HYDROGEN GAS + OXYGEN GAS= HYDROGEN PEROXIDE H2+O2=H2O2 HYDROGEN PEROXIDE IS A LIQUID BECAUSE HYDROGEN PEROXIDE CAN NEVER BE A SOLID BECAUSE TWO LIQUIDS CAN NEVER FORM A GAS IT IS IMPOSSIBLE NO MATTER THE CONDITION
Answer:
2. electromagnets can be made stronger by adding more coils to the solenoid.
3. electromagnets can be made stronger by increasing the strength of the electrical source.
Explanation:
Electromagnets are not permanent, they act as magnets when current runs through its coils. They can be stronger by increase the current that goes through the coil surrounding them,. This can be done two ways: 1) increasing the actual current intensity, or 2) increasing the number of coils that wrap around them.
Heres a simple answer
Galileo Galilei was an Italian polymath. Galileo is a central figure in the transition from natural philosophy to modern science and in the transformation of the scientific Renaissance into a scientific revolution.
Answer:
179.3 cells
Explanation:
The lamp requires a current of 60W/220V = 0.273A
The dry cells each have an internal resistance of 1Ω.
The number of cells required in series equals 220V divided by the cell's voltage minus their internal voltage drop under a load current of 0.273A.
= 220V/(1.5V–1Ω*0.273A)
=179.3 cells
