Pole is the answer.
Actually when we measure, we use metre scale and thread. But since option doesn't have it, so Pole is the answer . Because all curved surfaces has a pole . So, we can directly measure around it.

Prove that the acceleration due to gravity is independent to the mass of the falling body.
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.

Different between Atmosphereric Pressure and Liquid Pressure.
Answer:
Air pressure or atmospheric pressure is the pressure as the force exerted by the collisions of particles in the air. The key difference between air pressure and liquid pressure is that air pressure allows the gaseous state of matter to be compressible, whereas liquid pressure makes a liquid incompressible

A charge feels a 7.89 x 10-7 N force when it moves 2090 m/s at a 29.4° angle to a 4.23 x 10-3 T magnetic field. What is the amount of the charge?
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.

Between which types of elements do ionic bonds occur, and how do electrons act within the bond?(1 point)
nonmetals and nonmetals, electrons shared
metals and nonmetals, electrons transferred
metals and metals, electrons freely moving
nonmetals and metals, electrons shared
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.
What is an ionic bond?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 cocoa was mixed with hot water, but some cocoa settled as it cooled because the solubility went up.
All dissolved substances will come out of solution over time. If the mother waits long enough, then all of the powder will appear at the bottom of the mug.
The cocoa was mixed with hot water, but some cocoa settled as it cooled because the solubility went down.
This would only happen if too much cocoa powder was added in the first place, because the solubility should not change.

A tall tree has more chance to break during storm why
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.
