Which factors affect gravitational potential force but not elastic potential energy

Inga [223]

Answer:

The mass of the object involved and the value of the gravitational acceleration

Explanation:

- Gravitational potential energy is defined as the energy possessed by an object in a gravitational field due to its position with respect to the ground:

$U=mgh$

where m is the mass of the object, g is the gravitational acceleration and h is the heigth of the object with respect to the ground.

- Elastic potential energy is defined as the energy possessed by an elastic object and it is given as:

$U=\frac{1}{2}kx^2$

where k is the spring constant of the elastic object, while x is the compression/stretching of the spring with respect to the equilibrium position.

As we can see from the equations, both types of energy depends on the relative position of the object/end of the spring with respect to a certain reference position (h in the first formula, x in the second formula), but gravitational potential energy also depends on m (the mass) and g (the gravitational acceleration) while the elastic energy does not.

In a certain city, electricity costs $0.20 per kw·h. what is the annual cost for electricity to power a lamp-post for 8.00 hours

UNO [17]

Part a)

per day electricity power consumed when 100 W bulb is used for 8 hours

$P = 8 * 100 = 800 Wh$

for one year consumption

$E = 365 * 800 = 292 kWH$

now the cost will be given

$cost = 0.20 * 292 = $ 58.4$

now when other energy efficient light is used

$P = 8 * 25 = 200 Wh$

for one year consumption

$E = 365 * 200 = 73 kWH$

now the cost will be given

$cost = 0.20 * 73 = $ 14.6$

In a double slit experiment, if the separation between the two slits is 0.050 mm and the distance from the slits to a screen is

meriva

The spacing between the first-order and second-order bright fringes is 3 cm. Hence, this is the required solution.

<h3>What is double slit experiment?</h3>

The double-slit experiment serves as a proof in current physics that both light and matter may exhibit properties of classically defined waves and particles. It also illustrates the inherently probabilistic nature of quantum mechanical events. Thomas Young carried out the first experiment of this kind employing light in 1802, illustrating how light behaves like a wave. It was formerly believed that light was made up of either waves or particles. About a century later, with the advent of modern physics, it was discovered that light may in fact exhibit behaviour like that of both waves and particles. The identical behaviour of electrons was first shown by Davisson and Germer in 1927, and it was later extended to atoms and molecules.

The separation between the slits, d = 0.05mm = 5×10⁻⁵ m

The distance from the slits to a screen, D = 2.5 m

Let x is the spacing between the first-order and second-order bright fringes when coherent light of wavelength 600 nm illuminates the slits,

λ = 600nm = 6× 10⁻⁷ m

We know that the bright fringe is given by :

y = nλD/d

So, the spacing between the first-order and second-order bright fringes is :

x = 2λD/d - λD/d

x = λD/d

x = 6 × 10⁻⁷ × 2.5/5 × 10⁻⁵

x = 0.03 m

x = 3 cm

So, the spacing between the first-order and second-order bright fringes is 3 cm. Hence, this is the required solution.

True or False:A wind is a horizontal movement of air from an area of high pressure to an area of lower pressure.

Taya2010 [7]

Answer:

True

Explanation:

When the air blows from high pressure to an area of low pressure over the surface of the earth it is called wind.

The greater the pressure difference more is the speed of the wind. The instrument used to measure the speed of the wind is called an anemometer.

The winds are named after the direction from which they flow.

Calm winds are the slowest of its kind whereas the gale-winds are the strongest winds.
