was a great revolution in learning during this era as Alexandria had a library filled with books and important documents which were copied and even stolen. Over 500,000 titles were present in Alexandria's library.
White marble is a white surface
Answer:
Explanation:
a ) speed of passenger = circumference / time
= 2π R / Time
= 2 x 3.14 x 50 / 60
= 5.23 m /s
b )
centrifugal force = m v² /R
= (882 /9.8 ) x 5.23² / 50
= 77.47 N
Apparent weight at the highest point
real weight - centrifugal force
= 882 - 77.47
= 804.53 N
Apparent weight at the lowest point
real weight + centrifugal force
= 882 +77.47
= 959.47 N
c ) if the passenger’s apparent weight at the highest point were zero
centrifugal force = weight
mv² /R = mg
v² = gR
= 9.8 X 50
v = 22.13 m /s
d )
apparent weight
mg - mv² / R
= 882 - (882 / 9.8 )x 22.13²/50
= 882 + 882
= 1764 N
=
