Nady [450]3 years ago
6 0
Electrically neutral objects can become charged when they gain or lose electric charges. When an object is electrically neutral then the overall charge of the object is Zero. If a neutral object gains negative charges then it will become negatively charged, and if it looses the negative charges (electrons) then it becomes positively charged.

The solution to the polynomial expression since the power of the variable is in the second degree is 6.29 × 10² cm

<h3>What is the power of a variable?</h3>

The power of a variable refers to the exponent of the variable and the highest power of a variable is the degree to which the variable is being raised. From the information given, the highest power of the variable is a polynomial.

Given that:

\mathbf{= 2.150  \times 10^2 \ cm + 7.34 \times 10^2 \ cm - 3.2 \times 10^2 \ cm }

So, since the exponents are in the same power we are going to add them all together multiplied by their exponent.

i.e.

\mathbf{= (2.150 + 7.34 - 3.2)   \times 10^2\ cm }

\mathbf{= 6.29 \times 10^2\ cm }

Mandarinka [93]

Answer. One of the key components of the softgel capsule is the plasticizer used to make the shell elastic and pliable and to minimize brittleness and cracking. The plasticizer usually accounts for 20-30% of the wet gel formulation which can impact the quality of the finished product.
