Can you change how much power you use while exercising?

1 answer:

8 0

Answer:Most treadmills and stationary bikes use electricity, but what if you could produce electricity while exercising? With a pedal-power generator, you can! And you can use the electricity immediately to power a television, computer, stereo or other electronics — or store it in batteries to use it later.

Light from a laser strikes a diffraction grating that has 5500 lines per centimeter. The central and first-order maxima are sepa

WINSTONCH [101]

.Answer:

491.4 nm

Explanation:

The distance between central and first maxima is,

$y=0.455m$

And the distance between screen abnd grating is,

$L=1.62 m$

Now the angle can be find as,

$tan\theta=\frac{y}{L} \\\theta=tan^{-1}(\frac{0.455}{1.62}) \\\theta=15.68^{\circ}$

Now the grating distance is,

$d=\frac{1}{5500} cm\\d=1.82\times 10^{-6}m$

Now with m=1 condition will become,

$\lambda=dsin\theta$

So,

$\lambda=1.82\times 10^{-6}m\times sin(15.68^{\circ})\\\lambda=1.82\times 10^{-6}m\times 0.270\\\lambda=491.4\times 10^{-9}m\\\lambda=491.4 nm$

Therefore the wavelength of laser light is 491.4 nm.

Put the following words in order from smallest to largest: atoms, matter, elements

WINSTONCH [101]

Answer:

Matter, atoms, elements.

Explanation:

Matter is just a name for anything that has mass and takes up space. Therefore, atoms are larger than matter. Atoms are the smallest bits of an element that are still that element, so, elements would be bigger than the atoms that come together to create them!

Hope this helps!

Which of these objects has memetic energy

MA_775_DIABLO [31]

Answer:

A collision of pool balls is an example of kinetic energy being transferred from one object to another. Kinetic energy is the energy of mass in motion.

Explanation:

Do all objects have kinetic energy?

Kinetic and potential energies are found in all objects. If an object is moving, it is said to have kinetic energy (KE). Potential energy (PE) is energy that is "stored" because of the position and/or arrangement of the object.
