Answer:
0.64 m
Explanation:
The first thing is calculate the center of mass of the system.
now multiplying every coordinate x by the mass of each object (romeo, juliet and the boat) and dividing all by the total mass taking by reference the position of juliet.
X_cm = 1.4589 m
When the forces involved are internals, the center of mass don't change
After the movement the center of mass remains in the same distance from the shore, but change relative to the rear of the boat.
X_cm= 2.10 m
this displacement is how the boat move toward the shore.
2.10-1.46= 0.64 m
Answer:
Living Things
Explanation:
Physical science is the study of the inorganic world. That is, it does not study living things. (Those are studied in biological, or life, science.) The four main branches of physical science are astronomy, physics, chemistry, and the Earth sciences, which include meteorology and geology.
Answer:
The force between the charges are not affected.
Explanation:
Given;
distance between two equal charges, R = 2m
The force between the charges is given by;
Therefore, the force between the charges are not affected.
1) Because you have a lower chance of getting electrocuted, 2) 1.DON'T plug a bunch of stuff into one outlet or extension cord, 2.Make sure all electric cords are tucked away neatly, 3.DON'T ever climb the fence around an electrical substation, 4.DON'T yank an electrical cord from the wall, 5.Keep electrical stuff far away from water, 6.Ask a grown-up for help. 3) <span>Always determine if there is power to a circuit or wire using a voltmeter. Never touch any part of a circuit if you did not verify yourself that the the power is off(disconnected). { Trust but verify :President R. Reagan} Having turned off or disconnected the power assure that it cannot be accidentally turned on again by another person. Your Welcome.</span>
Answer:p Pulls down on the object changing inertia creating an affect in momentum
