Answer: Calcium chloride contains ionic bond.

Copper pennies contain metallic bond.

Hydrochloric acid contains covalent bonds.

Explanation:

Covalent bond is a type of chemical bond in which equal sharing of the electrons takes place between both the atoms.When two atoms with slight or zero difference in their electronegatives  gets combined they form covalent bond.

Calcium chloride contain ionic bond.

Ionic bond is a type of chemical bond in which completer transfer of electrons take place between both the atoms. When two atoms with large difference in their electronegatives gets combined they form ionic bond.

Hydrochloric acid has covalent bond.

Metallic bond is type of chemical bonding which holds together the metal atoms. The electrostatic force between the conduction electrons and the positively charged metal ions. In this bonding ,sharing of electrons is extended over the entire molecular structure.

Copper pennies contain metallic bond.

According to the diagram of the electromagnetic spectrum shown, what would best represent the
iren2701 [21]

The  best represent the size of visible light will be C. Protozoa

The electromagnetic spectrum, gives the overall distribution of electromagnetic radiation by the  frequency or wavelength. All EM waves travel at the speed of light in a vacuum, but over a wide range of frequencies, wavelengths, and photon energies.

Visible light wavelengths cover the range of approximately 0.4 to 0.7 μm. electromagnetic spectrum that the human eye can see is the Visible light. Visible light is a form of electromagnetic (EM) radiation, along with radio waves, infrared, ultraviolet, X-rays, and microwaves. the wavelengths that are visible to most human eyes is generally known as Visible light

the best represent the size of visible light is Protozoa, According to the diagram of the electromagnetic spectrum shown,

A 42.0-kg parachutist is moving straight downward with a speed of 3.85 m/s. (a) If the parachutist comes to rest with constant a
RideAnS [48]

Answer:

-414.96 N

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration

v^2-u^2=2as\\\Rightarrow a=\frac{v^2-u^2}{2s}\\\Rightarrow a=\frac{0^2-3.85^2}{2\times 0.75}\\\Rightarrow a=-9.88\ m/s^2

F=ma\\\Rightarrow F=42\times -9.88\\\Rightarrow F=-414.96\ N

The force the ground exerts on the parachutist is -414.96 N

If the distance is shorter than 0.75 m then the acceleration will increase causing the force to increase

You rub a clear plastic pen with wool, and observe that a strip of invisible tape is attacted to the pen. Assuming that the pen
melomori [17]

Explanation:

It is known that opposite charges tend to attract each other whereas like charges tend to repel each other.

For example, when we rub a plastic pen with wool and it gets attracted towards an invisible tape then it means that there is an opposite charge present on both the objects.

A neutral object also tends to develop a charge when it comes in contact with a charged object.

Thus, we can conclude that the following statements are true.

  • The tape might be positively charged.
  • The tape might be uncharged.
