They push away from each other or repel due to the same charge they have.
Answer:
19.6 J
Step-by-step explanation:
Before the ball is dropped, it has a <em>potential energy
</em>
PE = mgh
PE = 0.2 × 10 × 9.8
PE = 19.6 J
Just before the ball hits the ground, the potential energy has been converted into kinetic (<em>mechanical</em>) energy.
KE = 19.6 J
Answer:
the new volume is 1.49 L
Explanation:
stp is 0 degrees C and 1 atm.
you need to use the combined gas law formula and solve for v2
i converted the C to Kelvin
v2=p1(v1)(t2)/p2(t1)
v2=1atm(3.6L)(283.15K)/2.5atm(273.15K)
v2=1.49

Answer: If an object has more protons than electrons, then the net charge on the object is positive. If there are more electrons than protons, then the net charge on the object is negative. If there are equal numbers of protons and electrons, then the object is electrically neutral.
Explanation:
