Answer:

Communication is a vital component to the scientific process. It helps the scientist, if he/she was making an invention, tell people or get advice about  the project, which couldn't be done without communication. Scientists need to communicate to learn, get advice, and collaborate with one another.

Their final temperature is 247.84 K.

When two physical systems are linked by a channel permeable to heat, they are said to be in thermal equilibrium if there is no net transfer of thermal energy between them. The zeroth law of thermodynamics is seen during thermal equilibrium.

Given that: container 1 initially held 78.3 kg of liquid at a temperature of 271 K, and container 2 initially held 50.6 kg of the same liquid at a temperature of 212 K.

Let the final temperature be T.

As the materials of both container 1 and 2 is same and the comes thermal equilibrium,

78.3 (271-T) = 50.6 ( T - 212 )

(50.6 + 78.3) T = 78.3*271 + 50.6*212

T = 247.84 K.

Hence, the final temperature is 247.84 K.

This graph shows the potential at the origin as -100 V. The x-axis represents distance from the origin and the y-axis represents the potential.

Potential is the ability to become real or actual. It is the capacity to do something, to become something, or to produce something. Potential is not something that is tangible or visible, but instead is an idea or concept. Potential is the potential to become something greater than what it is currently.

The graph shows that the potential decreases linearly with distance from the origin, indicating that the field has a uniform strength. The graph also shows that the potential at any given distance is equal to the potential at the origin (the y-intercept) minus the product of the distance and the field strength.

In chemistry, +2 charge indicates that if the given atom, molecule, or compound needs to lose 2 of its electrons for becoming a cation.

In chemistry,

We often use two types of symbols, one is positive and the other is negative.

If at the top of any atom/compound/molecule + is written it means that the particular atom/molecule/compound needs to lose 2 electrons, as it has 2 excess electrons, and when the atom loses 2 of its electrons then the octet of the electrons will be formed in the outermost orbit, and the atoms become cationic in the nature.

We know, Ions are usually formed by the losing or gaining of electrons,

So, we can say that, if the atom loses any electrons then + sign will be given similarly when the atom gains any electrons then the negative sign will be given.

The formula for gravitational force between two objects is given as the product of gravitational constant and masses of the two objects, divided by the square of distance between the two objects.

The formula is given as:

= F = (G X M X m) / r²

where,

Force = F

Gravitational Constant = G

Mass of one object = M

Mass of another object = m

Distance = r

According to Newton's universal law of gravitation, The force of attraction between any two bodies is directly proportional to the product of their masses and is inversely proportional to the square of the distance between them.

The removal of the periosteum causes shock, distress, tissue damage, and skin puncture. The fusing of vertebrae increases the stability, strength, and shape of the spine. But it will add stress and increase the rate of spine degradation.

The periosteum is the covering that surrounds the bones and supplies the bone with blood, nerves, and cells they require to develop and heal. The bone receives nutrients and sensations from this.

If the periosteum and the muscle are removed because of the accident, it will cause distress and severe shock. Because the nerve in this is helpful in the sensation of pain caused by tissue damage.

Explanation:

Thousands of avalanches occur in Canada each year. They happen in all regions of Canada, but are more frequent in the mountains of British Columbia, Yukon and Alberta. Avalanches can be triggered by wind, rain, warming temperatures, snow and earthquakes. They can also be triggered by skiers, snowmobiles, hikers, vibrations from machinery or construction.            Avalanche facts:

An avalanche occurs when a layer of snow collapses and slides downhill.

Avalanches are caused by four factors: a steep slope, snow cover, a weak layer in the snow cover and a trigger.

Roads and railway tracks may be rerouted to reduce risks.

Safe avalanches may be triggered in dangerous snow packs.

Avalanches can travel up to 90 km/h.

After one hour, only one in three victims buried in an avalanche is found alive. The most common causes of death are suffocation, wounds and hypothermia.

The flow of blood from into the heart to out of the heart is given as Right atrium→tricuspid valve→right ventricle→pulmonary semilunar valve→pulmonary trunk→pulmonary arteries→lung capillaries→pulmonary veins→left atrium→bicuspid valve→left ventricle→aortic semilunar valve→aorta

The right atrium receives deoxygenated blood from the body through two large veins, the posterior (inferior) and anterior (superior) vena cava.

Through the tricuspid valve, blood is transferred from the right atrium to the right ventricle. Tricuspid valve closure occurs when the ventricle is full to stop blood from returning to the atrium.

Through the pulmonary vein, blood that has been oxygenated by the lungs enters the left atrium.

Blood can go from the left atrium into the left ventricle when the mitral valve is open. When the ventricle is full, the mitral valve closes to prevent blood from returning to the atrium.

Blood may move from the heart to the aorta and from there to the rest of the body thanks to the aortic valve.

The force divided by the product of the wire length and current through the wire gives the strength of magnetic field. The magnetic field here is 0.1 Tesla.

A magnetic field can be produced from the deflecting coil or wire carrying current. The magnetic field lines produced will be perpendicular  to the field lines from the electric field.

The force acting on the combined field is the product of the magnetic field strength B, length of the wire L, and the current passing  through the wire I as written below:

F = B I L

Given that the length L = 0.50 m

current I =  8 A

and force f = 0.40 N.

Thus, magnetic field strength B = F/I L
