Earth around the sun and the moon around the earth
Answer:
475 N/C
Explanation:
As we know that, the electric field in parallel plate capacitor is same (constant) throughout. And is potential gradient.
So, Electric field is given by
Electric field = potential gradient
Here, the potential change is 3.8V and the distance from negative plate to positive plate is 1.6 cm. The potential from negative plate to the center is (1.6/2)cm i.e., 0.8 cm.
But we have to take distance in SI units So, distance=
So, Electric field is
So, electric field is 475 Volts per meter.
Note : Also we can say 475 Newtons per coulomb
Answer:
120.0v drop across the 20.0 resistor
Explanation:
Answer:
Sound waves need to travel through a medium such as solids, liquids and gases. The sound waves move through each of these mediums by vibrating the molecules in the matter. The molecules in solids are packed very tightly. ... Sound travels about four times faster and farther in water than it does in air
