Hello I hope you are having a great day :)
Your question: When a light switch is turned on, the light comes on immediately because....
The answer is: the electrons in the wire are instantly "pushed" by a voltage difference making the the light switch on.
Hopefully that helps you :)
Answer:
Explanation:
When the suitcase is being released, it has a horizontal velocity of v0, a vertical velocity of 0 and vertical acceleration of g
The time it takes for it to drop by the vertical distance of α under acceleration g can be solved using the following equation of motion
This is also the time it takes for the suitcase to travel horizontally at the rate of v0. So the horizontal distance it travels is
Answer:
we can say that with a smaller magnitude , the field will point is in same direction
Explanation:
we have given that
solenoid is filled with a diamagnetic material and with air, magnetic field pointing along its axis in the positive x direction
so in small magnitude, the field will point is in same direction
The doppler effect tells us that as an object moves away from another object, the wavelength increases, and vice versa. So, if the universe is expanding and things are moving away from where you are, the wavelength from the light source, such as a galaxy, would increase. Also, if the universe was contracting and things were getting closer to where you are, the wavelength of the light emitted from the galaxy would decrease
