Work done = force x distance
work done = 15 x 3
work done = 45J
Answer:
Phosphorus
Explanation:
Phosphorus needs 3 electrons to complete its outter most shell of electrons
Answer:
The angular speed (in rev/s) when her arms and one leg open outward is 1.161 rev/s
Explanation:
Given;
moment of inertia of a skater with arms out, = 3.1 kg.m²
moment of inertia of a skater with arms in, = 0.9 kg.m²
inward angular speed, = 4 rev/s
The angular momentum of the skater when her arms are out and one leg extended is equal to her angular momentum when her arms and legs are in.
Therefore, the angular speed (in rev/s) when her arms and one leg open outward is 1.161 rev/s
i can't comment but do you have a pic of the work you need help with?
Magnetic field is produced by the magnet which will flow through any attractive item or even substance such as ferrofluid. Happy I could help:)
