Answer:

Berries is the correct answer because it is the produce in your pyramid and as each living thing is devoured by another there is less energy. For instance the berry has the most energy because it’s energy has just come from the sun. But then an insect eats it and consumes most of its energy but some energy is released into the atmosphere. Then a rodent eats the bug and consumes its energy but yet again some energy is released into the atmosphere. So each time there is less and less energy. Does that help any?

Explanation:

it’s energy has just come from the sun. But then an insect eats it and consumes most of its energy but some energy is released into the atmosphere.

A class of students performed the heat transfer experiment shown in the picture. In the experiment, three plastic dishes were pa

balandron [24]

The method of heat transfer used in the experiment is radiation.

Radiation is a method of heat transfer in which there is no material medium that conveys heat. Heat travels through empty space and causes the temperature of objects to rise.

In this case, there was no material medium that conveyed heat from the lamp to the dishes containing the plants. Heat from the lamp traveled through space and reached the dishes. This is an example of heat transfer via radiation.

If we assume that the metallic plates are perfect conductors, the electric field in their interiors must vanish. given that the

Svetlanka [38]

here the charge density of metal plate is given as

$charge density = \sigma$

now the electric field is given Gauss law

$\int E. dA = \frac{q}{\epsilon_0}$

now here E = constant

so we will have

$E. \int dA = \frac{q}{\epsilon_0}$

Since total area on both sides of plate will be double and becomes 2A

$E. 2A = \frac{q}{\epsilon_0}$

$E = \frac{q/A}{2\epsilon_0}$

$E = \frac{\sigma}{2\epsilon_0}$

Now if we will find the electric field inside the metal plate

Then as we know that total charge inside the plate will always be zero

so we have

$E = 0$

Suppose a car is traveling at +25.0 m/s, and the driver sees a traffic light turn red. After 0.340 s has elapsed (the reaction t

scoundrel [369]

First, we will get the distance traveled before the driver applied the brakes.
distance = velocity * time
distance = 25*0.34 = 8.5 m

Now, we will calculated the distance that the car traveled after the driver applied the brakes. To do this, we will use the equation of motion:
<span>vf^2 = vi^2 + 2*a*d where:
</span>vf = zero, vi = 25 m/s and a = -7 m/s^2
Note: The negative sign is only to show deceleration
d = <span> 1/2*(625) /(7) = 44.6428 m

The total stopping distance =</span> 8.5 + 44.6428 = 53.1428 m

Gauss's Law states that the net electric flux, , through any closed surface is proportional to the charge enclosed: . The analog

Natali [406]

The analogous formula for magnetic fields is the Ampere's law.

To find the answer, we need to know about the Ampere's law of magnetism.

<h3>What's Ampere's law of magnetism?</h3>

Ampere's law states that the close line integral of magnetic field around a current carrying loop is directly proportional to the current enclosed within it.

<h3>What's is the mathematical expression of Ampere's law?</h3>

Mathematically, Ampere's law is

B•dl= μ₀I

Thus, we can conclude that the analogous formula for gauss law is the Ampere's law in magnetism.
