Explanation:
The average speed is the displacement of a particle divided into a time in which the displacement occurs. Instead, instantaneous speed is the limit of the average speed as the time interval approaches zero.
<u><em>In physics expressions </em></u>
Instantaneous speed=
b) Speed denotes distance traveled divided by time, and instantaneous speed measures how quickly and in which direction does it move
Answer:
In the parallel plate capacitor
The capacitance will decrease between the plates.
The voltage will increase between the plates.
Explanation:
When the distance between the plates increase, then the voltage also increases as it varies with the separation of plates. However the capacitance will decrease upon increasing the distance. As the capacitance depends upon the electric field between the plates. Field is stronger when the plates are closer so capacitance increase. Field will be weaker upon increasing the distance and hence the capacitance decreases.
When you heat something of cool it down you don't change the substance you might change the why is looks, but it is still the same substance. For example you cool water to 0 degrees Celsius it turns into ice but it still is two parts hydrogen and one part oxygen H2O. Physical changes will change state and/or form but it will still be what it originally was on the molecular level. Hope that helped.
For fundamental frequency of a string to occur, the length of the string has to be half the wavelength. That is,
1/2y = L, where L = length of the string, y = wavelength.
Therefore,
y = 2L = 2*0.75 =1.5 m
Additionally,
y = v/f Where v = wave speed, and f = ferquncy
Then,
v = y*f = 1.5*220 = 330 m/s
Explanation:
Time = Distance/Speed
= 96km / (30km/h)
= 3.2h. (Or 3 hours and 12 minutes)
