Answer:
Explanation:
This is a simple Law of Momentum Conservation problem of the inelastic type. The equation for this is
Filling in:
which simplifies to
5400 + 0 = 3300v
so v = 1.6 m/s to the east, choice B
B- lack of control.
the scientists did not have a proper control group.
Boiling point and acc motivation
The lowest possible temperature is absolute zero. However scientists have not reached this temperature, rather they have come very close to absolute zero.
