Answer:
False
Explanation:
The current flowing through a circuit can be computed by using Ohm's law:
where
V is the voltage of the battery
Req is the total resistance of the circuit
Let's now compare the two situations. Let's call R the resistance of each resistor (since they are identical, they have same resistance, R)
- Series configuration: in this case, the total resistance of the circuit is given by
So the current through the circuit is
(1)
- Parallel configuration: in this case, the total resistance of the circuit is given by
So the current through the circuit is
(2)
By comparing (1) and (2), we see that the current in the parallel configuration is greater than in the series configuration:
therefore, the correct answer is false.
Answer;
- Nuclear fusion
Explanation;
-Hydrogen bombs and stars both produce energy with the nuclear fusion. On other side, the Sun and other stars make heat and light by nuclear reactions.
-The first stage of a hydrogen bomb involves a fission explosion which in turn leads to a nuclear fusion. The extreme heat and pressure from the initial atomic blast force together deuterium and tritium (two light gases made of hydrogen). When they are forced together, some of the hydrogen atoms fuse to one another, creating helium.
-This process of fusion releases even more energy per unit of mass than fission does, and the energy released from the fusion reaction also feeds back into the fission reaction, increasing its output.
The sentence can be completed as follows:
"Particles in a SURFACE wave move in an elliptical or circular motion". So Answer D is the correct one.
<span>Explanation: surface waves are waves that move in circular or elliptical motion at the interface between two mediums (for example, between water and air). An example of surface wave is the wave obtained when you throw a stone in the water: the wave produced when the stone touches the water is a surface wave, that moves with concentrical circles around the source.</span>
