When osmium goes from a solid to a liquid and finally a gas, the element has undergone _____.

A fan blows the air and gives it kinetic energy, an hour after the fan has been turned off, the kinetic energy turns into thermal energy.

The fact that all energy is conserved causes a heat flow, which raises internal (or thermal) energy, as the air molecules slow and lose kinetic energy.

Kinetic energy, which may be seen in the movement of an object, particle, or group of particles, is the energy of motion. Any moving item uses kinetic energy, such as a person walking, a baseball being thrown, a piece of food falling from a table, or a charged particle in an electric field.

The energy of a body in motion, or kinetic energy (KE), is essentially the energy of all moving objects. Along with potential energy, which is the stored energy present in objects at rest, it is one of the two primary types of energy.

Here is the difference between contact forces and non-contact forces:

Contact forces are forces that result from two objects coming into physical contact with each other. Non-contact forces are forces that result from the interaction of objects that are not in contact with each other.

The force resultant is 10N.

We need to know about force resultant to solve this problem. The force resultant can be described as the sum of force according to the magnitude and direction. It can be written as

∑F = F1 + F2 + .... + Fn

where ∑F is force resultant, F1 is the first force and Fn is the n-force.

From the question above, the parameter given is

F1 = 5 N

F2 = 5 N

Because of the same direction, the force will be added up each other.

∑F = F1 + F2

∑F = 5 + 5

∑F = 10 N

Hence, the force resultant is 10N.

For a pure substance, the melting temperature range is low

The melting point range is widened as a result of impurity addition, which lowers the melting point. The melting point range is reduced because pure substances have greater melting points.

The typical definition of the melting point is the temperature at which a substance transforms from a solid to a liquid.

The melting point of a liquid is the temperature at which the liquid transforms from a solid to a liquid under atmospheric pressure. This is the location where the liquid and solid phases are equally present.

By placing a tiny amount of an organic solid into a tiny capillary tube, affixing it to the stem of a thermometer centred in a heating bath, slowly heating the bath, and observing the temperatures at which melting begins and is complete, it is possible to determine the melting point of an organic solid.

The correct answer is Option B) Open.

A schematic can tell an electrician that the switches are normally open

until the sensor senses smoke.

A simple, understandable graphical representation of a plan or model is called a schematic diagram. Simple lines and symbols are used in schematics to convey details like what, how, and where. A schematic diagram's primary role is to highlight circuit components and the relationships between them. Schematics are a very useful tool for troubleshooting since they show which parts are connected in series or parallel and how.

An example of an electrical switch is one that is normally open. A typically open switch remains "off" when it is not compressed. The inside electrical connections are to blame for this. In a typically open switch, the contacts are open when the switch is off. This indicates that the switch is "off" because the electrical connection is damaged.

It takes 16.5 seconds to reach its top speed of 80.0 km/h, starting from rest.

A branch of physics called kinematics, which was evolved from classical mechanics, defines how points, bodies, and systems of bodies (groups of objects) move without taking into account the forces that propel them. The discipline of kinematics is sometimes thought of as a subfield of mathematics and is frequently referred to as the "geometry of motion." Any known values of the location, velocity, and/or acceleration of points inside the system are declared as initial conditions for a kinematics issue, together with the geometry of the system. The position, velocity, and acceleration of any unidentified system components can then be calculated using geometrical considerations.

Where [tex]v[/tex] is the final velocity and [tex]v_{0}[/tex] is the initial velocity, we utilize the formula [tex]v = v_{0}+at[/tex] (because the train starts from rest), [tex]a= 1.35\frac{m}{s^{2} }[/tex], [tex]v_{0} = 80.0\frac{km}{h} = 22.22\frac{m}{s}[/tex]

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.

An object is said to be accelerated if there is a change in its velocity. The change in the velocity of an object could be an increase or decrease in speed or a change in the direction of motion.

Acceleration is a vector quantity as it has both magnitude and direction. It is also the second derivative of position with respect to time or it is the first derivative of velocity with respect to time.

Average acceleration refers to the rate at which the velocity changes. We divide the change in velocity by an elapsed time to find out the average acceleration of anything.

final speed = 14 m/s

initial speed = 0

time taken = 10 seconds

Average acceleration = change in speed / change in time
