-- The long line and short line close together at the left side
   of the diagram represent a single-cell battery.
It's the only one in this diagram.
It's a device that stores chemical energy and delivers it on demand.

-- The zig-zag lines with circles around them represent light bulbs.
There are three of them in this diagram.
They are devices used to produce light by dissipating electrical energy.

-- The zig-zag lines without circles, at the top of the diagram,
   represent resistors.
There are two of them in this diagram.
They are devices used to change or control electrical parameters
   within a circuit by dissipating electrical energy.

-- The short straight line between two small circles at the bottom
   of the diagram represents a switch.
There is only one switch in this circuit.
It's a device used to easily and quickly start or stop the flow of current
    past a certain point in a circuit.

In this circuit ...

-- When the switch is closed (as drawn), the light bulb nearest the battery
glows brightest, the light bulb in the middle glows less bright, and the light
bulb on the right side glows dimmest of all.

-- When the switch is open, the light bulb nearest the battery glows, and
neither of the other two light bulbs glows at all.

Which will increase the kinetic energy of an object more, increasing its mass or increasing its speed? Why?

agasfer [191]

Increasing its velocity will add to the kinetic energy more as the formula for kinetic energy is 0.5*m*v^2. (The speed will be squared making it greater)

Equilibrium can occur only if

Answer:

Equilibrium is when the rate of the forward reaction equals the rate of the reverse reaction. All reactant and product concentrations are constant at equilibrium.

An apple hanging from a limb has potential energy because of its height . If it falls ,what becomes of this energy just before i

sineoko [7]

Answer: Just before its hits the ground it becomes kinetic energy and when it hits the ground it becomes in another form of energy (acoustic energy or thermal energy, for example)

Explanation:

Energy is the ability of matter to produce work in the form of movement, light, heat, among others.

In this sense, according to the Conservation of Energy principle: <em>"energy is not created or destroyed, it is transformed."</em>

So, in the case of the apple, its total energy is conserved.

When the apple is hanging from a limb, it has zero kinetic energy $K_{o}=0$ (because it is at rest) and has gravitational potential energy $U_{o}$ , which depends on the mass $m$ , the acceleration due gravity $g$ and the height $h$ :

$U_{o}=mgh$

When the apple falls, just before its hits the ground, this gravitational potential energy transforms in kinetic energy $K_{1}$ (since the apple is moving), which depends on the mass and velocity $V$ of the apple:

$K_{1}=\frac{1}{2}mV^{2}$

When the apple hits the ground, the gravitational potential energy is zero (h=0) and the kinetic energy transforms into some other form of energy (acoustic energy or thermal energy, for example).
