an electric bulb has power 500 watt. what does it means
Answer:
The bulb consumes electrical energy at the rate of 500 Watts
1 Watt = 1 Joule/sec where the joule is the unit of energy
Electric energy is often expressed in kw-hrs
This means that 1 kilowatt of power is used for 1 hour
1 kw-hr = 1000 joules/sec * 3600 sec = 3.6E6 joules of energy

5. How much does a 20 m x 10 m x 8 m swimming pool filled with water weigh? Assume that water has a density of 62 kg/m'.
Explanation:
First of all we calculate the volume which is 20m×10m×8m= 1600m^3 and then multiply the density by the volume to get the mass which will equal to 99200kg therefore the weight will be
Weight
mass × acceleration due to gravity
=99200kg × 10m^s^2
=992000N

a 16 Watt bulb is used for 5 hrs. what is the energy consumed by the bulb
Energy = (power) x (time)
Energy = (16 watt) x (5 hours)
Energy = 80 watt-hours
or
Energy = 0.08 Kilowatt-hours
or
1 watt = 1 joule/second
5 hours = 18,000 seconds
Energy = (16 joule/sec) x (18,000 sec)
Energy = 288,000 Joules
Explanation:
A unit of electricity is represented in kilowatt-hour (KWh). To calculate units, you need to find the energy consumption. It is easy, just multiply power with time.
(16×5 ) watt-hour=80Wh.
Convert it to kilowatt-hour i.e 0.08 KWh/day.
So 0.08 KWh is the energy consumption for one day.

Desarrollar un diagrama de flujo para un programa que solicite la base y la altura y calcule el área de un triangulo
Queremos crear un diagrama general para calcular el área de un triangulo.
Este será algo como:
Definir variablesPedirle al usuario que introduzca los valores deseados (de las variables).Leer los valores deseados y asignarlo a la variable correspondiente.Realizar la operación para calcular el área.Mostrar en pantalla el resultado.Como naturalmente habra algunas variaciones segun el programa que utilicemos, lo voy a escribir de forma bastante general.
Primero definamos nuestras variables:
Por ejemple, en fortran usariamos algo como:
real:: B, H, A
Donde B será la variable que usaremos para la base, H para la altura, y A para el área.
Luego tenemos que escribir en pantalla algo que le diga al usario que debe introducir la base y el area.
Luego el programa debe ser capaz de leer ese input.
con algo de la forma:
B = read*input 1
H = read*input 2
Una vez tenemos definidas las variables, simplemente calculamos el área del triangulo:
A = H*B/2
Finalmente la podemos mostrar en pantalla con algo como:
print(A).
Lo que nos mostraría el valor del área.
Concluyendo, el diagrama en general sería:

If you wanted to know the location of a vehicle that ran out of gas after taking a zigzag route through the city, which quantity would be
most useful?
a. the vehicle's speed
b. the vehicle's distance
c. the vehicle's direction
d. the vehicle's displacement
Explanation:
the vehicles displacement, since displacement deals with position
To know the location of a vehicle that ran out of gas after taking a zigzag route through the city, the quantity that would be most useful is the vehicle's displacement.
In physics, the term quantity refers to something that can be measured.
Displacement is a vector quantity. Displacement simply means distance covered in a specified direction.
Notice that we want to find out the location of the vehicle after it ran out of gas. In this case, we don't only need to know the distance covered by the vehicle but also the direction in which the distance was covered in order to enable us to track the vehicle.
Hence, we need to find out the vehicle's displacement.

Lois Price came up with a brilliant idea of creating a 1,500m perfectly circular track. In order to do so she wanted
to know her distance and displacement at four different locations. Starting at the TOP of the circle, what are her
distance and displacement if she travels... (HINT - Remember the circumference of a circle)
a. quarter way around the track
Isoo
b. half way around the track
4
Р A
C. 4 around the track
d. an entire lap
dist = 375
Her distances and displacement are;
[tex]\begin{array}{|l|c|c|}\mathbf{Location}&\mathbf{Displacement}&\mathbf{Distance}\\&&\\a. \ Quarter \ way \ around&\dfrac{750 \cdot \sqrt{2} }{\pi} m &375 \ m\\&&\\b. \ Half \ way \ around&\dfrac{1500}{\pi} m&750 \ m\\&& \\C. \ Three \ quarter\ way \ around&\dfrac{750 \cdot \sqrt{2} }{\pi} m&1,125 \ m\\&&\\d. \ Entire \ lap&0&1,500 \ m\\\end{array}\right][/tex]
The reason the above values are correct are as follows:
The known details are:
The length of the circular track, C = 1,500 m
The required details;
Her distance and displacement at four locations starting at the top of the circle, as follows;
At the top, the starting point, the displacement = The distance = 0
a. A quarter way round the track;
The radius of the circular track, r = C/(2·π)
∴ r₁ = 1,500 m/(2·π) = (750 m)/π
The displacement a quarter way round the track, s₁² = r² + r²
∴ s₁² = ((750 m)/π)² + ((750 m)/π)²
s₁ = ((750 m)/π)·√2
The displacement a quarter way round the track, s₁ = ((750·√2)/π) m
The distance a quarter way round the track, d₁ = C/4
∴ d₁ = 1,500 m/4 = 375 m
The distance a quarter way round the track, d₁ = 375 m
b. The displacement half way around the track, s₂ = r + r
∴ s₂ = r + r = (750 m)/π + (750 m)/π = (1,500 m)/π
The distance moved half way round the circular track, d₂ = C/2
∴ d₂ = 1,500 m/2 = 750 m
The distance moved half way round the circular track, d₂ = 750 m
C. The displacement 3/4 way round the track, s₃ = s₁ = (750 m)/π)·√2
The distance moved 3/4 way round the circular track, d₃ = (3/4) × 1,500 m = 1,125 m
D. The displacement for an entire lap, which is back to starting point at the TOP, s₄ = 0
The distance traveled in one lap = The circumference of the track, C = 1,500 m
Therefore, we have the following displacement and distances at the four different locations;
[tex]\begin{array}{|l|c|c|}\mathbf{Location}&\mathbf{Displacement}&\mathbf{Distance}\\&&\\a. \ Quarter \ way \ around&\dfrac{750 \cdot \sqrt{2} }{\pi} m &375 \ m\\&&\\b. \ Half \ way \ around&\dfrac{1500}{\pi} m&750 \ m\\&& \\C. \ Three \ quarter\ way \ around&\dfrac{750 \cdot \sqrt{2} }{\pi} m&1,125 \ m\\&&\\d. \ Entire \ lap&0&1,500 \ m\\\end{array}\right][/tex]

when an Apple falls towards the earth moves to meet the apples.Is this true?If yes'why is the earth motion not noticeable?
Oh, yes. It's definitely true.
The answer to your question is:
Because the Earth has something like (6 x 10²⁴) times as much mass as the apple has.
So when equal, opposite gravitational forces act on both of them, the apple's downward acceleration toward the Earth is something like (6 x 10²⁴) times as much as the Earth's upward acceleration toward the apple.
The apple doesn't spend too much time falling, before it hits the ground and both bodies stop moving toward each other. In that time, the apple travels something like (6 x 10²⁴) times farther than the Earth does.
So if the apple falls a mile down from the branch of the tree, then the Earth moves something like 0.000 000 000 000 000 000 011 inch up toward it.
THAT's why Earth's motion is not noticeable to us.

You ride your skateboard to school and tell all your friends your rode at speed of 25 miles per hour. They know this cannot be true because they know
when you left the house and when you arrived at school
how far school is from your house and what time school starts
the distance between your house and school and how long it took you to get there
the distance between school and your house and the direction you traveled
Answer:
The correct answer is "The distance between your house and your school, and how long it took you to get there." This is the proper answer choice because mph is miles per hour. Meaning you can travel 25 miles in just one hour. Speed in such form is used for measuring distance, or time. Hope it helped.
