You have a 90 W electrical appliance that is on 24 hours per day. At $0.51 per kWh, how much are you paying daily for electricity to operate this appliance?Show your calculations here:

Answers

Answer 1

Answer:
90 watts = 0.09 KW

Energy = (power) x (time) =
(0.09) x (24) KWh

Cost = (energy) x (unit price) =
(0.09 x 24) x ($0.51) = $1.10 per day (rounded)

(Those are very expensive kWh's.)

A physics student throws a ball thrown horizontally from the top of a building with a speed of 8 m/s. The student measures the height of the building to be 15m.

Answers

Answer:

Following are the solution to the given question:

Explanation:

Please find the complete question in the attached file.

$a_x = 0\n\na_y = -g = -9.81\ \ (m)/(s^2) \n\nv_(iy) = 0 \n\ny = v_(iy) * t+ (1)/(2ay) * t^2 \n\n 15 = (1)/(2) * 9.8 * t^2 \n\nt = \sqrt{(2 * (15)/(9.8))} \n\n$

$= 1.75 \ sec \n\n$

Distance:

$x = v_(ix) * t \n\n$

$= 8 * 1.75\n\n= 14 m$

Using the concept of motion, the answers to the question posed on the motion of a dropped ball are :

Verticalcomponentofacceleration=-9.8m/s²
Horizontalcomponentofacceleration=0
InitialverticalVelocity=0
Timetaken=1.75seconds
Landingdistancefrombuilding=14meters

The vertical component of acceleration is denoted as $a_(y)$ :

The gravitational force acting on the ball in the downward direction has an acceleration of - 9.8 m/s². Hence,

$V_(y) = 9.8 m/s^(2)$

Gravitational force only acts downwards along the vertical, hence, horizontal component of acceleration will be Zero.

$V_(y) = 0$

then the vertical component of x, will be 0

$V_(x)$ = 0

Theinitialverticalvelocity; $V_(iy) is Zero$ :

$V_(iy) = 0$ :

Thetimetaken:

S = 0.5gt² ; S=distance=15meters;g=-9.81

15 = 0.5(9.8)t²

15 = 4.9t²

t² = (15 ÷ 4.9)

t² = 3.061

t = √3.061

t=1.75seconds

LandingDistancefrombuilding:

Horizontal speed × time taken

$V_(ix) * 1.75$

$8 * 1.75 = 14 meters$

Therefore, the ball landed 14 meters away from the building.

Arrange the substances in the table from the MOST to the LEAST ordered particle arrangement
A)
wood, water, neon gas
B)
wood, neon gas, water
water, wood, neon gas
D
water, neon gas, wood

Answers

Answer:

I think the correct answer from the choices listed above is option A. The correct arrangement of the substances according to the most to the least ordered particle arrangement should be wood, water and neon gas. Wood should be the first since it is solid which has the most ordered structure as compared to the liquid and a gas. The neon gas is the last since as a gas it has the least ordered structure.

Answer:

A) wood, water, neon gas

Explanation:

wood, water, neon gas.

The particles of solids have an arrangement that is highly ordered and regular. Liquids have an arrangement that is less ordered, and the particle arrangement in gases is the least ordered and regular of the three states of matter.

Air pollution is an example of a. The underground economy. B. An external shock. C. A nonmarket activity. D. A negative externality.

Answers

Answer:

D. A negative externality.

Explanation:

Particulate pollution is a form of pollution that is responsible for the degradation of the environment.

Particulate matter is also referred to as particle pollution or atmospheric aerosol particles and it can be defined as a complex microscopic mixture of liquid droplets and solid particles that are suspended in air.

An externality is typically an unwarranted cost or benefit by a manufacturer or producer of goods and services that affects a third party.

In Economics, an externality could either be positive or negative depending on its effect on a third party.

A negative externality arises when the production or consumption of a finished product or service has negative impact (cost) on a third party.

In conclusion, air pollution is an example of a negative externality because it causes harm to a third party.
