relation between potential difference and electric field is given as
so here we know that
d = 3 cm
So now when plates are separated to 4 cm distance carefully
the potential difference between them will change but the electric field between them will remain constant
So at distance of 4 cm also the electric field will be E = 1000 N/C
Answer:
<em>The bicyclist goes at 5 m/s</em>
Explanation:
<u>Motion With Constant Acceleration
</u>
It's a type of motion in which the velocity of an object changes uniformly in time.
The equation that rules the change of velocities is:
Where:
a = acceleration
vo = initial speed
vf = final speed
t = time
It's given a bicyclist is traveling at v0=+25 m/s and decelerates at . We are required to calculate the speed after t=5 seconds.
Applying the formula:
The bicyclist goes at 5 m/s
Each 480-volt, three-phase, wye-connected feeder disconnect with a minimum rating of 100 amperes is required to be ground-fault protected.
A feeder disconnect is the main electrical disconnecting device in an electrical circuit. It provides an accessible location for disconnecting all conductors at one time and is usually located near the source of power. Feeders can consist of cables or busbars.
To be considered a feeder, it must have a voltage that exceeds 50 volts under normal conditions and must supply more than one receptacle or piece of equipment. A feeder disconnect must have a minimum rating of 100 amperes or less and may be rated up to 1000 amperes or higher depending on how much power it supplies to its load(s).

Industrially biomass, living or recently experienced obtain fuel from biological material or by using other industrial purposes are related. Widely, with the goal of obtaining biofuels fibers with cultivated plants, heat and chemicals used to obtain the means of animal and vegetable products. Biomass, organic waste can be burned as a fuel composition. However, geographical impact modified with, coal, organic materials such as oil-free. Are usually measured by dry weight
Chemical equations show how chemicals interact when a reaction occurs. They use symbols and formulas to show the chemical reaction so that chemical names do not need to be written out. They also help keep track of all elements and the number of atoms of each element on each side of the equation.
