Kinetic energy-flashlight, and guitar
potential-coal,and composed spring
slega [8]3 years ago
3 0

The answers would be:

POTENTIAL ENERGY

--- Energy of compressed spring

--- Energy of coal

KINETIC ENERGY

--- Energy of a guitar string when plucked.

--- Energy from a flashlight when turned on.

If you'd like to know why:

Energy can be divided into two broad categories, which are:

Potential and Kinetic energy. They differ from each other whereas <em>potential energy</em> is what we call <u>STORED </u>energy and <em>kinetic energy</em> is what we call energy <u>IN MOTION.</u>

Energy is then subdivided further into more specific forms of energy.

In your case, under potential energy you have the compressed spring and coal. A compressed spring's energy is stored through tension, which makes energy MECHANICAL energy. The energy in coal on the other hand comes in the form of CHEMICAL energy, where the energy is stored in the atomic bonds.

Under kinetic energy you have guitar string when plucked (the plucked part is the important clue) and the flashlight turned on. The guitar string creates sound when plucked, so the energy form in this case is what we call SOUND energy. The flashlight on the other hand creates light, which produces RADIANT energy.  The energy here is in motion and it is travelling in waves.

Consider a helium balloon on a string tied to the seat of your stationary car. The windows are closed, so there is no air motion
timama [110]

Answer:

The balloon will move forward.

The density of the air will be greater at the back of the balloon; similar

to the density of air being greater at lower altitudes due to gravitational

attraction because of the weight of the air in an air column.

A block of wood in water rises because of the difference in pressures

on the top and bottom of the block.

GM_ST^2=4 \pi ^2R^3\Rightarrow R= \sqrt[3]{ \frac{GM_ST^2}{4 \pi ^2} }\\\\\\R= \sqrt[3]{ \frac{6.67\cdot 10^{-11} \frac{m^3}{kg\cdot s^2}\cdot2.0\cdot 10^{30}kg( 9.29\cdot 10^8s)^2}{4\cdot 3.14^2} }  \approx 1.42\cdot 10^{12}m

A particle moves along the x-axis with velocity given by v(t)=3t2+6t for time tâ¥0. If the particle at position x=2 at time t=0,
sergey [27]

Answer:

b) 6

Explanation:

Given

v(t)=3t²+6t

X(0) = 2

X(1) = ?

Knowing that

v(t)=3t²+6t = dX/dt

⇒ ∫dX = ∫(3t²+6t)dt

⇒ X - X₀ = t³ + 3t²

⇒ X(t) = X₀ + t³ + 3t²

If  X(0) = 2

⇒  X(0) = X₀ + (0)³ + 3(0)² = 2

⇒  X₀ = 2

then we have

X(t) = t³ + 3t² + 2

when

t = 1

X(1) = (1)³ + 3(1)² + 2

X(1) = 6
