Answer:

C a parallel circuit because if one circuit is broken, then the other circuits will still work

Explanation:

Electrical devices can be connected in two different configurations:

- Series configuration: in this configuration, all the devices are connected along the same branch of the circuit. This way, the current flowing through the devices is the same for all the devices. Also, the total resistance of the circuit is equal to the sum of the individual resistances:

$R=R_1+R_2+....+R_n$

- Parallel configuration: in this configuration, the devices are connected in different branches of the circuit. This way, the current flowing through them is different, however they have same potential difference across them. In this case, the total resistance of the circuit is given by

$\frac{1}{R}=\frac{1}{R_1}+\frac{1}{R_2}+...+\frac{1}{R_n}$

The main advantage of the parallel configuration compared to the series configuration is that in a parallel circuit, if one component is turned off/broken, the other components will continue working, since they are connected on separate branches. Instead, in a series circuit, when one component is turned off/broken, al the others also stop working, since they are along the same branch.

So the correct answer is

C a parallel circuit because if one circuit is broken, then the other circuits will still work

At what speed must a 0.6 kg stone be thrown in order that it has a relativistic mass of 0.76 kg? (c = 3.00 x 10^8 m/s) A) 0.6976

soldier1979 [14.2K]

Answer:

The speed of the stone is 0.6138 c.

(B) is correct option.

Explanation:

Given that,

Mass of stone m= 0.6

Relativistic mass = 0.76

We need to calculate the speed

Using formula of rest mass

$m_{r}=\dfrac{m_{0}}{\sqrt{1-\dfrac{v^2}{c^2}}}$

$v^2=(\dfrac{m_{0}^2}{m_{r}^2}-1)c^2$

Put the value into the formula

$v^2=(\dfrac{0.6^2}{0.76^2}-1)\times c^2$

$v=\sqrt{0.37673c^2}$

$v=0.6138c$

Hence, The speed of the stone is 0.6138 c.

Which type of force is the weakest?

laila [671]

Answer:

Explanation:

Ionic bonding is stronger than any of the given intermolecular forces, but is itself NOT an intermolecular force. Ionic bonds are a permanent chemical connection between two atoms, whereas intermolecular forces as a more transient and temporary attraction between independent molecules

The metallic bond is somewhat weaker than the ionic and covalent bond. Ionic bonds are strong electrostatic attraction forces formed between positive and negative ions. This bond is non-directional, meaning that the pull of the electrons does not favor one atom over another.

Ion-dipole forces are the strongest of the intermolecular forces. ... However, hydrogen bonds are still not as strong as ion-dipole interactions. In order from strongest to weakest, the intermolecular forces given in the answer choices are: ion-dipole, hydrogen bonding, dipole-dipole, and Van der Waals forces.

Van der Waals forces are driven by induced electrical interactions between two or more atoms or molecules that are very close to each other. Van der Waals interaction is the weakest of all intermolecular attractions between molecules
