When examining evidence, why might investigators want to be more careful examining chemical properties than physical properties.
tatuchka [14]

Answer:

Please find the answers in the explanation

Explanation:

In examination of any scientific observation, some experiments may be needed to be carried out.

When examining evidence, the investigators might want to be more careful examining chemical properties than physical properties because anything that involve chemical reaction are irreversible. While physical one can be reversible.

Also, reaction can easily take place when examining the chemical properties of some substances.

It is seldom for reaction to take place with physical one.

there can be some complications and danger with chemical properties but less complication and danger with physical one.

Therefore, the investigators will want to be more careful when examining evidence on chemical properties than physical properties due to the given reasons above.

The horizontal and vertical components of the initial velocity of a projectile are 50 m/s and 120 m/s respectively. What is the
katrin [286]

Answer:

<em>50 m/s</em>

<em></em>

Explanation:

In a projectile motion, acceleration is only on the vertical plane, that is, the vertical velocity is the only velocity component that undergoes acceleration under gravitational force. The horizontal component of velocity dos not change with time, and hence is the same as the initial velocity of the projectile.

.If the atoms that share electrons have an unequal attraction for the electrons, the bond is calleda. nonpolar. c. ionic.b. pola
Fittoniya [83]

Answer:

The right option is the 'polar' option.

Explanation:

- The right answer cannot be ionic as sharing of electrons is mentioned. Ionic bonds don't involve the sharing of electrons

- Polarity in terms of bonding is used to describe the situation when one of the atoms involved in the sharing of electrons is more electronegative than the other and pulls the shared electrons more towards itself, thereby inducing a slight positive charge on the other atom and gaining a slight negative charge itself.

- In the absence of this kind of scenario in a covalent bonding that sharing occurs, then it is described as non polar. The two atoms that participate in the sharing of electrons here have similar electronegativities and thereby leave the shared electrons at the middle.

- Dipolar compound is used to refer to organic molecules that are essentially neutral but carry a positive & negative charge in one of their various existence forms.
