Answer:
Explanation:
From the given information:
Let the first weight be = 80 kg
The weight of the buddy be = 120 kg
The weight of Bubba be = 60 kg
Also, since you and Budda are a distance of 4m to each other, then the length to which both meet buddy will be:
The length of the boat be = 4 m
∴
We can find the center of mass of the system by using the formula:
The kinetic energy K given to the helium nucleus is equal to its potential energy, which is
where q=2e is the charge of the helium nucleus, and
is the potential difference applied to it.
Since we know the kinetic energy, we have
and from this we can find the potential difference:
where q=2e is the charge of the helium nucleus, and
Since we know the kinetic energy, we have
and from this we can find the potential difference:
