Answer:
1160 ohm
Explanation:
We are given that
R'=580 ohm
Current=3 I
We have to find the resistance of the circuit.
Let R be the resistance of circuit.
In parallel
Using the formula
In parallel combination,Potential difference across each resistance remains same.
Using the formula
Answer:
Uranus and Neptune
Explanation:
The planets beyond Earth are called Giant planets. The other name of the Giant planets is Jovian planets they are, Jupiter, Saturn, Uranus and Neptune.
It is believed that the planets Jupiter and Saturn consist of a solid core and the rest of the mass is in liquid or gaseous form so, they are called gas giants.
The planets Uranus and Neptune have the gases solidified in the form of ice. All the Jovian planets consist of majority hydrogen gas and helium gas.
The planets Uranus and Neptune have the highest proportions of hydrogen compounds
B)
Two bodies with the same vibration frequency that are placed next to each other will exhibit sympathetic vibrations as one body causes the other to vibrate.
False, the pitch of a sound wave is NOT its wavelength
The pitch of sound is akin to frequency. This can be defined as the time that is taken by a wave to complete one cycle (wavelength).
Explanation:
While frequency and wavelength of a wave are related, the relative pitch of the sound can change without changing the wavelength of the wave. An example of this phenomenon is when you hear a wailing ambulance approaching you. The pitch is high as it approaches you but the pitch lowers when it passes you and teh ambulance moves away from you. The wavelength of sound waves did not change but the compression and stretching of the sound wavelengths, respectively, caused the difference in the pitch of the sound.

Answer:
Frequency = 658 Hz
Explanation:
The third harmonics of A is,
The second harmonics of E is,
The difference in the two frequencies is,
delta_f = 1320 Hz - 1318 Hz = 2 Hz
The beat frequency between the third harmonic of A and the second harmonic of E is,
delta_f =
We have calculate the frequency of the E string when she hears four beats per second, then
delat_f = 4 Hz
Hope this helps!
