Lithium sulfide is a compound and the atoms are held together by bonds.

Compound is defined as a chemical substance made up of identical molecules containing atoms from more than one type of chemical element.

Molecule consisting atoms of only one element is not called compound.It is transformed into new substances during chemical reactions. There are four major types of compounds depending on chemical bonding present in them.They are:

1)Molecular compounds where in atoms are joined by covalent bonds.

2) ionic compounds where atoms are joined by ionic bond.

3)Inter-metallic compounds where atoms are held by metallic bonds

4) co-ordination complexes where atoms are held by co-ordinate bonds.

They have a unique chemical structure held together by chemical bonds Compounds have different properties as those of elements because when a compound is formed the properties of the substance are totally altered.

The weight of the car that has a mass of 1250000 g would be 12262.5 N

Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.The mathematical expression for Newton's second law is as follows

F = m*a

where F represents the force applied

m is the mass of the object and a is the acceleration of the object .

The major difference between the mass and the weight of an object is that mass of the object is constant throughout the universe while the way it can vary from the positional situation of the object in the universe for example the weight of the weight of the object in the earth would be different than the weight of the same object in some other planet for example The weight of an object  on the Mars would be different than earth.

The weight of any object use the multiplication of the mass and the gravity of the respective planet in our case the weight is measured with respect to the gravity of the earth

Weight = Mass*(acceleration due to gravity)

W= m*g

The value of g for the earth is 9.81 m/s²

As per the given problem the  car that has a mass of 1250000 g

1000 g = 1 kg

1250000 = 1250 kg

Weight = 1250*9.81

            =12262.5 N

Thus ,the weight of the car that has a mass of 1250000 g would be 12262.5 N

Explanation:

this is an example of a question that cannot be solved or why do we sleep too cannot be solved

Answer:

How did life on earth originate?

Explanation:

While there are many views on how life on earth started, especially from a religious stand point, scientists think this idea is "irrational". This is probably because it doesn't make sense how a higher power could create everything that we see on earth today from nothing. While they have tried to create simulations on how life could have possibly formed, they have gotten no answer.

Answer in Observational evidence (b)

The evidence needed to formulate a hypothesis is observational evidence. From keen observations, we are formulating a scientific hypothesis.

Hypothesis is a plausible scientific statement which predicts a process or result of an experiment based on observations. Hypothesis can be made from well established scientific records also.

Some are formulating hypothesis based on some intuitions, while some others are formulated based on inductions or  deductions. An experiment starts from a clear cut hypothesis.

A hypothesis must be testable, falsifiable. A scientific hypothesis must be based on a strict observation and for a considerable time and the observations must support for the statement derived for the solution.

Hence, the evidence is needed for a or a hypothesis to be supported or not supported is observational evidence.

Answer:

Distance: 17 km

Displacement: 7 km

Explanation:

The distance is the total measure of how much he moved.

The displacement is the straight line between the star point and the end point

Answer:

½mv²=mgh

g=½(V²/h)

Explanation:

When an object is held at a height, it posses gravitational potential energy which is mgh, where m= mass, h=height, g=acceleration due gravity

When the object is dropped, the potential energy will be converted to kinetic energy which is ½mv², where V=velocity at which the object moves.

V=∆h/t, ∆h is change in height with respect to time.

½mv²=mgh

Mass cancel out,

g=v²/2h

This implies that g does not depend or is not affected by mass. Hence heavy object and light object will reach the ground at the same time when dropped from the same height. When air resistance is negligible.

From the question, the given charge moving within the magnetic field would have a value of 1.82 x [tex]10^{-7}[/tex] C.

A charge is either a positively or negatively charged particle. When a charge is moving through a magnetic field, it would experience a force which depends on the amount of the charge, its speed, the magnetic field strength and angle. The force on a charge in a magnetic field can be determined by:

F = qvBSin θ

where: q is the charge, v is its velocity/ speed in the field and θ is the angle of deflection of the charge.

Given that: F = 7.89 x [tex]10^{-7}[/tex] N, v = 2090 m/s, B = 4.23 x [tex]10^{-3}[/tex] T and θ = 29.4°.

Thus, the amount of the charge can be determined by;

q = [tex]\frac{F}{vBsin O}[/tex]

  = [tex]\frac{7.89*10^{-7} }{2090*4.23*10^{-3}* Sin 29.4 }[/tex]

  = [tex]\frac{7.89*10^{-7} }{4.340}[/tex]

q = 1.818 x [tex]10^{-7}[/tex]

q = 1.82 x [tex]10^{-7}[/tex] C

Therefore, the amount of the charge that moved within the magnetic field is 1.82 x [tex]10^{-7}[/tex] C.
