A change from one form of energy into another is called conservation of energy. The answer is letter C. you cannot create something and destroy it. An example is eating food. You can see food as how as a physical being. However, when you eat the food, the digestive enzymes in your stomach helps break down the food into smaller form. The chemical energy in the food is being changed into mechanical energy. You need food to perform the necessary activities in your life.

Answer: d. an energy transformation.

Explanation:

Gravitational potential energy is the energy possessed by an object by virtue of its position.

Work is defined as the force leading to displacement of the point of application in the direction of the force.

Law of conservation of energy, energy can neither be created nor be destroyed. It can only transformed from one form to another.

Energy transformation occurs when one form of energy is converted into another form. For example : A body in rest possess potential energy and when it moves potential energy is converted into kinetic energy.

olchik [2.2K]

Answer:

Explanation:

AB = 110 miles

Let the distance of the western station from fire is d.

As according to the diagram, use Sine law

$\frac{d}{Sin 15}=\frac{110}{Sin 133}$

d = 110 x 0.2588 / 0.73

d = 39 miles

The membrane that surrounds a certain type of living cell has a surface area of 4.3 x 10-9 m2 and a thickness of 1.1 x 10-8 m. A

Nadusha1986 [10]

Answer:

The charge resides on the outer surface = $1.245 \times 10^{-12}$ C

Explanation:

Surface area of cell $(A) = 4.3\times 10^{-9} m^{2}$

Separation between two plate $(d) = 1.1 \times 10^{-8} m$

Dielectric constant $(k) = 4.2$

Potential difference $(\Delta V) = 85.7 \times 10^{-3} V$

The capacitance of parallel plate capacitor in free space is given by,

$C = \frac{\epsilon_{o} A }{d}$

Where $\epsilon_{o} =$ permittivity of free space = $8.85 \times 10^{-12}$

The Capacitance of capacitor is increase by $k$ times when it placed in dielectric medium.

$C_{dielectric} = \frac{k \epsilon_{o} A }{d}$

And we know that, $C = \frac{Q}{ \Delta V}$

So charge on the outer surface is given by,

$Q = \frac{k \epsilon A \Delta V }{d}$

$Q = \frac{4.2 \times 4.3 \times 10^{-9} \times 8.85 \times 10^{-12} \times 85.7\times 10^{-3} }{1.1 \times 10^{-8} }$

$Q = 1.245 \times 10^{-12}$

Which statement about convection is correct?

AlekseyPX

D. Convection occurs when heated particles of a material flow toward areas having less thermal energy. This movement of particles can only occur in gases and liquids, not solids.
