Answer:

A capacitor

Explanation:

Because it can store electric energy when disconnected from its charging circuit. Commonly used in electronic devices to maintain power supply while batteries change.

Hope this helps! :)

A boy jumps from rest, straight down from the top of a cliff. He falls halfway down to the water below in 0.883 s. How much time

Salsk061 [2.6K]

Answer:

1.25 s

Explanation:

We are given that

Initial velocity of boy=u=0

Time=0.883 s

Let x be the total distance covered by boy in entire trip.

s= $\frac{x}{2}$

We know that

$s=ut+\frac{1}{2}gt^2$

Where $g=10m/s^2$

Substitute the values

$\frac{x}{2}=0\times 0.883+\frac{1}{2}(10)(0.883)^2$

$\frac{x}{2}=3.898$

$x=3.898\times 2=7.796$ m

Again using the above formula

$7.796=0(t)+\frac{1}{2}(10)t^2$

$7.796=5t^2$

$t^2=\frac{7.796}{5}=1.5592$

$t=\sqrt{1.5592}=1.25 s$

Hence, 1.25 s passes during his entire tripe from the top down to the water.

Misha Larkins [42]

Answer:

Part A the answer is the dielectric constant.

Part B Mica- mylar- paper- quartz

Explanation:

The capacity of a capacitor is given by

C = ε ε₀ A / d

Where the dielectric constant (ε) is the value of the material between the plates of the capacitor, we see that as if value increases the capacity also increases.

Another magnitude that we must take into account that the maximum working voltage, the greater the safer is the capacitor

the flexibility of the material must also be taken into account

Part A the answer is the dielectric constant.

Pate B order the materials from best to worst

Mica. The best ever

Mylar Flexible

Paper Low capacity, low working voltage, flexible

Quartz high dielectric, but brittle
