why is it not possible to measure a stopping voltage greater than 120V
Q1 Is it possible for a retention factor to be greater than one? Why or why not? Q2. Why is it important NOT to use a pen when writing on the TLC plate?
The outlet voltage inside a house is 120V, but the voltage at the power line that supplies the neighborhood is much higher. A transformer between the power line and the house has 5000 turns in the primary coil and 500 turns in the secondary coil. What is the voltage of the power line supplying electricity to the neighborhood?
Why is the pKa2 of H3PO4 greater than pKa1 and why is pKa3 greater than pKa2?
No handwriting What happens when a voltage greater than the rated voltage is applied to an electrical appliance?
if the total voltage applied in a series circuit of three resistors is 120V and the voltage drop across R1 is 20V and R2 drops 30V, what is the voltage drop for R3?
6.) Explain with as much detail possible why when bonding, fluorine will have a greater pull on bonding electrons compared to iodine. U 7.) Explain with as much detail possible why sodium has a larger atomic radius than magnesium, 8.) Explain with as much detail possible why phosphorus has a larger atomic radius than nitrogen. 9.) Elements are very chemically reactive in groups 1 and 7. Use the trends to explain this observation. 10.) Below are the first thru third...

Is it possible for the velocity of a rocket to be greater than the exhaust velocity of the gases it ejects? Explain: when this happens, the exhaust gas velocity and exhaust gas momentum are in the same direction as that of the rocket. How is the rocket still able to obtain thrust by ejecting the gases?
A stepup transformer decreases voltage from 120V to 6V. The secondary coil has 80 turns and current 50A. Find power, current and number of turns in the primary coil
A transformer steps down voltage from 1000V to 120V. The primary coil carries 2A and has 1000 turn. How many turns does the secondary coil have?
