Calculate the mass of wood that has the same energy as 1 g of oil

The power consumed by the razor is 100W.

According to Ohm's law,

Therefore Resistance R = [tex]V^{2}[/tex] / P

Given,

Power in North America P[tex]^{NA}[/tex] = 25 w

Voltage in North America V[tex]^{NA}[/tex] = 120 V

Voltage in Europe V[tex]^{EU}[/tex] = 240 V

Resistance in North America R[tex]^{NA}[/tex] = [tex]120^{2}[/tex] / 25 = 576 Ω

Resistance in Europe R[tex]^{EU}[/tex] = 576 Ω ( Assumed constant )

Power in Europe P[tex]^{EU}[/tex] = [tex]240^{2}[/tex] / 576 = 100 w

Ohm's law describes that the Current across a conductor is directly proportional to the Voltage across those two points.

By conversion unit, 1 kilogram is equal to 10⁶ milligrams or 1000000 milligrams.

We need to know about a conversion unit to solve this problem. Kilogram is the SI unit for length but there are other units which able to determine the length such as gram and milligram. The conversion unit of milligram to kilogram is

1 mg = 10¯⁶ kg

1 mg = 0.000001 kg

From the question above, we know that the question is converting 1 kg to 1 mg, Hence

1 mg = 10¯⁶ kg

multiply by 10⁶

1 kg = 10⁶ mg

The charge will the potential be 100 V =  1.112 x10⁻¹² C

distance is 4.994 × 10⁻⁵m

v = 100V

K = 8.988 x 10⁹ NM²/C²

r = 1.00 μC

charge may be defined as physical quantity which experience force when placed in an electromagnetic field.

It is measured in coulomb (C)

It is represented by the symbol q.

The formula to find how far from a 1.00 μC point charge will the potential be 100V.

V = kq / r     ........1

q = rV/ K

Where

V = Electric potential

q = charge

r = distance

k = Coulomb's constant.

Charge = (1.00 x 10⁻⁶m)(100)/ 8.988 x 10⁹ NM²/C²

q = 1.112 x10⁻¹² C

So, The charge will the potential be 100 V =  q = 1.112x 10⁻¹² C

distance at which it will be 2.00 x 10^2 is given by

using equation 1

V = kq / r

If you travel at the speed of a Boeing 747, which means 570 miles per hour, it will take you about 159 years to reach Saturn.

Saturn has orbiting distance from the sun at a mean distance of about 1.4 billion km or 887 million miles. Calculating from that, it’s from earth would be about 1.29 billion km, adding up to 795 million miles.

So, to calculate the years that it would take to reach Saturn, first, let’s convert the hours to years so that we can find out years in the end.

1 hour can be written down as 0.0001141155 years as per calculation.

So, then the Boeing 747 travels at a speed of 570 miles per 1.1141155 x 10^-4 year

So, to reach to travel a distance of 1 mile, Boeing 747 takes {(1.1141155 x 10^-4) / 570} years.

So, in order to travel 790 million miles, Boeing 747 takes 795,000,000 x {(1.1141155 x 10^-4) / 570} years.

If we calculate it, we get the answer around 159 years.

In the above situation, Archimedes’ Principle is used.

It was given by a Greek Scientist, Archimedes in 246 CE.

According to this principle, the upward buoyant force on a body that is exerted on a body immersed in a liquid is equal to the weight of the liquid displaced by the body.

The formula for Buoyant force is given by the following formula

Force = ρ x g x v

Here  ρ = density of the fluid

g = acceleration due to gravity

v = Volume of the fluid

In the beginning, the cart started from rest and moved to the right. The movement represents positive acceleration

In the middle, there is no change in velocity hence no acceleration. This means that the value of acceleration is zero

A the end, the cart had a negative acceleration which brings the cart to rest.

Acceleration refers to the change in velocity with time. Usually when there is no change in velocity acceleration is zero. The value can also be positive or negative depending on the velocity.

When there is an increase in velocity, the result is positive acceleration but in a situation when there is a decrease in velocity the result is negative acceleration. At the peak pf negative acceleration the result is to put the object accelerating to a stop.

A negatively charged particle released at rest will move towards regions of high potential in this context.

This is defined as the amount of work energy which is required to move a unit charge from one point to another in an electric field.

Negative charges which start from rest, accelerate from regions of low potential and move toward regions of high potential due to the strong Coulomb attraction.

On the other hand, positive charges starting from rest will accelerate from regions of high potential and move towards that of a low potential as a result of it having a weak coulomb attraction which makes it to easily get moved to a potential which has a weak strength.

The type of energy generated by the sun is known as the solar energy. Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun's core and fuse to create a helium atom.

The power of Sun and Stars can be assumed by the process of nuclear fusion reaction. In a fusion reaction, two light nuclei merge to form a single heavier nucleus.

Yes, a friction force to the right acts on the furniture.

The force preventing solid surfaces, fluid layers, and material components from sliding past one another are known as friction. When surfaces in contact move past one another, the friction between the two surfaces transforms kinetic energy into thermal energy (that is, it converts work to heat). As demonstrated by the utilization of friction produced by rubbing pieces of wood together to start a fire, this feature can have dramatic effects. Every time there is motion with friction, such as when a viscous fluid is agitated, kinetic energy is transformed into thermal energy. Wear is a significant side effect of several types of friction that can result in deteriorated performance or component damage. The discipline of tribology includes friction.

Answer:

4.6 s, because that is the time for the object to reach the top of the incline.

Explanation:
that at the top of the incline, the horizontal velocity will be equal to the launch velocity, because there is no longer any force acting on the object in the horizontal direction. The only force acting on the object is gravity, which is acting in the vertical direction. So the only velocity that will be changing is the vertical velocity. The vertical velocity will be changing because of the force of gravity, which is 9.8 m/s2. The equation for the vertical velocity is: vf = vi + a*t, where vf is the final velocity, vi is the initial velocity, a is the acceleration and t is the time. The final velocity in this case is 0 m/s, because the object has reached the top of the incline and is no longer moving in the vertical direction. The initial velocity is 10 m/s, because that is the launch velocity. The acceleration is 9.8 m/s2, because that is the force of gravity. So when you plug all of those values into the equation, you get: 0 = 10 + 9.8*t and you solve for t and you get t = 4.6 s.

There are 56.2 x 10^-6kg or in simple terms 0.0000562 kg in 56.2mg.

This can be explained as 1 kg = 10^6 mg

Or if you want to even simplify it much further, it can be deduced by

1 kg = 1000g and 1 g = 1000mg

This means 1 kg = (1000 x 1000) mg

Which means 1 kg = 1000000 mg or 10^6 mg.

So, to answer this question we have to reverse the process we have done here.

This means 1 kg = 10^6 mg

Which implies 1mg = 1/ 10^6 kg

Or it can be written as 1 mg = 10^-6 kg

So, 56.2 mg = 56.2 x 10^-6 kg and that is your answer.
