The <span>first law of thermodynamics</span><span> is a version of the law of </span>conservation of energy<span>, adapted for </span>thermodynamic systems<span>. The law of conservation of energy states that the total </span>energy<span> of an </span>isolated system<span> is constant; energy can be transformed from one form to another, but cannot be created or destroyed. so assuming no heat losses then heat removed is also 333 J</span>
Answer:
is the mass of librarian.
Explanation:
Given:
- mass of the system,

- velocity of librarian relative to the ground,

- velocity of the cart relative to the ground,

N<u>ow using the principle of elastic collision:</u>
Net momentum of the system is zero.


is the mass of librarian.
To have a force of 3.8x10-8 the two chaarges must be 0.65m apart.
