Add 35 to 215. then divide by 25. you should get x=10
Answer: DC Current
Explanation:
Battery is a source of constant potential difference and it will create a constant voltage across any conductor
due to this constant voltage difference the current in this conductor will remain constant
So here since the voltage across the conductor is constant so we can say that current in the conductor will remain constant and hence this is known as DC current.
While for variable current in direction and magnitude is to be obtained only when the conductor is connected with AC voltage source as we know that AC voltage is variable with magnitude and direction both
A battery is the power source for DC type of current. A battery is a source of constant potential difference that produces a constant current unlike in AC source where the voltage and hence the current changes its polarity continuously.Hence, the current produced by battery is direct current and not Alternating current.
Hope this helps........ Stay safe and have a Merry Christmas!!!!!! :D
The study of motion is called kinematics.
Answer:
When walking towards the back of a bus while it moves forward its apparent velocity seems slower than it actually is with respect to the ground.
Explanation:
- When a someone follows a moving bus from behind by walking then the apparent speed of the bus is slightly slower by the same magnitude as the speed of walking because both are moving in the same direction.
- This is the concept of relative velocity when the apparent velocity of the same object appears different to different viewers at the same time being on different frame of motion.
- When the same bus is observed from a point on the road the speed of the bus will appear greater than the former case discussed above because the bus here is moving with respect to a stationary observer.
(a)The window panes are transparent
(b)The colors of the panes are due to the wavelengths of light that the glass allows to pass through.
<h3>What are trasparent glasses?</h3>
The glasses which allows the light rays to pass through them are called as the transparent glasses.
or visible light is electromagnetic radiation within the portion of the electromagnetic spectrum that is perceived by the human eye.[1] Visible light is usually defined as having wavelengths in the range of 400–700 nanometres (nm),
corresponding to frequencies of 750-420 terahertz, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths
Hence the window panes are transparent the colors of the panes are due to the wavelengths of light that the glass allows to pass through.
