The current decreases as the overall resistance increases. In addition, if one bulb is removed from the “chain” the other bulbs go out. ... If light bulbs are connected in parallel to a voltage source, the brightness of the individual bulbs remains more-or-less constant as more and more bulbs are added to the “ladder”.
Explanation:
In washing machine, the electrical energy is converted in kinetic energy then the mechanical energy is converted into thermal (heat) energy.
Answer:
If the thrust is increased, the aircraft accelerates and the velocity increases. This is the second part sited in Newton's first law; a net external force changes the velocity of the object. The drag of the aircraft depends on the square of the velocity. So the drag increases with increased velocity.
Answer:
The speed of the sound wave is 350 m
Explanation:
Given
Frequency of sound wave = 1000Hz = 1000 (since 1 = 1 Hertz (Hz))
Wavelength of sound wave = 35 cm
Speed of sound wave = ?
All waves have same the relation among frequency, sound and speed which is given by
v=fλ , where
v is the speed
f is frequency
λ is wavelength
Therefore, the speed of sound wave = 1000 x 35 cm
= 35000 cm
= 350 m
Hence the speed of the sound wave is 350 m
Answer:
M L1 = m L2 torques must be zero around the fulcrum
M = m L2 / L1 = .3 kg * 28 cm / 22 cm = .382 kg
