Answer:
The distance moved by the boat is 0.70 m.
Explanation:
Given that,
Mass of Romeo = 77.0 kg
Mass of Juliet = 55.0 kg
Distance = 2.70 m
Mass of boat = 80.0 kg
Let the distance moved by the boat is x.
as the center of mass will not change it's position
We need to calculate the distance moved by the boat
Using formula for distance
Put the value into the formula
Hence, The distance moved by the boat is 0.70 m.
Because when your running any experiment there will always be an experimental error so always be ready for it so that you can correct that error in your experiment

Thermal energy is converted to chemical energy.
The equivalent resistance of several resistors connected in series is
the sum of their individual values.
Four 75-ohm resistors connected in series are electrically equivalent
to a single resistor of 300 ohms.
The battery voltage doesn't matter. In fact, it doesn't matter whether the
resistors are anywhere near a battery or not. They could just as well still
be in the little Radio Shack envelope on the top shelf of the storage room.
If they're connected in series, then they're still electrically equivalent to a
single 300-ohm resistor.
