During the formation of our solar system, the nebular dust began to cool and sections began to condense. Eventually, small grains stuck to one another via an electromagnetic force. As they grew, gravity helped to speed up the building process until planetesimals were formed. This process is called A) accretion.
B) expansion
C) orderly motion
D) angular momentum

Convection occurs when thermal energy is transferred by the movement of

The ideal gas model is valid if which of the following conditions is true? the gas density is low. the gas density is high. the temperature is low. the temperature is high. the gas density and the temperature are low. the gas density and the temperature are high. the gas density is high and the temperature is low. the gas density is low and the temperature is high.

Adielectric-filled parallel-plate capacitor has plate area a = 30.0 cm2 , plate separation d = 9.00 mm and dielectric constant k = 3.00. the capacitor is connected to a battery that creates a constant voltage v = 15.0 v . throughout the problem, use ϵ0 = 8.85x10-12 c2/n.m2 . find the energy u1 of the dielectric-filled capacitor.
