Answer:29 electrons
Explanation: If you look on a periodic table, the atomic number is the amount of electrons it has.
Answer:
The impedance of this circuit is 200 ohm.
Explanation:
Given that,
rms voltage = 120 v
Frequency = 60.0 Hz
rms current = 0.600 A
We need to calculate the impedance
Using formula of impedance
Where, 
= rms voltage
= rms current
Z= impedance
Put the value into the formula
Hence, The impedance of this circuit is 200 ohm.
By definition of average acceleration,
<em>a</em> = (20 m/s - 33.1 m/s) / (4.7 s) ≈ -2.78 m/s²
Vertically, the car is in equilibrium, so the net force is equal to the friction force in the direction opposite the car's motion:
∑ <em>F</em> = (1502.7 kg) (-2.78 m/s²) ≈ -4188.38 N ≈ -4200 N
If you just want the magnitude, drop the negative sign.
Answer:
Making a quick cut left to intercept a pass
Explanation:
It takes more energe to do than running
5.4 x 1014Hz
wavelength x frequency = the speed of light
