Neutron; Possesses a charge of 0. It is situated in the Nucleus and Has a Mass of "B"
Electron: Has a charge of -1. Found in the Orbitals of the atom and has a mass of "C"
Answer:
0.3 Coulomb charge flows through the toy car.
0.9 Joules of energy is lost by the battery
Explanation:

a)
Current drawn from the battery = 0.50 mA = (0.50 × 0.001 A)
milli Ampere = 0.001 Ampere
Duration of time current drawn = T = 10 min = 10 × 60 s = 600 s
1 min = 60 seconds
Charge flows through the toy car be Q


0.3 Coulomb charge flows through the toy car.
b)

Voltage of the battery = V = 3.0 V
Current drawn from the battery = 0.50 mA = (0.50 × 0.001 A)
Duration of time current drawn = T = 10 min = 10 × 60 s = 600 s

H = 0.9 Joules
0.9 Joules of energy is lost by the battery
Wavelength decreases as frequency increases.
Imagine a heart rate graph. As the heart beats faster, frequency increases and the time between heartbeats decreases (wavelength).
