Explanation:

molecular formula consists of the chemical symbols for the constituent elements followed by numeric subscripts describing the number of atoms of each element present in the molecule. The empirical formula represents the simplest whole-integer ratio of atoms in a compound.

Answer:

The symbollic representation of a molecule of an element or a compound present in a molecule is called molecular formula.

For example: molecular formula of sodium chloride is NaCl.

Explanation:

Distance traveled = steady speed * time duration = 8m/sec * 8 sec = 64 meters

Answer:

64 m

Explanation:

Multiply 8 m by 8.

We have that the amount of the charge q is

[tex]q=1.8*10^{-7}[/tex]

From the Question we are told that

Force [tex]F=7.89 x*10^{-7}[/tex]

Velocity [tex]V=2090m/s[/tex]

Angle [tex]\theta=29.4[/tex]

Magnetic field [tex]B=4.23 * 10^{-3} T[/tex]

Generally, the equation for Force F is mathematically given by

[tex]F=qVBsin\theta\\\\q=\frac{F}{VBsin\theta}[/tex]

[tex]q=\frac{7.89 x*10^{-7}}{4.23 * 10^{-3} T*sin29.4*2090m/s}[/tex]

[tex]q=1.8*10^{-7}[/tex]

In conclusion

The amount of the charge q is

[tex]q=1.8*10^{-7}[/tex]

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.

Answer:

Im pretty sure that its, the metals and nonmetals, electrons transferred.

Between metals and nonmetals, types of elements do ionic bonds occur, and electrons transferred within the bond,therefore the correct answer is option B.

When two similar or dissimilar atoms form bonds with each other by transferring their valence electron the bond is known as the ionic bond.

The ionic bond is the result of the transfer of the electrons

Ionic bonds are formed between the pair of one electronegative atom and an electropositive atom.

Ionic, covalent, and hydrogen bonds are the three basic types of chemical bonds that are used to generate these chemical compounds from their component atoms.

Ionic bonds are created when electrons are transferred between two bond-forming pairs that can be distinguished by their electronegativity.

Thus, Between metals and nonmetals, types of elements do ionic bonds occur, and electrons are transferred within the bond, therefore the correct answer is option B

The airplane refuels between city A and continues on to city B. It travels at an average speed of 733.9km/h. If the trip takes 2.4 hours, what is the flight distance between city A and city B?

Answer:

yes

Explanation:

because the strong winds and the weight and there are more things to break

Explanation:

A tall tree may have more resistance to the wind since it has more mass ( branches, leaves). That means the wind has more mass to push against. Winds may also be stronger at a higher level. Tall trees have been growing longer and have more chances to have been compromised by insects, animals, fungi and so on. They also have less flexibility since they need to be more rigid to hold up the mass of branches they have.
