HELP IS NEEDED ASAP<3 Particles q1, 92, and q3 are in a straight line.
Particles
91 =
= -28.1 uC, 92 = +25.5 uc, and
q3 = -47.9 uc. Particles q1 and q2 are separated
by 0.300 m. Particles q2 and q3 are separated by
0.300 m. What is the net force on q3?

The amount of heat required to change liquid water to vapor at its boiling temperature is 2256 kj/kg. the amount of heat required to change liquid mercury to its vapor state at its boiling temperature is 295 kj/kg. one kg of each substance is currently at its boiling point. how will the amount of thermal energy required to change each substance from a liquid to a gas differ?

If you divide a speed in miles per minute by 60, you get the same speed expressed in miles
