A block of wood has A mass of 200g give the mass in kg showing long conversion
​

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.

Answer:

[tex]\boxed {\boxed {\sf 40 \ Newtons}}[/tex]

Explanation:

We are asked to find the force of a wheelbarrow. According to Newton's Second Law of Motion, force is the product of mass and acceleration.

[tex]F= \ m \times a[/tex]

The mass of the wheelbarrow is 20 kilograms. We are not given the acceleration, so we must calculate it using the following formula.

[tex]a= \frac{v_f-v_i}{t}[/tex]

The wheelbarrow starts at rest or 0 meters per second (initial velocity) and accelerates to reach 10 meters per second (final velocity) in 5 seconds (time).

Substitute these values into the formula.

[tex]a= \frac{ 10 \ m/s-0 \ m/s}{5 \ s}[/tex]

Solve the numerator.

[tex]a= \frac{10 \ m/s}{5 \ s}[/tex]

Divide.

[tex]a= 2 \ m/s/s[/tex]

[tex]a= 2 \ m/s^2[/tex]

Now we know the mass and acceleration of the wheelbarrow

Substitute the values into the force formula.

[tex]F= 20 \ kg \times 2 \ m/s^2[/tex]

[tex]F= 40 \ kg*m/s^2[/tex]

Convert the units. 1 kilogram meter per square second is equal to 1 Newton, so our answer of 40 kilogram meters per square second is equal to 40 Newtons.

[tex]F= 40 \ N[/tex]

Answer:

40 N

Explanation:

We know that

F = ma

and

a = (v - u)/t

So,

F = m(v - u)/t

F = 20(10 - 0)/5

F = 20(10/5)

F = 20(2)

F = 40 N

Assuming you are supposed to write each conversion in scientific notation:

(2) 1 m = 100 cm, so

(67 cm) × (1/100 m/cm) = 67/100 m = 0.67 m = 6.7 × 10 ⁻¹ m

(3) 1 km = 1,000 m, so

(1.2 km) × (1000 m/km) = 1200 m = 1.2 × 10³ m

(4) 1 m = 1,000 mm = 10³ mm, so

(6.2 × 10 ⁻³ m) × (10³ mm/m) = 6.2 mm

(5) 1 m = 1,000,000,000 nm = 10⁹ nm, so

(4.05 × 10³ nm) × (1/10⁹ m/nm) = 4.05 × 10 ⁻⁶ m

(6) 1 g = 1,000,000 µg = 10⁶ µg, so

(3200 µg) × (1/10⁶ g/µg) = 3200 × 10 ⁻⁶ g = 3.2 × 10 ⁻³ g

Answer:

The length of the arrow tells you the size of the quantity in the vector diagram.

The direction of the arrow simply tells you the direction

Answer and Explanation:

A vector in this sense is a thing that has both magnitude (length) and direction.

Say you're walking at a speed of 5 miles per hour. If you keep walking in a straight line, then in two hours you will have walked 10 miles.

This doesn't give any information about where you started or any information about where you ended up after those 2 hours.

This is because "speed" is a scalar. It's a number with no associated geometry. It's just a magnitude. It's the magnitude of velocity.

Velocity is a vector.

Look on a map at where you are right now. Call that the center of the circle. Draw the circle with a 10 mile radius around where you are now.

The length of the arrow represents all of the possible places you could be after a two hour walk.

Which direction the arrow was pointing is what allows your friends to meet you there without checking along a ~63 mile path to find you or searching ~314 square miles to find you if you slowed down or stopped off along the way.

Las dos líneas más largas del terreno de juego se denominarán líneas de banda. Las dos más cortas se llamarán líneas de meta. El terreno de juego será rectangular y la longitud de las líneas de banda deberá ser mayor que las de las líneas de meta. La longitud de la línea de banda debe tener como mínimo 90 metros y como máximo 120 metros. La anchura de la línea de meta debe de tener como mínimo 45 metros y como máximo de 90 metros. Todas las líneas del terreno de juego deberán se líneas continuas y tener la misma anchura, como máximo 12 cm., menos las líneas de meta que deben tener la misma anchura que los postes y larguero de la portería. Todas las líneas que delimitan al campo forma parte del terreno de juego. El terreno de juego puede ser de tierra, césped natural ó césped artificial de color verde según las normas del reglamento de la competición. El terreno de juego está dividido en dos partes iguales por una línea que unirá los puntos medios de las dos líneas de banda. El centro del campo estará marcado con un punto situado en la mitad de la línea media que divide las dos partes iguales del campo, tomando este punto como centro, haremos circulo de un radio de 9,15 metros. También se puede poner un banderín en cada extremo de la línea de media, a una distancia mínima de 1 m al exterior de la línea de banda.

2 h = 120 min

v = 0.1 km/m

distance = v × t

Energy is defined as the measurement of ability to do work.

Here,

Energy is the measurement of ability do work, which is a physical property of matter. Energy is of various types such as kinetic energy, potential energy,  thermal energy, electrical energy, heat energy, etc. Energy and its applications are associated with many laws. The study of energy and the laws associated with them is one of the main branch of physics.

Matter is defined as the substance that has a specific mass and occupies physical space. Atomic particles such as electrons, protons and others are material particles. Thus the study of these matter and material particles is an important branch of physics.

Matter and energy in nature interacts in many ways. Material particles moving moving with particular kinetic energy is an example of matter-energy interactions. These interactions and their studies comes under physics.

Divide distance by speed:

18 meters / 1.5 meters/ second = 12 seconds

Answer: 12 seconds

A bowling lane is 18 meters long. it would take 12 seconds for a 1.5 m/s bowling ball to roll down that lane, therefore the correct answer is the third option

The total displacement covered by any object per unit of time is known as velocity. It depends on the magnitude as well as the direction of the moving object.

The mathematical expression for velocity is given by

velocity= total displacement/Total time

As given in the problem a bowling lane is 18 meters long and the ball is moving with a velocity of 1.5 m/s in the roll-down lane we have to find the time period for the bowling ball to roll down that lane

Total displacement = 18 meters

the velocity of the ball = 1.5 m/s

time =?

By substituting the values in the formula of the velocity

1.5 = 18/t

t= 12 seconds

Thus , it would take 12 seconds for a 1.5 m/s bowling ball to roll down that lane
